Which tissue type is most susceptible to cancer and why?
Epithelial tissue is also the most common site for the development cancers. Carcinomas arise from epithelial tissue and account for as many as 90 percent of all human cancers.
Why are epithelial tissues more likely to become cancerous?
Since these tissues are often exposed to environmental insults such as chemicals and solar radiation and are often divide rapidly to replace lost cells, many cancers arise in epithelial tissues.
Which of the following types of tissues has the poorest capacity for repair or renewal?
Board Review – Cell Tissues
Question | Answer |

What is commonly known as fat? | adipose tissue |
What is commonly known as vascular tissue? | blood |
What type of muscle tissue is found in the walls of hollow organs? | smooth |
Of the 4 general types of tissue, which has the poorest capacity for repair or renewal? | nervous |
What is the most sensitive tissue or organ to radiation?
For example, since the blood forming cells were one of the most sensitive cells due to their rapid regeneration rate, the blood forming organs are one of the most sensitive organs to radiation. Muscle and nerve cells were relatively insensitive to radiation, and therefore, so are the muscles and the brain.
Which is the only organ in person’s body that Cannot develop cancer?
The heart, in contrast, doesnt get exposed to many carcinogens, just those in the blood. That, combined with the fact that the heart cells do not often replicate, is why you dont see much cancer of the heart muscle. Indeed, according to cancer statistics, it does not appear to occur at any measurable rate.
Why do 90 percent of all cancers arise from epithelial tissue?
Carcinoma Carcinomas, malignancies of epithelial tissue, account for 80 to 90 percent of all cancer cases since epithelial tissues are most abundantly found in the body from being present in the skin to the covering and lining of organs and internal passageways, such as the gastrointestinal tract.
Which of the four major types of tissues would carcinogens most influence?
Epithelial tissue and connective tissue would be the most influenced by carcinogens because their cells have the ability to divide. Muscle tissue and nervous tissue would be the least influenced by carcinogens because their cells do not divide.
Why do 90 of all cancers arise from epithelial tissue?
Which connective tissue has the fastest rate of repair?
Muscle has a rich blood supply, which is why it is the fastest healing tissue listed above. The circulatory system provides all tissues with nutrients and oxygen – both of which enable the tissue to heal.
