Question
Answer the following Multiple choice questions below:
At any given PO2, which of the following will lead to an increased hemoglobin saturation?
1) Decreased pH of the blood.
2) Decreased acidity of the blood.
3) Increased temperature of the blood.
4) Increased levels of DPG in the blood.
5) Increased PCO2 of the blood.
Renin
1) binds to receptors on vascular smooth muscle, causing contraction.
2) concentration in the blood is elevated during periods of low blood pressure.
3) is secreted by the adrenal cortex.
4) secretion is stimulated by angiotensin II.
5) all of the above.
The urine of a patient with untreated diabetes mellitus contains glucose because
1) glucose is secreted into the distal tubules in diabetes mellitus.
2) the amount of glucose filtered exceeds the transport maximum for glucose reabsorption
3) the large urine volume in the tubules inhibits glucose reabsorption
4) the renal tubules cannot reabsorb glucose unless insulin is bound to tubular receptors
Explanation / Answer
Answer ) the answer is 2 that is decreased acidity of the blood which means that the basicity is increased and under basic ph heamoglobin is free to bind with oxygen and the association is increased.
Answer) the answers of the above question is 2 because itsitprimary parole is in maintaining blood pressure and is secreted by juxtaglomerular nephron in kidney and convert angiotensin 1 into angiotensin ll .
Answer) this condition is also known as glycosuria in which some glucose remain intheinurine because blood concentration of glucose increase which cause all the transport system of the renal tubules of occupied and then glucose enters glomerular filtrate. So the answer is 2 for the above question.
