1.11 Fluid Copartments And Solutesm

Question 1

Plasma vs interstitial fluid

Answer 1

Plasma has more protein

Question 2

Osmolarity

Answer 2

Measure of the concentration of all solute particles in a solution

Question 3

How many osmoses in nacl

Answer 3

2 (na+ and cl-)

Question 4

How many osmoses in glucose

Answer 4

1

Question 5

How many osmoses in cacl2

Answer 5

3

Question 6

Diffusion

Answer 6

Spontaneous movement of a solute down a concentration gradient until the solute molecules reach and equilibrium

Question 7

Osmoles

Answer 7

Number of moles of solute that contribute the osmotic pressure of a solution

Question 8

Osmosis

Answer 8

Movement of water down its own conc g toward an area of higher osmolarity

Question 9

Hypertonic solutions

Answer 9

Cell shrinks when placed in the solution

Osmolarity of solutes greater outside

Question 10

Hypotonic solutions

Answer 10

Cell swells when in the solution

Osmolarity of solutes is greater inside

Question 11

Isotonic solution

Answer 11

Cell volume is unchanged

Osmolarity of solutes is equal both sides of the membrane

Question 12

How are cell volumes maintained

Answer 12

By actively pumping ions

Question 13

UW solution factors to reduce cell swelling

Answer 13

Lack of na or cl

Presence of Extracellular solutes

Presence of starch

Antioxidants

Question 14

COP

Answer 14

Colloid osmotic pressure

Question 15

When is cop generated

Answer 15

Higher conc of plasma proteins inside capillaries

Question 16

How is hydrostatic pressure generated

Answer 16

Blood flow through the tissue

Question 17

Oedema

Answer 17

Excess fluid loss from capillary to interstitial fluid

Question 18

How do lymphatic capillaries combat the loss of plasma fluid into tissues

Answer 18

Collect interstitial fluid for redistribution

Question 19

Why does an overweight man have swollen feet

Answer 19

High bp Inc hydrostatic pressure in vessels pushing fluid out into interstitial space

Question 20

Why does breast cancer survivor have fat arm

Answer 20

Lymph nodes removed in treatment so IF can’t flow into lymph capillaries and be redistributed
