The Heart
100

This cardiovascular component pumps blood throughout the body.

What is the heart?

100

These blood cells carry oxygen using hemoglobin.

What are red blood cells (erythrocytes)?

100

This is the process that stops bleeding after a blood vessel is damaged.

What is hemostasis?

100
These are the two major types of blood vessels.

What are arteries and veins?

100

The left side of the heart pumps this type of blood.

What is oxygenated blood?

200

These tube-like structures carry blood throughout the body.

What are blood vessels (arteries and veins)?

200

This liquid part of blood carries water, nutrients, hormones, proteins, and wastes.

What is plasma?

200

All blood types can receive this type of blood, which lacks all possible antigens.

What is O negative (O-)?

200

These blood vessels carry blood back toward the heart.

What are veins?

200

This test records the electrical activity of the heart and can help detect heart problems.

What is an EKG?

300

This cardiovascular component transports oxygen, nutrients, wastes, hormones, and immune cells.

What is blood?

300

These cell fragments help with blood clotting.

What are platelets (thrombocytes)?

300

This third step of hemostasis forms fibrin threads that strengthen the clot.

What is coagulation (blood clotting)?

300

These blood vessels carry deoxygenated blood from the heart to the lungs.

What are the pulmonary arteries?

300

This is the most muscular chamber of the heart and helps to pump blood from the heart to the rest of the body.

What is the left ventricle?

400

The cardiovascular system is essential because cells need oxygen and nutrients and must remove this gaseous waste product.

What is carbon dioxide?
400

These leukocytes include T cells and B cells.

What are lymphocytes?

400

These immune proteins can attack blood cells with unfamiliar antigens.

What are antibodies?

400

This is the largest artery in your body! It carries oxygenated blood from the left ventricle to the rest of the body.

What is the aorta?

400

This is the first structure in the heart’s conduction system and is often called the natural pacemaker.

What is the sinoatrial (SA) node?

500

The cardiovascular system works with many other body systems to keep you alive. Name one of those systems and briefly explain your answer.

Many possible answers! Ex. the respiratory system: lungs add essential oxygen + remove toxic carbon dioxide from blood

500

This leukocyte uses enzymes to digest parasitic worms.

What are eosinophils?

500

During the second step of hemostasis, this protein helps bind platelets to exposed collagen fibers in order to form a platelet plug.

What is von Willebrand factor?

500

What is missing?
Superior/Inferior Venae Cavae → Right Atrium → __________ → Right Ventricle → Pulmonary Valve → Pulmonary Arteries → Lungs

What is the tricuspid valve?
500

This term is used to describe a heartbeat that is abnormally fast, exceeding 100 beats per minute at rest.

What is tachycardia?
