What are the small arteries of the circulatory system?
As arteries become smaller to pass through narrower places, they are known as arterioles. Arterioles then branch out into capillaries.
What do you call small artery?
a vein could be considered a smaller artery, they are smaller and take blood to the heart and arteries take it to the heart.
How does circulate around the body?
Left ventricle-Aorta-smaller arteries-Arterioles-Capillaries-Venules-Vena Cavae (inferior and superior vena cava)-Right atrium-Right ventricle-Pulmonary artery-smaller arteries-Arterioles-Capillaries of the Lungs-Pulmonary veins-Left atrium
Arteries branch into smaller vessels called?
Arteries - arterioles - capillaries - venules - veins - back to the heart...

The smallest blood vessel?
The smallest arteries of the human body are the arterioles, which supply blood into the capillary network from the main arteries (artery-->arteriole-->capillary-->venule-->vein). They hold plasma and filtrates, and are usually only wide enough to hold a single red blood cell at a time (in some cases, they are smaller than a RBC).
Do capillaries connect arteries and viens?
No, arteries carry blood away from the heart, veins carry blood back to the heart, and capillaries are where blood disperses throughout areas in the body. capillaries are sort of in between, but not really.
What artery carries oxygenated blood?
The aorta (largest artery in the body) carries oxygenated blood from the heart to the body. From the aorta, the oxygenated blood will eventually travel through smaller and smaller arteries in your body, until eventually entering the capillaries to be delivered to the desired area.
What are arterioles and venues?
== == Arterioles are very tiny arteries. In some areas of the body there are places where arteries and veins come together in tiny formations to swap oxygenated blood (in the arteries) for unoxygenated blood (in the veins). (As the veins get smaller they become capillaries, then caprioles.) The arteries are responsible for delivering blood with oxygen from the lungs to the rest of the body. Veins carry the "used blood" with no oxygen back to the heart where it passes into the lungs and picks up more oxygen and gets rid of the carbon dioxide that builds up as our bodies use the oxygen. The arterioles and caprioles come together to swap this blood. Well the above might be true but...... Arterioles are small arteries that deliver blood to the Capillaries. While Venules are small veins that are connected to the Capillaries.
Part of the heart that squeezes blood into the arteries?
Oxygenated blood leaves the left side of the heart through the aorta,the largest artery and then to smaller arteries.Deoxygenated blood leaves the right side of the heart through the pulmonary artery then to arterioles and capillaries.
What are the differences between arteries arterioles veins venues capillaries?
The Main Differences:Arteries:Arteries carry oxygenated blood, and are very narrow but thick, to enable them to maintain a high blood pressure, whilst also withstanding that pressure. Veins:Veins carry de-oxygenated blood, and are very dilate and thin, as they do not need to carry blood at such high pressures. Different Branches:Arteries and Veins:The circulatory system branches off into smaller and smaller parts. Firstly the arteries and veins, the largest of the blood vessels, carry large volumes of blood to the necessary parts of the body.Arterioles and Venules:These then branch off into arterioles and venules, which are smaller in diameter, and so carry smaller volumes of blood, however, they are more numerous. Arterioles and venules effectively surround the organs and tissues, to ensure that the whole of the organ/tissue can receive oxygen or remove carbon dioxide etc. Capillaries:These arterioles and venules then branch off into tiny capillaries, which are only thick enough to allow one red blood cell through at a time. This means that transport through the capillaries is slower, and there is more time for diffusion, osmosis etc. to take place. The capillaries are even more numerous than the arterioles and venules, in fact, they are spread in between every few cells. This allows for effective diffusion between the blood and the tissue, as the substances do not have to travel very far.The capillary walls are also only one cell thick, which allows for efficient diffusion, as the substances being transported do not have to travel very far.
Blood moves from arteries into what?
After blood leaves the arteries, it enters smaller blood vessels called arterioles which help supply the body with blood and then they break down into even smaller vessels called capillaries which then carry the oxygenated blood to the tissues, organs and all cells of the body. Then after the body uses up all the oxygen, the blood becomes deoxygenated which then enters venules and then veins which lead up back to the vena cava of the heart. It then enters the right atrium then passes through the tricuspid valve and then enters the right ventricle, then leaves the heart via the pulmonary artery which enters the lungs to oxygenate the blood.
