The Human Superhighway: How Blood & Circulation Actually Work

our body is a sprawling metropolis of trillions of cells, and without a constant delivery system, everything stops. In this deep dive, we explore the incredible science of Body Fluids and Circulation. From the electrical spark of the heart's pacemaker to the "detour" of the hepatic portal system, learn how your body ensures every cell gets the oxygen it needs while keeping toxins at bay. In this video, you’ll learn: The true role of Blood, Plasma, and Platelets. How the Cardiac Cycle and ECG (P-wave, QRS complex) work in sync. The hidden "drainage" role of the Lymphatic System. What happens when the "highways" get blocked (Hypertension & Atherosclerosis). Timestamps: 0:00 - The Human Body: A Microscopic Metropolis 0:28 - What is Blood?
