Slide 7 - Quiz

Blood vessels
Arteries = blood vessels with thick, muscular walls that transport blood from the heart to the organs 

Capillaries = very small blood vessels

Veins = blood vessels that transport blood from the organs back to the heart
- Valves = prevent blood from flowing back; they are present in many veins and in and around the heart

Slide 8 - Diapositive

Blood supply for the heart

Coronary arteries = arteries around the heart

Coronary veins = veins that transport oxygen-poor blood from the heart to a vena cava


Slide 9 - Diapositive

pulmonary circulation: 
  • heart - lungs - heart
  • absorb oxygen, release carbon dioxide 

systemic circulation: 
  • heart - body - heart
  • release oxygen, absorb carbon dioxide
.

Slide 14 - Quiz

8.4 Your blood circulation
You will learn what types of blood vessels you have and how blood flows through your body.

You will learn what blood pressure is and how to measure it.

Slide 15 - Diapositive

Blood pressure
= force with which blood pushes against the walls of blood vessels

Healthy blood pressure for young people = around 110/70 millimetre of mercury

Systolic pressure = arises when the ventricles contract

Diastolic pressure = during heartbeat pause

Slide 16 - Diapositive

Does each organ get the same amount of blood every time?
Heartrate at rest: 70 bpm
Heartrate during excercise: over 200 bpm

ventricles pump 70 ml everytime
