The organs and organs of the body are suitable for their functional functioning and provide the necessary needs - oxygen, food, carbon dioxide and waste - to the cells that build the body.
A section of the body organs that absorbs from the environment specific substances to the body, and releases (excreted) from the body into the environment other substances. Absorptive devices are a breathing apparatus that absorbs oxygen from the air and digestive system, which absorbs nutrients from the environment.
Absolute devices are the respirator (again) that releases carbon dioxide into the air and the excretory device that releases dissolved waste into the environment.
The transport device connects the absorbed devices and the devices on the one hand and between the cells on the other, and allows the transfer of the necessary needs to the cells and cells.
