Blood vessels.
- The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium.
- The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream.
- The pulmonary veins bring oxygen-rich blood to the left atrium.
Which blood vessel carries the most highly oxygenated blood?
The left side pumps oxygenated blood (high in oxygen and low in carbon dioxide) to the organs of the body. Deoxygenated blood enters the right atrium from the vena cava.
The heart.
| Blood vessel | Function |
|---|---|
| Aorta | Carries oxygenated blood from the heart around the body. |
| Hepatic artery | Carries oxygenated blood to the liver. |

Which vessel has lowest oxygen concentration?
Coronary sinus carries blood with least oxygen concentration. Pulmonary artery also carries the same, but in cases of patent foramen ovale there are chance of mixing up of oxyenated blood. So coronary sinus almost always carries deoxygenated blood.
Which vessel has highest pressure?
Rank the blood pressure in the following vessels from highest to lowest: veins, capillaries, arteries, arteriol, venule.
Which blood vessel has the highest concentration of urea?
Name the blood vessel that has the highest concentration of urea after a protein-rich meal. The liver does the job of breaking down excess amino acids, which are a result of the breaking down of the proteins, into urea. The hepatic vein, which leaves the liver, then carries this urea out of the liver.
Which vessels do not carry oxygen rich blood?
No, the pulmonary veins carry oxygen rich blood and the pulmonary arteries carry oxygen poor blood.
Which type of blood vessel is the smallest?
Capillaries, the smallest blood vessels. Metarterioles, a vessel that links arterioles and capillaries. Venules, a blood vessel that allows deoxygenated blood to return from the capillary beds to the larger blood vessels called veins.
Which blood vessel is the largest?
aorta
Which blood vessel has the smallest diameter?
capillaries
Which type of vessel has the lowest blood pressure?
Important: The highest pressure of circulating blood is found in arteries, and gradu- ally drops as the blood flows through the arterioles, capillaries, venules, and veins (where it is the lowest).
Which blood vessel is most suited for gas exchange?
1. Arteries- these carry “oxygen rich” blood away from the heart, except in the case of the artery to the lungs. 2. Capillaries- these are the sites of gas exchange between the tissues.
What country has the lowest blood pressure?
Prevalence is lowest in rich Western and Asian countries, including South Korea, America and Canada. In only 36 countries high blood pressure is more common in women than in men.
What blood vessel contains the least oxygen?
Blood vessels.
- The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium.
- The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream.
- The pulmonary veins bring oxygen-rich blood to the left atrium.
Which blood vessel contains the highest concentration of carbon dioxide?
most oxygen would be the vessel which has just left the lungs which I believe is the pulmonary vein. most CO2 would be pulmonary artery. the highest tempreture is a hard one, but if I was to guess it would be the aorta because of the high blood pressure and the friction with the walls.
Which vessel will have the highest concentration of amino acids after a meal?
Hepatic portal vein would contain the highest concentration of amino acids and glucose soon after a meal.
On which side of the heart is the muscular wall the thickest?
The walls of the atria and the auricles contain parallel bundles of muscles called pectinate muscles. The two lower chambers are the ventricles, which have thick walls and force blood out of the heart by way of arteries The left ventricle has the thickest walls because it is the major pumping chamber of the heart.
Does everyone have the same amount of veins?
In my estimation the answer is pretty much the same. The problem is that we all have about 30 feet of the major arteries and veins. The estimate for the average adult is 60,000 miles of capillaries. Of course bigger people have more capillaries, and smaller people have less.
Do veins transport oxygen rich blood?
The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
What are the thinnest arteries called?
They are the smallest and thinnest of the blood vessels in the body and also the most common. Capillaries connect to arterioles on one end and venules on the other.
What are the blood vessels from largest to smallest?
Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries. Capillaries are so small they can only be seen under a microscope.
Which vessel type has the largest diameter?
Types
- Arteries. Aorta (the largest artery, carries blood out of the heart)
- Arterioles.
- Capillaries (the smallest blood vessels)
- Venules.
- Veins. Large collecting vessels, such as the subclavian vein, the jugular vein, the renal vein and the iliac vein.
Which type of blood vessel has the thickest walls?
Structure of blood and blood vessels
| Artery | Vein | |
|---|---|---|
| Wall | Thick, muscular | Thinner |
| Lumen | Small | Large |
| Other features | Thick muscular walls to withstand blood flowing at high pressure as it leaves the heart; the largest artery is the aorta | Contain valves to prevent back flow of blood |

Why is the aorta the largest blood vessel?
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The pulmonary arteries carry oxygen-poor blood from the heart to the lungs under low pressure, making these arteries unique.
What are the thinnest veins called?
Capillaries feed the heart: They are the tiniest vessels that bridge the smallest arteries to small veins called venules. From there, blood passes into veins that serve as tributaries to larger veins before entering the heart. Capillaries are the smallest, thinnest blood vessels in the whole body.
