Excretory Organ
Function
Superior vena cava
Large Vein, carries deoxygenated blood from the
upper half of the body to the heart's right atrium.
Inferior vena cava
Large Vein, carries deoxygenated blood from the
lower half of the body to the heart’s right atrium.
Right upper chamber that receives deoxygenated blood
Right atrium
Right ventricle
Right lower chamber that pumps deoxygenated blood to lungs
pulmonary arteries
Carries blood from the heart to the lungs
pulmonary veins
Carries blood from the lungs to the heart
Left atrium
Left upper chamber that receives oxygenated blood
Left ventricle
Aorta
Left lower chamber that pumps oxygenated blood to the body
Main artery coming directly out of the left side of the heart
Valves
Structures in the heart that control the flow of blood (one-way)
Septum
Wall dividing the left and right sides of the heart

Left b/c it pumps a greater distance
Both sides are pumping simultaneously
Efficient design of heart- separates oxygen rich
and oxygen poor blood
Prevents backflow of blood

ACE
BDF
It supplies the heart muscle with oxygen and
nutrients for cellular respiration
Prevents backflow of blood
Left ventricle- pumps to entire body
No, pulmonary artery carries oxygen poor blood
Increase blood pressure
The oxygen poor blood and oxygen rich blood
would mix, circulating poor blood to body cells
and rich blood to lungs

Left pumps to the entire body
The blood in the heart is not being supplied to the
heart muscle itself, therefore requiring a coronary

Small bodies, less demands, easily
accomplished with diffusion
Pulmonary artery carries oxygen poor
