Module 2 Revised

Question 1

Diffusion is the migration of particles from HIGHER to LOWER concentration.

Answer 1

T

Question 2

Osmosis is the movement of water molecules that occurs in ONE direction across a semi permeable membrane.

Answer 2

T

Question 3

Colloid Osmotic Pressure of the plasma (COPpl) is the force of proteins in the blood to hold water.

Answer 3

T

Question 4

Blood pressure in arteries is higher than blood capillary pressure.

Answer 4

T

Question 5

In healthy individuals, the Colloid Osmotic Pressure of protiens located in the interstitium (COPip) is greater than the Colloid Osmotic Pressure of the plasma (COPpl).

Answer 5

F

Question 6

The precapillary sphincter is innervated by the sympathetic portion of the Autonomic Nervous System (ANS).

Answer 6

T

Question 7

If the precapillary sphincter dilates = Less blood into capillaries –> Less volume = decreased Blood Capillary Pressure (BCP).

Answer 7

F

Question 8

Starling’s Law states that the average Blood Capillary Pressure (BCP) equals the average Colloid Osmotic Pressure of the plasma proteins (COPpl).

Answer 8

T

Question 9

Complete Decongestive Therapy (CDT) attempts to restore normal diffusion distance and prevent re-accumulation of fluid.

Answer 9

T

Question 10

The Functional Reserve (FR) of the lymphatic system enables the lymphatic system to respond to an increase in lymph fluid volume with an increase in Lymph Time Volume (LTV).

Answer 10

T

Question 11

If the normal diffusion distance in the tissues between the cells and the blood capillary increases (if swelling is present):

Answer 11

a. The local immune response in the tissue cells is compromised
b. The nutritional supply to the cells will suffer
c. Patient is prone to frequent infections

Question 12

All these statements are correct about the diffusion distance except:

Answer 12

Normal diffusion distance is 1 cm

Question 13

When the precapillary sphincter located at the arteriole contracts:

Answer 13

a. Less blood enters into the capillaries
b. Volume will decrease and the Blood Capillary pressure will also decrease
c. Less filtration occurs

Question 14

What upsets the equilibrium of Starling’s Law?

Answer 14

b. Passive Hyperemia

c. Active Hyperemia

Question 15

If a healthy lymphatic system is overwhelmed and the lymphatic load of water exceeds the Transport Capacity (TC) with a Lymph Time Volume (LTV) maxed out this is called:

Answer 15

Dynamic insufficiency

Question 16

Hypoproteinemia:

Answer 16

Abnormal deficiency of the amount of protein in the blood

Question 17

Dynamic insufficiency

Answer 17

Healthy lymphatic system is overwhelmed, high volume insufficiency

Question 18

Mechanical Insufficiency

Answer 18

Transport capacity drops below the normal amount of lymphatic load, low volume insufficiency

Question 19

Lymph time volume

Answer 19

Amount of lymph transported in a unit of time

Question 20

Functional reserve

Answer 20

Back-up of lymphatic system - Amount of compensation

Question 21

Edema

Answer 21

Abnormal accumulation of water in the tissue

Question 22

Filtration

Answer 22

Transport of a solution through a filter, provided the membrane is permeable to water

Question 23

Transport capacity

Answer 23

The maximum amount of lymph transported with the lymphatic system working as hard as possible in a given length of time

Question 24

Reabsorption

Answer 24

Process by which water is reabsorbed from the tissues back into the venous end of the blood capillary

Question 25

Lymphedema

Answer 25

Abnormal accumulation of protein rich fluid in the tissue
