Anatomy Of The Human Body – Systems Made Easy

One thing we all have in common are the systems in place which help maintain the day to day running of our bodies. However, not many people are aware at just how complex the human body is and how truly amazing the body is even down to the cellular level.

In the first of a series of posts on the anatomy of the human body, we will be breaking down and going deeper to look at how wonderful the human body is. First of all we will be looking at the various systems the body uses, then after the different types of tissue and try to unravel the complexity of cells.

All Systems Go…

Some of the most basic functions we encounter with the day to day operation of our bodies involve such a complex number of systems to work simultaneously in order for us to be able to do all we do from one day to the next.

The human body as an organism consists of TRILLIONS of cells, which are able to perform various functions through the access to an external environment. What this means, is that over time cells have evolved to specialize in a particular area to enable the smooth running of the machine that is reading this right now (I’m talking to YOU).

A very clear organizational structure has been devised to ensure all basic and complex processes required for us all to function, can be carried out and executed over and over, day after day. Let’s imagine you have just eaten a nutritious meal and you feel full and content, after you have swallowed said meal, here are the various processes involved once you have eaten that fillet steak or plant based dish.

The Wonder Of You

You may be aware of a few of the systems in place as they are self-explanatory which help bind the body and enable a symbiotic relationship for life to exist, some may come as a surprise. There are a total of eleven systems and I will be running through what they are.

The Integumentary System which you may be more familiar with the term known as skin. This acts to protect the body from various kinds of damage, such as loss of water or damages from the exterior. The integumentary system includes hair and nails along with being waterproof and to protect the deeper tissues.

It excretes waste, and regulate body temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature. In the majority of land vertebrates with significant exposure to sunlight, the integumentary system also provides Vitamin D synthesis.

The body system composed of bones, cartilages, ligaments and other tissues is known as the Skelatal System, which perform various essential functions for the human body. Bone tissue is a hard, dense connective tissue that forms the majority of the adult skeleton, the internal support structure our body. In the areas of the skeleton where whole bones move against each other (shoulder joints or knees) cartilages, a semi-rigid form of connective tissue, provide flexibility and smooth surfaces for movement.

The Muscular System is composed of specialized cells called muscle fibers. Their function is contraction. Muscles, attached to bones or internal organs and blood vessels are responsible for movement. The majority of movement in the body is the result of muscle contraction. The integrated action of joints, bones, and skeletal muscles produces obvious movements such as walking and running. Skeletal muscles also produce some more subtle movements that result in various facial expressions, eye movements and respiration.

You’re Getting On My Nerves

The Nervous System is an organized group of specialized cells which not only receive stimuli but also conduct impulses to and from all parts of the body. These cells are long and string like. The nervous system consists of the brain, spinal cord, sensory organs and all the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts…fabulous!

Another important part of the puzzle is the Circulatory System, also known as the cardiovascular system, is a vast network of organs and blood vessels that act both as a delivery and waste removal system for the body. Nutrients, oxygen and hormones are delivered to every cell and waste products such as carbon dioxide are removed. Not only does the circulatory system keep our cells healthy, but it also keeps us alive. The heart constantly receives signals from the rest of the body regarding what it requires to pump the correct supply wherever it needs. While sleeping, the body sends electrical signals to the heart that tell it to slow down. When participating in heavy exercise, the heart receives the message to pump harder to deliver extra oxygen to the muscles.

The human Respiratory System is a series of organs responsible for taking in oxygen and expelling carbon dioxide. Primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body. Blood then collects carbon dioxide and other waste products and transports them back to the lungs, where they’re pumped out of the body when we exhale.

The collection of glands that produce hormones that regulate metabolism is the Endocrine System, along with growth and development, tissue function, sexual function, reproduction, sleep and mood among other things. Although the hormones circulate throughout the body, each type of hormone is targeted toward certain organs and tissues. A gland selects and removes materials from the blood, processes them and secretes the finished chemical product for use somewhere in the body. Interestingly, the endocrine system affects almost every organ and cell in the body.

Time To Digest It All

The Digestive System is made up of the gastrointestinal tract (GI tract) or digestive tract, the liver, pancreas and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth all the way to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.

The Immune & Lymphatic System, are two closely related organ systems that share several organs and physiological functions. Our immune system is the body’s defense system against infectious pathogenic viruses, bacteria and fungi. Our immune system works to keep these harmful agents out of the body and attacks those that manage to enter. The lymphatic system is a system of capillaries, vessels, nodes and other organs that transport a fluid called lymph from the tissues as it returns to the bloodstream. Lymphatic tissue of these organs filters and cleans the lymph of any debris, abnormal cells, or pathogens.

The Urinary System, also known as the renal system or urinary tract consists of the kidneys, ureters (small tubes), bladder and the urethra. The purpose of the urinary system is to discard waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites and also regulate blood pH. The urinary tract is the body’s drainage system for the eventual removal of urine.

Last but not least we have the Reproductive System, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. Unlike most organ systems, the sexes of differentiated species often have significant differences. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring.


It is quite overwhelming when you realize just how complex the human body is. There are so many processes going on simultaneously without you even knowing it. We will be looking at the human body in more detail moving forward. This is in the thinking that if we understand ourselves better, it will give us better understanding and increase our chances of maintaining and staying healthier for longer. While a number of processes are out of our control, we can help the others with the way we choose to eat, drink and exercise. If this has been helpful to you, please let me know below. I know it’s not the easiest of reads, but hopefully it has given you a better understanding of the human body and its systems.

  1. Hi, You really know about your anatomy Of The Human Body, I like reading your post thank’s for sharing

    1. Hi Lyne,

      Thanks for your kind words regarding this post. I know its not the usual easy read as other posts. I just wanted to raise awareness as to how we are all put together and how we work.

  2. Nice post, your really know what you’re talking about. I learned a lot and loved it!

    Keep it up! 🙂

  3. Hi Lee

    I am constantly in awe of our bodies. They have to be the ultimate miracle.

    Where I work we are taking people’s temperatures on arrival and I had been worried that some people might be over our maximum allowed of 37.5 – especially women of a certain age having hot flushes! But no – they tend to have slightly lower temperatures. Our bodies know what to do to keep us right!

    I think you would like a book I got on Audible a while back called ‘The Wisdom of Your Cells’ by Bruce Lipton which is about how your beliefs actually control your biology. It is absolutely astonishing. We are complete machines which is why stress can cause devastating illnesses so keep thinking of health and vitality!.

    Looking forward to reading more of these great posts.



    1. Hi Jean,

      I too find the human body a masterpiece of cell, tissue and processes. I will be posting more articles like this one, so stay tuned.


      Speak soon

  4. I really enjoyed reading your article, it was a nice bit of revision on my anatomy and physiology that definitely needed a brush up!

    Our bodies are absolutely incredible and fascinating.

    Looking forward to your next post!

    1. Hi Amy,

      Hope you are well? This post was indeed for those who are looking for a quick catch up of the human systems in place. Really glad you enjoyed it and I hoped it helped you to remember some vital information.

      Take care.

  5. Hello,
    You have presented a great deal of important information in your article about the human anatomy. However, I do not see the correlation between what you have written and sports CBD.

    How does sports CBD affect each of the systems you discussed in your article? Does sports CBD enhance the respiratory system or digestive system or just the muscular system. If so, how?

    I do not see anything relating to that in this article. It appears that, the information you presented can easily be found by googling the human anatomy but again, I must say that it lacks the correlation with sports CBD.

    1. Hi Barbara,

      I hope you are well? Thank you for your comments. Everything on the site is there for people to learn ways to maintain a healthy lifestyle. Not everything has to relate to sport and or CBD.

      As this post suggests, it merely serves to enlighten people to the various systems in place for the human body, its relation to how it operates on a daily basis. The post is not meant to state the bodies reaction to sport or CBD, nor does it claim to.

      Apologies this wasn’t the reading material you were looking for. However, your comments have been taken on board for future reference.

      Please stop by again.

      Take care.

  6. Hello, a nice read about human anatomy and you explained well how different parts of the body works. How we eat affects the functions of our body as a whole as the food have impact on the cellular system…. and yes giving the body the right nutrients and minerals, is a great way of maintaining a healthy body.

    Thanks for sharing.

    1. Hi Evelyn,

      Thank you for your kind comments. The human body really is magnificent, we should take care of it as much as possible.

      I’ll be posting more about the human body, so if you enjoyed this check back in soon.

      Take care.

  7. I am new to your website so am finding a lot of information here.

    I am awed at how complex the human body is and how it functions so naturally. Since I have been very healthy all of my life, sometimes I forget about all of its complexities.

    Many of my friends talk a lot about getting older and wondering what their skin will look like when they get to be 65.

    You have addressed many things related to health and I am wondering how a person can keep their skin looking young as it ages – especially in the face and arms.

    1. Hi Jane,

      I hope you are well?

      This is the one billion pound question isnt it…how to keep skin looking young and healthy!

      One of the best things to keep skin healthy is to keep hydrated, drink plenty of water through the day. Also cut down on your caffeine intake as this can cause your skin to age.

      Its difficult to pinpoint exactly what you need as we all have different skin types. However, a good face cream with collagen ingredients will help too.

      Lets not forget your diet and genetics, as you know genetics are a huge contributing factor when it comes to aging.

      Take your time to eat as healthy as possible and regular exercise makes a huge difference too.

      Its kind of a health bundle to consider when thinking about yourself like that.

      If you check out my getting ready video, you will see the kind of things I get up to on a daily basis (its also a bit of a laugh).

      Please stop by again and let me know how the skin treatment is going and thank you for your kind words.

      All the best.
