Question
which is the right answer?
Part A O2 availability Increase Set point Decrease The figure shows the relation between the condition of a kidney and oxygen availability. Oxygen-sensitive cells in kidneys respond to a decline in oxygen availability by increasing erythropoietin production. Erythropoietin stimulates increased RBC production by stem cells in bone marrow. The increased number of RBCs returns oxygen availability to normal. in kidneys O2-sensitive cells in kidneys respond to a decline in O2 availability by increasing erythropoietin production Increased number of RBCs returns O2 availability to normal Erythropoietin stimulates increased RBC production by stem cells in bone marrow Based on information in the figure above, why do patients with kidney failure often become anemic? Excessive red blood cells are lost in the urine due to leaky filtration in the diseased kidneys. Kidney disease spreads to the bones and interferes with red blood cell production. The diseased kidneys destroy circulating red blood cells. The diseased kidneys do not secrete adequate erythropoietin.Explanation / Answer
The diseased kidneys do not secrete adequate erythropoietin.
The decreased erythropoietin levels will not stimulate enough RBC production in the bone marrow. This eventually leads to anaemia.
