🔍 Key Concepts

• Difference between arterial and venous bleeding • Relationship between blood color and oxygen content • How blood pressure affects the way blood exits a damaged vessel

💭 Think About

• Think about which type of blood vessel carries blood away from the heart and under higher pressure. • Consider how higher pressure would change the pattern of bleeding at the wound site. • Recall which type of blood (oxygen-rich vs oxygen-poor) has a brighter red appearance.

✅ Before You Answer

• Identify which choices describe bright vs dark blood and relate that to oxygen-rich vs oxygen-poor blood. • Compare which answers describe steady flow vs spurting, and match that to high vs low pressure systems. • Before choosing, decide which vessel type (artery vs vein) is under higher pressure and carries oxygen-rich blood.
