It is returning from the body's tissues and lower is oxygen. Oxygen causes the blood to be red like rust. The lower the amount of oxygen the less red the blood is.
the blood entering the right atrium is deoxygenated blood returning to the heart from the rest of the body. from there it goes to the right ventricle into the lungs where it picks up oxygen. from the lungs it enters the left atrium then into the left ventricle. the left ventricle then pumps the blood through the aorta and into the body.
If blood appears dark, that is an indicator that it is not fresh. If a person is seeing dark blood in their urine or stool, they should see a doctor immediately. It is possible that there is a serious problem.
Bright red blood is called frank blood, its fresher. Dark red blood is older blood that has been sitting for a while. The colour of fresh blood, say from an open wound, can be different due to variances in the number of red blood cells that person has. why this blood dark red? The amount of haemoglobin (red blood cells) that are in a person can differ slightly, this may cause some peoples blood to be darker than others if its fresh, otherwise see above...
Yes-a sort of dark reddish / brown colour
The determination of blood's color will depend on if there is oxygen in the blood or not oxygenated blood is a dark red color, the same color of the blood that comes out of am open scratch, Or Blue if it has little to no oxygen at all
Blood entering the right atrium is blood returning from the upper and lower body and it has been to the cells and given up all its oxygen. This is sometimes called blue blood and is very dark in colour. [A high oxygen content would cause it to be bright red]. In place of oxygen, it is now carrying carbon dioxide and this blood will enter the right side of the heart where it will be pumped a short distance to the lungs. The carbon dioxide will be exchanged for oxygen and this red blood is then pumped back to the heart, only this time it arrives at the left side, the left atrium, then into the left ventricle where it is pumped all around the body. Hope this helps.
The right side of the blood receives deoxygenated blood from the systemic (body) circulation. The right atrium receives blood from the systemic veins and pumps it into the right ventricle. At that point, the right ventricle pumps that blood to the lungs.
the blood entering the right atrium is deoxygenated blood returning to the heart from the rest of the body. from there it goes to the right ventricle into the lungs where it picks up oxygen. from the lungs it enters the left atrium then into the left ventricle. the left ventricle then pumps the blood through the aorta and into the body.
Deoxygenated blood enters the right atrium via the vena cava, then passes through the tricuspid valve to the right ventricle. The blood is then pumped via this ventricle via the pulmonary arteries to the lungs to pick up oxygen. Oxygen-rich blood returns to the left atrium of the heart via the pulmonary veins and passes via the mitral valve to the left ventricle. This powerful pump then sends the blood through the aortic valve to the aorta and on to the entire body to nourish all living tissue and cells

Dark Blood was created in 1993.
Dark red blood is oxygen-poor. Bright red blood is oxygen-rich.
No there is not blood
My blood colour is black

De-oxygenated blood is dark red. Oxygenated blood is bright red. Both enter the heart- the former enters the right heart; the latter enters the left heart.
