What are the different functions of the human body?
The human being consists of narrowly interconnected body systems that perform different functions of the human body. These functions of the human body include support, movement, replacement of gas, regulation, protection, elimination, transport, energy gain and continuity. Although the human body systems have separate roles, two of which have general control of other functions of the human body. These two systems, the nervous system and the endocrine system, are responsible for homeostasis or for maintenance of a steady state in the body.
in human anatomy muscle and skeletal systems, called the musculoskeletal system, cooperate in providing support and allow the body to move. Through alternative contraction and muscle relaxation, the movement of parts of the body is possible. Muscles also have automatic body movements such as heart rhythm. Meanwhile, an adult human skeleton is a collection of 206 bones that specialize in performances in a practical function. Bones keep posture and protect vital organs.
oxygen, toTerý is a gas necessary for human life, it is naturally present in the air that is accepted by the respiratory system. Inside the body, oxygen combines with substances that provide energy that come from food to provide fuel for cells. Carbon dioxide is a waste material produced by the breathing process. The main organs of the breathing are the lungs because they are responsible for the exchange of oxygen oxygen oxide, the most important function of the respiratory system.
nerve and endocrine systems generally integrate the function of the human body. With the brain and mix as its components, the nervous system receives and transmits signals through its nerve fiber network. This allows the body to respond to its external environment. Meanwhile, the endocrine system covers body processing through its glands that produce hormones. Hormones that act as messengers are released and transported by blood to affect the activity of the body.
Complicated defense system, which includes skin, mucosal membranes and lymphs, protects the body from the agents causing diseases. The membranes of the skin and mucous membranes or the first defensive line prevent bacteria from sufficient in the body. When they fail, the second line of defense or lymph performs their work by filtering and capturing bacteria. Meanwhile, most liquid waste is removed by the urinary system. The kidneys filter blood waste, and then these waste are mixed with excess water to form urine.
heart drives blood that transports nutrients and oxygen, gets rid of waste and protects the body from infection. The blood vessels and blood are attached to them as the ingredients of the circulatory system. Meanwhile, the long D Long tube called Igestion is responsible for the whole D, which allows the body to obtain nutrients and energy from food and remove solid waste materials. Human beings have a relatively short lifetime; Therefore, reproduction is required. However, the continuity of humanity is ensured with the action of the reproductive system.
