Pathophysiology Exam 1: Immunity Objectives 1) Describe the cell functions of the Immune System: Lymphocytes- small white blood cells that are responsible for much of the work of the immune system. Three types: Natural Killer Cells-NK cells provide rapid responses to virally infected cells and respond to tumor formation. NK cells are unique bc they have the ability to recognize stressed cells in the absence of antibodies and MHC‚ allowing for a much faster immune reaction. Trigger phagocytes

This system eliminates pathogens by producing specific antibodies‚ which are effectors of humoral immunity; and the activation of T‐cells‚ ‐ which are effectors of cell‐mediated immunity. B. Abnormal Immune Responses INAPPROPRIATE responses can lead to tissue damage (e.g.‚ hypersensitivity) or reactivity against self antigens (e.g.‚ autoimmunity); CONVERSELY‚ impaired reactivity to appropriate targets (immunodeficiency) may occur and abrogate essential defense mechanisms.

PCP/Angel Dust (Phencyclidine) Classification: hallucinogenic MW: 243.394 g/mol pKa: 8.29 Chemical Formula: C_17 H_25 N IUPAC name: 1-(1-phenylcyclohexyl)piperidine Description Phencyclidine also known as PCP‚ is a hallucinogenic which is normally used as an veterinary anesthetic. PCP is similar to another hallucinogenic drug‚ Ketamine‚ based on their structure and effects on the person. PCP causes a dissociative state by inhibiting NMDA receptors (N-methyl-D-aspartate).

Immunisation protects people against harmful disease. It uses the body’s natural defence to build resistance to specific infections (Australia Government Department of Health‚ 2013). It was Edward Jenner who developed the first vaccine in 1976 against small pox. Centuries later the next vaccine was developed by Louis Pasteur. This was the anti-rabies vaccine (Lombard‚ Pastoret‚ & Moulin‚ 2007). It was these two men who gave hope to other scientist for the development and prevention of other infectious

One needs to set realistic goals within the given structure and parameters‚ for both career and results of the assessment depending on one’s natural aptitude and ability. Schools and the environment at home play a very important role in this. Hypersensitivity to a particular event in our lives (in this case examinations) is neither desirable nor appropriate. Being too anxious‚ concerned or worried is not a suitable state of mind for tackling examinations. One needs a quiet confidence‚ borne out of

Parasites that alter the behavior of the host Giardia lamblia – induce biochemical change in the host cells at the site of infection (duodenal epithelium) Parasites – have life cycles that often involve several hosts (survival
