SCD also known as sickle cell disease affects the blood and cardiovascular system. There are six different types of SCD. The following discussion will include cause, symptoms, diagnosis, treatment and prevention. The proper education on this disease will give patients and the public a better knowledge of the common unfamiliarity with SCD.

The cardiovascular system consists of the heart, arteries, capillaries, veins, and blood. The organs in the cardiovascular system are a vital part of the human body that helps maintain homeostasis. The function of the cardiovascular system is to supply the body with O2, nutrients to the tissues of the body and the removal of waste (Shier, Butler, & Lewis, 2012, p.341, 342). The blood is a system that is incorporated in the cardiovascular system. Blood is a vital part of the cardiovascular system. The blood consists of RBCs, WBCs, plasma, and platelets. The blood contributes to every organ throughout the human body. The function of the blood is to transport O2, CO2, wastes, nutrients, hormones, lipids, and vitamins. The blood is also responsible for the protection of the body when there are invaders, or any kind of blood loss. Another function of the blood is to regulate the bodies’ temperature, fluid and pH balance (Shier, et al., 2012, p.319).

The cardiovascular system has a main component to make the system work. The heart is essential for the functioning of the cardiovascular system. The basic function of the heart is to pump the blood throughout the body. There are two different circuits of blood flow, the pulmonary circuit and the systemic circuit. The pulmonary circuit within the heart pumps the deoxygenated blood from the right side of the heart to the lungs. In the lungs, the deoxygenated blood is enriched with O2, releases out the waste CO2 and returns to the left side of the heart. In systemic circuit, the heart pumps the O2 rich blood with the nutrients from the left side of the heart to the tissues of the body with the exception the heart and lungs. As the O2 rich blood is being disturbed to the body by blood vessels, it is dropping the O2 to the tissues of the body, picking up the CO2 and wastes and bringing the now deoxygenated blood back up the right side of the heart to be enriched with O2 again by the lungs (Shier, et al., 2012, p.341).

The cardiovascular organs work together like a well oiled machine. The heart, blood vessels, arteries, arterioles, capillaries, veins, and blood must work together to maintain the homeostasis of the body. Along with these organs, they have to be able to work with other organs that are not a part of their system, but are essential to the homeostasis of the body. The lungs are important to the cardiovascular system. The lungs work with the heart allowing with the blood to be brought through the lungs, allowing CO2 to be released and O2 to be replaced back into the blood (Shier, et al., 2012, p.341). The blood vessels, arterioles, capillaries and veins act as a highway for the body. This is where the blood can be transported through the body and replenishes the body with O2. Then it is taken back to the heart, to the lungs to release the CO2 and regain the O2, back to the heart, and then taken away from the heart to replenish the body (“Cardiovascular System,” n.d. para.5). It is important that the systems work together to maintain the balance of the body. If one system does not function the right way, it will then affect the other systems. An example would be if the heart was not pumping the blood throughout the body. The body will not receive enough O2 and will cause the lungs to speed up and produce rapid breathing (Shier, et al., 2012).

When diseases are introduced into the body such as SCD, it can affect the cardiovascular system and the respiratory system. This disease can also affect other vital organs. SCD can throw off the body’s homeostasis and this can result in destruction of the body.

SCD is caused by an abnormal type...
