The kidneys are responsible for removing excess H+ ions from the blood. If the kidneys fail, what will happen to
Step by step
Solved in 2 steps
- Why is excretion important in order to achieve osmotic balance?Explain how the kidneys help to maintain the balance of acids and bases in extracellular fluid.As the text noted, two-thirds of the water and solutes that the body reclaims by reabsorption in nephrons occurs in the proximal tubule. Proximal tubule cells have large numbers of mitochondria and demand a great deal of oxygen. Explain why.
- A urinalysis reveals that the patients urine contains glucose, hemoglobin, and white blood cells (pus). Are any of these substances abnormal in urine? Explain.The body loses water by way of the ________. a. skin b. lungs c. digestive system d. urinary system e. both c and d f. a through dHow is the urine affected when the body compensates for respiratory alkalosis (which can occur when the lungs too efficiently get rid of the carbon dioxide present in the blood, for example during hyperventilation)?
- Describe the mechanisms by which the kidneys regulateblood volume and erythrocyte production.Using knowledge of nephron function, how would blocking Na+ transport help to reduce blood pressure so pulmonary edema does not occur?If a substance in the blood is filtered, and not all of it is completely reabsorbed back into the blood, does its level in the blood increase, decrease, or stay the same? Explain.
- In a person who suffers acidosis, the way to counteract the condition is by: Drink a large amont of water Slow Breathing Inhale a greater amount of CO2 than normal Stop breathing Fast and deep breathingPressure sensing by the kidneys is a better surrogate for: A. Heart rate B. Stroke volume C. Cardiac output D. Differences in water concentration between the intracellular and extracellular compartmentsTubular secretion of hydrogen ions ceases ifthe acidity of the tubular fluid falls below avalue called the-----------------------------
