- _____________ in the hypothalamus monitor blood Na+ and when necessary trigger vasopressin secretion.What effect does an increase in antidiuretic hormone (ADH) have on the volume of extracellular fluid (ECF)? a. ECF decreases when antidiuretic hormone (ADH) is present. b. ECF increases initially, then decreases when antidiuretic hormone (ADH) is present. c. ECF increases when antidiuretic hormone (ADH) is present. d. Antidiuretic hormone (ADH) has no effect on ECF.caffeine is also diuretic, which means it increases the movement of water through the kidneys into the urine. Why would this potentially offset its value to a distance athlete?
- Caffeine and nicotine have excitatory effects because they: reduce the threshold for excitation increase the threshold for excitation open potassium ion leakage channels open chemically-gated chloride ion channels close chemically-gated calcium ion channels ( explain deeply with step by step type the answer).Nicotinic receptors bind A. acetylcholine and allow chloride ions to exit the cell. B. acetylcholine and allow sodium ions to enter the cell. C. muscarine and increase the contractility of intestinal muscle. D. norepinephrine and can either stimulate or inhibit the cell. E. norepinephrine and allow potassium entry, thereby exciting the cell.If a person is given an experimental drug, which response would indicate that this drug is an norepinephrine/epinephrine agonist? decreased blood pressure pupil constriction constriction of respiratory airways high blood sugar (hyperglycemia) decreased heart rate

Answers to choose: A urine potassium of 35 mmol/d, A urine potassium of 21 mmol/d?, A spot urine test where the sodium levels are greater than potassium levels?, Have long half-lives?, Circulating blood catecholamines are 99% bound to albumin?, Mone of the above accurately describes catecholamines? no references, just homework.Consider the effect of a twofold increase in the ECF concentration of Na+ or K+ ions. Which increase in ion concentration is the more deadly and why? Hint: Consider if the calculated decrease in or the increase in bring the resting membrane potential of the nerve or muscle cell closer to threshold potential?
