The Cardiovascular System Worksheet
The Cardiovascular System
1. What is the protective membrane covering of the heart called? : Pericardium
2. Which chambers of the heart receive blood from the veins? : Atriums
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? : 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 vessels that take 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. : Mitral Valve
11.The valves between the ventricles and blood vessels are known as the. : Atrioventricular 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 valve semilunar valve and into the Pulmonary Artery , and then into the lungs.
Oxygenated blood leaves the lungs through the Pulmonary Veins and enters the Left Atrium.
13.What is the semilunar valve? : The heart valve at the base of the aorta and the pulmonary artery
14.What is the pacemaker of the heart? : Sinoatrial Node
15.List and describe the heart’s cardiac conduction system.
- Pacemaker Impulse Generation
- AV Node Impulse Conduction
- AV Bundle Impulse Conduction
- Purkinje Fibers Impulse Conduction
16. a. What is systole? : the period of contraction that the ventricles undergo while pumping blood into the aorta and the pulmonary artery
b. What is diastole? : the period of relaxation that follows as the chambers refill with blood
17.If the patient has an elevated blood pressure we say they have. : Hypertension
18.What is the stroke volume? : The volume of blood pumped from the left ventricle per beat
19.What is cardiac output? : The flow rate of the heart's pumping output: the volume of blood being pumped by both ventricles of the heart
20. a. What vessel carries blood away from the heart? : Arteries
b. What vessel carries blood to the heart? : Veins
c. What vessel is responsible for gas and nutrient exchange within each of the body’s
Cells? : Capillaries
21.Describe each of the following vessels:
a. arteries-Large blood vessels that carry blood away from the heart to all regions of the body, Walls composed of three layers, Contain bright red, oxygen-rich blood called arterial blood
b. veins-Form a low-pressure collecting system, Return oxygen-poor blood to the heart, Vein walls are thinner and less elastic than those of arteries
c. capillaries : Smallest vessels in the body, Only one epithelial cell in thickness, Form networks of expanded vascular beds
22.What is a pulse? : Palpation of the heart beat
23.Identify the location of the following pulse points:
a. What pulse is felt on the upper surface of the foot? : Dorsalis Pedis
b. What pulse is felt in the antecubital space? : Brachial
c. What pulse is felt in the groin? : Femoral
d. What pulse is found in the neck? : Carotid
e. What pulse is found on the wrist side of the arm? : Radial
24.Answer the following questions about blood pressure.
a. What is the first measurement of blood pressure? : Systolic
b. What does it measure? : The heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries.
c. What is the second measurement of blood pressure? : Diastolic
d. What does it measure? : The heartbeat when the heart muscle relaxes and allows the chambers to fill with blood.
25. a. What circulation route takes deoxygenated blood to the lungs where it can pick up
Oxygen? : Pulmonary Circuit
b. What circulation route takes oxygenated blood through the body? : Systemic Circut
