There are four types of glands in the integumentary system: Sudoriferous glands, Sebaceous glands, Ceruminous glands, and Mammary glands. Sudoriferous glands are sweat producing glands. These are important to help maintain body temperature.

Sweat consists primarily of water and electrolytes. The primary electrolytes contained in sweat are sodium and chloride. Potassium, urea, lactate, amino acids, bicarbonate and calcium are also found.

* Cyanosis: Blueness of the skin in this condition occurs due to low levels of oxygen in the circulating blood. ...
* Erythema: refers to skin reddening and occurs due to increased blood flow in dilated blood vessels.
* Pallor: Loss of colour due to decreased blood flow.

Blood vessels have the ability to dilate and constrict to control body temperatre. ... When body temperature is too high, the capillaries dilate (vasodilation), which increases blood flow near the surface of the skin and so more heat is lost through radiation.

Injuries can be classified based on the nature and anatomic location of injury. By nature they may include simple or complex lacerations, avulsion injuries, amputations or associated paronychial injuries or fractures. A thorough assessment of the injury preferably under block or anaesthesia is essential to find the extent of damage so that repair or replacement of the injured structures can be made
