Which of the following chambers of the heart receives deoxygenated blood from the entire body?
Show answer
Answer: A. Right atrium
The right atrium is the chamber of the heart that receives deoxygenated blood returning from the systemic circulation, via the superior and inferior vena cava.
What is the primary function of the vena cavae?
Show answer
Answer: B. To carry deoxygenated blood to the heart
The superior and inferior vena cava are the largest veins in the body and they collect deoxygenated blood from all parts of the body and return it to the right atrium of the heart.
What is the process by which substances are exchanged between blood and body tissues at the capillary level?
Show answer
Answer: C. Diffusion and filtration
Exchange of gases (like oxygen and carbon dioxide), nutrients, and waste products occurs across the thin walls of capillaries primarily through diffusion and filtration, driven by pressure and concentration gradients.
The process of blood clotting is also known as:
Show answer
Answer: C. Hemostasis
Hemostasis is the physiological process that stops bleeding at the site of an injury, involving platelet aggregation and the coagulation cascade to form a blood clot.
The term 'stroke volume' refers to:
Show answer
Answer: B. The amount of blood pumped by the left ventricle with each beat
Stroke volume is the volume of blood ejected from the left ventricle during one systolic contraction. Cardiac output is the product of stroke volume and heart rate.
