Verified step by step guidance

Begin by understanding the role of the integumentary system, which includes skin, hair, nails, and in the case of birds, feathers. This system primarily serves as a protective barrier and plays a role in various physiological functions.

Consider the options provided: Thermoregulation, Digestion, Photosynthesis, and Respiration. Identify which of these functions are related to the integumentary system.

Feathers in birds serve multiple functions, including aiding in flight, providing camouflage, and importantly, thermoregulation. Thermoregulation refers to the process of maintaining an optimal body temperature despite external conditions.

Eliminate options that are not related to the integumentary system or the function of feathers. Digestion is related to the digestive system, Photosynthesis is a process in plants, and Respiration is primarily related to the respiratory system.

Conclude that thermoregulation is the function of feathers in the integumentary system, as they help birds maintain their body temperature by providing insulation and aiding in heat retention or dissipation.
