Why do blood cells only live 120 days?

As they mature in the bone marrow, they also lose their nucleus and organelles in order to increase space for oxygen. Due to this loss of a nucleus and other organelles, blood cells cannot repair themselves when damaged; this limits their lifespan to about 120 days.

What blood cell lives 10 days?

Platelets (thrombocytes)

Platelets, or thrombocytes, are tiny blood cells that can only be seen under a microscope. They are made from the spongy center inside our bones known as bone marrow. Platelets typically live for about 8 to 10 days in our body.

What is the longest lived blood cell?

The longest living cells are 'Neurons'. Neurons are unique because of the fact that the mature cells oppose division to create new cells after development in the foetus. While other cells in the body die and regenerate, many neurons remain the same throughout a person's lifespan.

What happens to a blood cell after 120 days?

Red cells have an average life span of about 120 days after which they are cleared by- phagocytosis by reticuloendothelial macrophages due to accumulated changes during their life span. Approximately 5 million erythrocytes (the average number per μl) are removed from the circulation every second.

What's the rarest blood type? AB negative is the rarest of the eight main blood types - just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don't struggle to find donors with AB negative blood. However, some blood types are both rare and in demand.

Why is there white stuff in my blood?
