Explanation:
Capillaries: These tiny blood vessels have thin walls. Oxygen and nutrients from the blood can move through the walls and get into organs and tissues. The capillaries also take waste products away from your tissues. Capillaries are where oxygen and nutrients are exchanged for carbon dioxide and waste.
The pericardium acts as mechanical protection for the heart and big vessels, and lubrication to reduce friction between the heart and the surrounding structures.
The inner layer of the pericardium is attached to your heart muscle. There is a very small amount of fluid called pericardial fluid in the pericardial sac. This fluid helps to decrease friction between the pericardial layers. It also allows for smooth movement of the heart when it beats.
The ventricular septum is a thick structure comprised of discrete muscular bands that separates the left and right ventricles, and contributes to cardiac function.
function of chordae tendineae is to anchor the AV valves to ventricular papillary muscles and keep the AV valves in a closed position during ventricular systole to prevent the backflow of blood into the atria.
Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. ... The coronary arteries wrap around the outside of the heart. Small branches dive into the heart muscle to bring it blood.
