Research the structure and function of skin. How does a bruise form? What other herbs can be used to help bruises?
The skin is one of the largest organs in the body.
The skin consists of three layers: the epidermis and the dermis. Beneath the dermis lies the hypodermis or subcutaneous fatty tissue.
The skin has three main functions: protection, regulation and sensation. Wounding affects all the functions of the skin.
The skin is an organ of protection. The primary function of the skin is to act as a barrier. The skin provides protection from: mechanical impacts and pressure, variations in temperature, micro-organisms, radiation and chemicals.
The skin is an organ of regulation. The skin regulates several aspects of physiology, including: body temperature via sweat and hair, and changes in peripheral circulation and fluid balance via sweat. It also acts as a reservoir for the synthesis of Vitamin D.
The skin is an organ of sensation. The skin contains an extensive network of nerve cells that detect and relay changes in the environment. There are separate receptors for heat, cold, touch, and pain. Damage to these nerve cells is known as neuropathy, which results in a loss of sensation in the affected areas.
How does a bruise form?
what causes your skin to turn back and blue?
Basically, a bruise, or contusion, as it's referred to in the medical world, appears when blood vessels break due to a blow to the skin. Blood leaks out of these vessels resulting in a red, purple or black mark on your skin. Sometimes your skin can become raised when the blood from these vessels leaks into the surrounding tissues. In most healthy individuals, your body eventually will reabsorb the blood, and the bruise will disappear. In general, the harder your bump or blow, the larger your bruise will be, and arms and legs are the most typical areas for bruises.
