A. Blood pumped into a ventricle in one minute: This describes venous return but not cardiac output.
B. Blood pumped into the atria in one minute: Cardiac output measures blood leaving the heart, not entering the atria.
C. Blood pumped by each ventricle in one minute: Cardiac output is the amount of blood ejected by each ventricle in one minute. It is calculated by multiplying stroke volume (the amount of blood ejected per beat) by heart rate.
D. Blood pumped out of an atrium in one minute: This describes atrial function but is not related to the definition of cardiac output.
Correct Answer is D
Explanation
Trabeculae: These are thin connective tissue strands that extend from the capsule of the lymph node into the interior. They help to divide the lymph node into distinct compartments or regions, which include the cortex (outer area) and medulla (inner area). This compartmentalization is important for the organization and function of the lymph node, allowing it to efficiently filter lymph and facilitate the immune response.
