Final answer:
Erythropoiesis leads to a decrease in cell size and an increase in hemoglobin concentration (d) Decrease, increase. Erythropoietin facilitates red blood cell production from the bone marrow and its misuse can increase blood viscosity, posing health risks.
Step-by-step explanation:
As erythropoiesis continues, the cells decrease in size, but increase in concentration of hemoglobin. The correct answer is d) Decrease, increase. During the process of erythropoiesis, erythroblast cells mature into erythrocytes, which involves a reduction in cell size and an accumulation of hemoglobin, the protein responsible for oxygen transport in the blood.
Erythropoietin is a hormone that plays a crucial role in the process of erythropoiesis. The true statement about erythropoietin is a) It facilitates the proliferation and differentiation of the erythrocyte lineage. Erythropoietin is produced by the kidneys and stimulates the production of red blood cells (erythrocytes) within the bone marrow.
The use of erythropoietin to enhance athletic performance can be potentially dangerous because a) Erythropoietin increases blood viscosity, which makes it difficult for blood to circulate within the body. Increased blood viscosity can lead to an increased risk of thrombotic events such as heart attack or stroke.
