What Is Arterial Blood?

The oxygen rich blood returns from the lungs and it goes through the pulmonary vein to the left atrium.

The blood is pumped by the heart through the afferent bronchial arteries to capillaries in the gills, where the blood is oxygenated). The blood

The hearts function as a double pump that serves two circulations. The pulmonary pump in the right side of heart is provided for the gas exchange in the body, and the systemic circulation in the left side provides the functional blood supply to all body tissues. The functional blood to the heart is provided by the coronary arteries. Right coronary artery supplies the heart through the posterior interventricular and marginal artery branches; and the left coronary artery supplies the heart via anterior interventricular artery and the circumflex artery. The myocardium is drained by great, small, and middle cardiac veins which

Blood comes from the Superior and Inferior vena cava, into the right atrium. As the right atrium fills with blood, it contracts and the tricuspid valve opens and the blood pumps into the valve. When the right ventricle is full the tricuspid valve close to ensure blood moves in the right direction. The blood then moves to the right ventricle and into another valve called the Pulmonary valve. Then moves to the pulmonary artery and into the lungs. The blood moves into the lungs and picks up fresh oxygen. Then it returns to the left heart through the pulmonary veins to the left atrium. It passes through the mitral valve and enters the left ventricle. Oxygenated blood moves into the aortic valve and into the Aorta to reach all parts of the body ( heart.org).

It pumps into the right ventricle, which in turn pumps the blood via the pulmonary artery (the only artery without O2) to the lungs to get deoxygenated.

The circulation of blood allows for the transport of nutrients, gases, blood cells and hormones for immunological defense, nutrition, as well as temperature, pH and homeostatic maintenance. The heart muscle circulates blood, a fluid containing erythrocytes, leukocytes platelets and plasma. Since humans have a closed cardiovascular system, gases and nutrients diffuse across blood vessels into interstitial fluid, which then carry these essential components to various cells, while moving cellular waste products away. The arteries transport oxygenated blood from the left ventricle through the aortic semilunar valve. Circulation begins in the aorta, a large, arched, thickset artery that branches into major arteries of the trunk as well as arteries of the lower extremities below the diaphragm. Capillaries are a system of small blood vessels that transport blood to the venous system after distributing

Meanwhile, the left receives the now oxygen rich blood that comes from the lungs and is then pumped through the arteries. However, this time the left ventricle receives the

Blood flows from the tissues → superior and inferior vena cava → right atrium → tricuspid valve → right ventricle → pulmonary semilunar valve → pulmonary artery → lungs → pulmonary veins → left atrium → bicuspid (mitral) valve → left ventricle → aortic semilunar valve → aorta →body tissue.

Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work

in the lower half of the heart. The ventricles pump blood to the lungs and the rest of the body.

Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns

The left side of the heart, has the left atrium and ventricle that takes in oxygenated blood from the lungs and pumps it out of the aorta.

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

The heart pumps blood vigorously through the vessels to all parts of the body, nourishing the organs

A healthy heart pumps blood continuously through the circlutory system. It’s normal size is a little larger than a fist. The heart has four chambers, two on the right and two on the left. The two upper chambers are called the atria and the lower two are known as the ventricles. The right atrium takes in deoxygenated blood from the rest of body and sends it back out to the lungs through the right ventricle where the blood becomes oxygenated. Oxygenated blood travels from the lungs to the left atrium, then onto the left ventricle, which pumps it to the rest of the body.
