Study Notes
Cardiovascular System Overview
- The cardiovascular system is also known as the blood-vascular system.
- It circulates blood through arteries, veins, and capillaries, not just arteries.
- The heart is surrounded by a protective membrane called the pericardium.
Blood Composition and Function
- Blood carries toxins and waste to the liver and kidneys for elimination.
- White blood cells, also known as leukocytes or white corpuscles, play a crucial role in immunity.
- Plasma is the fluid component of blood that transports nutrients and waste.
Types of Blood Vessels
- Arteries are thick-walled, elastic vessels that carry oxygenated (pure) blood away from the heart.
- Veins are thin-walled vessels that return deoxygenated (impure) blood to the heart.
- Capillaries are small vessels that facilitate the exchange of nutrients and waste between blood and cells.
Circulatory Processes
- Systematic or general circulation refers to blood traveling from the heart to body tissues and back.
- All blood from the head, face, and neck returns via the internal and external jugular veins.
Key Arteries and Their Functions
- The common carotid artery supplies blood to the face, head, and neck.
- The internal carotid artery supplies blood to the brain, eyes, and forehead.
- The external carotid artery supplies blood to the skin and muscles of the head.
- The ulnar artery supplies blood to the little finger side of the arm and hand, while the radial artery supplies the thumb side.
- The popliteal artery supplies blood to the knee joint and muscles in the thigh and calf.
- Anterior tibial artery supplies blood to below the knee and branches into smaller arteries.
Key Veins and Their Functions
- The saphenous vein transports blood from the foot to the femoral artery.
- The femoral vein carries blood to the heart and lungs for oxygenation.
Lymphatic System
- Lymph nodes filter foreign particles from lymph vessels.
- Lymph distributes white blood cells essential for the development of immunity.
Cardiovascular System Components
- The four main components of the cardiovascular system are the heart, arteries, veins, and capillaries.
