Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the function of simple columnar tissue?
A
Protection
B
Sensory Perception
C
Excretion
D
Absorption and secretion
Explanation: 

Detailed explanation-1: -Secretion: Epithelial tissue in your glands (glandular epithelium) can secrete (release) enzymes, hormones and fluids. Absorption: The epithelial lining of your internal organs, such as your liver and lungs, can allow the absorption of certain substances.

Detailed explanation-2: -Simple columnar epithelial cells can specialize to secret mucus that coats and protects the surrounding surface from damage(INSERT LINK). Because the epithelium can be innervated, simple columnar epithelium is also specialized to provide sensory input. These cells are found in the cornea, inner ear, and nose.

Detailed explanation-3: -Non-ciliated simple columnar epithelium is made up of glandular goblet cells which secrete mucin to form mucus. The rest of the cell is made up of cytoplasm with membrane bound secretory granules which secrete the mucin, and are found towards the apical surface of the cell.

Detailed explanation-4: -Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
