Describe Homeostasis a. Maintain a state of equilibrium Denition of Cachexia a. Weight loss Difference between benign and malignant tumor a.Benign- noncancerous. Encapsulated, apoptosis, does not spread b.Malignant- metastasis, spreads to other structures. Primary & Secondary Prevention (difference with example). a.Primary: do not have disease and you are trying to prevent it (vaccines) b.Secondary: disease prevention. Mammogram Function of Mitochondria. a.Energy Powerhouse of the cell b.Contains own dna and ribosomes Difference between Osmosis, & Diffusion. a.Osmosis: uid transfer from low solute concentration to high solute concentration. b.Diffusion: uid transfer from high solute concentration to low solute concentration. Causes of edema a. Excess uid in the interstitial space. Increased hydrostatic pressure, decrease in plasma protein. Isotonic Solution with examples. a.Same solute particles of the blood; equal solute concentrations, causes no uid shifts b.0.9% sodium chloride c.Ringer lactate Sensible and Insensible water loss a.Sensible: urinate, lose water, feces b.Insensible: sweat Extracellular Fluid Decit with examples a. Vomiting, diarrhea Dehydration signs and symptoms. a. Thirst, decreased urine output, tachycardia, decreased BP, skin tinting. Dry mucus membrane
