How the heart works
pulmonary semilunar valve
tricuspid valve
left atrium
right ventricle
left ventricle
mitral valve
aortic semilunar valve
left pulmonary veins
pulmonary artery right
pulmonary artery left
aorta
right atrium
inferior vena cava
right pulmonary veins
superior vena cava
The heart
It carries deoxygenated blood from the right side of the heart to the lungs.
From the aorta, blood flows to all the organs. Oxygenated blood leaves the left ventricle through the aorta.
PULMONARY ARTERY
PULMONARY ARTERY
AORTA
AORTA
It is bigger than the left ventricle.
It is smaller than the right ventricle.
LEFT VENTRICLE
LEFT VENTRICLE
RIGHT VENTRICLE
RIGHT VENTRICLE
It prevents blood from flowing backwards.
PAPILLARY MUSCLE
PAPILLARY MUSCLE
It prevents blood from flowing backwards.
It prevents blood from flowing backwards.
AORTIC SEMILUNAR VALVE
Aortic semilunar valve
Pulmonary semilunmar valve
PULMONARY SEMILUNAR VALVE
Deoxygenated blood enters the right atrium through the superior vena cava, then it passes to the right ventricle.
SUPERIOR VENA CAVA
SUPERIOR VENA CAVA
-It Venules farther from the heart; larger and thicker veins closer to the heart
-It has low pressure
-It carries deoxygenated blood towards the heart
VEINS
-It is large near the heart, with thinner and smaller arterioles farther from the heart.
-It has high pressure
-It carries oxygenated blood away from the heart
ARTERIES
-Capillary walls: one layer of flat cells, the capillary endothelium.It facilitates the exchange of gases, nutrients and wast between the blood and the cells.
-They are tiny
-They connect arterioles and venules
