An air cell is a small, air-filled space found in various organisms and structures. In bird lungs, air cells are connected to air capillaries and enhance gas exchange. In plants, they can provide buoyancy or insulation. In foams and certain foods, air cells contribute to texture and structure. Think of them as tiny pockets of air that serve different purposes. They can act like miniature balloons. 🎈 They are essential for diverse biological functions. Each functions like a mini-lung. 🫁
