AQA GCSE PE: Blood Vessels | The Structure & Functions of Arteries, Veins & Capillaries | AQA Paper 1

This video will detail the structure and functions of the blood vessels found in the human body, as it is a requirement to understand these. It is in hope that this video will help strengthen and consolidate your understanding of the blood vessels, which will prove pivotal not only for multiple choice questions, but questions where detail and depth is required.

What you need to know in summary:

Structure of arteries, capillaries and veins:

• Size/diameter
• Wall thickness
• Valves in veins.

How the structure of each blood vessel relates to the function:

• Carrying oxygenated/deoxygenated blood to/from the heart
• Gaseous exchange
• Blood pressure
• Redistribution of blood during exercise (vasoconstriction and vasodilation).

You also need to know the names of the arteries and the veins associated with blood entering and leaving the heart.

I have attached the AQA specification below where you can read about this.

Key terms: blood vessels, arteries, veins, capillaries, vasodilation, vasconstriction, blood flow, oxygenated blood, oxygen, deoxygenated blood, carbon dioxide, pulmonary artery, pulmonary vein, aorta, vena cava, alveoli and gaseous exchange.

As ever, if you require any assistance please leave a comment in the section below.
