What is the Difference between Veins and Arteries
The circulatory system in the body consists of veins and arteries. Both do the same function of carrying blood from one part of the body to the other but this is the only common thing between them. Otherwise they differ not only in their function but also in nature. Both have to do well to keep the system of the body running efficiently. These blood vessels do not afford to stop working even for a second.
Veins
Veins are the blood vessels that carry blood to the heart from the outer parts. The blood they carry to the heart is de-oxygenated i.e. the blood oxygen is already utilized by the body. When this blood reaches heart, from there it is carried to the lungs for oxygenation and then it is again carried to heart. Veins are very flexible and they collapse when they are out of blood. They have valves that keep the flow of the blood in one direction so that gravity may not harm or disrupt the function.
Arteries
Arteries carry blood from heart to the other parts of the body. The blood they contain is oxygenated and it flows from heart to the outer parts. Arteries have muscles which contract along with the heart beats. The pulse that we feel is that contraction of artery. The outer layer of the arteries is made of connective tissues which go to the middle layer. Arteries are not flexible and they do not have valves.
Veins vs Arteries
Both have the same function of carrying the blood but differ in the nature of the work. Veins carry blood to heart for its oxidation whereas arteries carry the pure full of oxygen blood to the body parts. The blood which is draw from body or any medicine which Is injected into the body is always from the veins not arteries this is because arteries contract and we can feel the pulse while veins do not have this feature instead they have valves which prevent the blood flow on opposite side to prevent the gravity-related harms.
