What Color is the Blood Inside Your Body?
What is Blood?
Blood is a bodily fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. Blood is composed of plasma, red blood cells, white blood cells, and platelets.
What Color is Blood?
The color of human blood ranges from bright red when oxygenated to a darker red when deoxygenated. It owes its color to hemoglobin, to which oxygen binds. The color of deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to hemoglobin in the cell.
What Color is Blood Outside the Body?
Blood appears red to the naked eye when it leaves the body. The reason why it looks red is because of the hemoglobin inside the red blood cells, which contains the iron-rich protein that gives blood its red color.
What Color is Blood Inside the Body?
Blood inside the body is actually a brighter color, closer to a scarlet or a deep crimson. This is because the hemoglobin molecule is carrying oxygen, which makes the blood inside the body brighter in color.
Conclusion
The color of human blood can range from bright red to a deeper red, depending on whether the hemoglobin is carrying oxygen or not. Blood outside the body appears red to the naked eye, while blood inside the body is actually brighter in color.
