Unit: Staying Alive

Topic: Circulatory system

Lesson outline:

introduction by teacher

1 interactive video's about 15min incl MCquestions.

Remainder of the time: HW (see last slide)

Aims:

- Outline and label the double circulatory system

- Describe the parts of the heart and their functions

- Describe three types of blood cells and link their form to the functions

- Explain the relationship between exercise and heart rate

Use this image (and pg 72 in the textbook) to complete page 25 in the booklet

The double circulatory system:

PULMONARY CIRCULATION

SYSTEMIC CIRCULATION

Form (describe)

Function (explain)

1. 1.arterie 2. vein 3. capillary
2. 1. capillary 2. arterie 3. vein
3. 1. arterie 2. capillary 3 vein.
4. all answers are wrong

Which statement is true

1. A has the lowest blood pressure
2. B has the lowest blood pressure
3. C has the lowest blood pressure
4. B has the highest blood pressure

00:25

recall cell respiration

1. carbon dioxide + water -> glucose + oxygen
2. glucose + oxygen -> carbon dioxide + water

00:48

Learning Tips:

Make sure you have your notebook open, ready to take notes while watching this video.

You also need to open your Science Bio booklet and your textbook to check for understanding while watching the video.

01:25

Note:

1. The RIGHT side of the heart in the image is really the LEFT side of the heart.
2. The LEFT side of the heart is colored RED.
3. Blood enters the heart through the RIGHT atrium
   

01:46

Note:

We focus on the

form and function of the blood cells and the heart

in this unit.

02:16

Function of white blood cells

1. blood clotting
2. fight pathogen

03:12

VEINS are blood vessels that RETURN deoxygenated blood to the heart.

Ex. vena cava

ARTERIES are blood vessels that carry OXYGENATED blood away from the heart to the tissues and organs. Ex. aorta

(find these examples in your book!)

Exceptions to this rule:

pulmonary artery brings DEOXYGENATED blood away from the heart

pulmonary vein return OXYGENATED blood to the heart from the lungs.

04:07

Use pg 73 in your textbook. How many valves does the heart have?

1. 1
2. 2
3. 3
4. 4

04:58

what is the name of this process in the alveoli of the lungs?

1. respiration
2. inhalation
3. gas exchange
4. breathing

06:33

Note:

The remainder of the video is about the effect of exercise on the heart rate. This is information you might need for your criterion B task (design investigation that influences the HR and breathing rate)

02:16

Function of platelets

1. transport oxygen
2. blood clotting
3. transport water vapour
4. all of the above

Review the aims of this lesson and write down any questions you have on the next slide:

What I do not understand / questions I have about the content are:

Homework for next lesson

1. RSQ pg 78-79.  Choose 3 questions from Q 1-6 on pg 79.
2. Complete pages in the booklet on the circulatory system.
   
3. Chapter 3: End of section Questions page 82 and 83. Choose at least 5 questions from Q 1-11 (basic) or Q12-20 (extension).
