Glomerulus

Looks like

A tuft of leaky capillaries inside a cup, a million in each kidney.

What it does

The filter itself: it lets water and waste through and holds cells and protein back.

Keeping it well

Blood pressure and sugar control; protein or blood in the urine says this filter is damaged.
