Question

5U The renal corpuscle has two components: the glomerulus and Bowman's capsule S7 The first portion of the loop of Henle dips into the medula where i is called the ascending limb of the loop of Henle. 52 A juxtamedullary nephron usually has its glomerulus deep in the cortex close to the medulla, and it long loop of Henle stretches through the medula 51,The juxaglomerular aparatus helps regulate blood pressure and the rate of blood filtration by the kidneys o Each renal corpuscle receives one efferent arteriole, which divides into the tangled capilary network called the glomerulus 01 Each efferent arteriole of a cortical nephron divides to form a network of capillaries, called the peritubular capillaries. ,The first step in the production of urine is called tubular reabsorption. 43.When blood flows into the glomerular capillaries more rapidiy. glomerular filtration rate decreases. 6 Juxtaglomerular cells secrete an enzyme called renin in response to several kinds of stimuli. kS,Normally, 100% of the filtered glucose, amino acids, lactic acid, and other metabolites are reabsorbed in the distal convoluted tubules. possibiy useful 66,The renal threshold is the plasma concentration at which a substance begins to spill into the urine because its transport maximum has been surpassed. 7Aldosterone, secreted by the adrenal cortex, brings about increased sodium ion and water reabsorption by the principal cells.

Explanation / Answer

Answers:

56) True

57) False. The first portion of the loop of henle is called the thin descending limb of loop of henle.

58) True

59) True

60) False. The renal corpuscle which receives blood is called the afferent arteriole.

61) True

62) False.The first step in urine production is called glomerular filtration, second step is tubular reabsorption and the third step is called tubular secretion.

64) True

65) False.100% of glucose, amino acids and lactic acid are reabsorbed in the middle portion of the proximal convoluted tubules.

66) True.

67) True.Principal cells are found in the distal; tubules and collecting ducts of the nephrons which help in regulation of sodium, potassium and water regulation.
