Immune System Flashcards

1
Q

What is the adaptive immune defense

A

Innate immunity fails,
Depends on t and B lymphocytes to act,
They have specific antigen receptors which help distinguish our cells to foreign invaders. Which helps kill pathogens, bacteria, parasites, etc.

Q

What is contained in lymph nodes?

A

Macrophages and lymphocytes

17
Q

Lymph node function B

A

Filters lymph throughout body

18
Q

What’s the purpose of immunity?

A

To kill or remove foreign invaders in the body

19
Q

What are the branches and names of our immune system?

A

There’s 2 branches and the names are innate and adaptive.

20
Q

What is innate immunity?

A

Innate use chemical and physical barriers to protect.

21
Q

What is the physical barrier in innate system?

A

Our skin, it’s tough and protects us. But exfoliation help keep microbes away.

22
Q

What does the mucous membranes do?

A

The membrane cilia sweeps pathogens trapped within mucus

23
Q

What is the chemical barriers

A

Our sebaceous glands secrete acid that weakens and kills bacteria

24
Q

What does acid in the stomach do?

A

The chemicals in the stomach is acidic and kills bacteria.

25
Q

What is the function of inflammatory response?

A

To send neutrophils and macrophages to engulf pathogens

26
Q

What are the symptoms of inflammatory response?

A

Redness, swelling , heat, and pain!

27
Q

What does Wbc(white blood cells do) in the inflammatory response?

A

Release neutrophils,
Keep infections localized,

28
Q

What are protective proteins and function?

A

They are proteins designated with letters and help amplify the inflammatory response..

Some bind to mast cells and trigger histamines,

Others form the Membrane attack complex

29
Q

How many adaptive immunity pathways and what are they

A

2 pathways
Cell meditated immunity -t cells
Antibody(humoral) -b cells

30
Q

Antibody mediated immunity

A

Antigen binds on BCR on one specific cell, B cell produce clones of identical B cells for that specific antigen

Many B cells become plasma producing large numbers of antibodies l,

Other B cells become memory cells that remember antigen.

31
Q

What is an antibody structure

A

Y shaped Monomers some with diners, with constant and variable regions.
Where antigens binds. Match and fit like a lock and key

32
Q

Function of antibodies?

A

Neutralization and immune complex

33
Q

What are the classes of antibodies

A

igA
igD
IgE
IgG
Igm
