Everybody's answer above is correct. They only neglected to mention that the reason the blood does not flow backward is, the veins have one-way valves. When the heart contracts the valves in the veins open and the blood flows forward. When the heart expands to receive more blood, the valves in the veins close so that the blood does not flow back from the way it came.

5 days ago my husband told me he thought he had a hemorrhoid. He is 33, 5 9 and 155lbs, and is healthy. He was not constipated, and has always had normal daily stools . It seems to have gotten worse the past 5 days. He is using hemorrhoid cream, baby wipes to wipe, and taking epsom salt baths. Today when he stood up at work he felt something come out of his anus , and found blood on his underwear when he went to the bathroom. I know it is normal to see blood when you wipe or in the stool, but is it normal to have blood flow out of nowhere like that? How long does it take for hemorrhoids to clear up, and at what point should he see a doctor? Would a family doctor do, or does he need to see a specialist?
I have essential hypertension, and I just checked my BP. It s pretty high...at what point (diastolic/systolic) should I contact a doctor? I m on Micardis HCT, but it doesn t seem to be working right now. Thanks. Just re-checked my BP, it s 175/115. Well, it is being treated. I see my Doctor regularly, but tonight it seems to be too high for whatever reason. I m just wondering if there s anything I should do right now, or if it ll be fine until tomorrow. http://i18.photobucket.com/albums/b138/jgarrey/p_00363.jpg Systolic is down by almost 20 points, but diastolic isn t moving?? WTF does that mean?? :/
