The outer layer of the skin, the epidermis, consists mainly of cells called keratinocytes.
The leaves of a plant give off water vapor through tiny openings on their surface called stomata. Stomata help regulate the exchange of gases, such as oxygen and carbon dioxide, and the loss of water through transpiration.
They are called stomata, tiny holes that regulate the intake/output of gas, such as carbon dioxide and oxygen.
This structure is likely describing the renal papilla, which projects into the minor calyx in the kidney. The renal papilla is the tip of the renal pyramid containing the openings of the collecting ducts for urine drainage into the renal calyces and eventually the renal pelvis.
That hole is called a sweat pore. Use the link below to learn more.

they are called stomata and they are used to exchang gases for the plant. It has to be very wet.

Renal Papilla
Stomata. These are the openings through which stomatal transpiration as well as gas exchange takes place.
It is a stoma, plural is Stomata.
Pores are tiny openings between particles of rock or soil that can contain air or water. These pores allow for the movement of gases and liquids through the material.
Stomata
Tiny openings on plant leaves are called stomata. Stomata are responsible for gas exchange, allowing plants to take in carbon dioxide for photosynthesis and release oxygen and water vapor.
The tiny openings under leaves are called stomata. Stomata are small pores that allow for gas exchange, including the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor.
