Human Blood Circulatory System Explained | How the Heart and Blood Vessels Work

📝 Video Script (for narration):

🎙️Intro:
Welcome to Mr Science Education!
Today, we’re diving into one of the most fascinating systems in the human body — the blood circulatory system.

🫀 What is Blood Circulation?
Blood circulation is the process that keeps us alive by transporting oxygen, nutrients, and hormones throughout the body — and removing waste products.

🔬 Main Parts of the Circulatory System:

The Heart – The powerful pump with four chambers:

Right Atrium

Right Ventricle

Left Atrium

Left Ventricle

Blood Vessels – The roads that carry blood:

Arteries carry blood away from the heart.

Veins bring blood back to the heart.

Capillaries exchange oxygen and nutrients with body cells.

The Blood – It’s made up of:

Red Blood Cells

White Blood Cells

Platelets

Plasma

🔄 Two Types of Circulation:

Systemic Circulation: Heart → Body → Heart

Pulmonary Circulation: Heart → Lungs → Heart

⚙️ How it Works (in steps):

Deoxygenated blood enters the right atrium.

Moves to the right ventricle.

Pumps to the lungs to get oxygen.

Oxygenated blood returns to the left atrium.

Then flows into the left ventricle.

Finally, it’s pumped out to the whole body!

📌 Why is this important?
Without this system, your body wouldn’t get oxygen or nutrients — and waste couldn’t be removed. It’s your body’s delivery and cleaning system!
