How do you distinguish between arterioles and venules?
Arterioles are small blood vessels that carry oxygenated blood away from the heart to the capillaries, while venules are small blood vessels that collect deoxygenated blood from the capillaries and carry it back to the heart. Arterioles typically have thicker walls and are more muscular than venules to help regulate blood flow and pressure, while venules have thinner walls and lower pressure.
What is the function of each blood vessles?
arteries carry oxygenated blood from the heart, to the cells. arterioles do the same thing, but they are small. veins carry deoxygenated blood to the heart. venules do the same as veins, but they are also small. capillaries are the place where the exchange takes place, between oxygenated and deoxygenated.
What is a very small artery that delivers blood to the capillaries?
The blood vessel that only allows one corpuscle to go through at a time is called a capillary.
What do venules do?
it is a part in the heart which reforms the bases of the muscle contamination in the heart.
Do platelets carry gasses such as oxygen and carbon dioxide?
No, platelets do not carry gases such as oxygen and carbon dioxide. Platelets are small blood cells that help with clotting and wound healing, but they do not have a role in transporting gases in the bloodstream. Oxygen is primarily carried by red blood cells, and carbon dioxide is transported in the blood in various forms, including dissolved in plasma and bound to hemoglobin.
What do arteriolie's do?
They are a very small and narrow blood vessel. Smaller than an artery, they carry blood to the capillaries which carry blood to the cells of the body.
What are small tubes that carry blood called blood?
Blood vessels are the tubes that carry blood. The smallest of the blood vessels are the capillaries.
What is the name for the tiny tubes that carry blood?
Capillaries are the tiny tubes that carry blood. These vessel connect small arteries to small veins, and are the site of gas exchange.
Why is capillaries narrow?
Capillaries are very small in size because they need to have a large surface area so they are able to transport blood all around the body. Blood cells must pass in single file through the capillaries as they are so small.
What is the prefix for Capillary?
The prefix for "capillary" is "capill-" which means small or narrow, often referring to small blood vessels in the body.
Which very small tubes carry blood?

Blood vessels in the small intestine carry away?
nutrients
What does the threeoof blood tubes and what do they do?
The three types of blood tubes are arteries, veins and capillaries. Arteries carry blood away from the heart, and veins carry blood to the heart. Capillaries connect small arteries to small veins, and are the site of gas exchange.
Microscopic vessels that carry blood from small arteries to small veins are?
Capillaries are the microscopic blood vessels that connect small arteries to small veins. Blood exchange takes place in capillaries.
What are the functions of arterioles?
Arterioles are small blood vessels that carry oxygenated blood to the body tissues.
What happens in a finger stick test?
A lance, or small needle, makes a small cut in the surface of the fingertip, and a small amount of blood is collected in a narrow glass tube. The fingertip may be squeezed to get additional blood to surface.
What is the small tube that carries blood called?
Capillaries are the smallest tubes that carry blood (blood vessels). They connect veins and arteries.
