Explore the crucial mechanisms of carbon dioxide transport in the blood, essential for removing this metabolic waste product from tissues and delivering it to the lungs for exhalation. This article details the three primary methods: transport in red blood cells, as bicarbonate ions in plasma, and dissolved directly in plasma.

Discover the vital process of internal respiration, where oxygen is delivered from the bloodstream to body cells, and carbon dioxide, a metabolic waste product, is collected for transport back to the lungs. This article elucidates the crucial diffusion across tissue capillaries and the roles of plasma and red blood cells in sustaining cellular life.

Explore the intricate process of external respiration, where oxygen enters the bloodstream and carbon dioxide is released in the lungs. This article details the diffusion across the respiratory membrane and the critical roles of hemoglobin and carbonic anhydrase in facilitating vital gas exchange.
