Muscles make your body move by ________.

Contracting (and pulling bones toward them where they are connected)

100
What are the 2 main parts of your nervous system?
Brain and Nerves
100

What is the main purpose of your respiratory system?

Getting oxygen into your body, and sending carbon dioxide out 

100
What is the purpose of arteries?
They carry blood away from the heart
100
Where does mechanical digestion happen in your digestive system?
Mouth (teeth chewing food), stomach (churning food), a little bit in the small intestines (food is squished through)
200
What parts of your skeleton allow it to bend?
Joints
200

What is the purpose of the Nervous System?

It sends messages throughout your body

200
Which other body system does your respiratory system work closely with?
Cardiovascular system (your blood carries the oxygen and carbon dioxide from and to your lungs)
200

How do oxygen and nutrients get from your blood into the muscles where they are needed?

The walls of some blood vessels (capillaries) are so thin that oxygen & nutrients can go straight through them

200
Where does chemical digestion happen?
mouth (saliva), stomach (stomach acid), small intestines (bile and other enzymes)
300

What are the 2 main purposes of your skeleton?

Your skeleton supports your body/gives you structure and Protects your internal organs

300
What part of your brain is responsible for all of your senses, thinking, language, and voluntary movements?
Cerebrum
300

What pathway does air take when it enters your body (starting with the nose/mouth)?

Air comes in through the nose or mouth, travels down the trachea, into the bronchi, and finally reaches the alveoli

300
What is the purpose of a valve, and where are they found?
They make sure blood only flows forward; they're found in the heart and in your veins
300
Where are the nutrients in food absorbed?
small intestine
400
What's the difference between a ligament and a tendon?
Ligaments attach bones to other bones, and tendons attach muscles to bones.
400

What is happening in each section of your brain (frontal lobe, parietal lobe, temporal lobe, occipital lobe, cerebellum, brain stem) when you are eating a meal?

Frontal - sending messages to the muscles in your hands and arms to cut and pick up food, deciding which piece of food to eat next; Parietal - tasting the food that you eat; Temporal - smelling the food you're eating, having a conversation with the other people at the table; Occipital - seeing what you are eating; Cerebellum - hand/eye coordination as you use your silverware; Brainstem - breathing, heartbeat, etc.

400
What makes your lungs fill with air?
Your diaphragm contracts (moving downward), increasing the amount of space in your chest cavity. Since there is more space, air moves in to fill it up.
400

What is the name of the chambers where blood enters the heart? Why are their muscular walls thinner than the other chambers?

Atria (Right Atrium and Left Atrium) have thinner walls because they only have to push the blood a short distance; Ventricle walls are much thicker so that they can push blood throughout the entire body.

400
Where is water absorbed?
large intestine
500
Name a voluntary muscle and an involuntary muscle
Biceps (or triceps, or quads, or hamstrings, or any other skeletal muscles) are voluntary muscles; your heart (or diaphragm, or the muscles in your stomach, blood vessels, small intestine, etc.) are involuntary muscles
500

What is happening in each section of your brain (frontal lobe, parietal lobe, temporal lobe, occipital lobe, cerebellum, brain stem) when you are doing math homework?

Frontal - problem-solving to help you answer the questions, sending messages to the muscles in your hands and arms to move your pencil and push the buttons on your calculator; Parietal - reading the problems on the page and writing the answers; Temporal - remembering the tricks that Mrs. Ream taught you in class (keep, change, flip, etc.), maybe listening to music as you work; Occipital - seeing the problem on the page; Cerebellum - hand/eye coordination as you write; Brainstem - breathing, heartbeat, etc.

500
How does your brainstem know how fast you should be breathing?
It measures the amount of carbon dioxide in your blood. High carbon dioxide levels mean your cells are using lots of oxygen, so your brain signals your diaphragm to move faster.
500
Where does your heart send oxygen-poor blood?
To your lungs
500

Where (what organ) does the small intestine send the nutrients that it absorbs?

to the liver (via the blood)
