Why is my blood so bright in color?

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. It is still red but will be darker.

What is the healthiest blood?

Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).

Which blood is more darker?

Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).

Is dark and thick blood good?

When blood is thick, it can hinder the movement of oxygen, hormones, and nutrients throughout the body, preventing them from reaching tissues and cells. This can cause low oxygen levels in the cells and lead to hormonal and nutritional deficiencies.
