Structure and function of arteries
high / low / elastic / plastic / muscle / nerve / narrow / wide
- Arteries are large and carry blood at a very pressure.
- Artery walls have a thick middle layer, containing both muscle and tissue.
- The tissue provides strength, and allows the arteries to direct blood flow.
- The tissue allows the arteries to stretch and recoil.
- Compared to their walls, arteries have a relatively lumen, which keeps the blood pressure high.
|
Structure and function of capillaries
high / low / waste / one / exchange / diffusion / permeable / wide
- Capillaries are the smallest of the three blood vessels.
- The role of capillaries is to nutrients and products with the tissues.
- Capillary walls are , meaning substances are able to move through them.
- Their walls are also only cell thick which means a short distance for .
- Capillaries carry blood at a pressure and have a lower rate of flow than arteries.

Which of the following substances are nutrients that are exchanged between the blood in the capillaries and the body tissues?
(Select all that apply)
Amino acids
Carbon dioxide
Glucose
Urea
Proteins

Which of the following substances are waste products that are exchanged between the blood in the capillaries, and the body tissues?
(Select all that apply)
Carbon dioxide
Urea
Amino acids
Oxygen
Glucose
Proteins

Structure and function of veins
higher / lower / thin / thick / heart / wide / small / valves
- The role of veins is to carry blood from the body (or lungs) back to the .
- Veins are a similar size to arteries, but they have relatively walls and a relatively lumen
- This is because they carry blood at a much pressure.
- Veins also contain to prevent the blood from flowing backwards.

1.4 litres of blood passes through an artery in 7 minutes.
What is the rate of blood flow in millilitres per minute?
ml/min

Blood is flowing through a vein at a rate of 37 ml/min.
How long will it take for 407 ml of blood flow through the vessel? Give your answer in minutes.
minutes

Capillaries
Arteries
Veins
