Laplace’s law

Laplace’s Law describes the relationship between pressure, surface tension, and radius in curved surfaces like bubbles, blood vessels, or alveoli in the lungs. For a spherical structure For a cylindrical structure P = 2T / r P = pressure inside the sphere (alveoli) T = surface tension r = radius of the sphere P = […]

Oxygen-hemoglobin dissociation curve

  Shift Right Shift Left Shift Affection  for oxygen Decreased affinity Increased affinity Hb-oxygen  binding Oxygen is less tightly bound; more readily released Oxygen is more tightly bound;  less readily released  Causes – Increased CO2 – Decreased CO2   – Increased temperature – Decreased temperature   – Decreased pH (acidosis) – Increased pH (alkalosis)
