Question 1: The integumentary system includes organs such as skin, nails and hair. Watch the following TED Talk video:
This video elaborates on how these organs work and discuss how different parts of the integumentary system work in conjunction with the nervous system to regulate body temperature.
Question 2: Calcium is important for muscle contraction, neural and bone health among others. That is why calcium homeostasis is important to maintain. You can learn more about calcium homeostasis by watching the following video: https://www.youtube.com/watch?v=tQVzZaV9yDY.
Discuss how bones are regarded as calcium reservoirs, yet normal calcium levels are maintained by the interaction between bones, hormones, kidneys and the intestines.
Question 3: In chapter 3 you learned about the structure of a "typical" cell. The structure of the skeletal muscle cell is a bit different in order to accommodate to its unique function and the need to be contractile. Using the following video:
compare and contrast the typical cell to the skeletal muscle fiber, and how the structure of the skeletal muscle accommodates its contractile function.
Question 4: Anatomy and Physiology is the study of structure and function. With this in mind, select one epithelial tissue site in the body, describe how the structure of your selected epithelial tissue determines its function.
