The transmitter spreads throughout the body
Functions of the Organ: Living organisms interact with their environment, including by absorbing materials from the environment and releasing materials. In single-celled creatures such as amoeba, for example, in simple multicellular organisms such as jellyfish, the process of exchanging cells with the environment takes place directly through cell membranes. In large multicellular organisms there is a need for devices that absorb materials from the environment and transport them to cells of the body. In addition, there is a need to mediate and coordinate the work (activity) of different devices.
The transport device in living organisms is responsible for transporting materials from the devices it absorbs into cells, for example: food from the digestive system and oxygen from the respiratory apparatus in humans and animals. The transport device is also responsible for the transfer of substances from cells to the devices they release (outside), as a secretion device in the human, and the transfer of substances that are formed in the cells to other cells in the body, and there work (activity) and help in mediation and coordination between the organs of the body , For example: hormones.
Therefore, the most important functions of the human transport device are:
- Transportation of the necessary needs: the transfer of oxygen from the respiratory system to all parts of the body and the removal of carbon dioxide from the cells towards the respiratory system and from it to the air.
- Transfer of food compounds absorbed by the human through the digestive system to all cells of the body and the removal of waste from the cells.
- Maintain the heat balance in the body.
- Protect the body from pathogens.
- Combines the nervous system and the internal secretion device (Hormonal system) in the mediation and coordination between the organs of the body.
