Lungs

• The trachea, or windpipe, connects the lungs to the throat and allows air to pass in and out.
• Bronchial tubes branch off from the trachea and lead to smaller tubes called bronchioles.
• Damage to the bronchioles can lead to obstruction of airflow in the lungs.
• The trachea is a tube that connects the larynx to the bronchi, carrying air into and out of the lungs.
• The bronchioles distribute oxygen-rich air and remove carbon dioxide from the lungs.
• The bronchioles are small branches of the bronchial tubes that penetrate into the lung tissue.
• The lungs are the organs responsible for gas exchange.
• Bronchi are large tubes that branch off from the trachea and lead into smaller bronchioles within the lung tissue.
• The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.
• The trachea has rings of cartilage to keep it open during breathing.
• Alveoli are tiny sacs where gas exchange occurs between the bloodstream and the atmosphere.
• Alveoli are tiny sacs at the end of the bronchioles where gas exchange occurs between the bloodstream and the atmosphere.
• Carbon dioxide diffuses from the capillaries into the alveoli due to its higher concentration gradient.
• Lung tissue is composed of alveolar walls made up of epithelial cells with thin membranes, allowing for efficient diffusion of oxygen and carbon dioxide.
