The Human Circulatory System is one of the most important and foundational chapters in Biology. It explains how our body transports oxygen, nutrients, hormones, and essential materials — and how waste is removed to keep us alive.
For BPSC TRE 4.0 Bihar Teacher Exam, understanding this chapter is critical because several concept-based, diagram-based, and function-based questions come directly from NCERT.

In today’s special Science Class, Sajid Sir takes you through a complete, structured, easy-to-understand explanation of the entire Circulatory System. The session is designed to build concept clarity, exam accuracy, and deep understanding of how the human body maintains life through an efficient transport system.

🔍 What You Will Learn in This Class (Deep & Detailed Breakdown)
✔️ 1. Introduction to the Circulatory System

A full explanation of what the circulatory system is, why humans need it, and how it acts as the body’s transportation network.

✔️ 2. Structure of the Human Heart

A beautifully simplified yet detailed explanation of:

4 chambers (Right/Left Atria & Ventricles)

Aorta, Pulmonary Artery & Pulmonary Vein

Superior & Inferior Vena Cava

Heart valves and their functions

How blood flows through each chamber

You will learn how the heart pumps nonstop — more than 100,000 times a day — to keep us alive.

✔️ 3. Cardiac Cycle & Heartbeat

Understand how one complete heartbeat occurs, including:
Systole
Diastole
Lub-dub sound
Pacemaker (SA node)
How electrical impulses control heart rhythm

Concepts often asked in TRE exams are explained in the simplest way.

✔️ 4. Types of Blood Vessels (Exam Critical)
Detailed differences with diagrams between:
Arteries (carry blood away from heart)
Veins (carry blood to the heart)
Capillaries (exchange points)

This section includes high-scoring MCQ facts often repeated in previous Bihar Teacher exams.

✔️ 5. Composition of Blood (Most Asked Topic)

Deep explanation of:
Red Blood Cells (RBCs) – Hemoglobin role
White Blood Cells (WBCs) – Immunity types
Platelets – Blood clotting
Plasma – Transportation of materials
Each component is explained with real-life relevance and examples.

✔️ 6. Double Circulation (Important for TRE)

A clear breakdown of:
Pulmonary circulation
Systemic circulation
Why humans need double circulation
How oxygenated and deoxygenated blood move in separate loops
This concept carries direct exam questions.

✔️ 7. Blood Pressure & Pulse Understanding

Know how blood pressure is measured, what systolic and diastolic mean, and how pulse rate changes during physical activity.

✔️ 8. Transportation of Oxygen, CO₂ & Nutrients

A deep explanation of how red blood cells carry oxygen, how carbon dioxide returns to lungs, and how nutrients reach each cell.

✔️ 9. Disorders of the Circulatory System
Basic understanding of:
Heart attack
Hypertension
Low blood pressure

Anemia
Useful for real-life awareness and exam application.

✔️ 10. NCERT + BPSC TRE 4.0 Exam-Focused Questions

The class includes theory + MCQs based on previous years’ TRE, CTET, BTET, and state teaching exams.
