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.
The hypothalamus is involved in different daily activities like eating or drinking, in the control of the body's temperature and energy maintenance, and in the process of memorizing and in stress control. It also modulates the endocrine system through its connections with the pituitary gland.
