stoma

The vast majority of patients choose the urostomy, in which surgeons create a stoma—a beefy red spout protruding from the belly—so that urine can flow from the kidneys, through an intestinal conduit, and out the body.

The other type of leaves had more surface holes, known as stomata.

When open, stomata take in carbon dioxide and exhale oxygen.

To conserve water, the plant will often close its pores, known as the stomata, to prevent evaporation.

One feature they looked at was the stomata, tiny openings in plant leaves that control how much carbon dioxide, water vapor, and oxygen enter and exit.

By change in shape of these cells the opening of the stoma is made larger or smaller.
