Q

What is the direction of Fluid movement between arterioles, venues, blood capillaries, lymphatic vessels and tissues?

A

fluid moves from arterioles to blood capillaries and then into the tissues. the blood capillaries deliver more fluid to the tissues than they can carry away via the venues. the excess fluid in tissues returns to the bloodstream through lymphatic vessels.

17
Q

What is innate immunity

A

firstline of defence
born with it
responds to all foreign antigens
involved physical barriers

18
Q

what are the 7 components that make up innate response?

A 
physical barriers 
fever
inflammation 
complement 
phagocytes 
immune surveillance 
interferons
19
Q

Which components of innate immunity keeps hazardous organisms and materials outside the body?

A

Physical barriers such as skin and mucous membrane

20
Q

Which are the 2 phagocytes which play a role in innate immunity?

A

Neutrophils

Macrophages

21
Q

Immune surveillance continuously involves monitoring of peripheral tissues by which type of cells?

A

NK cells (natural killers)

22
Q

NK cells release…….

A

Perforin

23
Q

what is perofin?

A

Perofin creates pores in the plasma membrane of abnormal cells, preventing the abnormal cell from maintaining homeostasis

24
Q

What is the name of a small protein that is released by activated lymphocytes and macrophages and by our tissue cells that are infected with viruses?

A

Interferons

25
Q

What is the name of the proteins that is found in the plasma part blood and this helps to kill pathogens and enhance phagocytosis and inflammation?

A

complement

26
Q

Adaptive Immunity develops after birth as a results of……

A

Exposure to specific antigens

27
Q

What does adaptive immunity do?

A

Adaptive immunity protects the body against further attacks by the same type of disease causing pathogens

28
Q

4 Characteristics of Adaptive immunity

A
  1. Specificity
  2. Versatility
  3. Tolerance
  4. Memory
29
Q

Adaptive immunity involves…..

A

T and B cells

30
Q

name the two types of adaptive immunity?

A

cell mediated immunity

antibody mediated immunity

31
Q

Cell mediated does?

A

cell mediated defends the body against abnormal cells and cells with internal pathogen viruses

32
Q

Antibody- mediated does?

A

Antibody mediated defends the body against antigens and pathogens in body fluid

33
Q

What do B cells do for Adaptive Immunity?

A

B cells play an important role in adaptive immunity. B cells differentiate into plasma cells produce and secrete antibodies

34
Q

What are the four types of T cells?

A

Cytotoxic T cells
Helper T cells
Regulatory T cells
Memory T cells

35
Q

Memory?

A

responds to a previously encountered antigen

36
Q

Cytotoxic?

A

Attack foreign cells or body cells infected by viruses

37
Q

Helper

A

Stimulate the activation and function of T and B cells

38
Q

Regulatory?

A

Moderate activity of T and B cells

39
Q

What is an Antibody?

A

A protein produced by plasma cells binds to a specific antigen and promotes its destruction to removal

40
Q

Characteristics Primary

A

Moderate lib production

slow to start

41
Q

Secondary characteristics?

A

high lib production

starts immediately
