The Cardiovascular System Worksheet -- KEY
1.
What is the protective membrane covering of the heart called? pericardium
2.
Which chambers of the heart receive blood from the veins? atria
3.
What chambers of the heart are known as pumping chambers? ventricles
4.
What is the name of the blood vessel that brings venous blood from the head, neck, and
arms to the right atrium? Superior Vena Cava
5.
What is the name of the blood vessel that brings venous blood from the abdomen and
legs into the right atrium? Inferior Vena Cava
6.
What is the name of the blood vessel that takes deoxygenated blood from the right
ventricle to the lungs? Pulmonary Artery
7.
What is the name of the blood vessels that take oxygenated blood from the lungs to the
left atrium? Pulmonary veins
8.
The largest artery in the body is the Aorta
9.
The valves are formed from the most inner heart layer, or the Endocardium
10.
The valve between the right atrium and the right ventricle is known as the tricuspid valve.
The valve between the left atrium and the left ventricle is known as the bicuspid or also
known as the mitral valve.
11.
The valves between the ventricles and blood vessels are known as the Semilunar valves.
12.
Complete flow of blood through the heart. Blood entering the right atrium
flows through the tricuspid valve and into the right ventricle . From there, the
deoxygenated blood flows past the pulmonary semilunar valve and in through the
pulmonary artery and then to the lungs. Oxygenated blood leaves the lungs through the
Pulmonary veins and enters the left atrium.
13.
What is the semilunar valve? 3- half-moon pockets that catch blood and balloon out to
close the opening.
14.
What is the pacemaker of the heart? SA Node
