Why is my blood so thick and dark?
Thick blood is caused by heavy proteins, or by too much blood in the circulation. Too many red cells, white cells, and platelets will result in blood thickening. Another cause is an imbalance in the blood clotting system.
What is oxygenated and deoxygenated blood?
Oxygenated blood refers to the blood that has been exposed to oxygen in the lungs. Deoxygenated blood refers to the blood that has a low oxygen saturation relative to blood leaving the lungs. The oxygenated blood is also called arterial blood. The deoxygenated blood is also called venous blood.
What is the color of deoxygenated blood?
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. Anyone who has donated blood or had their blood drawn by a nurse can attest that deoxygenated blood is dark red and not blue.
Why is my blood so bright red?
Why? 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. Heme contains an iron atom which binds to oxygen; it’s this molecule that transports oxygen from your lungs to other parts of the body.
Why is my blood bright red and thin?
Some people have what is called thin blood. The condition means they have too few platelets, a part of the blood that helps it clot. Thin blood has few symptoms, the main ones being excessive bleeding and bruising.

Is thick blood good?
If you have thick blood, you’re at greater risks for blood clots, both in your veins and arteries. Blood clots in your veins will impact blood flow to key areas of your body. Without enough blood flow, tissues can’t survive. If you think you may have a blood clot, seek immediate medical treatment.

Does blood color mean anything?
Blood in the human body is red regardless of how oxygen-rich it is, but the shade of red may vary. The level or amount of oxygen in the blood determines the hue of red. As blood leaves the heart and is oxygen-rich, it is bright red. When the blood returns to the heart, it has less oxygen.
Does deoxygenated blood go to the heart?
Deoxygenated blood from the lower half of the body enters the heart from the inferior vena cava while deoxygenated blood from the upper body is delivered to the heart via the superior vena cava. Both the superior vena cava and inferior vena cava empty blood into the right atrium.
Why is oxygenated blood important?
Arteries carry oxygenated blood (blood that has gotten oxygen from the lungs) from the heart to the rest of the body. Blood then travels through veins back to the heart and lungs, so it can get more oxygen to send back to the body via the arteries.
