Identify the organism responsible for the disease: HPV {Ans: Human papillomaviruses}A student asks the professor to explain what effect natriuretic peptides have during heart failure when the heart dilates. Which response by the professor is best? Stimulates antidiuretic hormones Inhibits antidiuretic hormones Stimulates renin and aldosterone Inhibits renin and aldosterone {Ans: ANS: D Natriuretic peptides inhibit renin and aldosterone during heart failure when the heart dilates. These make up a group of peptide hormones, including atrial natriuretic peptide (ANP), secreted from myocardial cells in the atria and brain natriuretic peptide (BNP) secreted from myocardial cells in the cardiac ventricles. When the heart dilates during volume expansion or heart failure, ANP and BNP inhibit sodium and water absorption by kidney tubules, inhibit the secretion of renin and aldosterone, vasodilate the afferent arterioles, and constrict the efferent arterioles. The result is increased urine formation, leading to decreased blood volume and blood pressure}Which dietary lifestyle choice has been associated with a decreased risk for developing colon cancer? Increased consumption of dairy products Increased consumption of foods containing vitamin C Decreased consumption of foods high in fat Decreased consumption of artificial food coloring {Ans: ANS: C A low-fat, high-fiber diet is
