Question 16 Mark this question Select the statement that describes the filtration stage of urine formation. Water and other small solutes are separated out of the blood in the Bowman's capsule. During this third step of urine formation, urine filters into the ureters and ultimately to the urinary bladder for storage. To maintain the body's acid-base balance, substances move from the blood in the peritubular capillaries into nephron tubules. The bloodstream retrieves valuable substances that have been separated out during this second step of urine formation. UNIT 5 5.1 The 5.1 5.1. 5.1.3 5.1.4 5.1.5 5.1.6

39. Bowman's capsule & glomerulus is known as: renal corpuscle 40. During filtration, filtrate moves from glomerulus to: Bowman's capsule 41. Blood to be processed is brought to the kidney by: renal artery 42. From renal calyx urine empties into: renal pelvis 43. From renal papilla urine moves into: renal pelvis 44. From collecting ducts urine empties into: renal pelvis 45. The functional unit of kidney where blood processing and urine formation occurs: nephron 46. Process that moves good and bad materials from blood to Bowman's capsule: filtration 47. Primary site of tubular reabsorption: PCT (proximal convoluted tubule) 48. Process that moves materials from filtrate to blood: reabsorption 49. Excess H+ is removed from blood and moved to filtrate by the process of: secretion 50. Starling's forces that drive filtration: HP (hydrostatic pressure) and OP (osmotic pressure) 51. HP at the glomerulus is high because efferent arteriole is narrower than afferent arteriole 52. Urine output is regulated by these hormones: ADH (antidiuretic hormone), ANH (atrial natriuretic hormone), Aldosterone 53. Which process in urine formation allows the blood to retain most body nutrients? reabsorption 54. Three important steps in urine formation: filtration, reabsorption, secretion 55. Juxtaglomerular apparatus is located where DCT (distal convoluted tubule) touches afferent arteriole 56. Reabsorption & secretion occur between nephron tubule and peritubular capillaries 57. Peritubular capillaries are formed from efferent arteriole 58. Secretes renin when blood pressure in afferent arteriole drops: juxtaglomerular apparatus 59. Filtrate moves in this sequence through nephron tubule: Bowman's capsule, PCT, loop of Henle, DCT, collecting duct 60. Dialyzed, clean blood exits kidney via: renal vein 61. Glomerulus is formed from: afferent arteriole 62. Water makes up __ of urine: variable (not specified in the text) 63. Nitrogenous wastes such as ammonia, urea, creatinine are generated during: protein metabolism
Filtration: In the process of producing urine, this is the first step. Blood pressure pushes the blood through the filtration membrane. It allows water and small molecules to pass through but blocks larger particles such as proteins and plasma to stay in the blood stream. The liquid that passes through the filtration is called the filtrate and continues further into the nephron. Reabsorption- This is the second step in urine creation. After the filtrate leaves the glomerulus, it goes into a duct in the nephron called the renal tubule. As the filtrate moves the needed nutrients and some water are reabsorbed into the tube wall into adjacent capillaries. Secretion- This is the third step in urine creation. After the needed nutrients and water are reabsorbed, waste and hydrogen ions pass from the capillaries into the renal tubule. This liquid is known as secreted ions. They are then combined with the remaining filtrate. This liquid is now known as urine. Excretion- The urine then flows out of the nephron tube, into a collecting duct. “It passes out of the kidney through the renal pelvis, into the ureter, and down to the bladder” (Body, n.d.).
