Which body part is responsible for the manufacture of RBCs?
Answer
Correct Answer : d ) Bone Marrow
Explanation :Red Blood cells are made in the bone marrow and Spleen and Liver (in case of embryo). They generally live for 120 days. RBCs contain a protein called hemoglobin. Hemoglobin is responsible for carrying oxygen.
Erythropoiesis is the process through which new RBCs are produced. The process lasts for about 7 days.
Bone marrow is the soft, spongy tissue that contains many blood vessels and is found in the center of most bones.
There are two types of bone marrow: red and yellow.
Red bone marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets.
Yellow bone marrow is made mostly of fat and contains stem cells that can become cartilage, fat, or bone cells.
Hence, (d) is the correct answer.
