21
Q

whats Metastasis?

A

Spread of cancer cells via the lymphatic system

22
Q

whats the Immune System made up of?

A

specialized cells and organs

23
Q

whats the immune systems function?

A

Provides protection against bacterial and viral infections, destroys cancer cells and foreign substances

24
Q

what happens if immune system is weak?

A

the body’s ability to defend itself also weakens and

pathogens grow and flourish in the body.

25
Q

whats an antigen?

A

A foreign substance

examples: Bacteria, virus, allergens

26
Q

whats an antibody and its function?

A
  • What body produces in response to antigen

- it protects against disease

27
Q

whats immune response?

A

the body’s reaction to antigen exposure and the

body’s attempt to keep us free from disease.

28
Q

whats biological immunity?

A

Protection from disease/Body’s ability to resist infection

29
Q

Bone Marrow location and functions?

A
  • located in the lymphatic system structures

- Provide a specific immune response to infectious diseases and Produce B and T cells

30
Q

B cell location and function?

A
  • located in the in bone marrow

- Produce antibodies against an antige

31
Q

T Cells location and function?

A
  • located in the thymus gland

- attack the antigens

32
Q

whats Nonspecific Immunity?

A

Antigen that Invades the Body, mobilize the lymphatic system causing a Inflammatory Respons

33
Q

whats specific Immunity?

A

were Body has previously encountered the antigen

Immune system remembers the antigen

34
Q

Natural Passive immunity ?

A

From mother to child before birth/through breast milk

35
Q

Natural Active/Acquired immunity?

A

Develop antibodies during an actual attack of infectious disease

36
Q

Artificial/Acquired Passive immunity?
