What is the difference between veins and nerves?
There is a big difference, both structural and functional between the veins and the nerves.
Structural differences:
1. The nerves are composed of nerve cells called NEURONS. A neuron is composed of the body which has NUCLEUS inside, long extension branch called AXON (which is surrounded by MYELIN in some nerves), short extension branches called DENDRITES and SYNAPTIC TERMINAL.
2. A vein is a tubular organ composed of 3 layers:
a) tunica externa (epithelial cells)
b) tunica media (smooth muscle cells)
c) tunica interna (endothelial cells)
Functional differences
1. The nerves function is to carry information from the receptor (f.e. skin) to the brain and from the brain to the effector (f.e. striated muscle). This is called reflexive arch.
2. The definition about a vein is: a blood vessel that transports blood to the heart.
Both arteries and veins are types of nerves

What is the difference between veins and arteries?
- Arteries carry purified blood from the heart to different parts of the body. Veins carry unpurified blood to the heart from different parts of the body.
- Arteries have thicker walls compared to the the veins.Arteries have more muscles. Only veins have valves. Arteries have a smaller lume.
- An artery carries blood away from the heart, while veins transport blood to the heart.
- The difference is that an artery brings blood to the body and a vein takes blood to the lungs.
- Arteries and Veins are part of the circulatory system, where arteries carry the blood from the heart to the organs, and the veins carry it from the organs to the heart again.
- Arteries carry blood away from the heart to the other parts of the body. Arteries also have thicker walls as the blood pressure is much higher having a closer proximity to the heart. Veins carry the blood back from the other areas of the body to the heart. Simply put, an artery carries blood out of the heart, and a vein carries blood into the heart. Arteries are under more pressure than veins. Arteries contract to help push blood through whereas blood flow through veins is passive.
Veins- oxygen-poor blood that is returning to the heart
Arteries- oxygen-rich blood that is going to the cells
I am pregnant as well and found this information online, hope it helps! I would ask your doctor about it just to be safe though. Many women first develop varicose veins or find that they get worse during pregnancy. As your uterus grows, it puts pressure on the large vein on the right side of your body (the inferior vena cava), which in turn increases pressure in the leg veins. Veins are the blood vessels that return blood from your extremities to your heart, so the blood in your leg veins is already working against gravity. The amount of blood in your body increases when you're pregnant, adding to the burden on your veins. And your progesterone levels rise, causing the walls of your blood vessels to relax. You're more likely to get varicose veins if other members of your family have had them. Being overweight, carrying twins or higher multiples, and standing for long periods can also make you more susceptible. The good news is that varicose veins tend to improve after you give birth. Well okay your telling me that the chance of this being pregnancy is low and that it is due to genetics or something else. Okay, I love these little know it alls that just think that they are doctors, and say that there is no possible way for it to be what it is. I took a test and wullah I am and my doctor says that this is very normal in pregnancy and a lot of smaller women like myself have it immediately in pregnancy. Before you go telling someone that more than likely it is from something else GO GET A P.H.D. These questions are intended for those with the same problem or whom have already had experience in the subject. Not those of you who think you know all and try to be a doctor. Oh yeah and I forgot to add, no one in my family has vericose veins either, I am a house wife, and I am up and down all day to the long period of siting/standing, etc...whatever you had said.
What circulatory problem leads most directly to the formation of varicose veins?
malfunctioning valves in veins
your veins look blue because your blood has no oxygen, when your blood is oxygenated it is red and when it is deoxygenated it is blue. veins carry blood toward the heart and are often blue while arteries carry blood away from the heart and are filled with oxygenated blood.

Deoxygenated blood leaves the kidneys through the renal veins.
