Which cells in the lymphatic system phagocytize foreign substances?

A

Macrophages

18
Q

Red Bone marrow function

A

Site of B lymphocytes

19
Q

Thymus function

A

maturation of T lymphocytes

20
Q

Lymph nodes function

A

Filters lymph and where immune response starts

21
Q

A

Filters blood

immune response starts when a substance is in the blood

Removes RBC and WBC

22
Q

Tonsils Function

A

Protection from inhaled and ingested substances

23
Q

Lymph Nodes Function

A

protects organs from foreign substances

A

Neck
armpits
chest
abdomen
groin

26
Q

What is the function of light staining centers in lymphoid follicle?

A
27
Q

What is the relationship between the number of afferent and efferent lymphatic vessels that enter and leave a lymph node?

A

There are 4 different vessels and 2 efferent vesicles at the end

28
Q

what are the steps of lymph moving through the afferent lymphatic vesicle to the efferent lymphatic vessel?

A
  1. afferent vessicle
  2. subscapular sinus
  3. medulla sinus
  4. drains from efferent
    exits from hilus in lymph node
29
Q

When is the thymus most active?

A

Childhood until puberty

30
Q

What affect does age have on the thymus?

A

declines in function

31
Q

32
Q

Which tonsil is not paired?

A

pharyngeal

33
Q

What happens to the flow of lymph when the lymphatics are blocked?

A

causes a build-up of fluids, lymphodema(swelling)

34
Q

What is bubo?

Swollen lymph in armpit or groin

35
Q

What do swollen lymph nodes indicate?

Infection

36
Q
