📖 1. Cardiovascular System

🔑 Key Concepts & Definitions

• Cardiovascular System: The body system composed of the heart, blood vessels, and blood, responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body.

• Heart: A muscular organ that functions as a pump, creating the pressure needed to circulate blood through the body via its four chambers—right atrium, right ventricle, left atrium, and left ventricle.

• Blood Vessels: A network of arteries, veins, and capillaries that carry blood. Arteries transport oxygen-rich blood away from the heart, while veins return oxygen-poor blood back to the heart.

• Pulmonary Circulation: The pathway where the right side of the heart pumps oxygen-poor blood to the lungs for oxygenation and removal of carbon dioxide.

• Systemic Circulation: The pathway where the left side of the heart pumps oxygenated blood to body tissues and returns deoxygenated blood to the heart.

📝 Essential Points

• The heart has four chambers: right atrium, right ventricle, left atrium, and left ventricle, functioning as two pumps for pulmonary and systemic circulation.
