Do we drop dead cells from our body? Are they invisible? Else what happens to the dead cells?

Answer 1

Yes, we do shed dead cells. They aren't invisible, just really really tiny so unless they're all clumped together, they can't be seen. Dandruff, scabs, dry skin are just some examples of dead cells all clumped together. Other dead cells in the body would either be "recycled" in the body for their nutrients or excreted through sweat, urine and poo.

Answer 2

Shedding of skin cells happens all the time. As the previous answer stated, the floor is full of them. So is the top of any appliance like fridge etc. Dust mites live off your dead skin cells, if you look at house dust under a microscope, you will see a lot of dead skin cells and a lot of dust mites.

Answer 3

The epithelium sheds continually. Skin is a constantly regenerating organ. It requires the finest microscope to visualize epithelial cells. When they accumulate they can be seen as dust such as those we clean off tabletops and bookshelves. Larger forms of dead cells are in the form of hair (keratinized skin derivative), scabs, dandruff, etc.

Answer 4

We are changing cells all the time. Next time you sweep the floor have a look at all that dust. You are sweeping half your body out of the door lol
