@launchpad.learning: The Heart and Blood Vessels in 60 Seconds! ⏱️ Everything you need to crush this topic for your GCSE Biology exam! 🫀✨ ❤️ The heart pumps blood around the body through blood vessels. 🩸 Arteries have thick walls to carry blood at high pressure, while veins have thin walls to return blood at low pressure. 🌬️ Capillaries are one cell thick for gas exchange. 💡 The heart has four chambers connected to four blood vessels and valves to prevent backflow. 🔄 Blood flows through the heart twice: deoxygenated blood goes to the lungs, oxygenated blood returns to the body.
