Blood entering the heart from Superior vena cava and Inferior vena cava is "dirty". Bloold going through Pulmonary artery is 'dirty" and is "cleaned" (oxygenated) in the lungs. Blood entering the heart via pulmonary vein and leaving via aorta is clean.
Fresh blood is brilliant red, but as it clots it will turn brown.
When the blood is going to the heart it is blue. When it is going away from the heart, it is red.
The heart of a calf is about the same color as yours. It is darker and browner than blood.
Blood is bright red when it returns to the heart from the lungs. It is darker red when it returns to the right atrium from the systemic circulation.
Veins are darker than arteries because they have thin walls, and the darker blood shows through them more easily. Arteries are lighter in color because they have thicker walls containing connective tissue which is lighter in color in preserved material. The veins probably look wider because they collapse when the heart stops beating. When they collapse, they flatten out, making them wider.
All blood is red, regardless of where it is in the body. Oxygenated blood and deoxygenated blood have slightly different shades, with deoxygenated blood being darker and oxygenated blood brighter.
