Question

Which of the following organs is known as the graveyard of RBC?
A) Kidney
B) Liver
C) Spleen
D) Pancreas

Answer 1

Red blood cells transport fresh oxygen all over the body. This is very important to your health. Hemoglobin is a protein in red blood cells. It's transporting oxygen. Red blood cells also expel carbon dioxide from your body and transport it to your lungs to exhale.
Bone marrow is the place where Red blood Cells are produced. They normally live for about 120 days, and then they die.

Complete answer:

Old red blood cells are recycled in the spleen, which is called the RBC Graveyard. RBCs are manually filtered in the red pulp part of the spleen, and the old RBCs are recycled after filtration.
The spleen is an organ that is present in all vertebrates. Similar to the form of a large lymph node, it functions mainly as a blood filter.
As part of the mononuclear phagocyte scheme, haemoglobin is metabolised from senescent erythrocytes. The globin portion of haemoglobin is degraded to its constituent amino acids, and the heme portion is metabolised to bilirubin, which is eliminated from the liver. The spleen synthesises antibodies in its white pulp and extracts antibody-coated bacteria and antibody-coated blood cells via the blood and lymph nodes.
The spleen is the core of operation of the mononuclear phagocyte system and can be considered similar to the large lymph node, since its absence often creates a predisposition to some infections. Old and weakened RBCs are killed in the spleen as weak or worn out RBCs are trapped by their nullification and slaughter. This is known as the RBCs Cemetery. As RBCs are set to rest in harmony.
The spleen plays an important role in the red blood cells (also referred to as erythrocytes) and the immune system. It replaces old red blood cells and keeps a blood supply that can be useful in the event of hemorrhagic shock, and also recycles iron.

Thus the correct answer is Option (c) Spleen.

Note: Iron-rich diets help you preserve healthy red blood cells. Vitamins are also required to build up healthy red blood cells. These include vitamins B-2, B-12 and B-3, which are present in foods such as eggs, whole grains and bananas. Folate is effective, too. It is found in fortified cereals, dried beans and lentils, orange juice and green leafy vegetables.
