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.
