Abstract
The integumentary system is comprised of the skin and skin derivatives including hair, nails, glands and receptors. Skin, glands and receptors have many important functions that are described in this paper.
From the Paper
"The skins keeps the inside structures in and outside substances out (Introduction to Anatomy and Physiology). Its strength and pliability make it very tough to outside physical forces. Keratin is a protein in skin cells that makes skin water repellant thereby providing resistance to many chemicals. Acidic skin secretions also help resist chemical damage and prevent bacterial growth. And, the skin protects the body from ultraviolet radiation damage. Coloration cells in the skin are called melanocytes. Exposure to sunlight increases the production of the pigment melanin in the Epidermis (thin outer layer of skin), creating a suntan. This darkening of the skin helps shield the cell nucleus from ultraviolet damage. Sebum, secreted by the skin prevents our bodies from evaporating too much water through the skin and helps prevent dehydration."

Abstract
This paper examines elements of the integumentary system. The paper looks out how the system helps maintain homeostasis as well as first, second and third degree burns., why no cancers arise in the stratum corneum, and the effects of a reduced subcutaneous tissue layer in the newborn and the aged on temperature control.
From the Paper
"You go to the beach to swim on an extremely hot sunshiny afternoon Describe two ways in which your integumentary system acts to preserve homeostasis during your outing The integumentary system preserves homeostasis in the body by regulating temperature and water loss on a hot day The body temperature is kept stable by the production of sweat which cools the body as it evaporates on the skin's surface The sweat glands can release between one and two liters of water per hour The Integumentary System

Abstract
This paper provides an explanation of the evolutionary development of the circulatory, respiratory, digestive, sensory, and integumentary systems of phylum chordata. Comparisons between the systems various classes of phylum chordata are made, and the evolutionary advantages of the higher classes are highlighted. The paper is also accompanied with relevant diagrams and figures.

From the Paper
"One of the most fascinating developments made by the vertebrates was the heart. The complex and efficient four-chambered pumping mechanism possessed by mammals and birds evolved from what was only a muscular artery in protochordates. The heart itself is a specialized muscle responsible for circulating blood through the blood-vascular network. Marine protochordates possessed little more than a muscular region near the base of the aorta because, virtually anywhere on their bodies, they were capable of exchanging O2 and CO2 through their relatively thin skin. When scales and thicker skin emerged, however, this capability was lost, and respiration was localized in the pharyngeal region. An effective pumping device was required, and thus, the heart evolved."
