Hypertonic cells - Study guides, Class notes & Summaries

What is the body's defense against ROS? Antioxidants (Vitamin E, Vitamin C, cysteine, glutathione, albumin, ceruloplasmin, transferrin) How does a hypertonic solution alter osmolality? Increases solute concentration, causing INCREASED osmolality. Causes cells to SHRINK. What lab values are elevated as we age? Interleukin 1, tumor necrosis factor-alpha, and C-reactive protein Role of hepatocytes Acetyl CoA is processed by hepatocytes and transforms to 3 ketone bodies: 1. Acetoa...

minimum urine output for adult 0.5mL/kg/hr ADH (antidiuretic hormone) - water retainer - vasoconstrictor (also called Vasopressin) - produced by hypothalamus - store and released from posterior pituitary ADH pathway - hypothalamus senses low blood volumed and increased serum osmolality - signal pituitary to release ADH - ADH causes kidney to retain water - water retention increases blood volume and decreases serum osmolality ANP (atrial natriuretic peptide) -...

What is tonicity? Correct Answer the ability of a solution to change shape or tone of cells by altering the cells internal water volume. A solution's tonicity depends on the solution's concentration of nonpenetrating solutes (e.g., NaCl) relative to that in the cell, not on the total osmolarity of the solution. Tonicity provides the information on how the solution affects the cell's volume - Why does it matter if a cell is hypertonic or hypotonic? - Water movement depends on what type of...

isotonic fluids Correct Answer-normal saline and D5W have a concentration of dissolved particles equal to that of the ICF. Osmotic pressure is the same inside and outside the cells, so they neither shrink nor swell with fluid movement. hypertonic solutions Correct Answer-3% saline, D5 in normal saline, D5 in half normal saline, and D10 in normal saline Has a tonicity greater than that of the ICF, so osmotic pressure is unequal inside and outside of the cell. Dehydration or rapid infusion of...
