Superior: The lung is above the diaphragm; above is described as… Anterior: Toward the front (the belly surface); another word is ventral. Matching: regional Terms

Axillary: Armpit.
Patellar: Kneecap area.
Sternal: Breastbone area.
Antecubital: Front part of the elbow area.
Flank: Fleshy area along the side between the ribs and the hip bone. Oral: Pertaining to the mouth.

c. Answer the following questions about the Integumentary system.

1. Mention and explain extensively the major function of the Integumentary system. If it is uncomplicated for you answer this question as an essay (none less than 5 paragraphs.) The Integumentary System, consisting of the skin, hair and nails, act as a barrier to protect the body from the outside world. It also has several other functions in the body.   The word INTEGUMENT comes from a Latin word that means to cover.   The most important function of the integumentary system is protection.   This system serves as a barrier against infection and injury, helps to regulate and maintain body temperature, removes waste products from the body, and provides protection against the sun's ultraviolet radiation. The skin is a protective covering, also the largest organ in our body.   It is composed of an epidermis and a dermis separated by a basement membrane.   A subcutaneous layer, not part of the skin, lies beneath the dermis.   The skin houses several different types of glands such as...
