Short Time Reading Aspect Description Atmospheric Pressure (Patm) The pressure exerted by air weight in the atmosphere, typically around 760 mmHg at sea level. It serves as a reference for measuring other pressures in the lungs. Intrapulmonary Pressure (Ppul) Also known as alveolar pressure, it’s the pressure within lung alveoli. This pressure fluctuates above and

Aspect Description Medullary Gradient Definition: The progressive increase in solute concentration from the cortex to the inner medulla of the kidney. Location: From outer cortex down to the inner medulla. Importance: Establishes a concentration gradient critical for water reabsorption and urine concentration, helping the kidney adjust urine concentration according to hydration needs.
