Question

Certain drugs, known as angiogenesis inhibitors, are effective anti-cancer drugs because they cut off the blood supply to tumors. Without blood supplying fresh oxygen and nutrients to the cancerous cells, the tumors cannot survive. Given this information, angiogenesis inhibitors will be least effective in treating tumors in

A- epithelial tissue
B- connective tissue
C- nerve tisse
D- nervous tissue

Answer 1

The answer is A: epithelial tissue lines the surface of blood vessels and organs so you can't really cut off tis blood supply 

Answer 2

(A). epithelial tissue.

Step-by-step explanation:

Angiogenesis inhibitors can be defined as anti-cancer drugs that inhibit growth and development of newly formed blood vessels around tumors.

These drugs are used in cancer treatment of various types of cancer. This is because, most of the cells receive nutrients and oxygen from blood supply and these drugs cut off the blood supply to tumorous cells.

However, angiogenesis inhibitors would be least effective for treatment of tumors in epithelial tissue as epithelial tissues do to not have blood vessels. These tissue receive nutrients and oxygen from tissue present beneath the epithelial cells.

Thus, the correct answer is option (A).
