Where do dead cells go?

Question

Like blood cells, when they die, what happens to them. I don't know of any human cells that eat human cells unless they are cancerous. Tell, me where do dead human cells go and how do they get there.

Answer 1

Human cells do eat human cells. In fact the process of cell-eating is called phagocytosis, and the eater is known as the phagocyte. Phagocytes are commonly referred to as white blood cells.

Dead cells can come in the form of many things. I classify them into 2 groups, externally and internally.

Firstly, skin shedding is the process in which our dead skin cells get away from our body. They are removed by bathing or scratching. Sometimes, they just drop off or get blown away by the wind. That's why, wherever you go, you are actually leaving bits and pieces of yourself everywhere. The body continuously gets rid of dead cells and scientists estimate that by 7 years, your body would have replaced all old cells into new ones. It can be said that you are a new you. Unfortunately, our brain cells do not die away and get replaced.....pity we don't get smarter.

Internal dead cells refer to the digestive track, in which the cells lining our alimentary canal drop of, and get carried away by the poop. Our poop mainly consists of dead cells that have attached themselves to it, undigested food (fiber) and bacteria. You see, pooping does not relieve you of a tummy ache. It helps cleanse your body.

Next, not all cells which are dead get disposed off. Some living cells, such as red blood cells gets broken down in the spleen. When they are broken down, the materials that made it can still be reused. For example, when RBCs are broken down, hemoglobin is released and further broken down into iron which is stored in the liver. Phagocytes play a part in the breaking down of such substances.

Answer 5

Most human cells go out through digestive system if they are internal, I think... and others just fly off the body (skin ones, for example). Dead cells accounts for most of the dust in a living area.

Answer 6

Actually there are human cells that eat dead cells, they are called macrophages. Dead red blood cells are removed in the spleen and are eaten by macrophages. Dead skin cells flake off and become dust. Epitheleal cells lining your digestive tract (from your mouth, esophagus, stomach, intestines etc) get digested along the way and the remnants end up in your poop.

Answer 7

Dead cells are "recycle" by your own body. Your hair grows naturally and that is due to dead cells of your body. Same goes for your natural nail growth

Answer 8

Blood cells are definitely filtered through the kidneys. Other cells that die, - I would guess are shriveled up and either stay there, or somehow get into the blood stream in a much smaller size to arrive at your kidneys.

Answer 9

Digetive tract gets rid of old cells and the kidneys excrete waste too. Our bodies also offload un-need CO2 through our respiratory tract.
Many millions of old epthilial cells are lost right off of our skin.

Answer 10

Tendons do not replce themselves after being fully established. Univ of Copenhagen found high levels of c14 in the tendons of kids from the 1960s all other body tissue was back to background level as is the earth now as a whole. It was the level of fallout from open nuke tests that caused this.
I study soft tissue fossils and have found tendons and other body parts in fine clays. mudfossils.com
