When we did the Pump it Up lab, why was it necessary for your pulse/heart rate to increase with more activity?

Heart works harder to send more oxygen & nutrients to cells to make energy

During the skin sensitivity lab, what part of the body did we find was the most sensitive and why?

The fingertips because we use them the most to get information

What would happen if the large intestine stopped working within the digestive tract?

Water would not be absorbed and you would have diarrhea

voluntary AND involuntary because we can choose to open or close our eyes

The Circulatory/Cardiovascular System...

Moves blood, nutrients, and waste throughout the body

The Lymphatic System...

Makes white blood cells & protects body against foreign invaders

You fall asleep in science during a lab. The teacher slaps table to wake you and you jolt awake. Stimulus/response?

Stimulus: The slap on the desk. Response: You’re awake.

The MAIN purpose of sexual reproduction is to...

Increase the diversity of traits within a species

In the digestive system, an accessory organ is one that...

Food does not travel through, but provides support to the digestive organs

During our Lung capacity lab, how would an athlete’s lung capacity differ from a non-athlete’s?

Athlete has larger lung capacity b/c they use lungs more & need more oxygen

During our Catch Me if You Can lab, why didn’t any students have a reaction time of ZERO?

Reaction time of 0 is impossible b/c the message needs time to travel

Theh Integumentary System...

Protects body, regulates temperature, provides sense of touch

During the skin sensitivity lab, what part of the body did we find was the most sensitive and why?
The fingertips because they have fingerprints that sense temperature
The back of the hand because it has the least fat so we can feel more
The fingertips because we use them the most to get information
The neck because it has lots of muscles in it
6
What type of cell is most important for carrying oxygen throughout the body?

White blood cell
Red blood cell
Nerve cell
7
What would happen if the large intestine stopped working within the digestive tract?
Water would not be absorbed and you would have diarrhea
Nutrients wouldn’t be absorbed and you would be hungry
Food would not be chemically digested & you couldn’t get nutrients from it
Food wouldn't be mechanically digested & you couldn’t get nutrients from it
8

voluntary because we always choose when we blink
voluntary AND involuntary because we can choose to open or close our eyes
neither voluntary or involuntary
involuntary because we don't try to blink but do it anyway

Where does MOST nutrient absorption occur within the digestive system?
Large intestine
Mouth
Stomach
Small intestine
10
The Circulatory/Cardiovascular System...
Sends messages throughout the body
Gives the body support & shape, movement, & makes red blood cells
Moves blood, nutrients, and waste throughout the body
Makes white blood cells & protects body against foreign invaders
11
The Lymphatic System...
Filters blood and removes waste
Breaks down food into nutrients for body
Makes white blood cells & protects body against foreign invaders
Supplies the blood with oxygen and removes carbon dioxide waste from body
12

14
In the digestive system, an accessory organ is one that...
Food travels through
Provides decoration for other digestive organs
Attaches to other organs but does not provide any purpose
Food does not travel through, but provides support to the digestive organs
15
During our Lung capacity lab, how would an athlete’s lung capacity differ from a non-athlete’s?
Athlete has a larger lung capacity b/c they don’t use their lungs as much
Athlete has larger lung capacity b/c they use lungs more & need more oxygen
Athlete has a smaller lung capacity b/c they don’t use their lungs as much
Athlete has same sized lung capacity b/c they don’t do anything differently
16
During our Catch Me if You Can lab, why didn’t any students have a reaction time of ZERO?
Reaction time of 0 is impossible b/c the message needs time to travel
No one was lucky enough to get a zero for a reaction time
The ruler didn’t have a zero centimeter mark on it
Because the teacher said you weren’t allowed to have a reaction time of 0
17
Theh Integumentary System...
Protects body, regulates temperature, provides sense of touch
