Session 1 Overview of membranes and fluid balance

• Passive Facilitated Transport: diffusion of substances through specific membrane proteins.
• Types of primary active transport?

  • P -class- transport H⁺, Na⁺, K⁺, Ca²⁺ ions across cell membranes
  • F -class- transport H⁺ ions across inner mitochondrial membrane
  • V -class- transport H⁺ ions across lysosomal membrane
  • ATP-binding cassette (ABC)-class- transport ions, drugs and xenobiotics across cell membranes
• 5Rs?

  • Resuscitation
  • Routine management
  • Replacement
  • Redistribution
  • Reassessment
