The water level is the same in connected vessels because of the principle of communicating vessels. This principle states that when vessels are connected, the water level will seek to equalize across all connected vessels. This happens because the pressure at the same height in a fluid is the same, so the water will flow between the vessels until the levels are equal. Therefore, even if some vessels have more volume, the water level will still be the same in all connected vessels. **

However, it is important to check the manufacturer's instructions to ensure that the expansion vessel is properly filled and pressurized before installation. **

The vessels are called pulmonary arteries because they carry deoxygenated blood from the heart to the lungs for oxygenation. The term "pulmonary" refers to the lungs, indicating that these arteries are specifically responsible for transporting blood to the lungs. The oxygenation process occurs in the lungs, where carbon dioxide is exchanged for oxygen, and the oxygenated blood is then carried back to the heart through the pulmonary veins. **
