Question

At what temp does tissue damage begin?

a) Below 40°C
b) Above 45°C
c) Below 20°C
d) Above 50°C

Answer 1

Tissue damage from heat typically begins at temperatures above 45°C (113°F), which leads to denaturation of proteins and disruption of bodily functions.

Step-by-step explanation:

Tissue damage from heat begins at temperatures above normal body temperature. Typically, the threshold at which tissue damage can begin is around 45°C (113°F). Exceeding this temperature can lead to the denaturation of proteins, including enzymes, and thereby impede the body's metabolic processes. When tissue is exposed to heat, the rate of increase in temperature in the affected tissue will depend on the amount of heat absorbed and the duration of exposure. Prolonged exposure to temperatures even slightly lower can also cause tissue damage if the exposure is extended. Therefore, it is critical to control and manage exposure to extreme heat to prevent cell damage.
