Q

Endocrine System

A

Controls over hormones; helps with metabolism and responds to stress and mood

27
Q

Excretory System

A

Removing wastes; by pissing (not pooping that goes with the digestive)

28
Q

Integumentary System

A

Protects the body from outside conditions; the skin is a example as it keeps you warm and regulates water loss

29
Q

Lymphatic System

A

To filter lymph in order to help keep the body away from viruses

Q

Reproductive System

A

Allows for people to reproduce and make babies

34
Q

Respiratory System

A

Helps us breathe; To take in oxygen and release it

Q

Cold Blooded

A

Switches between cold and hot

37
Q

Warm Blooded

A

regulates the temperature

38
Q

Negative Feedback

A

A condition cause something else to go on in order to equally balance the body out

39
Q

Positive Feedback

A

Intensifies the variable instead of responding

40
Q

Complement System

A

To help the actions of the immune system

41
Q

Mast Cell

A

type of cell that has a bunch of substance, upon spotting and pathogen is releases these substances to weaken the pathogen

42
Q

Macrophage

A

Cells that consume pathogens

43
Q

Cytotoxic T Cell

A

is a white blood cell that can destroy cells that have been infected, they do this by sending signals so the cells can preform apoptosis.

44
Q

Apoptosis

A

An action where a cell self destructs this can be due to a error with genetic coding or if a Cytotoxic T Cell sends signals to make it preform the action

45
Q

Helper T Cells

A

Help send signals to Cytotoxic T Cells

46
Q

Q

Antibodies

A

Proteins that are in a Y shape that recognizes foreign substances and neutralize them

50
Q

Memory B Cells

A

Cells that activate B Cells to fight that there are infected cells in the body

51
Q

Memory T Cells

A

Cells that activate T Cells to fight that there are infected cells in the body

52
Q

Dependant Variable

A

Whats being collected (ex: pulse rate)

53
Q
