Module 2 Flashcards
Diffusion is the migration of particles from HIGHER to LOWER concentration.
T
Osmosis is the movement of water molecules that occurs in ONE direction across a semi permeable membrane.
T
Colloid Osmotic Pressure of the plasma (COPpl) is the force of proteins in the blood to hold water.
T
Blood pressure in arteries is higher than blood capillary pressure.
T
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).
F
The precapillary sphincter is innervated by the sympathetic portion of the Autonomic Nervous System (ANS).
T
If the precapillary sphincter dilates =Less blood into capillaries which means Less volume=decreased blood capillary pressure (bcp).
F
Starling’s Law states that the average Blood Capillary Pressure (BCP) equals the average Colloid Osmotic Pressure of the plasma proteins.
T
Complete Decongestive Therapy (CDP) attempts to restore normal diffusion distance and prevent re-accumulation of fluid.
T
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).
T
If the normal diffusion distance in the tissues between the cells and the blood capillary increases (if swelling is present):
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
All of these statements are correct about diffusion distance except:
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)
When the precapillary sphincter located at the arteriole contracts:
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
What upsets the equilibrium of Starling’s Law?
A. Women B. Passive hyperemia C. Active hyperemia D. Both B & C Answer: D
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:
A. Dynamic insufficiency B. Mural insufficiency C. Mechanical insufficiency D. Combined insufficiency Answer: A
Hypoproteinemia:
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
Define Edema:
Abnormal accumulation of water in the tissue.
Define Functional Reserve:
Back-up of the lymphatic system - Amount of compensation.
Define Reabsorption
Process by which water is reabsorbed from the tissues back into the venous end of the blood capillary.
Define Dynamic Insufficency:
Healthy lymphatic system is overwhelmed, high volume insufficiency.
Define Mechanical Insufficiency:
Transport capacity drops below the normal amount of the lymphatic load, low volume insufficiency.
Define Filtration:
Transport of a solution through a filter, provided the membrane is permeable to water.
Define Transport Capacity:
The maximum amount of lymph transported with the lymphatic system working as hard as possible in a given length of time.
Define Lymphedema:
Abnormal accumulation of protein rich fluid in the tissue.
Define Lymph Time Volume:
Amount of lymph transported in a unit of time.
