More than one of the above hormones promotes diuresis Which of the following statements is/are TRUE? A. Sodium is the most abundant intracellular cation. B. Hormones controlling sodium levels include aldosterone, ADH and ANP. C. Sodium is involved in impulse transmission and muscle contraction. D. Two of the above statements are true. E. All of the above are true. Chloride: A. In excess, is known as hyperkalemia B. Plays a role in regulating osmotic pressure C. Levels are directly controlled by aldosterone D. Two of the statements above are true E. All of the above are true Calcium: A. Is mainly an extracellular ion, and the most abundant ton in the body B. Plays a role in blood clotting, neurotransmitter release and the excitability of nervous and muscle tissue C. Levels are partially regulated by Vitamin D D. Two of the statements above are true E. All of the above are true Which of the following is/are means of maintain the body's pH: A. Renal excretion of H^+ ions B. Respiration C. Buffers D. Both A and C. E. All of the above

Explanation / Answer

44) more than one hormone promotes diuresis

Above hormones sense low or high level of water in body and release more water in urine in case of more amount of water in blood and reduces water loss in case of low water levels in blood.

45) Two staments are correct

Sodium ions are involved in muscle contraction and cell signalling. Sodium ions are present in excess in extracellular fluid.Regulated by ADH,ANP and aldosterone hormones.

46) two statement's are true

Chloride maintain osmotic pressure in body and are controlled by aldosterone hormones

47) All of the above

Calcium is most abundant mineral in human body required for maintenance of bones,teeth and skeleton which helps in signalling and blood clotting mechanism's regulated by presence of vitamin D.

48) From all of the above body PH is maintain.

Excess of hydrogen ions are expelled by lungs which are attached as carbonates and large amount hydrogen ions are excreted in urine bringing back PH to normal.Buffers like carbonic acid and bicarbonates maintain basic character in blood.
