ANATOMY

Detailed explanation-1: -Your lungs are one of the largest organs in your body. The surface area of both lungs is roughly the same size as a tennis court and the total length of the airways running through them is 1, 500 miles.

Detailed explanation-2: -Your trachea is divided into two air passages called bronchial tubes. One bronchial tube leads to your left lung, the other to your right lung.

Detailed explanation-3: -In most people, the trachea is about 4 inches (10 centimeters) long-about the width of your hand. It is about an inch (2.5 centimeters) wide-about as big across as an adult’s finger.

Detailed explanation-4: -Lungs contain approximately 2, 400 kilometres of airways and 300 to 500 million air sacs (alveoli). If stretched out, the total surface area of lungs would be about the same size as half a tennis court.

Detailed explanation-5: -Lung volume increases from about 250 mL at birth to 6000 mL in the adult. The height of a normal adult lung is 27 cm at total lung capacity, but in the range of normal breathing it is approximately 24 cm in height. Externally, the lungs are paired structures that, with the mediastinum, fill the thoracic cavity.
