What is homeostasis? Homeostasis is the ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. (McGraw-Hill) How does the body maintain homeostatic balance? Each organ system helps in some way to maintain homeostasis. However, the organ systems also work together to maintain a constant internal environment. There are seven organ systems (Integumentary, Musculoskeletal, Endocrine, Cardiovascular, Lymphatic, Respiratory, and Nervous) within the body. (McGraw-Hill) I will specifically be focusing on the structure of the integumentary system, and how it contributes to maintaining homeostasis. The skin is the largest organ in the body (12 to 15% of total body weight).…show more content…
(Marieb) Skin cells also synthesize melanin, and carotenes, which gives skin its color. The skin also assists in the synthesis of vitamin D. Children lacking sufficient amounts of vitamin D develop bone abnormalities known as rickets; a softening of bones due to deficiency or impaired metabolism of vitamin D, phosphorus or calcium, potentially leading to fractures and deformity. In conclusion the skin plays an important role in the maintenance of homeostasis. It is an important barrier to infections, and diseases. The skin also plays a part in the feedback loop that regulates body temperature and synthesizes important vitamins for our
