Question

After 4 months, the spleen and liver cells ___, ___, and ___

a) Proliferate, shrink, regenerate
b) Atrophy, release stored iron, break down
c) Absorb, secrete, divide
d) Harden, transform, expand

Answer 1

The liver and spleen cells play a role in generating formed elements and removing old/damaged erythrocytes. They also store iron.

Step-by-step explanation:

Throughout adulthood, the liver and spleen maintain their ability to generate the formed elements through a process called extramedullary hematopoiesis. This process occurs outside the medullary cavity of adult bones. The liver and spleen play a role in the production of blood cells.

In addition, old and damaged erythrocytes are phagocytized by macrophages in the bone marrow, liver, and spleen.

The iron contained in the heme portion of hemoglobin may be stored in the liver or spleen, primarily in the form of ferritin or hemosiderin.
