NUTR 222 Lecture Notes - Lecture 17: Basal Metabolic Rate, Adipose Tissue, Nitrogen Balance
Document Summary
Stress response: nonspecific response to a variety of different stressors. Draw on energy and protein stores to stop infection and build up tissue (for burns) Redness (since tissue is dilating, it comes closer to skin) Good to heal, but if it goes overboard it can cause tissue damage! Arteries/capillaries dilate and veinules (capillaries containing deoxygenated blo. Phagocytes sneak in through small gaps and destroy bacteria - good; normal in response. bacteria doesn"t go away quietly, becomes chronic inflammation: Phagocytes use hydrolytic enzymes and reactive forms of oxygen to kill b. Complete a surgery, etc. d blood) constrict - at al inflammatory kill bacteria. Body is using a lot to heal since tissues are dying. Can cause wasting and impair organ function - delay recovery. Hyperglycemia and insulin resistance -> increases risk of infection substantially. Overfeeding increases risk of refeeding syndrome (associated with hyperglyce. Calculate resting metabolic rate (basal metabolic rate) - the amount of energy completely at rest.
