We explain what the circulatory system is and its main functions. In addition, the parts that compose it and their possible diseases.
The circulatory system allows the transfer of different nutrients.
The circulatory system or circulatory system is a complex internal transport mechanism that possesses to varying degrees the body of living beings, and allows the transfer of various nutrients, regulatory substances, chemical defenses and other fundamental substances throughout the body, as well as the collection of toxins, metabolic by-products and other waste materials for disposal.
In the case of the latter, haemolymph or other similar substances are transported; in the case of plants, sap.
The human body’s circulatory system includes a vast network of blood vessels known as capillaries, which are connected to a larger network of veins and arteries. At the center of it all, a muscle pump known as a heart.
When we cut or injure ourselves, the blood sprouts because some (usually minor) stretch of the network is violated.
Fortunately, the cells responsible for repairing tissue and stopping minor bleeding are also carried in the blood.
The circulatory system displaces chemicals such as white blood cells or hormones.
As has been said, the function of the circulatory system is key: keeping the blood moving to oxygenate the body and preserve the life of the tissues.
If any tissue were isolated from this vast blood network, any limb or organ, its cells would suffer from a lack of oxygen and die. This is called ischemia.
In the same way, this apparatus has the mission of communicating the whole body, allowing the displacement of chemical substances of diverse nature, such as hormones (to regulate the activity of the body), white blood cells (and other defensive cells), or the necessary nutrients to produce new cells and tissues (carbohydrates, proteins and lipids).
Even the medicines we take or the injections we receive use this transportation system to get where they’re needed.
Finally, circulating blood also passes through certain filters, such as the liver, where it is stripped of toxins, pollutants and substances produced by metabolism.
The circulatory system is both a nutrition channel and a waste collection channel.
The heart is a hollow muscular organ that weighs about 300 grams.
The circulatory system consists essentially of:
Arteriosclerosis is the accumulation of fat in the walls of the arteries.
The circulatory system can suffer from diseases such as:
