Afferent arteriole, glomerular capillaries, efferent arteriole, peritubular capillaries c. Efferent arteriole, afferent arteriole, glomerular capillaries, peritubular capillaries d. Afferent arteriole, glomerular capillaries, peritubular capillaries, efferent arteriole tubular capillaries 88. As a result of renin-angiotensin-aldosterone system: Aldosterone is secreted from pituitary gland Arteriolar vasoconstriction occurs ADH is produced by adrenal cortex Arteriolar vasodilation occurs a. b. C. d. 89. Which of the following increases the rate of glomerular filtration? a. b. c. d. Decrease in blood pressure Increase in blood pressure Vasoconstriction of afferent arteriole Vasodilation of efferent arteriole 90. Immunity from injecting gamma globulin antibodies into another individual is: a. Active natural immunity b. Passive artificial immunity c. Active artificial immunity d. Passive natural immunity 91. Organ responsible for maturation of T lymphocytes is: a. Thymus b. Thyroid c. Lymph nodes d. Pancreas 92. All of following are part of respiratory tract except: a. Trachea b. Bronchi e. Larynax d. Esophagus Which of following organs have both exocrine and endocrine functions? a. Spleen b. Liver 93. Pancreas d. Gall bladder 94. Blood from head is returned to the heart via a. Inferior vena cava b. Superior vena cava c. Gastric vein d. Renal vein 95. Red blood cell production occurs in: a. Red bone marrow b. Thyroid ?. Spleen d. Stomach

Explanation / Answer

87. b. The blood in the glomerular capillaries is brought by the afferent arterioles and exit through the efferent arterioles. In the end this blood is taken to the peritubular capillaries of the tubules

88. Arteriolar constriction occurs. This is because the last hormone secreted as a result of this system, aldosterone is secreted by adrenal glands which acts on the arteries which result in constriction which increases the blood pressure.

89. Increase in afferent arterioles

90. Passive artificial immunity

91. Thymus

92. Esophagus is a part of digestive system

93. Liver.

94. Inferior Vena Cava

95. Red bone marrow
