The cardiovascular system is a vital part of our body and it is crucial for us to lead a healthy lifestyle to maintain the structures of our body. Structures of the cardiovascular system include the heart, blood vessels and blood.

Structures of the Cardiovascular System


The heart is the most important organ in our body as it provides every part with blood. The heart pumps blood by producing electrical impulses which cause the ventricles to contract and relax and pump blood to the arteries, and this process is called a cardiac conduction. It is the only organ that works without rest. Without the heart, the human body will simply perish so it is necessary for us to lead a healthy lifestyle to keep our organs healthy and functioning.


Blood is made up of a protein called hemoglobin, which gives it a deep red colour. The main components of the blood are red blood cells, white blood cells and plasma.

Blood Vessels

The transportation used to send blood back and forth throughout the body from the heart to various organs is through blood vessels. There are billions of blood vessels that are tangled with each other in an endless network. Blood vessels carry the de-oxygenated blood from the heart to the lungs and the purified blood back to the heart to be transported to various organs of the body. Though blood vessels are not exactly organs, they play a vital role in the healthy functioning of the body.

Diseases that relate to the Cardiovascular System

The Cardiovascular System has the responsibility of providing blood to all parts of the body, using the main organ, the heart. The heart has a very vital role of keeping the body filled with blood with the help of the billion intertwined blood vessels. This shows that if there are problems with the heart, than there are many consequences to bear. Although, many people in this world have heart related problems and diseases and I will explain how some are caused and what effect they can have on us.

One is the Coronary Heart Disease. This disease is formed by many fatty deposits of food every day that accumulate on the inner wall of the blood vessels that supply the heart muscle with blood. These fatty deposits clog the arteries and reduce the flow of blood to the heart. This process is called atherosclerosis and begins when people are young and can be well advanced when in middle age. That is the main reason for cardiac arrests and other sudden heart failures. By having a healthy diet, which includes having less oily food and fat, is a good way you can prevent atherosclerosis. Hypertension is another big problem that is the cause of heart attacks and is caused by mental disturbance or pressure caused by depression or stress. It causes high blood pressure, and is sometimes a fatal situation. Meditating is a good way of having a peaceful mind. Doctors and many associations have proved that meditating reduces activation of the nervous system which widens the blood vessels which helps the heart and other organs because there is an increased flow of the blood. It also reduces stress of hormones, such as adrenaline, noradrenaline, and cortisol. This leads a peaceful life and on the other hand helps your heart and prevents consequences like high blood pressure and cardiac arrest.

Diabetes is another major disease and is the cause to many deaths around the world. More deaths have been caused by diabetes than deaths of breast cancer and aids combined! There are many causes of diabetes. There are types of diabetes. type 1 is normally caused through genetics and type 2 is through genetics but also through lifetime factors. Being overweight increases your risk for developing type 2 diabetes, and a diet high in calories from any source contributes to weight gain. Research has shown that drinking sugary drinks is linked to type 2 diabetes. The American Diabetes Association recommends that people should limit their intake of sugar-sweetened beverages to...
