Blood circulation

Function of white blood cells

1. blood clotting
2. fight pathogen

What is the main function of the red bloodcells?

1. to transpose oxygen
2. to transport oxygen
3. to transform oxygen

Name 2 parts of the circulatory system.

What blood cells are there?

What does the red colour mean? And the blue colour?

91% water
7% blood proteins
2% dissolved substances

1. Blood plasma
2. Bloodcells

3.1 Blood

Blood transports everything your body need 

              (heat, nutrients, oxygen, waste products)

Blood contains:

- blood plasma (Proteins- fibrinogen for clotting blood,

         water,                    carbon dioxide

         oxygen                  waste products

         nutrients

The heart

the heart is part of the systemic circulation.

It needs O2 (respiration) the coronary arteries provide O2 to the heart. 
The coronary veins brings CO2 back to the heart

What is the circulatory system?

1. Made up of the heart and blood vessels.
   
2. Blood vessel: tube through which blood travels
3. Blood stays in these blood vessels most of the time
4. Blood vessels are large and small.

Learning objectives 

• You can name three types of blood vessels with their features and functions.
  
• You can name arteries and veins in the human circulatory system.
  
• You can distinguish between the pulmonary and systemic circulation with their functions.

What is circulation?

Two kinds of circulation systems

1. Pulmonary circulation

2. Systemic circulation

Pulmonary circulation

1. heart - lungs - heart
2. Right side of the heart sends oxygen poor blood to lungs
3. Oxygen rich blood flows back to heart. 

Systemic circulation

1. heart - body - heart
2. Left side of the heart sends oxygen rich and glucose rich blood to body
3. CO2 and waste products get picked up and blood brings back to heart

3.4 Blood vessels (later 3.3)

3 types of blood vessels

arterie, capillarie, vein

Artery

From heart to organs

(red) transport O2

walls are: 
    - thick, firm, elastic

High blood pressure 

Capillaries

Release O2 into organs

Absorb Co2 into bloodstream

- one cell layer tick walls

- white bloodcells can go between the cells into the tissue

Veins

Transport CO2 from organs to the heart

- low bloodpressure

       thinner, less elastic

Includes valves

- The blood can flow in 1 direction

Formulate a question about the fragment you just watched, where the answer contains "Iron"

I still have a question about...

Use your notes to summarize the 2 types of circulation systems in your body.

What I learned in this lesson was....
