A

tough fibrous, inelastic
connective tissue that attaches
muscles to bones

31
Q

what are ligaments

A

tough, fibrous, elastic
connective tissue that attaches one bone to another at movable joints

32
Q

what does the regulatory system do

A

responds to changes in the environment/coordinates life activities

33
Q

what is the central nervous sytem made out of

A

brain and
nerve cord.

34
Q

what does the cerebrum do

A

its where the thinking occurs/ center for voluntary action

35
Q

what does the cerebellum do

A

used for balence/ coordination

36
Q

what does the medulla/brainstem do

A

tells heart to beat/ cant survive without

37
Q

what does the nerve/spinal cord do

A

relays info to & from the brain / center for reflex action

38
Q

what are hormones

A

chemical messengers that travel through the circulatory system/ a way to monitor what’s in ur body + make adjustments

39
Q

what does the endocrine system use to monitor the body

A

feedback

40
Q

why does the endocrine system use feedback

A

to maintain dynamic equilibrium + homeostasis

41
Q

what does the pancreas do

A

it releases 2 hormones (insulin and glucagon)

discruption of blood supply to a portion of the brain and that part becomes damaged

44
Q

what is goiter

A

an enlarged thyroid that results in a change in metabolic rate. This results from iodine deficiency

45
Q

Q

what are phagocytes

A

They engulf foreign
antigen and destroy them, you’re born with these

51
Q

what are lymphocytes

A

not born w these, only way to develop these are to be exposed to pathogens,

52
Q

what do lymphocytes do

A

they secrete antibodies that destroy/mark for destruction things with foreign antigens

53
Q

what are vaccinations used for

A

Vaccines are used to help develop lymphocytes using dead/weakened pathogens

Q

what are damages to the immune system

A

aging, stress, fatigue

A

an autoimmune disease in which the immune system attacks healthy cells

60
Q

what happens when you get organ transplants

A

The immune system will attack the organ, because of the different antigens.

61
Q

what are Immunosuppressant Drugs

A

Reduce the effectiveness of the immune system so that the organ will not be rejected

62
Q

what do Immunosuppressant Drugs do to your immune system

A

it reduces the immune systems ability to fight
other pathogens
