The heart is made up of four chambers‚ the left and right atria‚ and the left and right ventricles. “The left and right sides of the heart do not communicate with one another after birth and are separated by a thick interventrical or interatrial septum” (Prater‚ 2008). The top (atrium) and bottom (ventricle) parts of the heart are separated by a valve‚ which prevents the backflow of blood. Blood enters the heart through the inferior and superior vena cava carrying deoxygenated blood. The vena cava

ending at the heart‚ describe blood flow through the portal system (naming major vessels and structures you pass along the way) AND WHY BLOOD FLOWS THROUGH THE LIVER (detail the function of the liver). Include the names of vessels as you travel through them in the proper order. After‚ describe What produces bile (which cells)‚ the pathway it takes back to the GI tract‚ and its function (should include an enzyme). 3 main veins come together to form the hepatic portal vein and bring blood to the liver:

When a baby is developing maternal blood supplies the oxygen‚ blood‚ and nutrients to the fetus and takes away the waste. The exchange of maternal blood and fetal blood to the fetus happens through the placental membrane and the umbilical cord vessels. The umbilical vein goes into the body through the umbilical ring‚ and half of the blood running though it goes to the liver and the rest goes to the ductus venous. It joins with the inferior vena cava. Blood goes to the fetal right atrium from the

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

The heart is an organ that acts as a ‘’pump’’ because it pumps blood continuously that is rich in a high concentration of oxygen throughout the organs of the human body such as the brain. Blood is carried through tube like structures called blood vessels such as the artery and the vein. The arteries carry blood from the heart at high pressure which contains a high concentration of oxygen and nutrients to supply the organs. Veins carry blood at low pressure to the heart which contains a high concentration

Mechanisms of Blood Flow in the Human Forearm during Mental Stress‚ Following Isometric Exercise and after Occlusion ------------------------------------------------- 1. Introduction A common technique in measuring blood flow in the human forearm is by venous occlusion plethysmography. The fundamental principle is that if the venous return from the arm is blocked‚ the forearm will swell at a rate relative to the rate of the arterial inflow (Whitney‚ 1953). However‚ the rate of increase in volume

Blood Flow The Path blood takes through the body is a very interested one. In this essay you will heard about the path blood takes from the right femoral vein to lower lobe of the right lung via the pulmonary artery. If blood did not flow through the body we as humans could not function the way we currently do. Oxygenated blood is carried through the body by veins and arteries and this is what feeds the body so it can function (Thibodeau‚ Patton‚ 2008.). Oxygenated blood is carried through the

system is composed of blood vessels‚ blood‚ and the heart. This allows the system to play an important role in the moving of both nutrients and wastes in and out of the blood to maintain an overall homeostasis within the body. The previously completed experiments each had the objective of understanding how various factors may have an influence on blood flow rate. These factors include the effect of blood vessel radius‚ the effect of blood viscosity‚ as well as the effect of blood vessel length‚ and
