8. Thermoregulation is the process the body uses in order to keep the body at a regular temperature‚ which is about 37 degrees Celsius. 9. The hypothalamus contains body temperature sensors. 10. a. Two mechanisms the body uses to cool are dilating blood vessels and skin and making sweat glands produce more cooling sweat. b. Two mechanisms the body uses to heat itself are constricting blood vessels and skin and making muscles shiver to produce heat. 11. a. The stimulus is the raised body heat

Hypothalamus The hypothalamus may be very small‚ but it plays a very important role. The hypothalamus is about the size of a pearl‚ and it weighs about four grams in a brain that weighs on average about 1‚400 grams. It directs so many important functions for the body some examples of what it controls are Autonomic function control ‚ endocrine function control‚ Homeostasis‚ motor function control‚ food and water intake‚ body temperature‚ and the release of 8 major hormones. The hypothalamus

Australian ectotherms and endotherms A- TYPES OF TEMPERATURE REGULATION 1- The cat‚ human and platypus could be described as true endotherms‚ as they all maintain a relatively constant internal body temperature that is independent of the external temperature. As the environmental temperature rises from 5C to 40C‚ the humans body temperature remains constant‚ the cat’s and the platypus’ increases by around 3▫C. 2- The lizard and echidna are ectotherms as their body temperature fluctuates according

"Ergonomics" is the discipline that examines the capabilities and limitations of people. The term ergonomics is based on the two Greek word "ergon" and "nomos"‚ which together mean "the laws of work". In terms of design‚ the focus of ergonomics is man; and it aims to design appliances‚ technical system and tasks in a way to improve human safety‚ health‚ comfort and performance. Also‚ it makes products easy to be used. In the following paragraphs‚ I will discuss a number of factors including: the

Molly Curtis A&P 1 Case Study1 Marian suffered from a heat stroke causing her body to experience hyperthermia. Marian body went through the process of homeostasis from experiencing hyperthermia. “Homeostasis is a state of body equilibrium or stable internal environment of the body.”(Marieb 8) Homeostasis protects the body by allowing it to adapt to the environment. Marian homeostasis tried to cool the body but failed. Though Marian was lucky her daughter found her in time. When a heat
