Answer 1

Correct Answer: Blood is red

Rationale:

Bleeding from an artery is characterized by bright red blood. This is due to the high oxygen content in arterial blood, which gives it a bright red color.
Arterial bleeding is often more severe and can spurt out with each heartbeat, making it more dangerous and requiring immediate medical attention.

Explanation of Other Options:

Blood is purple

Rationale: Blood that appears purple or dark red is typically venous blood. Venous blood has lower oxygen content compared to arterial blood, which causes its darker color.

Bleeding is continuous

Rationale: Continuous bleeding is more characteristic of venous bleeding. In arterial bleeding, the blood typically spurts out in rhythm with the heartbeat, rather than flowing continuously.

Bleeding is intermittent

Rationale: While arterial bleeding can appear intermittent due to spurting, it is more accurately described by the bright red color of the blood. Intermittent bleeding can also occur in various types of wounds and is not specific to arterial bleeding.

Conclusion:

Among the given options, "Blood is red" is the most accurate descriptor of arterial bleeding. The bright red color is due to the high oxygen content in arterial blood, which distinguishes it from venous blood that is darker and less oxygenated.
