Q:

How is the heart supplied with oxygenated blood?

A:

Quick Answer

The heart draws oxygenated blood from the lungs and distributes it to the rest of the body using a system of arteries and veins. Small coronary arteries and the pulmonary veins provide oxygenated blood into the heart. The pulmonary artery then pumps deoxygenated blood to the lungs where it is resupplied with oxygen.

The heart is made up of two parts separated by the septum. Four chambers and four valves help control the way the blood flows into and out of the heart. Each chamber consists of a top part, or atrium, and a bottom part, or ventricle. The right atrium and the right ventricle pump blood into the lungs via the pulmonary artery. The blood picks up oxygen in the lungs and returns to the heart through the left atrium and left ventricle. The left atrium pumps blood through other parts of the heart and the rest of the body. The oxygenated blood circulates through the body. Deoxygenated blood from the body goes back to the right atrium where the process begins again.

The aorta and the coronary arteries play an important role in providing oxygenated blood to the rest of the heart. The coronary arteries help move oxygenated blood from the aorta to the heart. The aorta provides oxygenated blood from the left atrium and left ventricle to the rest of the body.

    What does the cardiovascular system do?

    A:

    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.

  • Q:

    How does the circulatory system work?

    A:

    The beginning of the blood's journey through the body happens when the heart relaxes between beats and the blood flows from the atria to the ventricles from where the blood is pushed into the large arteries and then on to the smaller arteries where it releases oxygen and nutrients. The blood, now low on oxygen, gets pushed into the veins and travels back to the heart. Once the blood goes back to the heart, it is oxygenated and the process begins again.

    What is the structure of the circulatory system?

    A:

    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.

    What is the direction of blood flow in a capillary?

    A:

    The blood in human body flows from the heart to the arteries which branch into arterioles and then smaller capillaries, which then merge to form venules that merge into larger veins that carry blood back to the heart. This process is called the circulatory system.
