Answer:
One of the major systems in the human body is the circulatory system, which is made up of a fluid called blood, a set of conduits (arteries, veins, capillaries) and a driving pump that is the heart. The heart is a muscular structure that contracts regularly and keeps the blood in constant movement within the blood vessels. Blood contains hemoglobin-rich red blood cells that carry oxygen to all cells in the body.
Explanation:
The circulatory system is above all a transport system that facilitates the movement of different substances through the body, mainly oxygen and nutrients. The main components of the human cardiovascular system are the heart, blood and blood vessels. The heart is located in the center of the thorax, above the diaphragm, between the right and left lungs, its function is to pump blood to all corners of the body, to drive blood through the vessels throughout the body, the heart it contracts and relaxes rhythmically. Blood is the component of the circulatory system in charge of transporting the necessary nutrients for the body's tissues, it reaches all organs and tissues thanks to a complete network of conduits called blood vessels. The arteries carry blood leaving the heart and the veins that make the reverse journey and carry the blood that enters the heart.
