Catalyst: Answer the following questions silently in your binder. Raise your hand if you have a question.

1. What would happen during digestion if the small intestine was damaged or not working?

2. What would happen during digestion if the salivary glands (which produce saliva) were damaged or not working?

3. What would happen if the kidneys were damaged (and you were not given dialysis)?

4. Why is it bad if your heart stops beating?

5. Why is it bad if you stop breathing?

FOCUS

9a.2 - I can synthesize how the respiratory and circulatory systems maintain homeostasis by drawing and

labeling diagrams of each working together.

9c.1 - I can describe the major parts of the endocrine system by explaining diabetes.

cellular respiration

Carbon dioxide(CO2)

Water(H2O)

ATP (energy)

Oxygen(O2)

Glucose

circulatory system

reactants products

blood vessels and heart; deliver nutrients and carry

away waste

What are the steps in circulation?

1. O2-poor blood from body enters right atrium (top right heart chamber)2. O2-poor blood pumped to right ventricle 3. O2-poor blood pumped through pulmonary artery to lungs 4. Gas exchange in lungs

a. blood releases CO2 b. O2 binds to hemoglobin on red blood cells

5. O2-rich blood goes through pulmonary vein to left atrium6. O2-rich blood pumped to left ventricle7. O2-rich blood pumped to body8. O2 is delivered to cells, blood picks up CO2 from cells

CFU: A bloody good story!In one paragraph, write a first person story as a blood drop moving through the circulatory system. Make sure to give

us updates on your O2 and CO2 content.

Bonus points if you can do it with a

character impersonation

Take my oxygen, will you?

lungs1. diaphragm contracts, pulling the lungs down2. air passes through:

1. nose or mouth2. trachea3. bronchi4. bronchioles5. alveoli

3. CO2 in blood enters alveoli through capillaries, O2 in alveoli enters blood through capillaries4. diaphragm relaxes, pushing air out

Play 60

Let’s play and collect some data

What are hormones? Can you give examples of any?

Hormone chemical message sent through bloodex.: insulin, adrenaline

Endocrine system

organs that release hormonesex.: pancreas, adrenal gland

What is diabetes?

Pancreas- monitors blood sugar- releases insulin to lower blood sugar

- releases glucagon to raise blood sugar

As we watch:1. What hormone raises your blood sugar?

2.What hormone lowers your blood sugar?

3. Why is it important to maintain homeostasis with your blood sugar levels?

4. What is diabetes?

Bringing it all together

1. At your tables, read the sample project for Beckerman style oatmeal. Highlight everything related to the

respiratory system in a 3rd color. Highlight everything related to the endocrine system in a 4th color.

2. You will be making your own mind map with no help this unit. The word homeostasis should go in the middle. Draw pictures of the organs we learned about, explain what they

do, and explain how they connect to homeostasis.

Exit SlipPut the following steps in order. Use them to draw a simple comic to explain what happens after eating.

- blood is oxygenated in alveoli of lungs- digest food- body cells release carbon dioxide into blood- pancreas releases insulin- blood travels to body through arteries and gives body cells oxygen through capillaries- increase blood sugar- body cells use oxygen to break down glucose for energy- blood travels back to heart through veins, then releases CO2 into the lungs- sugar enters body cells from blood, reducing blood sugar
