capillaries of small intestine; superior mesenteric vein; hepatic portal vein; liver sinusoids; hepatic vein; inferior vena cava
trace the flow of a drop of blood from the small intestine to the right atrium of the heart
Small veins that surround the intestine to the port vein which leads into the liver, then inferior cava vein, right atrium of the heart
Portal vein, liver, hepatic vein, inferior vena cava.
the blood through superior and inferior mesenteric veins first flows through the portal circulation to liver then via hepatic veins it enters inferior vena cava and then to riht atrium
for blood to reach the right atrium from the small intestines it follows this path: Small veins - portal vein- liver- inferior caval vein - right atrium The blood flows mostly northwards
It separates the left atrium and left ventricle. Oxygenated blood is pumped into the left atrium after having visited the lungs through the pulmonary veins. Then the atrium contracts and moves blood through the bicuspid valve and into the left ventricle. The bicuspid valve is important because it allows the blood to only flow into the ventricle and not return back to the atrium. Another name for it is the mitral valve.
the pulmonary veins, the only veins to carry oxygenated blood empty into the left atrium.
Oxygen-poor blood enters the heart through the right atrium
Oxygenated blood leaves the lungs through the pulmonary veins and then into the left atrium.
the pulmonary artery
the mitral and tricuspid valves
Right atrium is where the blood enters through superior or inferior vena cava.
Blood flows from the right atrium through the tricuspid valve to the right ventricle.
From vena cava to Right atrium to right ventricle through pulmonary arteries (deoxygenated blood) to lungs back through pulmonary veins (oxygenated blood) to left atrium to left ventricle to aorta (the body)
The left atrium of the heart receives oxygented blood from the pulmonary veins returning oxygenated blood to the heart.
The right atrium receives "de-oxygenated" blood (blood from the body containing less oxygen and more carbon dioxide) and the right ventricle sends this blood toward the lungs.
