Lungs
Our 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).
The bronchi are large air passages that branch off from the trachea and direct air into each lung, dividing further into smaller bronchi and bronchioles. They are lined with mucus and cilia to trap and remove dust, pathogens, and other particles from the air we breathe. The bronchi play a crucial role in ensuring that inhaled air reaches the lungs' alveoli, where gas exchange occurs.

The ribs are a set of curved bones that form a protective cage around the lungs and heart, providing structure and safety to these vital organs. They work in coordination with the muscles of the chest to aid in the process of breathing, expanding and contracting as we inhale and exhale. The ribcage is flexible and strong, allowing it to shield the lungs while also accommodating their movement during respiration.
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax) that are essential for breathing and gas exchange. They work by taking in oxygen from the air we inhale and expelling carbon dioxide, a waste product of metabolism, through exhalation. The intricate network of airways and alveoli within the lungs maximizes the surface area for efficient gas exchange, supporting the body's oxygen needs.
