You probably cut an atery. Blood has a layer. Pink to red is the levels of danger.
Arterial Blood is Bright Red
Oxygenated blood is bright red, and would only come out of an artery. It will look strikingly different from venous blood which is darker, and what you would generally see if you had a superficial cut.
Yes, it can, when you pop a blood vessel. You can do this by pushing too hard on a vein or artery. Also, when you get a cut it is coming out of a vein or artery.
Not in a human, no. Oxygenated blood is bright red. Deoxygenated blood is a dark red.
the blood is bright red because of the oxygen from the air
thin, bright red blood means that your platelets are low.
Bright red blood is a sign of highly oxygenated blood. Pain, fast pulse rate and rapid respirations are generally the cause. Bright red blood is also a sign that an artery has been severed. Blood is red because it contains a chromophore (colored compound) called heme. The electronic structure of heme is such that it can reversibly bind certain other molecules, one of which is oxygen. The oxy-heme complex is bright red. If the blood came from an artery, it was probably already bright red. If it came from a vein, the heme will be a sort of dark purplish-red, but as soon as it hits the oxygen in the atmosphere, it will bind and form the bright red oxy-heme complex, so regardless of where you cut yourself, the blood is going to be bright red. When you give blood at a blood bank, the blood is drawn from a vein, and flows into a bag which keeps the oxygen out. This blood will be the dark purplish-red color of the deoxygenated heme.
It is bright maroonish red.
red blood cell
Red. bright (or blood) red.
The lungs carry the oxygen. The pulmonary artery sends blood to the lungs to be oxygenated, where it turns red. Blue blood is not oxygenated, red is. If you cut yourself, you will only see red blood though. Then the pulmonary vein brings it to the left atrium.
