| Arteries | Veins |
|---|---|
| Carry blood under high pressure | Carry blood under low or negative pressure |
| Have thick muscular and elastic walls to pump and accommodate blood | Have thin walls – have less muscular tissue than arteries |
What are two functions of the arteries?
Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.

What is the function of artery class 10?
The arteries are responsible for carrying the oxygenated blood away from the heart to different organs. On the contrary, veins carry deoxygenated blood from different organs of the body to the heart for oxygenation.
What is the function of arteries Class 7?
Arteries are the blood vessels which carry blood from the heart to all the parts of the body.
What is the function of arteries veins and capillaries?
The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.
Why is an artery an organ quizlet?
Similarly, organs are defined are being a collection of tissues, which are joined in a structural unit to serve a common function.An artery is made up of several types of tissues including: Elastic tissue – this evens out the pressure changes in the vessel when the heart ventricles contract, by stretching and recoiling …
What are arteries and veins quizlet?
Arteries are thicker due to a higher and more fluctuating blood pressure. Veins are thinner. Peripheral veins have valves to keep blood flowing in one direction toward the heart.
What is artery in human body?
Arteries (in red) are the blood vessels that deliver blood to the body. Veins (in blue) are the blood vessels that return blood to the heart. Deep veins, located in the center of the leg near the leg bones, are enclosed by muscle.
What is the function of the coronary arteries quizlet?
Function of the coronary arteries is to deliver oxygenated blood to the myocardium.
What are arteries veins?
Arteries and veins (also called blood vessels) are tubes of muscle that your blood flows through. Arteries carry blood away from the heart to the rest of the body. Veins push blood back to your heart. You have a complex system of connecting veins and arteries throughout your body.
What is the function of the coronary circulation quizlet?
The coronary circulation provides oxygenated blood to the heart through coronary arteries. Coronary veins return the deoxygenated from the heart to the coronary sinus on the posterior surface of the heart.
What are the function of vein?
Veins are a type of blood vessel that return deoxygenated blood from your organs back to your heart. These are different from your arteries, which deliver oxygenated blood from your heart to the rest of your body. Deoxygenated blood that flows into your veins is collected within tiny blood vessels called capillaries.
What is the function of an artery and vein in the body what specific blood vessels are an exception to that function?
Artery vs Vein.
Arteries carry blood away from the heart, and veins carry blood towards the heart. With the exception of pulmonary blood vessels, arteries carry oxygenated blood and veins carry deoxygenated blood. Arteries have thick walls with muscle tissue.
What are the three major functions of the circulatory system?
The cardiovascular system has three main functions:
- transport of oxygen, carbon dioxide and nutrients.
- clotting of open wounds.
- regulation of body temperature.
What are the functions of arteries veins and capillaries quizlet?
-Lumen of a vein is relatively wider than that of an artery. -Veins have valves to prevent backflow of blood flowing to the heart at low pressure. Allow exchange of substances carried in the blood with the tissues of the body. -Capillaries have a lumen and very thin walls – only the enothelium.
What is the function of veins quizlet?
The function of Veins is to move the blood back towards the heart and their structure is larger and they have valves to help them move blood back to the heart.
What is the function of veins and venules quizlet?
Veins collect blood from all the tissues and organs and return it to the heart. Venules are the smallest vein and collect blood form the capillaries. Describe the structure of a capillary bed.
