Blood and cardio review

Front

What are arteries?

Back

Arteries are blood vessels that carry blood away from the heart. They have thick muscular walls and are elastic, allowing them to withstand and regulate high blood pressure.

Front

What is hematopoiesis?

Back

Hematopoiesis is the process of blood cell formation that occurs in the bone marrow, stimulated by the hormone erythropoietin.

Front

What is the correct order of blood flow through the heart?

Back

The correct order is: Right Atrium (RA) → Right Ventricle (RV) → Left Atrium (LA) → Left Ventricle (LV).

Front

What is edema?

Back

Edema is the swelling of tissues caused by a drop in blood proteins, leading to fluid accumulation in the interstitial spaces.

Front

When is blood pressure highest in the systemic arteries?

Back

Blood pressure is greatest during ventricular systole, when the ventricles contract and pump blood into the arteries.

Front

What is the function of erythropoietin?

Back

Erythropoietin is a hormone produced by the kidneys that stimulates the production of red blood cells in the bone marrow.

Front

What are the main components of blood?

Back

The main components of blood are red blood cells, white blood cells, platelets, and plasma.

Front

What is the role of the heart valves?

Back

Heart valves ensure unidirectional blood flow through the heart chambers and prevent backflow during contraction.

Front

What is the difference between systole and diastole?

Back

Systole is the phase of the heartbeat when the heart muscle contracts and pumps blood, while diastole is the phase when the heart muscle relaxes and fills with blood.

Front

What is the significance of blood pressure?

Back

Blood pressure is a measure of the force exerted by circulating blood on the walls of blood vessels, crucial for ensuring adequate blood flow to organs.
