the sebaceous glands secrete an oily substance called sebum which helps to keep skin supple and intact
The main function of most types of epithelial tissue is to act as a protective barrier against physical, chemical, and biological agents. It also helps in absorption, secretion, and sensation in various organs and structures in the body.
Pigs actually don't sweat blood, they have glands that produce a red-colored secretion that acts as a sunscreen and inhibits bacterial growth on the skin. This secretion is often mistaken for blood, giving rise to the misconception that pigs sweat blood.
Pyloric ceca are finger-like projections found in the intestine of some animals, such as fish, amphibians, and insects. They increase the surface area of the intestine for absorption of nutrients and can also play a role in digestion and enzyme secretion.
Hyaluranic acid ------------------------------------- When a male ant is ready to mate, it secretes a special pheromone/smell that allows the female to follow it.
Camouflage is the process of blending into the background. It only works if the predator hunts by looking - animals who hunt by sound or smell are not fooled by camouflage! Many animals have color patterns which match the environment in which they live. If they freeze against this background, they blend in and are harder to see.
The function is to get rid of excess mucus.
Yes, but in mammals it is a minor function. (In salt water fish it is their major function.)
filtration, reabsorption and secretion
This type of epithelium is frequently found in glands, and the pancreas, where its function is secretion.
secretion of intrinsic factor
The function of epithelial tissue include: transportation of materials, protection of underlying tissues, absorption of water and nutrients and secretion of waste products.

No, it also modifies proteins and synthesizes the lysosomes for two additional tasks.
