Study Notes
Cardiovascular System: Transport and Circulation
- The cardiovascular system is responsible for transporting oxygen-rich blood and nutrients throughout the human body.
- It also removes waste products from the body's organs.
- It consists of three main types of blood vessels: arteries, veins, and capillaries.
- The system is a closed system, meaning blood flows continuously in a circuit.
Blood Vessel Types
- Arteries: Transport blood from the heart to the organs.
- Veins: Transport blood from the organs to the heart.
- Capillaries: Tiny blood vessels responsible for exchanging oxygen, nutrients, and waste products between the blood and the surrounding tissues.
The Heart: The Engine of Circulation
- The heart is a hollow, muscular organ divided into four chambers: two atria (upper chambers) and two ventricles (lower chambers).
- Right Side: Receives deoxygenated blood from the body and pumps it to the lungs.
- Left Side: Receives oxygenated blood from the lungs and pumps it to the body.
- Each heartbeat involves a coordinated contraction of the heart chambers.
Blood Flow Through the Heart
- Deoxygenated Blood: Enters the right atrium from the body via the vena cava.
- To the Lungs: The right atrium pumps blood into the right ventricle, which then pumps it to the lungs through the pulmonary artery.
- Oxygenation: In the lungs, blood exchanges carbon dioxide for oxygen in the capillaries of the alveoli (tiny air sacs).
- Oxygenated Blood: Returns to the left atrium via the pulmonary veins.
- To the Body: The left atrium pumps oxygenated blood into the left ventricle, which then pumps it to the body through the aorta.
- This cycle continues throughout life, ensuring the body's oxygen supply and waste removal.
