> 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.
DKA. ANSWER - increased anion gap, decreased HCO3
How do kidneys compensate for alkalosis. ANSWER - retain H and excrete HCO3
Untreated acidosis leads to an increase in which electrolyte?. ANSWER - Potassium

malignant neoplasm. ANSWER - uncontrolled new tissue growth, irregular borders,
spreads

become porous, brittle, and easily fractured.
osteomalacia. ANSWER - disease marked by softening of the bone caused by calcium and
vitamin D deficiency
myoglobin. ANSWER - red pigment that stores oxygen in muscle cells
Bursa. ANSWER - fluid-filled sac that allows for easy movement of one part of a joint over
another
Rickets. ANSWER - a vitamin D deficiency in children, resulting in soft bones
Degenerative disk disease. ANSWER - A condition in which an intervertebral disk loses its
