We explain what the circulatory system is and what its main functions are. In addition, its characteristics and how is its structure.
The circulatory system is a complex system of structures, organs, and blood vessels . It is responsible for transporting and feeding nutrients to and from cells and tissues throughout the body . In addition to transporting nutrients, the circulatory system transports oxygen throughout the body.
The circulatory system is made up of one of the body's main organs, the heart . This organ is a muscle that pumps blood to nourish the rest of the body. This pumping work can be done thanks to nerve impulses.
The heart is an organ that functions continuously from the moment of conception (when the embryo forms in the mother's womb) until the moment of death of the living being .
The circulatory system is the combination of the functioning of the cardiovascular system and the lymphatic system . The cardiovascular system is made up of the heart, blood vessels, and blood; and the lymphatic system transports lymph unidirectionally towards the heart.
It is not exclusive to human beings , or even to animals . On the contrary, plants also have a circulatory system that we will detail later.
The function of the circulatory system is to pump blood so that different nutrients and oxygen reach the interior of the cells of each organ.
The main organ of the circulatory system is the heart. This is located in the chest cavity . This is the organ responsible for generating blood to reach the different organs of the body.
The heart can have two pumps or four. The first is known as an open system. This one has two chambers, while the second one is known as a closed system and has four chambers.
Within the circulatory system are blood vessels. These might be:
Blood is the vehicle by which oxygen and nutrients travel through blood vessels. To put it another way, blood is like the flow of a river . This is red in color and contains:
The lymphatic system produces and transports lymph from the tissues to the blood vessels . The lymphatic system is essential for the body's immune system . Lymph is transported unidirectionally towards the heart.
Plants don't have blood. However, they are composed of a substance through which different plant nutrients circulate . It is through the xylem that plants capture nutrients from their roots. This is how the sap travels from the roots and is distributed throughout the plant.
On the other hand, there is the phloem, which is a type of tissue through which different substances pass for later storage.
This process begins when the plant takes in water from its roots . From there, the plant forms the crude sap that is transported through the xylem to the leaves. This sap is used to produce photosynthesis.
