Explore Our Interactive Circulatory System Slides
Have you ever wondered how blood travels around your body and delivers oxygen to every cell? In this lesson, we dive into the fascinating journey of blood through the heart, lungs, and the rest of your body. Get ready to learn about:

The Heart: Four chambers that pump blood in and out.

Major Blood Vessels: Arteries, veins, and capillaries, as well as how they each play a unique role.

Pulmonary vs. Systemic Circulation: Two loops that make sure your cells stay supplied with oxygen.

Watch: “The Heart and Circulatory System – How They Work”

What Is It About?
This short video shows how your heart functions as a powerful pump, moving blood throughout the body. It explains:

• Heart Structure: The heart’s four chambers, how the right and left sides keep oxygen-poor and oxygen-rich blood separate, and why that matters.
• Valves & Flow: The role of valves in preventing backward flow, plus how the heart muscles contract and relax (systole and diastole).
• Oxygen Exchange: How oxygen-poor blood heads to the lungs and returns to the heart, rich in oxygen, ready to travel to the rest of the body.
• Electrical Conduction: The “wiring” that keeps your heart beating in a regular rhythm.
• Coronary Arteries: The blood vessels that nourish the heart itself.

Instructions
Watch the entire video carefully.

Take brief notes on any facts that stand out to you (e.g., how many times the heart beats in a day or what “systole” and “diastole” mean).
