1. Physiology exam

2. TRUE OR FALSE 1 . Proteins and cells can easily be filtered out of glomerular filtration in glomerular capillaries. 2. Sympathetic nervous system increases the renal blood flow and decrease Glomerular filtration rate. 3. Filtration in the glomerulus is an active process driven by energy from ATP. 4. The kidneys produce erythropoietin, which stimulates red blood cell production in the bone marrow. 5. The kidneys can compensate for metabolic acidosis by excreting more bicarbonate ions.

3. choose 6. Which of the following is true about Renin Angiotensin Aldosterone mechanism Increased secretion of Aldosterone and ADH Decrease intravascular volume decrease blood pressure Decrease Plasma osmolarity 7. Which one of the following is not functions of Kidney? Maintain body fluid osmolarity and volume Regulation of acid base and Electrolyte balance Excretion of waste products Cellular Immunity

4. 8. Urine formation depends on the following processes Glomerular filtration Tubular Secretion Tubular reabsorption All 9. Tubular secretion occurs for purpose of the following Except: To release any residues from toxins and drugs To establish electrolyte balance To maintain Acid base balance None 10. Which of the following conditions would most likely lead to an increased glomerular filtration rate (GFR)? Increased blood pressure Decreased blood flow to the kidneys Increased plasma protein concentration Increased renal sympathetic tone

5. 11. Which of the following structures is primarily responsible for gas exchange in the lungs? A) Trachea B) Bronchi C) Alveoli D) Bronchioles 12. What is the primary function of surfactant in the lungs? A) To increase the surface tension of alveolar fluid B) To reduce the surface tension of alveolar fluid and prevent alveolar collapse C) To facilitate the movement of oxygen across the alveolar membrane D) To enhance carbon dioxide exchange in the alveoli

6. 13. Which of the following factors primarily determines the efficiency of gas exchange in the lungs? The partial pressures of gases in the alveoli The rate of blood flow through the lungs The surface area and thickness of the alveolar-capillary membrane All of the above 14. What effect does a decrease in blood pH (acidosis) have on the rate of breathing? It decreases the rate of breathing It increases the rate of breathing It has no effect on the rate of breathing It causes an irregular breathing pattern

7. 15. In which part of the respiratory system does the majority of airway resistance occur? Trachea Bronchi Bronchioles Alveoli

8. A patient has hyperthyroidism due to a pituitary tumor. Which of the following sets of physiological changes would be expected? what happents to T3 and T4 TSH signs
