Question

All arteries carry oxygenated blood except
A. Systematic
B. Haptic
C. Pulmonary
D. Cardiac

Answer 1

Hint:-The artery is a part of the circulatory system, it is credible for the delivery of oxygen and nutrients to the cells, also for the removal of carbon dioxide and waste commodities. The artery is a type of blood vessel that mainly carries the oxygenated blood from the heart to other parts of the body, where it gets deoxygenated.

Complete Answer:-The diameter of the artery is small. Hence they have narrow lumen which is responsible for the high pressure. The wall of the artery divides into 3 layers: Tunica media (middle layer and composed of smooth muscle cells), Tunica intima (innermost layer) and Tunica externa (outermost layer, made up of collagen fibres). The systemic artery is the arteries of the systemic circulation. This artery transmits oxygenated blood from the heart to the arterioles, and then to the capillaries where the exchange of nutrients and gases occurs and blood becomes deoxygenated, which returns to the heart. A short blood vessel that supplies oxygenated blood to the liver, duodenum portion of small intestine, pancreas, and gallbladder. Such a blood vessel is known as Hepatic artery. Arteries generally carry oxygenated blood. But pulmonary artery is the artery that transmits deoxygenated blood away from the heart to the organs (like lungs and placenta, respectively) where it gets oxygenated.

So, the right option is C i.e. Pulmonary.

Note:- Pulmonary vein works similar to the arteries. Because veins mainly carry deoxygenated blood to the heart but the pulmonary vein carries oxygenated blood as well. Also, the umbilical artery works similarly as a pulmonary artery. Because this artery transmits deoxygenated blood from a foetus to the mother.
