Heart anatomy n Blood flow

pulmonary semilunar valves

prevents blood from Flying back into the heart after it is pumped to the lungs

Aortic semilunar valve

prevent blood from following back into the left ventricle after a pumped blood into the Aorta

Tricuspid valve

Controls blood flow between the right atrium and the right ventricle

Bicuspid valve

Control the blood between the left Atrium and the left ventricle

coronary arteries

blood vessels that Supply oxygen, rich blood to the heart muscle itself

Aorta

Largest artery, carries blood from the heart to the rest of the body

Pulmonary vein Carries blood from the lungs to the left side of the heart

Carries blood from the lungs to the left side of the heart

Pulmonary arteries

Carries blood from the right side of the heart to the lung

superior and inferior Vena Cava

The great venous trunks That returns the deoxygenated blood from the systematic circulation

interatrial septum

separates atria

Ventricles

pump blood into certain organ, Left to the organ system, right to the lungs

atria

A blood vessel that supplies, oxygen blood to muscles and tissues - Lower limbs

Endocardium

Inner lining of pumping chamber

Myocardium

Middle layer, thick muscle layer

Epicardium

outermost layer, serous membrane

Pericardium

Double layer membrane that surrounds and protects the heart

capillaries

Microscopic vessels were exchanges between cells and blood take place

venules

A small vein, collecting blood from the capillaries

Veins

receive blood from capillaries and carry it back to the heart

arterioles

Small branches of an artery leading into capillaries

Arteries

Carrying blood from heart and carry it into the capillaries

Systemic circulation

Carries oxygen rich blood from the heart to the body and returns oxygen poor blood back to the heart

Pulmonary Circulation

Oxygen poor blood from the heart to the lungs to get oxygen and return oxygen rich blood back to the heart
