Unit 2A Flashcards
Define capillary exchange
Involves filtration and Reabsorption
Name of all the ways that capillary exchange happens
Diffusion, transcytosis and bulk flow
Dtb
Difference between filtration and reabsorption
From capillaries into interstitial fluid
From blood pressure (heart)
And reabsorption from interstitial fluid into capillaries.
From viscosity proteins like albumin
Which pressures favor filtration?
Hydrostatic pressure
Which pressures favors reabsorption
Osmotic
what is NFP?
Whether fluids leave or enter capillaries depends on net balance of pressures: filtration and Reabsorption
The starling law of capillaries…
About 85 % goes back to your veins and escaped fluid is 3/ liters a day. By lymphatic capillaries
Edema is the abnormal amount of I.F if filtration exceeds reasorption
the abnormal amount of I.F if filtration exceeds reasorption.
What are the two results of edema
Excess filtration, inadequate reasorption
Why is edema commonly observed at late pregnancy
The obstruction posed by the uterus on the inferior vena cava, and this decreases cardiac output, leads to a fall in blood
pressure
A pulse is a ….
pressure wave related to the heart beat
Where can the pulse be measured?
Radial, brachial, and common carotid artery , femoral, popliteal and dorsal
Measuring Blood Pressure
BP provides information
about…
Systemic vascular
resistance
korotkoff sounds are
Sounds heard while taking blood pressure
What is MAP. Stand for
Mean of arterial pressure
Which factors affect blood pressure
Cardiac output CO, blood volume, peripheral resistance to arteries
the major componets of lymph does NOT include :

Which of the following is NOT an example of lymphatic tissue ?
Microvilli
The __________ tonsils are the largest, and their surgical removal (tonsillectomy) used to be one of the most common surgical procedures performed in children.
Palatine
________ participate in both Cell-mediated and Antibody-mediated immunities.
Helper T cells
_____ is not involved in Cell-mediated immunity.
plasma cells
Which of the following is common in the distal small intestine?
Aggregated lymphoid nodule
One characteristic of the immune response is specificity. This means that __________.
immunity is directed against a particular pathogen
The__________ show(s) a remarkable degree of degeneration (involution) with age.
Thymus
Complement C3b protein coats bacteria and stimulates phagocytosis by __________.
Neutrophils and macrophages
These anti-microbial substances promote cytolysis, phagocytosis and inflammation.
Defensins
Transferrin and ferritin are considered anti-microbial proteins. Because they inhibit certain bacteria by reducing the available ________ through binding.
Iron
__________ is not a cardinal sign characteristic of inflammation.
Loss of function
These anti-microbial substances will diffuse to neighboring uninfected cells and reduce production of viral proteins.
Interferons
When an enemy cell is present, a(n)__________ secretes perforins, which bore a hole in the enemy cell membrane.
Natural killer cell
Which of the following WBCs are NOT considered the second line defense?
Lymphocytes
The first line defense does NOT INCLUDE _________.
Inflammation
