Your body is a wonderful thing. It is made up of different systems consisting of organs with their own special functions. Some organs are liver, kidney, heart. Even your skin is an organ!
Cardiovascular system
In the cardiovascular or circulatory system, there is one major task of pumping blood into the body. The main organ of the system is the heart, pumping blood through all the parts of the body through the arteries. Blood contains oxygen, hormones and nutrients necessary for cells to grow, work, and repair. Cells take in these products and release carbon dioxide and other waste, and blood is brought to the organs that remove the cleansing solution through the veins through the veins.
Muscle system
There are various kinds of muscles in the body. Skeletal muscles are attached to the bones of the body and contract and move. Smooth muscles align the digestive system and help to move food and water. Myocardium is in the heart. They pump blood through the heart to the lungs and other bodies.
SKELETAL SYSTEM
The skeletal system is made of bone, joints, cartilage, which is a flexible tissue that forms part of the body like the nose and ears. Cartilage also helps bone and joints work smoothly. There are four main functions on the bone of the body. First of all, they support the body, use the muscles to move in various ways, helping to carry weight. Second, it protects other organs of the body from injury. For example, your skull protects your brain and your ribs protect many of the soft internal organs. Third, the bone stores important minerals such as calcium and phosphorus and releases them to the bloodstream when needed by other organs of the body. Finally, bone produces blood cells.
IMMUNE SYSTEM
Diseases in the form of bacteria, viruses, toxins, microorganisms can attack your body. Your immune system will help you fight disease and maintain health in various ways. Lymph is a liquid produced by the lymph nodes of various parts of the body and is transported to the cells in the bloodstream to wash harmful bacteria and waste. The bone center called bone marrow is the place where red blood cells and white blood cells are made. Leukocytes are important because they produce antibodies that kill toxins, bacteria, viruses. The thymus located in the chest produces special cells that fight disease. The spleen filters foreign matter such as old erythrocytes and bacteria. Adenoid (behind the nose) and tonsils (pharynx) also capture and kill bacteria and viruses.
Endocrine system
The organs of this system are called glands. They produce hormones. This is a chemical that tells your organs through your bloodstream what to do. For this reason, hormones are often called body messengers. The endocrine system regulates mood, growth, physical development, sleep, blood pressure, metabolism. This is the process by which the body turns food into energy.
