Slide 1 - Tekstslide

What are we going to learn today?

Today we will learn:

Which blood vessels there are.

How they flow through our body.

Slide 2 - Tekstslide

Blood vessels

Blood flows through 3 different blood vessels:

- Arteries

Flows away from the heart.

- Capillaries

Flow in between cells.

- Veins

Goes back to the heart.

Slide 3 - Tekstslide

Arteries

Have a very thick and elastic outer layer.

Your heartbeat is also being brought over through the arteries.

Blood flows very quickly here.

Slide 4 - Tekstslide

Capillaries

Capillaries are very thin; it's walls are only 1 cell thick. This makes transport of O2 and CO2 easier. There is always a capillary nearby a living cell.

Slide 5 - Tekstslide

Veins

Blood vessels that are thinner than the arteries. Inside the veins are valves that make sure blood doesn't flow back down because blood pressure is so low.

Slide 6 - Tekstslide

Blood pressure in blood vessels

Slide 7 - Tekstslide

Homework for next lesson

You can start working on exercise 1, 2 and 10. If you are finished early with them you can make the other exercises as well. But that won't be homework.

Today we will learn:

Which blood vessels there are.

How they flow through our body.

What the names of our blood vessels are.

Slide 10 - Tekstslide

Double circulatory system

Our circulatory system is a double looped system; per round trip through the body it passes the heart twice.

Pulmonary circulation: From the heart to the lungs and back.

Systemic circulation: From the heart to all your organs and back.
