What causes the red color in red blood cells? This can transport oxygen.

1. Glucose
2. Carbon dioxide
3. Glycogen
4. Haemoglobin

Which blood vessels have a low blood pressure?

1. Capillaries and veins
2. Veins
3. Capillaries
4. Arteries

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

Where are a wasp's respiratory organs located?

1. Head
2. Thorax
3. Whole body

In which part of the gills does the countercurrent exchange system take place?

1. Gill arch
2. Gill cover
3. Lamellae
4. None of these answers are correct

What color is the blood of mosquitoes and other insects?

1. Dark blue
2. Bright red
3. Light yellow

How does blood flow through your body?

1. heart-lungs-heart-organs
2. heart-lungs-organs-heart
3. heart-organs-lungs-heart

The blood of insects

Does not contain:

- oxygen

- carbon dioxide

Does contain:

- nutrients

- waste products

Open circulatory system = blood flows through vessels and oozes out from blood vessels to flow out into the body

The blood of fish

Closed circulatory system = blood flows through blood vessels while passing the heart

Single circulatory system = blood passes the heart only once per circuit when flowing through the body

(humans have a double cs!)

Double circulatory system

Vascular bundles

Xylem vessels = vessels that transport water and minerals from the roots upwards

Phloem vessels = vessels that transport water with dissolved nutrients throughout the entire plant

How does water flow upwards?

1. Suction force = as a result of evaporation of water from the leaves, water is sucked up through the xylem vessels.

2. Root pressure = so much water comes into the xylem vessels in the roots that it is pressed upwards

3. Capillary action = water flowing upwards within the narrow xylem vessels

Wat?	Maken: 13.3 opdrachten 11 t/m 14, 19 en 21
Hoe?	In je (online) boek. Werkbladopdrachten maak je in je schrift. Keuze: fluisterend overleggen of muziek luisteren.
Hulp?	Steek je hand op. Als je geen muziek luistert mag je ook zacht overleggen met je buurman/buurvrouw.
Tijd?	10 minuten
Klaar?	Goedzo! Nu mag je aan de slag voor een ander vak!
Opbrengst	Als je klaar bent heb je je huiswerk af! Nu weet je meer over de bloedsomloop van insecten en vissen!

What?	Make: 13.3 assignments 4-9, 12-18
How?	In your (online) workbook. You are allowed to consult with your neighbour in a whisper.
Help?	First consult with your neighbour. Then raise your hand.
Time?	10 minutes
Finished?	Check your answers. Now make a summary of 13.1 and 13.2.
