What are the different organ systems and what do they do? This is something that every person should know, it will make reading articles on your health much easier to understand and allow you to make an informed and educated decision about your health. You don’t need to be an expert on anatomy and physiology, but here are a few things that you may have forgotten about.
The circulatory system is also known as the cardiovascular system and it is compromised of the heart, blood vessels (arteries, arterioles, veins, etc.), and blood. This system is responsible for circulating and distributing things like oxygen, nutrients and hormones throughout your body.
The digestive system includes and sequential order, the esophagus, stomach, small and large intestines, rectum and anus. Your digestive system is responsible for producing enzymes that help you break down food.
The endocrine system controls your body’s functions through hormones which are produced in glands. Some of these glands are the pineal, hypothalamus, thymus, and thyroid.
The integumentary system protects your insides from injury, acts like a rain jacket, and aids in the regulation of body temperature. The skin, mucous membranes, hair, and nails are all members of the integumentary system.
The lymphatic system is responsible for storing and transporting white blood cells to and from the lymph nodes (carries lymph which is a fluid containing antibodies). The lymphatic system is comprised of lymph nodes, lymph vessels, the spleen, thymus, and tonsils (made of lymphoid tissue).
The muscular system allows you to move and live your life. This includes your skeletal muscles, the tendons which connect these muscles to your bones via ligaments forming joints. The muscle tissue has three types: skeletal, cardiac, and smooth. Your cardiac muscles (found in the heart) and smooth muscles (found in the walls of hollow organs such as your uterus and intestines) are under involuntary control. This means that the cardiac and smooth muscles don’t require any conscious effort.
The nervous system includes the spinal cord, nerves, and brain. Sensory receptors detect stimuli and then relay the message to the brain and there your brain acts as a control system. It makes quick decisions which protect you from possible threats.
The reproductive system includes ovaries, breasts, vagina, and in males the testes and penis. This system is responsible for human reproduction and it also produces hormones that affect your behavior and physical characteristics.
The respiratory system makes sure your body’s cells have oxygen and rids the body of carbon dioxide as the cells release it. Your nasal cavity, trachea, larynx, bronchi, and lungs all make up this system.
The skeletal system includes bones, ligaments, cartilage, and joints which all provide a framework for protection. It supports your body and its organs, and it allows for movement when it works with the muscula system.
The urinary system rids the body of nitrogen-containing wastes, maintains a balance of acid-base in the blood, and maintains water and electrolyte levels within the body.
