Скачать или смотреть Circulatory System: Heart, Blood Vessels and Blood

This video features an educational song that clearly and engagingly explains the structure and function of the circulatory system, highlighting the roles of the heart, blood vessels, and blood components in sustaining life.

The music illustrates how the heart works as a pump, alternating between systole, which propels blood outward, and diastole, which fills the cardiac chambers. The lyrics describe the movement of blood through the atria and ventricles, emphasizing how coordinated muscle contractions control blood flow.

The song also explores the function of blood vessels, explaining that:
• Arteries transport blood under high pressure;
• Veins contain valves that prevent backflow;
• Capillaries enable gas exchange and delivery of nutrients to tissues.

Additionally, the song explains the components of blood, highlighting plasma as a nutrient transporter, red blood cells as oxygen carriers, white blood cells as defenders of the body, and platelets as key agents in clotting and tissue repair.

With clear explanations and memorable rhythm, the video turns cardiovascular physiology into fun and effective learning, making it ideal for students, educators, and anyone who wants to understand biology in an accessible and enjoyable way.
