🔍 Key Concepts

• Arterial vs. venous vs. capillary bleeding – how they differ in color and flow pattern • The relationship between oxygen content and the color of the blood (bright vs. dark red) • How the heartbeat/pulse can affect the way blood leaves an artery

💭 Think About

• Which type of vessel (artery or vein) is under higher pressure and directly connected to the pumping action of the heart? How would that affect the way blood exits a wound? • Does blood that is rich in oxygen tend to appear brighter or darker? Match that to the likely color from an artery. • Think about which option best reflects blood being pushed out in rhythm with the heartbeat, rather than simply oozing or steadily flowing.

✅ Before You Answer

• Check which answer choice mentions bright vs. dark red and decide which is more consistent with oxygen-rich blood from an artery. • Check the pattern of flow described: is it in spurts/pulsing or a slow/steady flow? Which one better matches high pressure from the heart? • Eliminate any options that combine low-pressure flow patterns with features of high-oxygen arterial blood, or vice versa.
