Question
In a developed fetus, blood cells are formed by
Yolk sac, red bone marrow, mesenchyme
Adipocytes, lymph nodes, reticular cells
Liver, spleen, thymus
None of the above
............
Endolymph in the ear contains __________________, which is responsible for depolarizing the membrane of the receptor cells.
sodium
spinal fluid
calcium
potassium
..............
Waste products that come into the bile canaliculi are secreted from
Kupffer cells
Hepatocytes
Chief cells
Sinusoids
............
In red blood cell recycling, the non-iron portion of heme
Stimulates erythropoiesis
Is broken down into amino acids
Binds transferrin
Becomes a waste product
Explanation / Answer
1) The correct option is Liver, spleen, thymus
Blood cells are formed in the liver, spleen and thymus of the developed fetus.
2) The correct option is potassium.
Endolymph in the ear contains potassium, which is responsible for depolarizing the membrane of the receptor cells. The high potassium content of the endolymph is carried as the de-polarizing electric current in the hair cells.
3) The correct option is Hepatocytes .
Waste products that come into the bile canaliculi are secreted from hepatocytes.Bile canaliculus is a thin tube, which collects bile secreted by hepatocytes.
4) The correct option is becomes a waste product.
The non-iron portion of heme is degraded into the waste product biliverdin in red blood cell recycling.
