Arteries are the blood vessels that carry blood away from the heart where it branches into even smaller vessels. The main differences between the veins capillaries and arteries all parts of the circulatory system are as follows.

Blood supply at tissue level. Blood returned to the heart. Thick middle layer of involuntary muscle to increase or decrease diameter.
One layer of endothelium with very small diameter. Thin middle layer as pressure is reduced. Inner layer of endothelium which reduces friction.
Only endothelium layer present. Arteries are defined as the blood vessels that carry oxygenated blood from the heart to the tissues. On the other hand veins are defined as the vessels that carry deoxygenated blood from organs back to the heart.
On the other hand capillaries are defined as the smallest vessels that link arteries and veins. The difference between arteries capillaries and veins. The main differences between the veins capillaries and arteries all parts of the circulatory system are as follows.
Capillaries have no muscular walls. Capillaries are the thinnest ducts of these three categories by far. On the other hand its walls are not associated with muscular tissues.
In general veins have thinner walls than arteries. Certain medium and large veins in lower limbs have valves present in them to prevent the backflow of blood and maintain the unidirectional flow of blood from the organs to the heart movement that goes against the gravitational force. Arteries are larger and carry oxygenated blood from the heart throughout the body.
Pulses are obtained from arteries. Veins carry unoxygenated blood back to your heart. The lack of oxygen turns the blood dark red making it appear purpleblue through the skin.
Capillaries are microscopic vessels that connect arteries and veins. Arteries generally carry oxygenated blood except pulmonary artery. Capillaries are lined by only tunica interna which is made of porous endothelium.
The pores in the capillary endothelium simple squamous epithelium allow amoeboid white blood cells shown in black in the diagram to travel into tissue space by a process called diapedesis where the WBCs help in. Arteries Veins and Capillaries. The blood from the heart is carried through the body by a complex network of blood vessels see the figure below.
Arteries take blood away from the heart. The main artery is the aorta that branches into major arteries that take blood to different limbs and organs. These major arteries include the carotid artery.
There are 3 main kinds of blood vessels arteries veins and capillaries. Arteries carry blood away from the heart. They divide again and again and eventually form very tiny vessels called capillaries.
The capillaries gradually join up with one another to form large vessels called veins. Veins carry blood towards the heart. The capillaries connect the two types of blood vessel and molecules are exchanged between the blood and the cells across their walls.
Arteries carry blood away from the heart. Veins function to take blood to the heart arteries function to transmit blood away from the heart to the body and capillaries connect the systems of blood vessels in the cardiovascular system. Veins carry blood under low pressure from the capillaries and return the blood to the heart.
The vein walls have thinner muscular walls than arteries and have a wider internal diameter. Now remember the capillaries contain low pressure blood to pass on to veins so the veins dont need thick walls like arteries. But without high pressure to keep the blood moving they will need a way to keep blood moving in the right direction often against gravity - ie.
The key difference between capillaries and veins is that capillaries connect arterioles and venules and involves in microcirculation while veins carry deoxygenated blood from organs and tissues back to the heart. Usually oxygenated blood travels through main arteries divides into specific arteries designed for the organs and tissues further. Arterioles are smaller arteries.
Veins return blood back to the heart. Venules smaller veins. Capillaries- smaller blood vessels that link arteries and veins together.
The heart as already well known is the pump of the system that sends out blood in arteries as arteries carry blood away from the heart. In this video I explain the key structural and functional differences between the 3 major blood vessels. Arteries veins and capillaries.
Arteries veins and capillaries part 1life processes biology class 10transportation in animals class 7. Circulatory System Artery Vein and Capillary In this video I outline the structural and functional differences between the three blood vessels in the body. Compare and contrast structure and function of veins arteries and capillaries.
Arteries have a much thicker wall to withstand the high pressure. Arteries are the blood vessels that carry blood away from the heart where it branches into even smaller vessels. Finally the smallest arteries called arterioles are further branched into small capillaries where the exchange of all the nutrients gases and other waste molecules are carried out.
