where dead RBC cells go after death

Question

Answer

the dead RBC goes to liver.

Answer

Where do dead RBC cells go after death?

Red blood cells (RBCs) play a crucial role in oxygen transport in the body. However, RBCs have a lifespan of approximately 120 days, after which they are removed from circulation. But where do these dead RBCs go after death?

1. Phagocytosis by macrophages

When RBCs reach the end of their lifespan, they become fragile and start to break down. The process of breaking down RBCs is called hemolysis. The broken-down products of hemoglobin are then engulfed and digested by macrophages, specialized cells that act as scavengers in the body. This process is known as phagocytosis.

2. Recycling of iron and other components

Much of the material from dead RBCs is recycled by the body. The iron from hemoglobin is reused to make new RBCs, while other components such as amino acids, lipids, and nucleic acids are also recycled.

3. Waste elimination

Some of the waste products of hemoglobin breakdown, such as bilirubin, are eliminated from the body through the liver and kidneys.

4. Diseases affecting RBC destruction

In some diseases, such as sickle cell anemia and thalassemia, the lifespan of RBCs is shortened, leading to anemia. In other diseases, such as hemolytic anemia, RBCs are destroyed at an abnormally high rate, leading to increased bilirubin levels and other complications.

Conclusion

Dead RBCs are removed from circulation and broken down by macrophages through phagocytosis. The components of RBCs, including iron, are recycled by the body, while waste products are eliminated through the liver and kidneys. Diseases affecting RBC destruction can lead to anemia and other complications.

Answer

they get and are removed from the system in the spleen. spleen is also known as the graveyard of Rbc. and the remain of components of Rbc such as iron are used in the formation of new Rbc and spleen is not in liver it is situated in the upper part of the stomach.

Answer

The heme constituent of hemoglobin are broken down into Fe3+ and biliverdin. The biliverdin is reduced to bilirubin, which is released into the plasma and recirculated to the liver bound to albumin. The iron is released into the plasma to be recirculated by a carrier protein called transferrin. Almost all erythrocytes are removed in this manner from the circulation before they are old enough to hemolyze. Hemolyzed hemoglobin is bound to a protein in plasma called haptoglobin which is excreted by the kidney.
