Which of the following is true about epithelia?

Endothelium provides a slick surface lining all hollow cardiovascular organs.

In adult humans, most cancers are carcinomas or adenocarcinomas. These include cancers of the skin, lung, colon, breast, and prostate. Which of the four basic tissue types is involved, and why?

Epithelial tissue: it is exposed to the environment and is constantly dividing, both factors allowing more opportunity for damage and overcoming growth control mechanisms.

In adult humans, most cancers are carcinomas or adenocarcinomas. These include cancers of the skin, lung, colon, breast, and prostate. Which of the four basic tissue types is involved, and why?

Epithelium gives rise to most cancers. This is probably because epithelial cells divide more, leading to more opportunity for damage to growth control mechanisms, and because epithelia are more often in contact with environmental insults such as UV radiation and Carcinogens

Golgi bodies

Which of the following describes a holocrine gland?
