Respiration and Circulation
Description: Oxygen intake, carbon dioxide release, energy production via aerobic or anaerobic respiration.
Description: Oxygen binds hemoglobin, CO₂ dissolves in plasma, exchanged via diffusion in lungs, tissues.
Description: Blood, lymph transport nutrients, gases, wastes; heart pumps, vessels distribute efficiently.
Description: Plasma, RBCs (oxygen transport), WBCs (immunity), platelets (clotting) form blood’s main components.
Description: Platelets activate, fibrin forms mesh, stops bleeding; heart pumps oxygenated blood throughout body.
Description: Heart contracts, relaxes rhythmically; systole, diastole phases ensure continuous blood circulation, maintaining life.
Description: Double circulation ensures separate oxygenated and deoxygenated blood flow, while cardiac regulation controls heart function.
