Doctors often break down low blood pressure (hypotension) into categories, depending on the causes and other factors. Some types of low blood pressure include: Low blood pressure on standing up (orthostatic, or postural, hypotension). This is a sudden drop in blood pressure when you stand up from a sitting position or after lying down.
The dermis is the middle layer of skin. It is a diverse combination of blood vessels, nerves, hair follicles and sebaceous (or oil) glands. The proteins collagen and elastin are found in the dermis. They provide support and elasticity to the skin. The sun's rays can break down these proteins and, eventually, the skin begins to wrinkle and sag.
Middle Layer of Skin-Dermis. The dermis is the hub of all operations in the skin where a lot of action takes place. The dermis is tucked away between the epidermis and hypodermis. It is the layer that holds all the blood vessels, nerves, hair follicles, collagen and sweat glands.
