Question
A hemoglobin molecule in the pulmonary vein would be carrying _____ oxygen molecules. a. 4 b. 2 c. 3 d. 1 Select the correct statement regarding blood cell formation. Before the seventh month of fetal development, yellow marrow is the main site of blood cell formation The main sites of blood cell production in adults are the spleen and the liver. Yellow marrow is the main site of leukocyte formation. Red marrow is the main site of blood cell formation throughout adult life. Living at high elevations will cause a person's hematocrit to: a. Decrease b. Stay the same c. increaseExplanation / Answer
1.Answer is a. 4
A hemoglobin molecule in the pulmonary vein would be carrying four oxygen molecules.
Pulmonary veins are the short, thin walled vein that carries the oxygen rich blood from the lungs to the heart.
Hemoglobin is a protein molecule that contains four subunits and can bind to four oxygen molecules. It is an iron containing oxygen that transports metalloprotein in the red blood cells.
2.Answer is 4. Red bone marrow is the main site of blood cell formation throughout adult life.
Bone marrow is of two types: red bone marrow and yellow bone marrow.
Red bone marrow is also called as myeloid tissue. It is red, soft and it mostly found in flat bones like pelvis, cranium, ribs, sternum, and vertebrae.
The process and the formation of red blood cells in the bone marrow is known as hematopoiesis.
3. Answer is c. increases.
Living at high elevations will cause a persons hematocrit to increase because at high elevations there will be less oxygen and kidneys will respond to hypoxia by secreting the erythropoietin hormone that stimulates the production of RBC production.
