Which of the following factors is the most important consideration in determining the status of the patient’s immune system? a) Age b) Gender c) Diet d) Environment Correct Response: b) Gender Explanation: There are differences in the immune system functions of men and women. For example‚ many autoimmune diseases have a higher incidence in females than in males‚ a phenomenon believed to be correlated with sex hormones. Autoimmune

There is likely a connection between stress and illness. Theories of the stress–illness link suggest that both acute and chronic stress can cause illness‚ and several studies found such a link. According to these theories‚ both kinds of stress can lead to changes in behavior and in physiology. Behavioral changes can be smoking and eating habits and physical activity. Physiological changes can be changes in sympathetic activation or hypothalamic pituitary adrenocorticoid activation‚ and immunological

time Acute Stress: a stressor appears and the body responds Stress is an adaptive response. There are two types of stress Chronic and Acute. The Acute response prepares the body for flight or fight response‚ where as Chronic depress the immune system and the liver releases energy. The Acute Stress Response – SAM (Sympathomedullary Pathway) Hypothalamus stimulates Sympathetic branch of ANS (Autonomic Nervous System) activates Adrenal Medulla releases Adrenaline or (noradrenaline) Gets

smallpox vaccine may have had an even more significant impact in terms of lives saved” said Dr. Baker the director of the medicine history. Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual’s immune system to develop adaptive immunity to a pathogen. Vaccines can prevent or ameliorate morbidity from infection. The effectiveness of vaccination has been widely studied and verified; for example‚ the influenza vaccine‚[1] the HPV vaccine‚[2] and the chicken pox

thefreedictionary.com/Epstein+barr+virus+mononucleosis #5.) What innate and acquired protective mechanisms should have been elicited in response to Blake’s viral infection? For the case of the EBV‚ a person’s innate immunity in a way preps for acquired (adaptive) immunity. Innate: Once the virus’ DNAs and proteins are made familiar to the body‚ this stimulates not only an interferon (elevated levels of INF-y specifically) response‚ but also NK cell activation. The interferon INF-y is made by activated T

PATHOGENS TO EVADE HOST ANTIBACTERIAL PEPTIDES AND PHAGOCYTES” The mammalian immune system has two major components; the innate and the adaptive immune system. The innate system is usually the first line of defence and it acts as a strong roadblock to invading bacterial pathogens through direct mechanisms such as inflammation‚ phagocytosis‚ complement system activation‚ antibacterial peptides and indirectly by activating adaptive response through antigen presentation (Radtke and O’Riordan‚ 2006). However

injected into the patient’s femoral vein‚ let me explain what our journey will entail. The first destination will be the lower lobe of the right lung. The patient’s immune system has been fighting an evil invasion of bacterium in the lung‚ and it is our assignment to document the battle. Once we have witnessed the patient’s immune system in action‚ we will head across the alveolar membrane and onward out the nose. Let get started on this incredible journey! We are now located in the right femoral

TAQ1 Definition of Pathogen and research into the main features of bacteria‚ protozoa‚ fungi and viruses. Pathogens‚ or infectious agents‚ are microorganisms that cause disease or illness to their host. There are divided into four groups; bacteria‚ protozoa‚ fungi and viruses. The term pathogen most often describes an organism that disrupts the normal physiology of a plant or animal. In identifying a pathogen it is important to determine the properties that ‘contribute to its infectious
