What does the Coronary Circulatory System do?

Answer 1

The cardiovascular system consists of the heart, blood vessels and blood. Its 3 main functions include:

1. Transport of oxygen and nutrients toward and wastes away from cells of our body

2. Immunological protection of our body from foreign organisms and substances

3. Maintenance of homeostasis including the regulation of body temperature, blood pressure, electrolytes and water balance.

Answer 2

All that the heart does is pump blood.

it is an organ that collects the deoxygenated blood from all the organs of the body via veins and sends it to lungs for purification, and supplies all organs of the body with oxygenated blood

Answer 3

The heart is the most impotant part of your body. Your heart starts pumping when you are just three months old in your mother uterus and stop working when you are dead.

The wall of the heart closes with a very high pressure, so that the blood goes with a very high speed, a valve closes so tightly so that the blood cannot come back again to the heart and then come back again after the circulation carrying de-oxygenated blood.

Or in other words, it's a PUMP.

Answer 4

Your heart is a pump. It's a muscular organ about the size of your fist and located slightly left of center in your chest.

Your heart is divided into the right and the left side. The division protects oxygen-rich blood from mixing with oxygen-poor blood.

Together, your heart and blood vessels comprise your cardiovascular system, which circulates blood and oxygen around your body. In fact:

• Your heart pumps about 5 quarts of blood every minute.
• It beats about 100,000 times in one day - that's about 35 million times in a year.

Oxygen-poor blood, "blue blood," returns to the heart after circulating through your body.

The right side of the heart, composed of the right atrium and ventricle, collects and pumps blood to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, making it turn red.

Oxygen-rich blood, "red blood," then enters the left side of the heart, composed of the left atrium and ventricle, and is pumped through the aorta to the body to supply tissues with oxygen.

Four valves within your heart keep your blood moving the right way.

The tricuspid, mitral, pulmonary and aortic valves work like gates on a fence. They open only one way and only when pushed on. Each valve opens and closes once per heartbeat - or about once every second.

A beating heart contracts and relaxes. Contraction is called systole, and relaxing is called diastole.

During systole, your ventricles contract, forcing blood into the vessels going to your lungs and body - much like ketchup being forced out of a squeeze bottle. The right ventricle contracts a little bit before the left ventricle does.

Your ventricles then relax during diastole and are filled with blood coming from the upper chambers, the left and right atria. Then the cycle starts over again.

Your heart is nourished by blood, too. Blood vessels called coronary arteries extend over the surface of your heart and branch into smaller capillaries. Here you can see just the network of blood vessels that feed your heart with oxygen-rich blood.

Your heart also has electrical wiring, which keeps it beating. Electrical impulses begin high in the right atrium and travel through specialized pathways to the ventricles, delivering the signal to pump.

The conduction system keeps your heart beating in a coordinated and normal rhythm, which in turn keeps blood circulating. The continuous exchange of oxygen-rich blood with oxygen-poor blood is what keeps you alive.

Answer 5

Yes, it is. It is responsible for the circulation of blood.

Answer 6

It pumps blood through blood vessels---Nova Net Answer

Answer 7

They supply the heart with the necessary oxygen it needs.

Answer 8

The heart provides the pumping action of the cardiovascular system. Its contractions provide the movement of blood throughout the body.
