into stress and the immune system (12 marks) Stress causes the release of ACTH from the pituitary gland which signals the adrenal glands to release anti-inflammatory hormones. This weakens the immune system leaving the body vulnerable to infection and illness. Raised levels of cortisol suppresses the TH1 immune response. Kiecolt-Glaser et al conducted a natural experiment into acute stress, the aim was to see if the stress of exams had an effect on the immune system. Blood samples were taken from

primary infection of the chickenpox, the virus goes dormant in the nerves and then the immune system stops responding to it. However, VZV can reactivate to cause herpes zoster to appear many years later (also known as shingles which has similar but mild symptoms to chickenpox) (Nagel and Gilden 2007). The immune system responses to the primary varicella-zoster virus by, first, using the innate immune system with the release antiviral cytokines and activation of the NK cells (Arvin 2008). In response

of the lymphatic system as it pertains to the osmotic balance of the blood, then define net filtration pressure and how it can be interpreted, and describe the different relationships between filtration and reabsorption along a capillary. A complete answer will discuss the movement of fluid across the capillary wall at different points along the entire length of a capillary as well the overall net effect. Be sure to explicitly state how the lymph system and cardiovascular system interact to produce

situation, this patient does not need to be quarantined, as we do not know if the antibodies present in his body are from a current infection or due to a vaccination. Measles and mumps antibodies are virus-specific proteins produced by the immune system in response to an infection by the measles or mumps virus, or in response to vaccination. There are two types of antibodies produced, IgM and IgG. The first type to appear in the blood after exposure or vaccination is IgM antibodies. Levels of IgM

PART I Introduction Von Bertalaffy (1956) defines a system as a complex of interacting elements. Rapaport defines a system as an entity which can maintain some organization in the face of change from within or without. Ryan defines a system as a set of objects or elements in interaction to achieve a specific goal. In 1936, it was first revealed by Ludwig Von Bertalanffy, a biologist. Just because he witnessed them striking parallel to each other he sensed the need for an approach to lead research
