When blood lacks oxygen, it appears dark red or maroon in color.
Locking the knees for an extended period of time can restrict blood flow to the brain, leading to a drop in blood pressure and a decrease in oxygen supply. This can result in syncope, or fainting, as the brain is not receiving enough blood and oxygen to function properly.
The heart pumps blood by contracting and relaxing in a rhythmic manner. When the heart contracts (squeezes), it pushes blood out into the arteries. This blood then travels through the body, delivering oxygen and nutrients to cells and removing waste products. When the heart relaxes, it fills up with blood from the veins, ready to pump again. This continuous cycle of contraction and relaxation helps circulate blood throughout the body.
The Blood of Christ flower holds religious significance as it symbolizes the blood shed by Jesus Christ on the cross for the redemption of humanity's sins.

When you bleed, your blood appears dark because it lacks oxygen. Oxygen-rich blood is bright red, but when it comes into contact with air and loses its oxygen, it turns dark red.
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
Hemoglobin is the protein in red blood cells that carries oxygen, giving blood its red color.
Capillaries change color as they pass by body cells as the blood they contain loses oxygen. Oxygen-rich blood has a brighter color than oxygen-poor blood.
When blood cells have oxygen they are red, when they have no oxygen they are a darker shade of red.
