Question

The secretion of sweat is stimulated:

A) by high temperatures
B) when the air temperature drops
C) by hormones, especially male sex hormones
D) as a protective coating when one is swimming
E) both by high temperatures and by hormones, especially male hormones

Answer 1

Sweat secretion is stimulated by high temperatures to help cool the body and is also influenced by hormones, particularly male sex hormones. The process of sweating is an essential part of the body's thermoregulation mechanism. Option A is correct.

Step-by-step explanation:

The secretion of sweat is stimulated by multiple factors. Primarily, it is a response to high temperatures as the body works to cool itself through the process of evaporation. On hot, dry days, the evaporation of sweat from the skin effectively cools the body, whereas on humid days, the higher concentration of water in the atmosphere reduces the evaporation rate, making sweating a less effective means of cooling.

Additionally, sweat secretion is influenced by hormonal factors, particularly male sex hormones which can increase the production of sweat. Sweat glands, which produce sweat, are developed from epidermal projections into the dermis and are activated when the body becomes warm. The sudoriferous glands are classified as merocrine glands and are crucial in the body's process of thermoregulation through diaphoresis.
