The Rh factor refers to:
A protein found on red blood cells
Which blood vessel carries deoxygenated blood from the heart to the lungs?
Pulmonary Artery
What is the name of the innermost layer of the heart that lines the chambers and covers the valves?
Endocardium
What are two symptoms of congestive heart failure (CHF)?
Shortness of breath and swelling in the legs
What is a potential complication of untreated hypertension?
Stroke
What is the main role of thrombocytes (platelets)?
Form blood clots to prevent bleeding
What is the name of the blood vessel that returns blood from the lower body to the heart?
Which chamber of the heart pumps oxygenated blood to the rest of the body?
Left Ventricle
What does an embolism refer to?
A blockage caused by a blood clot that travels through the blood stream
What is the medical term for high blood pressure?
Hypertension
Which blood types can donate blood to a person with type AB blood?
A, AB, B, or O
Which type of blood vessel carries blood away from the heart?

The right side of the heart pumps blood to the lungs, while the left side pumps blood to the body.
True
Which of the following is a risk factor for developing coronary artery disease (CAD)?
Smoking
True or False:
Tachycardia refers to a slow heart rate, typically less than 60 beats per minute.
False
What is the primary function of erythrocytes (red blood cells)?
Carrying oxygen and carbon dioxide
True or False:
The pulmonary veins carry oxygenated blood from the lungs back to the heart.
True
What is the function of the myocardial layer of the heart?
Its primary function is to contract and pump blood through the heart's chambers and into the blood vessels.
A myocardial infarction (MI) is commonly known as:
Heart attack
What is the term for the blockage of blood flow to the brain, often resulting in stroke?
Cerebrovascular accident (CVA)
Which type of white blood cell is responsible for producing antibodies?
Lymphocytes
What is the role of capillaries in the circulatory system?
They are the site of nutrient, oxygen, and gas exchange between the blood and the body's tissues
The sinoatrial (SA) node is responsible for:
Triggering the heart’s electrical impulse
A heart murmur is often caused by:
A valve not fully closing
Explain the difference between arteries and veins.
Arteries carry oxygenated blood away from the heart to the body tissues. They have thick, muscular walls to withstand high pressure from the heart's pumping.
Veins carry deoxygenated blood back to the heart from the body. Veins have thinner walls and often contain valves to prevent the backflow of blood
