Heart Blood Flow and Airway Organization

Path Through Heart

1- blood enters R atrium thru tricuspid valve

2-goes to R ventricle (job-O2 to body)

3-blood to lungs via pulmonary artery

4-blood to L artery via pulmonary vein

5-blood to L ventricle (job-blood to rest of body) via mitral (bicuspid) valve

6-L ventricle partners with aorta to do job (blood to rest of body)

Right Atrium

deo2 blood to body

from veins

Right Ventricle

pumps deoxygenated blood to the lungs through the pulmonary artery

Left Atrium

O2 rich blood returns from lungs

via pulmonary veins

Left ventricle

receives O2 rich blood from L.A

pumps it to aorta→ rest of body

strongest chamber

creates b.p

tricuspid valve

blood movement RA to LV

miral (bicuspid) valve)

02 rich blood from LA to LV

pulmonary valve

lets blood leave RV to enter pulmonary artery

aortic valve

regulates blood flow from LV into aorta

pulmonary artery

carries deoxygenated blood from RV to lungs for O2

aorta

O2 rich blood from LV to rest of body

vena cava

carries deoxygenated blood to heart
