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

BIOL 152-35 Professor Weller 14 February 2012 Effects of Temperature on Goldfish Respiration Introduction This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration‚ also known as aerobic metabolism‚ occurs when oxygen is taken

How fever works How does fever happen? Once endogenous pyrogens have been produced by the primary immune response‚ they must travel to the brain to actually induce fever. After their increased production by activated immune cells‚ cytokines such as IL-1‚ IL-6‚ and TNF are distributed throughout the body through the blood‚ as they are all soluble proteins. Now‚ then‚ these cytokines must have a target to signal and cause a reaction. PGE As it plays a central role in thermal regulation‚ it

Pre-warming patients to prevent hypothermia in recovery: A literature review Every day patients undergo surgery with general anesthesia for simple procedures like hernia repairs or breast biopsies. Loved ones are escorted into cold preoperative areas where nurses have them remove every stitch of their own clothing and replace them with a chilly‚ threadbare piece of fabric which ties together a handful of times and falls‚ for most‚ to the knees at best. The preoperative nurse then

Australian Ectotherms and Endotherms- temperature regulation Part A :Types of Temperature regulation 1. Write down the meaning of the terms endotherm and ectotherm. Consult a textbook if necessary. a. endotherm Endotherms are animals that can maintain a constant internal body temperature. For instance mammals and birds are true endotherms that can maintain a constant internal body temperature b. ectotherm Ectotherms are animals that are not able to regulate their body temperature or in simple
