Introduction to Cardiovascular System:

Cardiovascular System

Cardiovascular system means the system of heart and blood vessels of human body. The term “cardiovascular” is a combination of two word; “Cardio” and “vascular”. The term “cardio” is derived from “cardiac” meaning Heart and the term “vascular” means blood vessels. So the name itself indicates that cardiovascular systems is the system of heart and blood vessels. Cardiovascular system is also known as “Circulatory System”.
Components Of Cardiovascular System:

Cardiovascular system is made up of three major components; Heart, Blood vessels and blood.
HEART:Heart is a hollow muscular organ made of strong cardiac muscles. Heart can push the blood through the circulatory system with great force. In fact push of the heart is the major force that causes circulation of blood throughout human body. Heart is made up of three layers; Pericardium, Myocardium and Endocardium.

Human Heart

BLOOD VESSELS:Human beings have a closed type of circulatory system (visit my blog post: Difference between open and closed circulatory systems) in which blood does not come in direct contact with body tissues. Instead the blood flows in restricted pathways called blood vessels. Materials are exchanged between blood and body tissues through the walls of blood vessels. Thus blood vessels are pathways of blood flow in human body. There are three main types of blood vessels; Arteries, Capillaries and Veins
BLOOD: Blood is a specialized tissue of body that exists in fluid form. It is one of the five basic types of tissues of human body. (Blog post:Basic tissue types of Human Body). Blood consists of two major portions: Blood cells and Plasma. Plasma is the watery portion of blood that makes it a fluid. 90% of blood plasma is water and remaining 10% are proteins, inclusions and waste products etc. Blood cells are of three main types: Red Blood Cells (RBCs), White Blood Cells (WBCs) and Platelets. :”".
