Quiz on the Heart

What are the four chambers of the heart and their functions?

• The four chambers of the heart are the right, left, upper, and lower. Their functions include filtering blood and producing hormones.

• The four chambers of the heart are the pulmonary, aortic, tricuspid, and mitral. Their functions include storing blood and releasing it when needed.

• The four chambers of the heart are the atrium, ventricle, septum, and valve. Their functions include regulating blood pressure and producing red blood cells.

• The four chambers of the heart are the right atrium, right ventricle, left atrium, and left ventricle. Their functions include receiving blood from the body and pumping it to the lungs (right side), and receiving oxygenated blood from the lungs and pumping it to the body (left side).

What are the components of blood and their functions?

• Red blood cells, white blood cells, platelets, and serum; carrying carbon dioxide, producing energy, and regulating body temperature

• Plasma, platelets, leukocytes, and erythrocytes; producing antibodies, regulating pH, and maintaining body temperature

• Red blood cells, white blood cells, platelets, and plasma; carrying oxygen, fighting infections, blood clotting, and transporting nutrients and waste products

• Hemoglobin, plasma, lymphocytes, and fibrinogen; transporting hormones, storing fat, and regulating blood pressure
