The pulmonary artery is the blood vessel that carries deoxygenated blood away from the heart. It is the only artery in the body that carries deoxygenated blood. The pulmonary artery originates from the right ventricle of the heart and divides into two branches, which lead to the left and right lungs.
The deoxygenated blood is pumped from the right ventricle into the pulmonary artery and is then transported to the lungs. In the lungs, the blood undergoes oxygenation through the process of gas exchange, where carbon dioxide is released, and oxygen is taken up by the red blood cells. After oxygenation, the blood returns to the heart through the pulmonary veins as oxygenated blood.
Coronary arteries, on the other hand, are responsible for supplying oxygenated blood to the heart muscle itself. They originate from the aorta, the main artery leaving the heart, and supply the heart with oxygen and nutrients.

Answer:
The correct answer is option 'A': Pulmonary artery only.
The pulmonary artery is the only vessel in the body that carries deoxygenated blood away from the heart. It is responsible for transporting blood from the heart to the lungs, where oxygen is added and carbon dioxide is removed through the process of respiration.
Explanation:
The cardiovascular system consists of the heart, blood vessels, and blood. Its main function is to transport oxygen, nutrients, hormones, and waste products throughout the body.
The Heart and Blood Flow:
- The heart is a muscular organ located in the chest cavity. It consists of four chambers: two atria and two ventricles.
- The right atrium receives deoxygenated blood from the body through the superior and inferior vena cava.
- The right atrium contracts, pushing the blood into the right ventricle.
- The right ventricle then pumps the deoxygenated blood into the pulmonary artery.
The Pulmonary Artery:
- The pulmonary artery is the only artery in the body that carries deoxygenated blood. It is connected to the right ventricle of the heart.
- The pulmonary artery splits into two branches, one for each lung. These branches further divide into smaller arteries and eventually into capillaries.
- In the capillaries of the lungs, gas exchange occurs. Oxygen from inhaled air diffuses across the thin walls of the capillaries into the blood, while carbon dioxide, a waste product, diffuses out of the blood into the lungs.
- The oxygen-rich blood then returns to the heart through the pulmonary veins.
Other Vessels:
- The coronary arteries are responsible for supplying oxygenated blood to the heart muscle itself. They branch off from the aorta, which is the main artery that carries oxygenated blood to the rest of the body.
- The coronary arteries do not carry deoxygenated blood away from the heart; instead, they supply oxygenated blood to the heart muscle, ensuring its proper function.
In summary, the pulmonary artery is the vessel that carries deoxygenated blood away from the heart. The coronary arteries, on the other hand, supply oxygenated blood to the heart muscle.
