The Pulmonary Arteries/Veins, Aorta, and Valves
Purpose:
This tutorial provides an exercise to reinforce the knowledge of the BIO
163 student on the pulmonary arteries and veins, aorta, vena cava, and
valves of the heart.
Objective:
The BIO 163 student will identify the pulmonary arteries and veins, aorta,
vena cava, and major valves of the heart, from memory, with 100%
accuracy.

The Pulmonary Arteries and Veins
The pulmonary artery is
responsible for carrying
deoxygenated blood to the
lungs from the heart.

The Pulmonary Arteries and Veins
The pulmonary artery divides into
two branches with each branch,
left and right, supplying its
respective lung with blood flow.

Below the pulmonary arteries are
the four left and right pulmonary
veins, which carry oxygenated
blood from the corresponding
lungs.

The Aorta, Vena Cava, and Valves
The pulmonary trunk is the base
of the pulmonary artery and
starts in the right ventricle.
C
C
Next
The Aorta, Vena Cava, and Valves
The primary artery of the human
body is the aorta. The ascending
aorta has its base at the aortic valve
opening and shares the pericardial
sheath with the pulmonary trunk as
it extends upward.

The Aorta, Vena Cava, and Valves
The superior vena cava is a vein that
transports deoxygenated blood to
the right atrium of the heart.
C
C
Previous
Next
The Aorta, Vena Cava, and Valves
The inferior vena cava performs the
same function but drains blood
from the lower part of the body.
C
C
Previous
Next
The Aorta, Vena Cava, and Valves
The tricuspid valve, also known as
the right atrioventricular valve,
connects the right ventricle and the
right atrium. It prevents the flow of
blood back into the right atrium.
C
C
Previous
Next
The Aorta, Vena Cava, and Valves
The mitral valve, or bicuspid valve,
serves a similar function in the left
side of the heart, connecting the
ventricle and atrium and preventing
blood from flowing back into the
left atrium.
C

Previous
Next
The Aorta, Vena Cava, and Valves
Found between the base of the
pulmonary artery and the right
ventricle, the semilunar pulmonary
valve opens when pressure builds in
the ventricle and closes as pressure
increases in the pulmonary artery.
C
C
Previous
Next
The Aorta, Vena Cava, and Valves
Between the aorta and the left
ventricle is the aortic semilunar
valve, which opens when pressure
increases in the left ventricle and
closes when pressure increases in
the aorta.
