Yes, the cells are constantly being replaced. Cells are constantly splitting and multiplying. In a matter of seconds those cells will be replaced by new cells.
Materials removed from the kidneys are urea and water sugar!
The surface area can be increased so that it can absorb more materials. The microvilli protrude from the epithelial cells lining.
nutrients and other materials pass from the capillary blood into fluids surrounding the cells are waste products removed. Transport oxygen and the nutrients from cells that you need.
exocytosis
Excretion is the means by which waste material is removed from cells through the porous outer membrane.

Endocytosis

my son has had his testicle removed. they said that they seen adnormal cells. can you give some light on this ta yours Keith

Some of the proteins and lipids do control movement of materials into and out of the cell.
Yes, because of cell division
nutrients and other materials pass from the capillary blood into fluids surrounding the cells are waste products removed. Transport oxygen and the nutrients from cells that you need.
Lipids and proteins are the building materials of cells.
Some ways in which material may move in and out of cells are diffusion and also osmosis.
