Skin changes, rashes, and infections are problems associated with which system?

The integumentary system is responsible for the protection, regulation, and sensation of the body. It includes the skin, hair, nails, and associated glands. When discussing issues such as skin changes, rashes, and infections, it is the integumentary system that is directly affected, as these issues manifest primarily on the skin or within the structures of this system.

Conditions like dermatitis, infections, or changes in skin appearance can arise from various factors such as allergies, infections, or even systemic diseases impacting the skin. Therefore, when considering the presented options, the integumentary system is the most relevant choice, as it encompasses all these problems directly related to skin health.

In contrast, the digestive system focuses on the processing of food and absorption of nutrients; cardiovascular health pertains to the circulatory system, involving the heart and blood vessels; and the auditory system relates to hearing and balance function. None of these systems are primarily responsible for skin-related issues.
