Answer:
B
Solution:
Lymphocytes are the second-most abundant (20-25%) white blood cells (WBCs) and the most abundant agranulocytes in the blood. The most abundant WBCs are the neutrophils (60-65%), which are one of the granulocytes.
During a cardiac cycle, each ventricle pumps out approximately 70 mL of blood. This is called the stroke or beat volume. Each cardiac cycle has a duration of 0.8 seconds.
