bacteria?
You may vomit to rid your body of the toxic material
4.
Describe two examples of a response-to-stimulus situation?
Squinting when bright
lights are turned on, shivering in the cold, sweating in the heat,increased heart rate and
increases respiration rate in response to body’s oxygen needs, covering ears due to loud
noises, jumping when the fire alarm goes off, red warm skin due to an infected cut, etc.
answers will vary

Circulatory and nervous

Digestive

your body can
use
Circulatory and
muscular systems
Circulatory
Circulates
nutrients to all
body cells and
pick up wastes
from cells
Respiratory and
muscular systems
Nervous
Coordinates the

body
Integumentary
stimulus.
WHY ARE THEY
BEST FRIENDS
Both interact to
allow movement of
body
Works with
circulatory system
to regulate body
temp, gathers info
about environment
for nervous sytem
Circulatory system
absorbs nutrients
and carries them
thru out the body,
muscles move food
thru the digestive
system
Respiratory system
brings O2 into body
so circulatory sys
can distribute, also
releases CO2,
muscles line the
blood vessels
Integumentary sys
gathers info about
the environment
and sends it to the
brain
Which body system coordinates all body functions and actions? Nervous System
7.
How might your body respond if you had an infection such as strep throat?
Your throat may become red, inflamed, and sore. White blood cell count may increase, you
may develop a fever
8.
When your body is preparing to “fight or flight” what changes might you experience?
Adrenaline is released by the adrenal glands. Increased heart rate, respiration rate, and
blood pressure. Your senses become more acute (very alert) and your muscles taunt.
9.
Indicate if the following are examples of Internal (I) or External (E) stimuli.
feeling hungry
I
feeling heat from a flame E
stepping on a rock E
low blood sugar levels
I
low blood oxygen levels I
fire alarm
E
you salivate when you smell cookies cooking E
tickle in your throat I
lack of food E
lack of water E
10.
Indicate if the following are examples of stimuli (S) or a response (R).
sweating
R
increased blood pressure R
increase insulin levels
R
shivering
R
feeling thirsty
goose bumps
S
R
11.
What force do your veins have to overcome to push your blood back to your heart?
Veins have to exert a force strong enough to overcome the force of gravity
12.
Describe how the respiratory and circulatory systems work together to exchange
gases in your body.
The respiratory system brings air into the body when you inhale
and fills the alveoli in the lungs. The alveoli are surrounded by capillaries. Oxygen in the
alveoli enters the blood stream thru the capillary walls. The capillaries release carbon
dioxide into the alveoli to be released when you exhale.
