Pneumonia is an infection that specifically affects the lungs. It occurs when the air sacs in the lungs become inflamed and filled with fluid or pus, leading to symptoms such as cough, fever, chills, and difficulty breathing. The condition can be caused by various pathogens, including bacteria, viruses, and fungi.

Focusing on the lungs, this vital organ is responsible for gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. When pneumonia strikes, it compromises this function, making it crucial to understand its impact on respiratory health.

The other options refer to different organs; the kidneys are involved in filtering blood and producing urine, the heart pumps blood throughout the body, and the liver plays a critical role in detoxification and metabolism. Thus, pneumonia's specific association with the lungs is what makes it distinct and highlights the need for targeted treatment and management in respiratory care.
