The Heart and Circulation of Blood
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 arteries. With the oxygen of the blood having been diffused into tissue cells, the blood that has gone through the digestive tract enters into the hepatic portal system, while blood that has not gone through the digestive tract is transported directly back to the heart. The blood that has done down the digestive tract is brought by the hepatic portal vein to the liver, to be filtered and cleaned before going back to the heart. For the blood to get back to the heart, the liver empties the clean blood into the hepatic vein, leading to the inferior vena cava, which pumps blood into the heart’s right atrium. The cycle then begins again, as the blood in the right atrium makes its way into the pulmonary circuit again. I will talk about these three processes in my paper.
The pulmonary circuit is where the blood becomes revitalized and useful again. Deoxygenated blood, blood whose strength has already been used in the body, travels from the right atrium to the right ventricle through the one-way tricuspid valve. The blood is then pumped into the pulmonary artery. The pulmonary artery is unique, as it is the only artery that carries deoxygenated blood, whereas it would usually be carried by veins. The blood is then taken into the lungs in order
