Heart

HEART

The heart is the most important organ of the circulatory system, which helps deliver blood to the body. It works with the lungs to add oxygen to blood and pump this freshly oxygenated blood through the blood vessels and around the body.

The heart also has an electrical system within. Electrical impulses within the heart help ensure that it beats with a consistent rhythm and proper rate.

The heart rate increases when the body needs more blood, such as during intense exercise. It decreases during times of rest.

The heart has four chambers. The two upper chambers are called atria, and the two lower chambers are called ventricles.

Blood flows into the right atrium from the veins of the heart and body (except the lungs), then it flows into the right ventricle. From there, it flows into the pulmonary artery, which has branches that reach the lungs. The lungs then oxygenate the blood.

This oxygenated blood travels from the lungs, through pulmonary veins that lead back and join together, to the left atrium, and then through the left ventricle. From there, the heart pumps the blood through an artery that branches to distribute blood to itself and other body parts (except the lungs).

The heart has four valves that ensure that blood flows in the right direction. The heart valves are:

  • The tricuspid valve
  • The pulmonary valve
  • The mitral valve
  • The aortic valve

The High-density Lipoprotein Cholesterol Blood Test is used along with other lipid tests to screen for unhealthy levels of lipids and to determine the risk of developing heart disease.

VLDL Cholesterol Blood Test

A VLDL Cholesterol Blood Test is useful in measuring the amount of very low-density lipoprotein (VLDL) in your blood.

Carnitine Total and Free Blood Test

This Carnitine Total and Free Blood Test measures your blood’s amount of a substance called carnitine. It compares the amount of carnitine that is usable or ” free ” to the total amount in your body.
