The term circulatory system refers to the set of tissues and organs responsible for carrying nutrients and oxygen to all cells of an organism and extracting the waste generated. The circulatory system is mainly made up of the heart, blood vessels and blood. Depending on the organism, this type of system can have different characteristics. Blood is driven by the heart and during its trajectory passes through the lungs to be oxygenated and thus serve as a means of combustion for the cells. Any problem evidenced in the circulatory system can lead to death as a result of its delicacy.
The heart is present in all animals and is responsible for pumping blood regularly so that it reaches all parts of the body. The heart is basically a muscle that acts involuntarily and pumps blood; this type of involuntary action is related to certain automatic processes that the nervous system provides to the body. The heart is present in the center of the chest of human beings with a slight inclination to the left. Circulatory System
Vessels are divided into veins, arteries and capillaries. In the first case, it transports carbon dioxide to the lungs for its expulsion; in the second, it transports oxygen from the lungs; and finally, the capillaries serve as a connection between the arteries and the veins. Thanks to this, blood can reach all parts, serving as a vehicle for various elements that must be transported. Circulatory System
In relation to blood, it is composed of red blood cells, white blood cells, platelets and blood plasma. In the case of red blood cells, these are responsible for transport; white blood cells serve as a defense against infection, and platelets are responsible for blood clotting after an injury. Finally, blood plasma constitutes the liquid part of the blood.
The circulatory system is one of the aspects that has drawn the most attention to health in recent years. In fact, the poor diet present in Western societies results in the production of obstructions in the vessels and the accumulation of fat that puts people’s lives at risk . It is because of this circumstance that it is recommended to take care of eating habits and regular physical exercise as a way to prevent certain difficulties that can be fatal.
