These cells also are covered in microvilli that increase their surface area and help re-absorb much of the good stuff from the filtrate and back into the blood.
Oh, other than waiting out the exponential growth period of the virulent organisms trooping through my microvilli into my circulatory system-hunky-dory.
These folds are lined with tiny hair-like villi and even tinier microvilli, which create a truly impressive surface area — large enough that, if it were unfolded, it would cover a tennis court.
This duct is full of tiny microvilli called stereocilia, which provide a huge surface area to help reabsorb some extra fluid, and help pass along nutrients to feed the idling sperm.
