• Actinenchyma — A structural plant parenchymal tissue, characterized by star-shaped cells with large radiating extensions that leave voluminous intercellular air spaces (lacunae) between them. This special type of tissue is specific to aquatic and marsh plants, having the primary physiological role of facilitating gas circulation and ensuring the buoyancy and respiration of submerged organs in oxygen-deficient environments.
• Aerenchyma — A fundamental parenchymal plant tissue structurally characterized by the presence of large intercellular spaces, lacunae, or air-filled channels. It is specific to aquatic (hydrophytic) and marsh plants, playing the vital role of ensuring oxygen and gas circulation to submerged organs and facilitating the buoyancy of aerial parts.
• Aeriferous — Conducting, transporting, containing, or storing air or other gases; it refers specifically to tissues, channels, or vessels of living organisms (especially aquatic plants) structurally adapted for air circulation and storage. In a technical or industrial context, it describes a system of pipes or installations specially designed for conveying pneumatic flows.
• Breathing apparatus — As a noun, it represents a portable technical apparatus or protective device (compressed air tank with a mask) used by firefighters, divers, or miners to breathe in environments with stale air, smoke, or toxic gases. In biology (as an adjective), it describes channels, vessels, or tissues structurally adapted to transport or conduct air within an organism.
