Functions And Complex Anatomy Of The Cardiovascular System

According to the Discovery Channel, the Cardiovascular System is the generator that drives the bodily machine of humans (Discovery Channel, â€Å"Your Cardiovascular System,† 2016). Its multiple functions and complex anatomy helps humans get through vital tasks (National Geographic, â€Å"Heart,† 1996). Such as, breathing, blood circulation, and food intake. In other words, the cardiovascular system delivers and transports oxygen and carbon dioxide throughout the body, transports and circulates blood throughout the body, distributes nutrients and food within the body and transports waste products out of it (National Geographic, â€Å"Heart,† 1996). It also takes part in the circulation of hormones (National Geographic, â€Å"Heart,† 1996).

Anothe r part of the cardiovascular system is blood. Blood is a bodily fluid that runs through the veins, arteries and capillaries to help the cardiovascular system perform its job (National Geographic, â€Å"Heart,† 1996). On average, adults have about 5 litres of blood. Blood is the stream in the human body that takes part in the transportation of oxygen and nutrients, and filtering out waste products (The American Society of Hematology, â€Å"Blood Basics,† 2016). Other functions of blood are protection of the human body by forming blood clots to avoid blood loss, fighting of infection through cells and antibodies, and the regulation of body temperature (The American Society of Hematology, â€Å"Blood Basics,† 2016). The blood is also composed of certain materials. The blood is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (The American Society of Hematology, â€Å"Blood Basics,† 2016). The last main part of the cardiovascular system is blood vessels. Blood vessels are tubes in the system that carries the blood (BBC, â€Å"The Circulatory System,† 2014). The three types of blood vessels are arteries, veins and capillaries (BBC, â€Å"The Circulatory System,† 2014). Arteries transport blood away from the heart (BBC, â€Å"The Circulatory System,† 2014).
