Why period blood is green?
It is normal to see a greenish tint in the menstrual discharge on the pad; it just means that’s older, drier blood. If your period is light and you change your pads less often, you are more likely to see this darker colored blood.
Is human blood blue?
Blood pumped directly from the heart is oxygen rich and bright red. As the blood circulates the body and oxygen is removed by tissue, the blood grows darker. For that reason, blood returning to the heart and lungs often has a dark red appearance. But it’s never blue.
What is a healthy blood color?
As blood leaves the heart and is oxygen-rich, it is bright red. When the blood returns to the heart, it has less oxygen. It is still red but will be darker. This darker red appears blue because of how light travels through the skin.
Why is my discharge pink?

What does Brown blood mean?
When blood leaves the body quickly, it’s usually a shade of red. When the flow slows, the blood has time to oxidize. This causes it to turn brown or even black in color. If you see brown blood at the beginning or end of your period, this is completely normal.
What does purple blood mean?
Oxygenated (arterial) blood is bright red, while dexoygenated (venous) blood is dark reddish-purple. The difference is color results from the electronic state of the iron ion (ferrous vs ferric), which in turn influences the π → π* and n → π* electronic transitions of porphyrin and hence its optical characteristics.
What color is venous blood?
It is the blood in the veins that gives them color. Furthermore, the blood in human veins is also not blue. Blood is always red. Blood that has been oxygenated (mostly flowing through the arteries) is bright red and blood that has lost its oxygen (mostly flowing through the veins) is dark red.
What are 3 types of bleeding?
There are broadly three different types of bleeding: arterial, venous and capillary.
What is dark blood a sign of?

Is purple period blood normal?
These really dark periods are a sign that your uterine lining has become even more stagnant than the rusty brown ones that we covered above. Blue and purple periods may also be a sign of poorly oxygenated blood or colder than normal body temperatures, which can result from hypothyroid disorders.
What makes the blood look red?
Human blood is red because of the protein hemoglobin, which contains a red-colored compound called heme that’s crucial for carrying oxygen through your bloodstream. … That’s why blood turns bright cherry red when oxygen binds to its iron. Without oxygen connected, blood is a darker red color.
What does deoxygenated blood mean?
The right side pumps deoxygenated blood (low in oxygen and high in carbon dioxide) to the lungs. The left side pumps oxygenated blood (high in oxygen and low in carbon dioxide) to the organs of the body. Deoxygenated blood enters the right atrium from the vena cava. Blood moves into right ventricle.
