It describes external respiration in the lungs, where higher alveolar oxygen diffuses into pulmonary capillaries and higher blood carbon dioxide diffuses into the alveoli, and internal respiration in tissues, where oxygen moves from blood to tissues and carbon dioxide moves from tissues into blood. About 97 to 98 percent of oxygen is transported by hemoglobin, while carbon dioxide is carried as dissolved gas and in forms like carbaminohemoglobin and bicarbonate ions, involving carbonic anhydrase and the chloride shift. The video also covers how changing respiratory rate affects CO2 and pH, including acidosis with low pH from increased CO2 and alkalosis with high pH from decreased CO2."}
