Heart and blood vessel symptoms in states of disease or disorder are widely varied. When the heart or blood vessels become damaged or blocked serious complications can arise.
The heart is essentially a complex muscle and is one of the most critical organs in the body. Together with the lungs, the heart and blood vessels comprise the cardiovascular system.
The heart functions to pump blood to all regions of the body. It has no additional functions. Its four chambers receive or send blood through blood vessels. Two chambers receive blood into the heart and two pump blood out of the heart.
The right side of the heart receives blood returning from the body and pumps it to the lungs. The left side of the heart receives the blood returning from the lungs and pumps it out to the entire body.
While in the lungs the blood pumped by the right side of the heart becomes oxygenated and also clears itself of waste products (including carbon dioxide) built up during its travels through the body.
Oxygenated blood returns to the left side of the heart and is then pumped throughout the body bringing oxygen as well as picking up waste products and gases.
The heart must also oxygenate its own tissues (muscles). It does this through coronary arteries which are its own personal blood supply.
There are many classifications of blood vessels. They differ in size and function. It is when blood vessels become damaged, constricted, or blocked that problems occur. Depending on the location of the blood vessel in the body, different complications may occur.
