Cardiovascular System Diana Calzada P.2
consists of the heart, blood vessels, and blood.
system has three main functions: Transport of nutrients, oxygen, and hormones to cells throughout the body and removal of metabolic waste
he mitral valve and tricuspid valve, which control blood flow from the atria to the ventricles.
aortic valve and pulmonary valve, which control blood flow out of the ventricles.
Layers of heart
Visceral layer of serous pericardium
Comprised of mesothelial cells and fat and connective tissues
Comprised of cardiomyocytes
Lines inner surface of heart chambers and valves
Comprised of a layer of endothelial cells, and a layer of subendo cardial connective tissue
Major Arteries and viens
The aorta is the large artery leaving the heart.
The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle.
The right coronary artery supplies blood mainly to the right side of the heart.
Differences between blood vessels
blood vessels form a tubular network throughout the body that allows blood to flow from the heart to every body cell and then back to the heart
Arteries carry blood away from the heart to other organs
Capillaries are tiny vessels that connect arterioles to venules
They have very thin walls which allow nutrients from the blood to pass into the body tissues
