Topic 3

ORGANIZING THE WORLD

§3.3 The Heart

p. 122-125

§3.3  - Learning goals

I can....

• describe how the electrical signal travels through the heart and causes the three phases of the cardiac cycle.
• describe how blood pressure is created by the heart.
• follow the path of the blood through the circulatory system.
• name the arteries and veins based on the organs they are connected to.
• describe the role of the valves in the heart and how they create the heart tones.
• describe how blockages in the circulatory system can cause major problems for the body.  

p. 122-125

§3.3  - Key words

• Heart
• Atrium
• Ventricles
• Portal vein
• Coronary Arteries
• Clots
• Stroke
• Heart attack

p. 122-125

Aorta

pulmonary artery

pulmonary vein

vena cava

right atrium

right ventricle

left atrium

left ventricle

tricuspid valve

aortic  valve

mitral valve

pulmonary valve

septum

apex

§3.3  - The Phases of the cardiac 

cycle

• Atria contract → first peak, before the large peak

Pushes blood into the ventricles

• Ventricles contract → large peak

Pushes blood out of the heart

• Rest → last peak, after the large peak

Muscle relaxes, blood flows into the atria

p. 122-125

§3.3  - What controls it.

Nerve cells in the right atrium produce electrical signals

Signal reaches both atria → contract

Signal runs down the wall and up the sides → ventricles contract → highest blood pressure

Moment without signal → rest → lowest blood pressure

p. 122-125

THE MAJOR BLOODVESSELS:

1. Carotid vein
   
2. Pulmonary artery
3.  Superior vena cava
   
4. Inferior vena cava
5. Hepatic vein
6. Hepatic portal vein
7. Renal vein
8. Femoral vein
9. Carotid artery
10. Pulmonary vein
11.  Aorta
12. Mesenteric artery
13. Renal artery
14. Femoral artery

You take a paracetamol for a headache. (intestines - brain)

1. intestines
2. hepatic portal vein
3. liver
4. hepatic vein
5. inferior vena cava
6. right atrium
7. right ventricle
8. pulmonary artery
9. lungs
10. pulmonary vein
11. left atrium
12. left ventricle
13. aorta
14. carotid artery
15. brain

§3.3  - Problems with the heart

Clots form and block the vessel

In the coronary artery → heart attack

In the brain → stroke

p. 122-125

HW for next time:

• Complete the exercise of Topic 3.3 (p.126-133)

Prepare for a review lesson:

• Read TB §3.1-§3.3
• Study §3.1-§3.3 lessonups & notes
• Study the glossaries of §3.1-§3.3
