Model Answer
(i) Vena cava — Transports deoxygenated blood from the body (various organs/tissues) to the right atrium of the heart.
(ii) Pulmonary artery — Transports deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.
Source: Life Processes, Section 5.4.1

Explanation
- The key point examiners look for: both vessels carry deoxygenated blood — a common mistake is assuming arteries always carry oxygenated blood. The pulmonary artery is the exception.
- Always mention source → destination (path) for full marks; naming only the blood type gives half credit.
- "Vena cava is a vein → carries blood to the heart; pulmonary artery carries blood away from the heart to lungs" — this logic confirms direction.
