The veins have small valves that allow the flow in only one direction, so that muscle movement in the legs act to push the blood towards the heart. This is why it is so important for people to walk or shift their weight when standing for a prolonged period.

How can people with heart condition suffer swollen feet?
You are talking about "heart failure". There are two kinds. Edema (swelling) in the feet happens when the heart is having trouble pumping blood out of the body and to the lungs for oxygenation. Because of this, fluids build up in the extremities. Sometimes the heart has trouble pumping blood out of the lungs and back into the body's general circulation. In this case the build-up of fluid is in the lungs.
How does blood defy gravity and circulate from your toes back up to your heart?
You may not know this but as well as pumping, your heart also sucks blood back into its' chambers like a vaccum which is how your blood gets returned to your heart.
What blood vessels carries oxygenated blood to the heart?
The coronary arteries carry blood to the muscle that makes up the heart but this blood comes directly from the large artery called the aorta.Otherwise arteries always carry blood way from the heart and veins carry it back. As far as if it they carry oxygen or not, veins carry blood back from the body without oxygen and back from the lungs with oxygen.
Where do the right side of a bird's heart pump blood to?
The right side of the heart pumps blood to the lungs to pick up oxygen. From the lungs it goes back to the left side of the heart, which pumps it out to the rest of the body. Blood then returns to the right side of the heart and starts the cycle over.
When you are standing on your head the blood goes to your head so when you are standing up straight why doesn't the blood go to your feet?
Your heart pumps blood to all organs in your body. when you stand upright blood will be pumped to your feet with much less effort than standing on your head. When you are under normal gravitational force, even though gravity has an effect on blood flow, your blood circulation is totally controlled by your heart. So when you stand on your head blood will also be pumped to your feet.
Which force must the flow of blood overcome as it moves from the feet back up to the heart through the veins?
Gravity

Does blood capallaries have valves?
peripheral veins have valves to help get the blood back up to the heart but arteries do not because they have enough pressure from the pumping of the heart to get the blood out to the body.

Why do they say horses have 5 hearts?
Because the 4 feet, when kept in a natural barefoot state, pump blood back up to the heart as they expand and contract with each step. When the foot is set down on the ground, it expands and fills with blood. When the foot is picked up, it contracts and the blood is sent back up the hoof to the heart. Roughly a liter of blood is pumped through the body between each 4 feet every 20 strides. So some may call the feet the other four hearts. HOWEVER, with horseshoes, the hoof cannot expand, therefore reducing circulation, straining the horses heart more since it lost the use of its "four hearts" and that is part of the reason there is this natural horse, barefoot movement going on.
