Question

con base en el pasaje, ¿cuál es el propósito del sistema tegumentario en la regulación de la temperatura? o a. el sistema tegumentario evita que los órganos y tejidos corporales internos se sobrecalienten. o b. el sistema tegumentario ayuda a mantener la homeostasis mediante la transpiración. o c. el sistema tegumentario ayuda a enviar señales a otras células cuando la temperatura del cuerpo es muy alta. o d. el sistema tegumentario ayuda a que el agua circule hacia el exterior del cuerpo mediante la transpiración.

Explanation:

The integumentary system (skin, hair, nails, glands) plays a crucial role in temperature regulation. Homeostasis is the body's ability to maintain a stable internal environment. Sweating (transpiration) is a key mechanism of the integumentary system for cooling the body. When the body overheats, sweat glands produce sweat. As sweat evaporates from the skin's surface, it dissipates heat, helping to lower body temperature and maintain homeostasis.

• Option A only mentions preventing overheating of internal organs but doesn't highlight the homeostatic aspect which is central to the system's role in temperature regulation.
• Option C is incorrect as the integumentary system's main role in temperature regulation is not about sending signals (that's more of a nervous system function in this context).
• Option D only focuses on water circulation outward (sweat production) but doesn't connect it to the broader concept of maintaining homeostasis which is the overarching purpose.

Answer:

B. El sistema tegumentario ayuda a mantener la homeostasis mediante la transpiración.
