The Human Circulatory System
The Human circulatory system, (HCS) consists of the body’s blood and lymphatic vessels, which provides the body with its needed essentials, such as oxygen and nutrients. The HCS consists of lungs, the heart, veins, as well as, blood vessels. On an average there are at least five liters of blood in the human body. This blood circulates continuously from the heart to other organs of the body,and vice versa, hence the name Human Circulatory system. The HCS also provides a route for the absorption of waste through the circulation of lymph and blood. Some waste becomes excreted during the breathing process.
Human Circulatory System Diseases
The human circulatory system may be prone to a variety of diseases, especially when the immune system is unable to fight attacking bacteria. There are a wide range of human circulatory system diseases, which are usually vascular or lymphatic in nature.
The most common human circulatory disease is the disease of the heart. Disease of the heart has been reported to be the number one cause of death in the US; it is also very instrumental in the cause of physical disabilities. A heart disease may develop into various forms, but the most popular type is the infection of a coronary artery. A coronary heart disease is caused by impedance in the coronary artery that is responsible for feeding the heart. Another popular heart condition is the failure of the heart; this is due to the dysfunction of the heart, resulting from damage to the heart’s valve.
Vascular diseases are found in the arteries and capillaries that provide tissues, and organs of the body with nutrients, and oxygen. A common vascular disease is hypertension. The cause of this disease is not traceable in most cases; this is because it can be caused by many factors, even by the use of medications.
Atherosclerosis is another vascular disease; this takes place when plaques develop on the walls of the arteries, and in cases where plaque has developed on a coronary artery it is considered dangerous. Another dangerous disease due to development of plaque is Carotid heart disease, plaques causes impedance in the supply of blood to the brain.
Lymphatic diseases are found in the nodes, and vessels of the lymphatic system. These vessels, and nodes support the transmission of lymph, and the immune system’s white blood cells throughout the body, which are also used to fight bacteria when the body becomes infected. The circulation of additional body liquid also takes place in the lymphatic system. This is to ensure that body does not store more liquid than needed. Lymphatic diseases include obstruction, and infection of lymphatic vessels, as well as cancer, specifically lymphoma, and lymphoproliferative syndrome.
How to prevent Human Circulatory System Diseases
- Control your cholesterol intake. Too much cholesterol can build up, and form plaque in the arteries.
- Exercise often, obesity and inactivity can strain the heart, which may lead to the development of various types of human circulatory system diseases.
- Minimize the consumption of alcohol.
- Do not smoke.
