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

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

Hyperthermia occurs at a temperature of 38 degrees or above. Hyperthermia occurs by the body absorbing or generating heat faster than it can be gotten rid of. In extreme cases it can cause the body’s enzymes and organ systems to fail. According to Homeostasis thermoregulation notes.pdf‚ Hypothermia occurs when the body temperature increases without an increase in the set point of the thermoregulatory centre of the hypothalamus. It occurs when thermoregulation fails and is unable to bring the body temperature

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

Introduction “Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal equilibrium when dealing with external changes” (2). “Homeostasis keeps the body’s environment under control and keeps the conditions right for cells to live and function. Without the right body conditions‚ certain processes (e.g. osmosis) and proteins (e.g. enzymes) will not function properly” (1). Thermoregulation is the process that allows the cyclists

Homeostasis‚ the tendency towards a relatively stable equilibrium between interdependent elements‚ especially as maintained by physiological processes. Any living creature needs to maintain a constant internal environment in order for their cells to work at optimal levels in order for them to survive and reproduce. Thermoregulation is a type of homeostasis that keeps the internal body temperature at a consistent level despite external stimuli. When the thermoreceptors in the skin/hypothalamus notice
