Final answer:
The dermis contains blood vessels, lymphatics, and nerve fibers (D. A, B, and C), making it a critical component for communication between the skin and other organ systems.
Step-by-step explanation:
From the options provided, the one that identifies what the dermis contains to communicate with other organ systems is D. A, B, and C. The dermis, which is the core layer of the integumentary system, is rich in various structures that enable communication with the body's systems. These include blood vessels, lymphatic vessels (lymphatics), and nerve fibers. By containing these elements, the dermis plays a crucial role in facilitating nutrient distribution, waste removal, sensory reception, and immune responses.
The inner layer of skin, the dermis, is composed mainly of connective tissues and houses important structures such as blood vessels, which provide nutrients to the skin cells and help in thermoregulation, lymphatic vessels, which are part of the immune system, and nerve fibers, which make the skin a sensory organ capable of detecting touch, pressure, heat, cold, and pain. Additionally, the dermis contains hair follicles, and various glands, including sweat and sebaceous glands, contributing to skin's multifunctionality.
