Module 2

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 proteins 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 which means 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.

Answer 8

T

Question 9

Complete Decongestive Therapy (CDP) 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.
D. All of the above
Answer: D

Question 12

All of these statements are correct about diffusion distance except:

Answer 12

A. Swelling increases the diffusion distance
B. If swelling is present-the local immune response is compromised and nutritional supply to cells suffers.
C.Normal diffusion distance is 1cm.
D. Compressions will help decrease diffusion distance.
Answer: C (diffusion distance is 1/10mm)

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.
D. All of the above.
Answer: D

Question 14

What upsets the equilibrium of Starling’s Law?

Answer 14

A. Women
B.  Passive hyperemia
C.  Active hyperemia
D.  Both B & C
Answer: D

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

A.  Dynamic insufficiency
B.  Mural insufficiency
C.  Mechanical insufficiency
D. Combined insufficiency
Answer: A

Question 16

Hypoproteinemia:

Answer 16

A. Increased level of protein in blood.
B. Abnormal deficiency of the amount of protein in the blood.
C. Increased level of protein in the interstitium.
D. Abnormal deficiency of glucose in the blood.
Answer: B

Question 17

Define Edema:

Answer 17

Abnormal accumulation of water in the tissue.

Question 18

Define Functional Reserve:

Answer 18

Back-up of the lymphatic system - Amount of compensation.

Question 19

Define Reabsorption

Answer 19

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

Question 20

Define Dynamic Insufficency:

Answer 20

Healthy lymphatic system is overwhelmed, high volume insufficiency.

Question 21

Define Mechanical Insufficiency:

Answer 21

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

Question 22

Define Filtration:

Answer 22

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

Question 23

Define 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

Define Lymphedema:

Answer 24

Abnormal accumulation of protein rich fluid in the tissue.

Question 25

Define Lymph Time Volume:

Answer 25

Amount of lymph transported in a unit of time.
