What Is Arterial Blood?

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

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

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

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

The blood travels through arteries and then through Arterioles and finally through capillaries until they reach the Alveoli air sacs within the lungs. This is where gas exchange occurs. Then the oxygenated blood returns back to the heart through

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

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.

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

The right side of the heart, has the right atrium and ventricle where blood exchanges its oxygen and nutrient for the waste material of the cells and then returned to right side of the heart.

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

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

2) When this is full a valve opens and blood flows into the right lower ventricle.

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

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
