Structure and Functions of a Human Body

I enjoy researching and learning more about the muscular and reproductive systems it is interesting to learn how they actually work together in our body to help us perform daily tasks in life. I especially enjoy the muscular system, I am a physical fit person, I enjoy daily exercise and keeping myself healthy and in shape therefore learning more about the muscular system is very interesting. The reproductive system is another wonderful system to study and learn about, it is a great part of human life. I find it amazing to learn about the structure and functions of these two body parts and how they actually work together to perform homeostasis.
We have so many muscles in our muscular system, too many to list. There are three main types of muscles. Cardiac muscles, skeletal muscles and smooth muscles, these particular muscle types are the main muscles of the muscular system and work together with other systems of the body to perform homeostasis. Muscles work together to provide the body with posture and other positions, they also have the ability to contract causing movements like walking and more subtle movements like smiling and breathing.
The cardiac muscle is an involuntary muscle of the heart; it is composed of two sides and four chambers, the left and right atria and the left and right ventricles. The atria are located at the top of the heart and receive blood from various parts of the body. The ventricles are located at the bottom of the heart and pump blood away from the heart. The right ventricles pumps deoxygenated blood to the lungs. The left ventricle pumps oxygenated blood to the rest of the body. The cardiac muscles have the ability to work and not get tired out. The muscle is controlled by the lower part of the brain called the medulla oblongata and the main function is to propel blood in to circulation.

The smooth muscle is an involuntary muscle that provides force that moves your bones. Smooth muscles work together with your conscious
