Retinal veins are larger than retinal arteries. Retinal veins are between 2/3 to 3/4 times larger than the arteries of the retina. Retinal vein are also darker red then the arteries.
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
Your arteries carry blood from the heart to all corners of the body. The aorta is the main artery leaving the heart, with well known branches like the carotid artery (to the head), the femoral arteries (to the legs), the brachial ateries (to the arms). The other main artery from the heart is the pulmonary artery which goes to the lungs to get oxygen.

Retinal veins are larger than retinal arteries. Retinal veins are between 2/3 to 3/4 times larger than the arteries of the retina. Retinal vein are also darker red then the arteries.
In pulmonary arteries, PO2 is around 40 mmHg and PCO2 is around 46 mmHg. In pulmonary veins, PO2 is around 100 mmHg and PCO2 is around 40 mmHg. In systemic arteries, PO2 is around 100 mmHg and PCO2 is around 40 mmHg. In systemic veins, PO2 is around 40 mmHg and PCO2 is around 46 mmHg.
the three blood vessels are the Veins capillaries Arteries the arteries.
the pulmonary artery, coronary arteries and veins, inferior vena cava, branch arteries, and superior vena cava

Cellulose is what surronds veins and arteries.
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
