the heart and fetal circulation

heart

blood vessels

blood

major components of the cardiovascular system

transportation of nutrients/oxygen/hormones and remove waste

major function of cardiovascular system

pulmonary circuit

right side of the heart pumps blood to lungs then it goes to the left side of the body

systemic circuit

left side of heart pumps blood to the body, then it goes back to right side of the heart

right side

deoxygenated blood from body enters right side of hearft and gets pumped to lungs

left side

oxygenated blood from lungs enters left side of heart and gets pumped to body

right atrium

right ventricle

left atrium

left ventricle

chambers of the heart

veins

take blood towards heart

arteries

take blood away from heart

superior vena cavae

inferior vena cavae

pulmonary veins

veins; carry blood towards heart; dump blood into the atria

aorta

pulmonary artery/trunk

arteries; carry blood away from the ventricles

superior vena cavae

returns blood from thoracic wall, upper limb, head and neck

inferior vena cavae

returns blood from abodmen, pelvis, and lower limb

right atrium

receives deoxygenated blood from

1. superior vena cavae

2. inferior vena cavae

3. coronory sinus

right ventricle

discharges deoxygenated blood into the pulmonary circuit via the pulmonary trunk/arteries

left atrium

receives oxygenated blood from pulmonary veins

left ventricle

discharges oxygenated blood into the systemic circuit via the aorta

valves

prevent backflow of blood into heart chambers

atrioventricular valves

prevent backflow into atria; tricupsid and bicuspid valves

tricuspid valve

between right artium and ventricle

bicuspid valve

between left atrium and ventricle

semilunar valves

prevent backflow into ventricles

pulmonary semilunar valve

between right ventricle and pulmonary artery/trunk

aortic semilunar valve

between left ventricle and aorta
