Blood Vessels and Pulse

Q. Why an injection is administered in a vein and not in an artery?

1. Veins have valves that prevent backflow of blood.
2. Pressure inside arteries is high and puncture will lead to a lot of blood loss.
3. Veins carry oxygen-rich blood from all parts of the body to the heart.
4. Arteries carry carbon dioxide-rich blood to all parts of the body from the heart.

1. thinner
2. longer

2. False

Q.

What happens when an artery ruptures?

Q.

Pulmonary vein carries
