Filtration,reabsorption,and Secretion 14.3

Front 1

What is the functional unit of the kidney?

Back 1

The Nephron

Front 2

Categorize the glomerulus

Back 2

Especiallized capillary bed, blood enters by afferent arteriole, leaves by efferent arteriole.

Front 3

Fenestrated pores

Back 3

Filtration occurs

Front 4

At the glomerular capsule, proteins are not usually present, but glucose is. True or False

Back 4

True

Front 5

Most of the obligatory reabsorption of water occurs at the;

Back 5

Collecting duct

Front 6

Identify the affect of aldosterone on the collecting duct

Back 6

Increase retention of water

Front 7

Identify the hormone that regulates reabsorption of water from the collecting duct

Back 7

ADH

Front 8

How will ADH affect the concentration of urine produced?

Back 8

Reabsorbs the H2O NAC1-increase UREA 1increase

Front 9

Identify the mechanism of membrane transport that drives water through aquaporing channels

Back 9

Collecting ducts. ADH regulated aquaporing channels

Front 10

How will high concentrations of glucose in blood lead to elevated glucose in filtrate?

Back 10

Excess gluten in the filtrate, caused by type 1 diabetes, type 2 mellitus

Front 11

How will glucose in the filtrate affecet reabsorption of water in the collecting ducts?

Back 11

Glucose transporters cannot reabsorb that glucose, glucose brings more H2O back in. Increase retention if water

Front 12

How glucose in the filtrate affect urine volume?

Back 12

Brings more H2O back in excess urine production

Front 13

How qould aldosterone affect sodium reabsorption?

Back 13

Helps to keep more of the NaCl (sodium) water follows sodium

Front 14

How would aldosterone affect water reabsorption in the collecting ducts?

Back 14

Water follows the sodium out, increase bloid volume, increase blood pressure
