Human Anatomy and Physiology

Like Duolingo, but for Human Anatomy and Physiology. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

What you'll learn

Key ideas in Human Anatomy and Physiology

  • Osteoclasts break down bone matrix through resorption
  • Mechanical stress triggers osteoblast activity in high-load areas
  • Osteoblasts deposit new hydroxyapatite to build bone
  • Trabeculae align along lines of physical stress to maximize strength
  • Density increases when bone formation exceeds resorption
  • Bone tissue is resorbed in areas where mechanical loading is absent
  • The balance between osteoblast and osteoclast activity in bone density
  • Application of Wolff’s Law to physical activity and bone structure
  • PTH is released when blood calcium levels drop too low
  • Blood vessels rupture to form a clot at the break site
  • Calcitonin is secreted by the thyroid to prevent hypercalcemia
  • Chondrocytes create a soft bridge before ossification occurs
  • The skeletal system acts as the primary buffer for blood calcium
  • Spongy bone is eventually replaced by organized compact bone
  • The hormonal regulation of blood calcium levels
  • The biological sequence of fracture repair
