Title: Homeostasis Date: 19th January 2010 Aim: To observe‚ draw and label the parts of a nephron. Apparatus: Slide of the transverse section of a kidney Pencil Paper Microscope Method: The slide of the transverse section of a kidney was mounted on the microscope and observed under high power. Drawings of the parts of the nephron were made. Calculations of Magnification: Loop of Henle One Ocular Division = 0.22 µm Size of Specimen = 2 ocular divisions Conversion of Ocular

Title: Ms. K Cell Membrane and Homeostasis Experiment Objective(s): The reason for this experiment is to see how starch and iodine affect each other and how a plastic bag works similar to a membrane in certain situations. Introduction: I know prior to doing this experiment that iodine mixed with starch creates a dark color and that most objects‚ organic and inorganic‚ naturally experience isotonic reactions. Hypothesis: I think that the potato will absorb more starch than the sweet potato and

AIDS (acquired immunodeficiency syndrome) is caused by HIV (human immunodeficiency virus). HIV is transmitted usually through unprotected sex with someone who is already infected‚ but it can also be transmitted through infected blood. The immune system is greatly affected by the disease. Once it enters the body‚ the virus recognizes a protein on helper T-cells‚ called CD4 (Cluster of Differentiation Antigen No. 4)‚ and it attaches onto that receptor to take over the CD4 cell. The result is a virus

Homeostasis Imbalances: Diabetes Jessica Garcia Human Anatomy & Physiology I Professor Garcia March 24th‚ 2014 Homeostasis Imbalances: Diabetes Homeostasis is regulation of every system and organ in the body. How does diabetes affect homeostasis? In homeostasis‚ if the blood glucose level begins to decline‚ the pancreas releases the hormone glucagon‚ which then stimulates cells to release glucose into the blood stream. Now when the

Negative feedback Essay Homeostasis of Animals and Plants Many animals‚ including humans‚ can regulate their body temperature through a process called negative feedback. The temperature within the body is regulated to be maintained within a certain range. Animals capable of this type of homeostasis are deemed homeotherms (1). Temperature is adjusted by receptors that detect temperature fluctuations called thermoreceptors‚ which are found in the hypothalamus-a portion of the brain. These receptors

The American physiologist Walter Cannon used the term Homeostasis to describe the body’s ability to maintain a constant stable internal environment despite the changes to the external surrounding1‚2. The body has a range of receptors these are used to constantly monitor the body’s internal conditions to keep them in physiological limits. To achieve this‚ every organ works together and thus the body works together as a whole. This requires body to communicate with the organs‚ this is established through

Unit 5 task 3 (P5 M2 D2) – explain the concept of homeostasis‚ discuss the probable homeostatic response to changes in the internal environment during exercise‚ how homeostatic mechanisms control temperature‚ breathing and heart rate and evaluate the importance of homeostasis in maintaining healthy functioning of the body. Homeostasis Homeostasis is the maintenance of a constant internal environment in organisms. It involves volume of blood and tissue fluid within restricted limits‚ it also maintains

Homeostasis and why it is an important process for survival The environment around us is continually changing and poses difficulties for the body to carry out its internal processes. Homeostasis is the maintenance of a constant internal environment within the body regardless of changes in either external or internal conditions. It allows a certain degree of independence from the environment. Regulating body temperature is one instance where homeostasis occurs (Thermoregulation). Some methods
