The integumentary system is made up of the skin and its accessory organs, including:

The integumentary system encompasses the skin and its associated structures, which play crucial roles in protecting the body, regulating temperature, and facilitating sensory perceptions. Oil glands, sweat glands, and sensory receptors are integral components of this system.

Oil glands, also known as sebaceous glands, secrete sebum that helps to moisturize and protect the skin. Sweat glands are involved in thermoregulation and waste excretion, helping to cool the body through perspiration. Sensory receptors, located in the skin, provide essential information about the surrounding environment, such as touch, temperature, and pain, thereby aiding in protective reflexes and interactions with the environment.

The other options, while they include important biological structures, do not fully represent the specific accessory organs directly connected to the integumentary system. For example, hair follicles are indeed part of the integumentary system, but they are not highlighted in the correct answer choice as accessory organs connected to skin function. Similarly, nerves and blood vessels, while associated with the skin, serve different functions, primarily related to signaling and circulation rather than directly to the supporting roles specific to the integumentary system. Cartilage and ligaments are associated primarily with the skeletal system and do not relate to the integument
