Biology 30- Lesson 1 Assignment PART ONE: RESPONSE TO VIDEO 1. Homeostasis: The tendency of the body to maintain a state of equilibrium or a stable internal environment. Homeostasis occurs in the body when normal body functions or bodily fluids become unbalanced or over concentrated in the body. The video used thirst as an example of homeostasis (or a negative feedback loop). When the water in your body reaches only 1% of your body weight, the thirst centre of the hypothalamus is stimulated by a high concentration of salt in our blood. We respond to this by drinking more water or fluids. Our kidneys then conserve the water in order to regulate solute concentration in the blood. Other examples of homeostasis/ negative feedback loops in the human body are the regulation of body temperature, the balance of glucose concentration, and the balance of calcium levels in the body. 2. The nervous system is split into two main parts: the central nervous system and the peripheral nervous system. The central nervous system contains the brain and the spinal cord, whereas the peripheral nervous system contains the nerves and ganglia that are outside of the brain and the spinal cord.

    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.
