The basic circulatory system of vertebrate animals, which are those with a backbone, consists of a heart, the blood and the arteries and system of blood vessels. The heart pumps the blood first to the arteries and then throughout the body via the system of blood vessels.Know More
The heart is a muscular pump organ with two upper chambers, called atria, where the blood enters. After passing through a valve, the blood then enters one of the two lower chambers, called ventricles. The muscles of the ventricle contract to send the blood out of the heart and into the arteries. About the size of a fist, the heart muscle is extraordinarily durable, pumping about 3 billion times throughout the average human lifespan.
The blood carries nutrients, oxygen, water and waste products to and from the cells and organs through the system of blood vessels that exist throughout the body, sometimes traveling thousands of miles. There are different types of blood vessels.
The circulatory system of a pig is much like that of a human, with a four-chambered heart and a system of arteries and veins that carry blood. All vertebrates use a similar system to transport and distribute oxygen molecules to the cells of the body.Full Answer >
The main organ in the circulatory system is the heart, according to Hillendale Health. The two other major parts of the circulatory system are the blood and the blood vessels.Full Answer >
The cardiovascular system is made of three systems that work together: the heart, the lungs, and the arteries, veins, coronary and portal vessels. All of these systems are responsible for the flow of blood, nutrients, oxygen and other gases, and hormones to and from cells, states Live Science.Full Answer >
A closed circulatory system is a system that transports blood throughout an organism's body using a system of blood vessels. The heart pumps blood rich in oxygen through arteries throughout the body. Blood filled with waste and deprived of oxygen returns to the heart through the veins.Full Answer >
