GENERAL HISTOLOGY

Detailed explanation-1: -The lungs are soft and spongy because they are mostly air spaces surrounded by the alveolar cells and elastic connective tissue.

Detailed explanation-2: -The alveoli are responsible for the spongy nature of the lung. These alveoli are lined by flattened epithelial cells called pneumocytes with a single opening. The alveolar wall or septum is made up of three tissue components: surface epithelium, supporting tissue, and an extensive network of continuous capillaries.

Detailed explanation-3: -Lungs have a spongy texture and have a pinkish-gray hue. Also, they are anatomically described as having an apex, three borders, and three surfaces.

Detailed explanation-4: -Language switcher. Your lungs are the pair of spongy, pinkish-gray organs in your chest. When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out).

Detailed explanation-5: -The lungs are soft, light, spongy, elastic organs that normally, after birth, always contain some air.
