Filter lymph

Question 17

What is the function of tonsils

Answer 17

filter air

Question 18

What is the function of the thymus

Answer 18

produce thymic factors
it helps in setting up immune system and the formation of t lymphocytes

Question 19

What is the function of the spleen

Answer 19

Filters blood

Question 20

What is Peyers patches

Answer 20

type of lymph nodule

Question 21

What does the right duct drain and return it to

Answer 21

upper right of the body and right arm
return lymph to the right subclavian vein

Question 22

What does the left duct drain and return it to

Answer 22

upper left side of the body and lower body
return lymph to the left subclavian vessel

Question 23

when is the immune system most active

Answer 23

at childhood as the thymus is at its largest

Question 24

Pressure exerted by large molecules that help to pull and hold fluid (water) inside the vascular space is known as
a) interstitial fluid pressure
b) systolic blood pressure
c) Hydrostatic pressure
d) colloidal osmotic pressure

Answer 24

d

Question 25

Lymphatic capillaries intertwined with what

Answer 25

capillary bed of the blood vascular system

Question 26

why is the lymphatic vessels intertwine with the cardiovascular system

Answer 26

cardiovascular capillaries are under pressure blood is forced out of the blood vessels network and into outside space but this blood is needed for the body So lymphatic vessels suck up interstitial fluid and take it back into the cardiovascular system in a later stage.

Question 27

what is hydrostatic pressure what does it cause

Answer 27

force exerted by a fluid between the arterial end (lots of pressure) and venous end (less pressure) force the plasma inside blood vessels to cross the cell membrane and goes in-between tissue cells

Question 28

what is colloidal osmotic pressure

Answer 28

force caused by the difference in the amount of proteins that is present inside than outside draws fluid back in due to the large proteins that are to large to pass through the membrane. osmotic pressure goes from high to low concentration

Question 29

blood plasma that has been pushed out of the blood capilarries that located between tissue cells is called

Answer 29

interstitial fluid

Question 30

Name a blood protein that is too large to leave the capillary that creates this osmotic pressure

Answer 30

albumin

Question 31

What do the lymph capillaries do

Answer 31

collects the interstitial fluid

Question 32

What is the interstitial fluid known as when enter the lymphatic capillaries

Answer 32

lymph

Question 33

What are the important structure of the lymphatic capillaries

Answer 33

blind ended vessels to ensure the one main movement of the fluid when it gets inside the vessel. mini valves that allow fluid inside but do not allow back flow of fluid

Question 34

What type of pressure does lymph have to interstitial fluid

Answer 34

Low pressure

Question 35

lymph capillaries join and form

Answer 35

lymph vessels get larger when you get closer to the heart

Question 36

four factors that influence oedema

Answer 36

increase capillary filtration pressure decrease colloidal osmotic pressure Increase capillary permeability obstruction to lymph flow

Question 37

where are lymph nodes located

Answer 37

along lymph vessels

Question 38

What does lymph nodes do

Answer 38

filter lymph to look and see any pathogens and bacteria

receive the lymph

Question 40

What does the efferent vessels in the lymph node do with the lymph

Answer 40

drain it

Question 41

what has more afferent lymphatic vessel or efferent lymph vessels

Answer 41

afferent vessels because they allow immune cells to look to see what shouldn't be in there.
