physics of blood

Blood's physics involves fluid dynamics, where blood flows through vessels under pressure created by the heart. Its movement is influenced by factors like viscosity (thickness), vessel diameter, and blood pressure. Blood behaves as a non-Newtonian fluid, meaning its viscosity can change depending on flow conditions, especially when clotting or flowing through narrow capillaries. Red blood cells are suspended in plasma, affecting flow and transport of oxygen. The flow adheres to principles like laminar or turbulent flow, and understanding these helps in diagnosing cardiovascular conditions and designing medical devices.
