What does it mean if you have a blood shot eye and can see all your veins?
== == The eye has been irritated by something. Redness is a sign of a unhappy eye, one that has been exposed to too much of something, such as dust, wind, lack of sleep, or too much alcohol drinking. Other causes could be exposure to welding flash, chemical fumes, or even harsh shampoo or soap. Treatment is simple.........warm water bath of the eye, with repeated applications of warm water. Cover the eye, and rest in a dark place, with BOTH eyes closed for an hour at least. Conjunctivitis is the technical term for red eyes. It can also be the result of allerfies, a virus like a cold, or caused by a bacteria like "Red Eye," an irritation or injury, or a serious infection. If you wear contacts remove them until the condition is entirely cleared up. If you normally wear eye makeup, discontinue and discard it. I would use eye drops rather than plain water. Often children bring bacterial "Red Eye" home from school with them. It is spread by hand contact, and can effect all members of the family. Red eye is characterized by redness and a discharge from the eye. Your family doctor can treat Red Eye with mild antibiotic drops. If the condition persists more than 1 day, or you have pain, or the eye tears excessively or is sensitive to light, or the redness is growing worse, I would see an optometrist ASAP. Don't trust your family doctor to treat eye conditions. I did, and almost lost an eye because he mis-diagnosed a serious eye infection as "just irritation from your contacts."
While most veins carry dark CO2 rich blood, three exceptions are the pulmonary veins which return oxygenated blood to the heart from the lungs, the portal veins from the digestive organs, gall bladder, and spleen to the liver, and the umbilical veins which carry blood from the fetus to the mother's placenta.
No. (Not counting the pulmonary veins) the least "deoxygenated" blood is in the renal veins and the jugular. (Neither the brain nor the kidneys use up all the oxygen in their blood supply.) Blood flow to the skin is sometimes controlled by temperature - heat to be lost - and MAY be less desaturated.
The blood flows through your body, this happens by the heart pumping the blood into the veins and the veins lead the all around your body. When the veins have done there job the artieries carry the blood back through the body and back to the heart. It is like a circle through the veins the through the artieries and to the heart. And lets put it this way : if it didnt youd be…
pulmonary vein carries oxygenated blood to heart All the vessels that carry blood back to the heart are called veins, all veins carry deoxygenated blood to the heart but pulmonary vein carries oxygenated blood because blood becomes oxygenated in lungs Some veins carry the blood from an organ to the other organ then to the heart. These are called portal veins such as hepatic portal vein and (in reptiles, amphibians and aves) renal portal vein.
