Describes factors that disrupt homeostasis and how disruptions affect wellbeing.(ex) Fluid and electrolyte shifts can cause n/v or dysrhythmias.Explain RAASRenin-angiotensin-aldosterone system

• Reduce blood flow causes kidneys to release renin

> produce angiotensin I > converts angiotensin I to angiotensin II > vasoconstriction > release aldosterone > kidneys conserve sodium and water > Result less water lost in urine and blood pressure maintained.DKAincreased anion gap, decreased HCO3 How do kidneys compensate for alkalosisretain H and excrete HCO3 Untreated acidosis leads to an increase in which electrolyte?Potassium West Nile VirusTransmitted through the bite of an infected mosquito.

Basal cell carcinoma

• Squamous cell carcinoma
• Melanoma

basal cell carcinomaMost common and least severe type of skin cancer; often characterized by light or pearly nodules. Rarely metastasize, most common on face due to sun exposure squamous cell carcinomaType of skin cancer more serious than basal cell carcinoma; often characterized by scaly red crusted papules or firm nodules.MelanomaThe most serious form of skin cancer, caucasian males at highest risk, usually black or brown lesion consequences when integumentary system is disrupted impaired immunity types of burnsSuperficial (1st degree) - red/painful Partial-thickness (2nd degree) -wet/pink/painful Full-thickness (3rd degree) -white/swollen/no pain
