Q

These WBCs appear orange-red and act in response to the presence of parasites / in parasitic infections

A

Eosinophils

24
Q

These WBCs appear bright-red and increases their activity during allergic reactions

A

Eosinophils

25
Q

These proteins are released by virus-infected cells to inhibit viral reproduction

A

Interferons

26
Q

These are proteins secreted from tears and saliva which can destroy certain pathogens that come in contact with the said secretions.

A

Lysozyme

27
Q

This property refers to the ability of the immune response to recognize and distinguish among various kinds of pathogen.

A

Specificity

28
Q

This property refers to the ability of the immune response to remember previous encounters with the same pathogen.

A

Memory

29
Q

Which lymphatic vessel drains majority of the lymph from the different smaller lymphatic vessels in the body?

A

Thoracic duct

30
Q

lymph fluid from the lower extremities drain into which vessel?

A

Thoracic duct

31
Q

correct order of the flow of the lymph into and out of the lymph node?

A

afferent lymphatic vessels à lymph node à lymphatic tissue and sinuses à efferent lymphatic vessels

32
Q

the balance of fluid between the blood capillaries, interstitial spaces and lymphatic capillaries?

A

30L of fluid pass from the blood capillaries to the interstitial spaces per day. 90% of it returns to the blood while 10% enters the lymphatic system.

33
Q

T/F: The brain is devoid of lymphatic capillaries.

A

TRUE

34
Q

T/F: T cells remains stable in number but less functional in elderly.

A

TRUE

35
Q

T/F: Fewer onset of autoimmune diseases in elderly.

A

TRUE

36
Q

Passive immunization against tetanus toxin

A

utilizes immune serum obtained from a different animal than the host.

37
Q

The largest antibody in the blood is

A

IgM

38
Q

The antibody that can be detected in the breastmilk is

A

IgA

39
Q

basophils?

A

They are motile type of WBC circulating all throughout the blood.

40
Q

The macrophages found in the liver are called

A

Kupffer cells

41
Q

This refers to the ability to resist damage from various pathogens

A

Immunity

42
Q

This lymphatic fluid absorbed from the gastrointestinal lining is characterized as white due to its high fat and lipid content.

A

Chyle

43
Q

the movement of the lymph through the lymphatic vessels?

A

The contraction of the surrounding skeletal muscles facilitates in propelling the lymph.

44
Q

spleen is a graveyard of

A

Red Blood Cells

45
Q

infection of the genitalia can enlarge which lymph node

A

Inguinal nodes

46
Q

paired tonsils

A

Palatine

47
Q

lymphoid organ that degenerates as the person ages

A

Thymus

48
Q

antibody that can cross the placenta

A

50
Q

The cells responsible for the responses in cell-mediated immunity (T-cells) mature in the

A

Thymus

51
Q

T/F: WBC is capable of chemotaxis.

A

TRUE; They can attract more WBCs for further defense.

52
Q

Viral infections can

A

increase the number of lymphocytes because viruses can induce lymphocyte activation. On the other hand, bacteria induces neutrophil activation.
