Class 11 Biology Chapter 11 | Blood Vessels (Arteries, Veins, Capillaries) | New Book 2025

In this Class 11 Biology lecture from the new Punjab Board Biology book 2025, we explore the important topic Blood Vessels including arteries, capillaries, and veins, along with the regulation of blood flow in capillaries. This lesson is specially designed for FSc Part 1 Biology students who want clear concepts, exam preparation, and high scores in board exams. In this video, you will learn the structure and functions of arteries, veins, and capillaries, and understand how each type of blood vessel plays a unique role in the human circulatory system. The lecture explains how arteries carry oxygenated blood away from the heart, how veins return deoxygenated blood to the heart, and how capillaries allow the exchange of gases, nutrients, and wastes between the blood and body tissues. You will also study the regulation of blood flow in capillaries, including the role of vasoconstriction, vasodilation, nervous control, and chemical control of capillaries. This concept is very important for Class 11 Biology exams, FSc Part 1 board preparation, and medical entry test preparation. This lecture is ideal for students searching for Class 11 Biology Chapter 11, blood vessels lecture, arteries veins capillaries notes, human circulatory system class 11, FSc Biology Chapter 11 explanation, and Punjab Board Biology 2025 lectures.
