Back 4

3 osmolarities

Front 5

What is Osmosis

Back 5

Water movement to make concentrations equal.

Front 6

Isotonic concentrations are__________.

Back 6

Equal

Front 7

What happens to the blood pressure as salt intake is increased?

Back 7

Blood water is retained, then blood volume increases, then blood pressure increases.

Front 8

Anhydrobiosis

Back 8

A dormant state without water.

Front 9

What are Osmoregulators?

Back 9

They use energy for water uptake/loss to maintain osmolarity between a certain range.

Front 10

What are osmoconformers?

Back 10

Same blood osmolarity as their surroundings.

Front 11

Stenohaline

Back 11

Cannot tolerate high fluctuation in external osmolarity.

Front 12

Euryhaline

Back 12

Can tolerate changes in environment's osmolarity.

Excretion

Front 18

What is Filtration?

Back 18

Filtering of body fluids from capillary to nephron

Front 19

reabsorption

Back 19

reclaiming valuable solutes from the nephron into the capilary

Front 20

Secretion

Back 20

adding nonessential solutes and waste from the capillary to the nephron.

Front 21

excretion

Back 21

Nitrogenous waste, nonessential solutes and water released from the body

Back 22

Amino Acids
H2O
Glucose
NaCl
Vitamines

Front 23

I the kidney what is the glomerulus?

Back 23

the site where filtration of body fluid begines into the nephron.
Capillary and bowmans Capsule

Front 24

What is the first part of the nephron after the Glomerulus?

Back 24

proximal tubule

Front 25

What is the complete nephron pathway after the glomerulus?

Back 25

Proximal tubule
loop of Henle
Distal tubule
Collecting duct

If a reabsorption or secretion does not use ATP it is ______

Back 26

passive transport

Front 27

Loop of Henle is made of 2 parts.

Back 27

Descending limb and ascending limb
