Gas Exchange Principles in Respiration | Gas diffusion | Respiratory Physiology

✨Understanding Gas exchange between tissues of the body starts with the partial pressures. In this video, i talk about those partial pressures, the different laws guiding gas exchange and how the oxygen and carbon-di-oxide levels change as this exchange happens. I hope it helps!☀️
