How does a cow get rid of waste?

Cattle get rid of waste in the form of feces, urine and sweat. Feces come from the "leftovers" of what a bovine ingested and digested, which pass from the stomach chambers through the intestines to the rectum. Urine is comprised of water, urea and toxins that were filtered by the kidneys from the blood and is stored in the bladder to be emptied via the urethra, which would exit from the vagina of the cow or heifer, or the penis of the bull or steer. Sweat for most bovines not of the subspecies B. p. indicus comes from the nose, and are essentially sweat glands that excrete contents filtered from the blood.
