Nails are made up of keratin like hair. The blood supply for the fingernails and toenails is at the base or growth area. If the base of the nails is damaged then the entire nail will turn black and die and fall off. If the damage is not permanent a new nail will grow from the base. Fingernails take about 5 months to grow from base to fingertip, toenails take about 1 year to totally regrow.

How do the circulatory and urinary systems work together?
The urinary and circulatory systems work together by the cells in your body dumping the wastes into your blood. Then the arteries carry the cleaned blood throughout the body. Meanwhile, the veins are carrying the uncleaned blood to the heart and the kidneys. In the kidneys there are blood filters where the blood flows through them and it is cleaned. Then there is a tube that carries urine from the kidney to the bladder. The bladder stores urine until it is ready to leave the body.
