What colour is human blood when it's inside ur body?

Answer 1

blue inside when air hits turns red?

Answer 2

I am working on my Master's degree in Health Sciences. And blood is never blue in a Human beings body it is either red or dark red. It is a common misconception because of the way our skin filters the light and tissue that makes up our veins showing the veins as blue even though oxygenated or not the blood is red.

Answer 3

Depends on its oxygen content, the more oxygen the more bright red. Among these there are a variety of saturations possible. Bright red is due to Oxyhemoglobin and dark red is due Carboxyhemoglobin. Usually bright red blood is in arteries and dark red in vein, except in the case of pulmonary vein and artery. But in a person with emphysema both artery and vein blood are dark red and in a person with anxiety and hyperventilation both are bright red.

Answer 4

Bright red inside arteries (oxygenated blood havin.g been carried from the lungs to the heart and then to other areas of the body) and darker red inside veins (de-oxygenated blood having been carried from the body systems to the heart and then to the lungs)

Answer 5

same colour inside as outside RED!
(The more oxygen in the blood the lighter the shade - hence arterial blood lighter than venous blood)

Answer 6

Bright red in the arteries (outgoing), and dark red in the veins (returning)

Answer 7

Bright red in arteries and dark red in veins

Answer 8

Still red - just the shade varies depending on location.

Answer 9

Answer 10
