Question

What is the temperature of blood?
A. 110 F
B. 100 F
C. 101 F
D. None of the above

Answer 1

The temperature of blood refers to the temperature of the body, the blood travels throughout the body and is said to maintain the homeostasis of the body by maintaining a constant internal environment. When there are changes in the temperature then the body is thought to have some of the other types of infection.

Complete answer: The normal temperature of the body is what is known as the temperature of the blood.
Blood is a colloidal liquid inside of which many cells or corpuscles are present along with the blood plasma. The normal temperature of the body is said to be $37°C$ and so the normal temperature of the blood is also $37°C$ or around $99°F$.
The body has various mechanisms via which it maintains the internal body temperature and hence the internal homeostasis.

Additional information: A normal adult body temperature, when taken orally, can range from 97.6–99.6°F, though distinct sources may give slightly various figures.
In adults, the following temperatures describe that someone has a fever: at least $100.4°F$ ($38°C$) is a fever, above $103.1°F$ ($39.5°C$) is a high fever.

Hence, the correct option is (D), none of the above.

Note: Body temperature and temperature of blood both are the same thing.
The constant temperature of the human body is $37°C$ which is equal to around $99°F$ any change in this disturbs the homeostasis of the body.
