What Is Arterial 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

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 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

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.

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.

Blood then travels out toward the lungs for oxygenation via the pulmonary artery and returns to the heart through the pulmonary veins entering the left atrium. It is pumped through the mitral valve into the left ventricle to exit the aortic valve to the circulation via the aorta. The questions asked in the lab packet directly related to the anatomy and physiology of the heart which allowed to understand how the heart works as a

Which blood vessel shown in the figure carries oxygenated blood to the lower thoracic cavity and the abdominal cavity of the body?

Arteries: carry blood away from heart; oxygenated except for pulmonary circulation and umbilical vessels of fetus

Apical impulse (pulse): the pulse measured with stethoscope at 5th intercostal space mid line with the clavicle

Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues. Blood is pumped from the ventricles into large elastic arteries that branch repeatedly into smaller and smaller arteries until the branching results in microscopic arteries called arterioles. The arterioles play a key role in regulating blood flow into the tissue capillaries. About 10 percent of the total blood volume is in the systemic arterial system at any given time.

It is the only artery that carries oxygenated blood. The artery forces blood to the lungs for gaseous exchange to take place this is because the blood from the superior and inferior vena cava that goes into the right atria and to the right ventricle has more carbon dioxide in it than oxygen. This is because the body tissue have used up the oxygen in the blood causing it to become poor in oxygen. The blood need oxygen so that it can be supplied to the whole body and the tissues for energy. The left pulmonary artery send this blood to the

arteries: They carry blood away from the heart and they are under high pressure from

Overall, a few individuals accept, that blood is red when it is oxygenated and that blood in veins is blue when it is not oxygenated. Presumably veins really look somewhat blue through your skin. In fact, the blood in veins is light red, rather than the bright red, oxygenated blood in arteries. The skin and fatty tissue between our eyes and the veins make them somewhat blue. So, if a vein is close to the surface of the skin, most of the blue light will be absorbed, and even though red light doesn't reflect as much, the red light:blue light ratio is high enough to make the vein appear red
