1. UNIT 3 The Circulatory System Mr. Scisly 6th Grade Health

2. LESSON #1 WARM-UP ACTIVITY 1) What is the most important muscle in the body? Why? 2) What does the Circulatory System do?

3. LESSON #1 GOALS
Today’s goal is to understand the function of the circulatory and the importance of the heart.

5. Circulatory System

7. Preview Video Questions
1) What does the blood transport that our body needs?
2) What does the body transport that our body needs to get rid of?
3) What result from eating a diet high in fat?
4) How does and an athlete’s heart differ from a non-athlete’s heart?

8. Circulatory System What does it do?
It carries needed substances to cells and carries waste products away from cells.

9. Lesson #1 Guided Practice
Work on the “Body’s Transportation System” Handout in your group.

10. LESSON #2 WARM-UP ACTIVITY
Pre-Test:
ON YOUR OWN, try to label the parts of the heart on the worksheet using the word bank.

11. LESSON #2 GOALS
By the end of the period today, you will be able to label a heart diagram and also the understand the functions of various parts of the heart. (Atrium, Ventricle, Septum, Valve, Pacemaker)

12. What Is the Heart?
A Hollow Muscular organ that pumps blood throughout the body.

14. The Parts of the Heart
Septum- Thick muscular wall that separates the right and left sides of the heart
Atrium- Two upper collecting chambers of the heart
Ventricles- Two lower pumping chambers of the heart
Valve- A flap of tissue that prevents blood from flowing backward
Pacemaker- Located in the right atrium and sends out signals that make the heart muscle contract

17. Lesson #2 Guided Practice
In your group, check your diagram of the heart and see if you labeled all of the parts correctly. If some parts are incorrect, fix it.

18. LESSON #3 WARM-UP ACTIVITY
ON YOUR OWN, answer the following question.
The blood travels through the body through two loops. The right and left sides of the heart are separate pumps. Where do they pump the blood to?

19. Today’s goal is to understand the path of blood through the body.
LESSON #3 Goals
Today’s goal is to understand the path of blood through the body.
By the end of the period today, you will be able to label a diagram to demonstrate your understanding of the path of blood.

21. The Path of Blood Two Types of Circulation 1) Pulmonary Circulation
2) Systemic Circulation

22. Pulmonary Circulation
Vena Cava
Right Atrium
Tricuspid Valve
Right Ventricle
Pulmonary Arteries
Lungs
Pulmonary Veins
Bicuspid Valve

23. Systemic Circulation Left Atrium Bicuspid Valve Left Ventricle Aorta
Smaller and Smaller Arteries
Capillaries
Veins
Vena Cava
Bicuspid Valve

25. Lesson #3 Guided Practice
In your group, label the chart detailing the Path of Blood.

27. LESSON #4 WARM-UP ACTIVITY
In your group, label the functions of the Right Atrium, Left Atrium, Right Ventricle, and Left Ventricle in your packet.

28. THE PATH OF BLOOD
THROUGH THE BODY

29. Review the Path of Blood
LESSON #4 Goals
Today we will complete the following tasks:
Review the Path of Blood
Demonstrate an understanding of the difference between the three types of blood vessels

30. Chambers of the Heart
Right Atrium- Receives blood from the body. The blood is low in oxygen and high in waste products.
Right Ventricle- Pumps blood with low-oxygen to the lungs
Left Atrium- Receives oxygen-rich blood from the lungs
Left Ventricle- Pumps blood with high oxygen to all parts of the body

32. Blood Vessels
3 Types
Arteries
2) Veins
3) Capillaries

33. Arteries Arteries- Blood vessels that carry blood away from heart
Aorta- The largest blood vessel in the body, carries blood from the left ventricle to the body
Coronary Arteries- Blood vessels that carry blood to the heart itself

34. Pulse
Heartbeats per minute

35. Veins Veins- Blood vessels that carry blood back to the heart
Vena Cava- Largest vein in the body, returns oxygen poor blood to the heart

36. Capillaries
Capillaries- Blood vessels where materials are exchanged between the blood and body’s cells

37. Sphygmomanometer
An instrument used to measure blood pressure.

38. Lesson #4 Guided Practice
EXIT SLIP
On your note card, explain the difference between veins, capillaries, and arteries.
**You may not use your books or notes!

39. LESSON #5 WARM-UP ACTIVITY
In your groups, answer the following questions:
What is blood pressure a measure of?
What is normal blood pressure?
What is a sphygmomanometer?

40. LESSON #5 Goals
Our goal today is to be able to identify and define the parts of blood and also some various diseases of the circulatory system.

41. Plasma Red Blood Cells Platelets White Blood Cells
4 Components of Blood
Plasma
Red Blood Cells
Platelets
White Blood Cells

42. Plasma
Liquid Part of the Blood

43. Take up oxygen and deliver it to cells
Red Blood Cells
Take up oxygen and deliver it to cells

44. The body’s disease fighters
White Blood Cells
The body’s disease fighters

45. Play an important role in blood clots.
Platelets
Play an important role in blood clots.

46. Lesson #5 Guided Practice
In your groups, use your book to find the definitions for atherosclerosis, hypertension, and heart attack. In addition, come up with three ways to prevent heart problems.
