Module 2 Revised 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 protiens 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 –> 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 (COPpl).
T
Complete Decongestive Therapy (CDT) 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
All these statements are correct about the diffusion distance except:
Normal diffusion distance is 1 cm
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
What upsets the equilibrium of Starling’s Law?
b. Passive Hyperemia
c. Active Hyperemia
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:
Dynamic insufficiency
Hypoproteinemia:
Abnormal deficiency of the amount of protein in the blood
Dynamic insufficiency
Healthy lymphatic system is overwhelmed, high volume insufficiency
Mechanical Insufficiency
Transport capacity drops below the normal amount of lymphatic load, low volume insufficiency
Lymph time volume
Amount of lymph transported in a unit of time
Functional reserve
Back-up of lymphatic system - Amount of compensation
Edema
Abnormal accumulation of water in the tissue
Filtration
Transport of a solution through a filter, provided the membrane is permeable to water
Transport capacity
The maximum amount of lymph transported with the lymphatic system working as hard as possible in a given length of time
Reabsorption
Process by which water is reabsorbed from the tissues back into the venous end of the blood capillary
Lymphedema
Abnormal accumulation of protein rich fluid in the tissue
