1 1. What is Anatomy and Physiology? Anatomy is the study the structures of the body and how they are organized. However, physiology is the science that study the function of bodily parts and the body as a whole. 2. What would happen if homeostasis is not maintained in your body? Homeostasis is the body’s ability to maintain stable internal conditions needed for it to function properly. If homeostasis is compromised the body can suffer very adverse defects that prevent the body’s internal from functioning properly or at all. As a result, this could cause great harm to the organism including death. 3. What is the organ in the integumentary system? Explain one function of that organ? The integumentary system consists of the skin, nerves, hair, glands, and nails that wraps around the exterior of the body serving as a barrier protecting the body from external factors. The organ of the integumentary system is the skin. The skin is the large organ in the body. One critical function of the skin is to help maintain normal body temperature. The skin achieves this by producing sweat to cool body in high heat. The skin also uses its abundant blood vessels, by dilating and contracting them accordingly to maintain body temperature. When the body is too cold blood vessels in the skin constricts to retain heat, and dilates them when it’s hot thus allowing more heat loss. 4. Explain how the kidneys and the urinary bladder work together to maintain homeostasis. The Kidney filter the blood than remove the waste then produce urine. For example, if the levels of concentration of Ions get higher than normal the kidney increase the excretion to bring the ions to normal

2 levels. The kidney regulates the levels of hydrogen ion in the blood, by remove. When the blood pressure is too higher the kidney maintains homeostasis by reducing the levels of blood in the body. 5. What is the relationship between tissues, organs and systems? Tissues makes up the structure organs and these organs work together to form organ systems. For example, the tissue that forms the heart is cardiac muscular tissue. This type of tissue allows for the heart to contract and thus perform its main function of pumping blood throughout the body. Blood travels through tubes knowns as blood vessels. When they work together they form the circulatory system. 6. Provide an example where the shape of an organ allows it to perform its function? An organ known for its unique shape is the small intestines. Its tightly woven shape allows it more room to expand when needed during digestion. This is due to the tiny folds that can open and allow the surface area of the small intestine to increase during the digestion process. It’s shape also helps it to carefully digest food by processing each food substances individually and slowly due to its long tubular shape. The inner surface of the small intestine is comprised of long finger-like tensions as known as microvilli. Thanks

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
