The Heart and Circulation of Blood

In this research paper, I will be analyzing the process of blood circulation within the human body. I will be focusing on the pulmonary circuit and the systemic circuit, as well as the relationship with the hepatic portal system. The combination of these systems allows the body to function properly and maintain unconscious homeostasis. I will also be talking about the effects that fitness and diet have on these processes.
The pulmonary circuit passes already-used, deoxygenated and carbon dioxide-rich blood from the heart to the lungs in order for that the blood to become oxygenized. Once oxygenized, the blood is distributed throughout the body via the systemic circuit, being transported in …show more content…

In addition to the systemic circuit, there is a path that the blood can take through the mesenteric artery that allows it to pass through the hepatic portal system. The mesenteric artery runs the blood to the gastrointestinal tract and spleen and then to the liver. The blood’s oxygen is exchanged with carbon dioxide in the capillaries of the gastrointestinal tract, but some of the blood does not take part in this exchange, and instead travels through the hepatic portal vein to the liver. The liver is particularly special, as it receives both oxygenated and deoxygenated blood. The liver then cleanses the blood of bacteria and any other harmful substance that may be in it (King, 2010). From here, the blood flows to the hepatic vein, which is then joined into the inferior vena cava, and ultimately back to the heart.
It is vital that these processes are carried out without fault. They are all important to maintaining homeostasis, and one of the ways to keep the blood flowing healthily is with exercise and a balanced diet. Proper eating and exercise are important for allowing our bodies to fight problems such as pulmonary hypertension, which an individual can get due to high blood pressure, and causes the victim to have a shortness of breath (Fagard, 1999). In addition, studies have shown that exercise
