stoma
Plant breathing hole
A stoma is a small opening or pore.
In biology, stomata (the Greek plural) are the tiny pores on plant leaves that allow gas exchange—carbon dioxide in, oxygen out.
In medicine, a stoma is a surgically created opening in the body, typically in the abdomen, that allows waste to exit when normal pathways are blocked or removed.
After her surgery, she learned to care for her colostomy stoma.
