1. 30.1 Circulatory Functions
Set up Cornell Notes on pg. 73
Topic: 30.1 Circulatory Functions
Essential Question(s):
How do the respiratory and circulatory systems help maintain homeostasis in the body?
Arteries and veins are equally distributed throughout the body. How does this arrangement help to maintain the functions of each cell?
30.1 Circulatory Functions
2.1 Atoms, Ions, and Molecules

2. How does your heartbeat and breathing rates change as you go from a walk to a run?
In your experience, what factors may have interfered, making your breathing more difficult?

3. How does your heartbeat and breathing rates change as you go from a walk to a run?
They increase.
2) In your experience, what factors may have interfered, making your breathing more difficult?
Being out of shape High Altitude
Asthma Extremely Hot/Cold weather
Allergies
Respiratory infection
Second-hand smoke or because you ARE a smoker
Pollution
Chemical fumes
disease

4. KEY CONCEPT The respiratory and circulatory systems bring oxygen and nutrients to the cells.

5. brings supplies to cells carries away wastes
The respiratory and circulatory systems work together to maintain homeostasis.
The circulatory system transports blood and other materials to and from cells
brings supplies to cells
carries away wastes
separates oxygen-poor and oxygen-rich blood
Oxygen-poor blood
Oxygen-rich blood

6. There are three major functions of the circulatory system.
1) transporting blood, gases, water, and nutrients to cells
2) collecting waste materials (CO2)
3) maintaining body temperature

7. On pg. 72 create a bubble map of the Circulatory System
arteries
Pg in book
veins
Circulatory System
Red blood cells
hemoglobin
capillaries
heart
You need a description and picture for each

8. heart pumps blood throughout body
The system includes :
heart pumps blood throughout body
arteries move blood away from heart
Oxygen-rich blood
veins move blood back to the heart
Oxygen-poor blood
capillaries get blood to and from tissues
*Where gas, water, and nutrient exchange occur
Blood Vessels

9. red blood cells- pick up oxygen in the lungs and delivers it to all the body cells; picks up CO2
O2 binds to hemoglobin- gives blood its reddish color
Blood becomes bright red only when it absorbs oxygen

10. Video Notes
Add information to your bubble map from the video.
You need to add AT LEAST 2 more pieces of information to each part of the bubble map

11. Capillaries
Bronchi and Bronchioles

12. How does the respiratory and circulatory system interact?
Think: What does the respiratory system bring into your body?
How does the circulatory system distribute that product?
What waste product does the blood pick up from the cells?
How does our body get rid of that waste?

13. The lungs bring oxygen into the body
How does the respiratory and circulatory system interact?
The lungs bring oxygen into the body
the circulatory system (blood stream) carries that oxygen to all of the body’s cells.
The blood stream also picks up cells’ waste (carbon dioxide)
expels that waste as carbon dioxide when we exhale (breathe out).
