Patho Final Review - first part (1)

Document Content and Description Below

Patho Final Review: Tissue hypoxia (not enough oxygen): a condition known as shock -when the tissue isn’t getting oxygen your body can’t make ATP this is also known as anaerobic metabolism. ... Cell membrane: is a made up of lipids and protein and is hydrophilic; inside is hydrophobic and tends to repel water... when water gets through here by a transport mechanism: which are known as 1. Passive (happen regardless) -osmosis happens in passive this is when: water moves from higher grade of concentration to a lower grade. Whatever the salt level is sometimes is going to determine how much water movement will be. QUESTION: if I have an elevated sodium level what does that mean I have consumed … potatoes chips. The water and blood in the cells is going to come out of the cells and go into the blood stream causing dehydration. (this happens in the cells) -LOW sodium will do the opposite which is causing the water to go into the cells causing it to swell. CELLULAR EDEMA. In vital area will cause a huge problem esp. in the skull it will run out of room. 2. Active Things that create the movement of water 1. Oncotic pressure (helps pull into the cell) 2. Hydrostatic pressure (pushes the fluid out of the blood stream) QUESTION: what else is there to help with excess fluid: the lymph tissue The cells have 1. Electrolytes 2. Carb 3. Protein 4. Fat Scenario: If I eat a bag of donuts what’s my blood sugar going to do? GO up which stimulates my brain to releases more insulin. Bind with sugar and then can cross the cell membrane. SUGAR is out of the blood and now into the cells. INSULIN is now metabolized. GLUCOSE AND ISNULIN = SYMPORT SINGLE MOLECULE IN ONE DIRECTION= UNIPORT SODIUM AND POTASSIUM CROSS in OPPOSITE DIREECTIONS= ANTIPORT. - when this happens the cell membrane they repel each other that creates energy. MUSCULES WILL CONTRACT WITH THIS ........................................................................................continued.................................................................................
