Respiratory Organ 100%

: A dense network of capillaries surrounds the respiratory surface to transport absorbed oxygen throughout the body immediately. Diversity of Respiratory Systems

: Millions of tiny structures (like alveoli in humans or filaments in fish) maximize the area available for gas to cross into the blood. respiratory organ

To function efficiently, all specialized respiratory organs across species share several key physical characteristics: : A dense network of capillaries surrounds the

: Gases must dissolve in liquid before they can diffuse across a membrane, meaning respiratory organs must remain moist to function. respiratory organ
