Answer:
Reticular and papillary layer of dermis.
Step-by-step explanation:
The blood is the main connective tissue present in the body. Each and every cell of the body requires blood for its activation and blood supplied cells remain healthy.
The bed sores hinders the blood supply because the superficial blood vessels are restricted. The papillary layer of the dermis and the reticular layer of the skin holds the compressed blood vessels in the case of the decubitus ulcers.
Thus, the answer is reticular and papillary layer of dermis.
