Module 5 Urinary System

Question 1

The fluid filtered through glomeruli is almost identical in composition to what?

Answer 1

Blood plasma

Question 2

Blood is filtered through the glomeruli and passes into the __________, where various transport processes convert it into urine

Answer 2

Nephrons tubular component

Question 3

On entering the kidney, the renal artery subdivides to ultimately form many small vessels known as _______

Answer 3

Afferent arterioles

Question 4

The afferent arterial delivers blood to the _________

Answer 4

Glomerulus

Question 5

The glomerular capillaries rejoin your dome another arteriole: the _______ through which ________ leaves the glomerulus

Answer 5

Efferent arteriole through which blood that was not filtered into the tubular component leaves the glomerulus

Question 6

What are the only arterioles in the body that drain from capillaries?

(Typically arterioles break you into capillaries that rejoin to form venules)

Answer 6

Efferent arterioles

Question 7

At which capillaries is there no oxygen or nutrients extracted from the blood and no waste products picked up?

Answer 7

Glomerular capillaries

Question 8

Arterial blood enters the glomerular capillaries through the ________ arterioles , and arterial blood leaves the glomerulus through the ________ arterioles

Answer 8

Arterial blood enters the glomerular capillaries through the AFFERENT arterioles, and arterial blood leaves the glomerulus through the EFFERENT arterioles

Question 9

The Efferent arteriole quickly subdivides into a second set of capillaries: the ________

Answer 9

The Efferent arteriole quickly subdivides into a second set of capillaries: the peritubular capillaries

Question 10

Which capillaries supply the renal tissue with blood and are important in exchanges between the tubular system and blood during the conversion of filtered fluid into urine?

Answer 10

Peritubular capillaries

Question 11

The _______ capillaries rejoin to form venules that drain into the _____ vein by which blood leaves the kidney

Answer 11

The Peritubular capillaries rejoin to form venules that drain into the Renal vein by which blood leaves the kidney

Question 12

The Nephrons tubular component is a hollow, fluid filled tube formed by a ______ layer of ____________ cells

Answer 12

The Nephrons tubular component is a hollow, fluid filled tube formed by a SINGLE layer of EPITHELIAL cells

Question 13

The tubular component begins at the ________: an expanded, double-walled invagination that cups around the glomerulus to collect fluid filtered from glomerular capillaries

Answer 13

The tubular component begins at the BOWMAN’S CAPSULE: an expanded, double-walled invagination that cups around the glomerulus to collect fluid filtered from glomerular capillaries

Question 14

Filtered fluid from the Bowmans capsule passes into the ________ tubule

Answer 14

Proximal

Question 15

Which structure of the tubular component lies entirely within the cortex and is highly coiled/convoluted throughout much of its course?

Answer 15

The Proximal Tubule

Question 16

Fluid passes from the proximal tubules into the ________: a sharp hairpin loop that dips into the Renal Medulla

Answer 16

Loop of Henle

Question 17

The loop of henle has top parts:

Answer 17

Descending limb and Ascending limb

Question 18

The ______ limb of the Loop if plunges from the cortex into the medulla

Answer 18

Descending

Question 19

The ________ limb of the loop of Henle traverses back up into the cortex returning to the glomerular region of its own nephron

Answer 19

Ascending
