32
Q

What function is carried out by your saliva?

A

It is chemically digesting the food.

33
Q

What is the main functions of the excretory system?

A

To remove waste from the body

34
Q

What is the interactions between the digestive system and the resiratroy?

A

To use the energy in food broken down by digestive system, the body needs oxygen obtained by the respiratory system

35
Q

Which structure filters wastes from the blood and regulates the amount of water in the body to maintain homeostasis?

37
Q

What type of neurons sent impulses to your muscles?

A

Motor

38
Q

What endocrine system disorder that could cause blood glucose levels to be higher than these levels at all times?

A

Diabetes

39
Q

Which sense provides her brain with this information?

A

Touch

40
Q

How would the endocrine system respond after a person digests a piece of fruit?

A

It would release more of the hormone that helps cells take glucose out of the body.

41
Q

What is the role of the nervous system?

A

to gather and respond to information

42
Q

What is the function of the cerebrum?

A

Where you think and problem solve

43
Q

What is the function of the cerebellum?

A

keeps track of body positionc

44
Q

What is the function of the brain to the spinal cord?

A

Connects the brain to the spinal cord

45
Q

What does the PNS do?

A

The PNS connects the CNS to the rest of the body. The PNS contains sensory and motor nerves. Sensory nerves get impulses to muscle. Motor nerves get information form the environment.

46
Q

What does the CNS do?

A

The CNS is made up of the spinal cord and the brain. The brain is like the command center of the body. The spinal cord allows the brain to communicate with the rest of the body.

47
Q

How are hormone levels controlled?

A

Hormone levels are controlled by the feedback mechanism which is a cycle of events in which information from one step controls or affects a previous step.
