Explanation:

Arteries are responsible for transferring blood to organs, traveling far from the heart, when veins space responsible for carrying blood ago toward the heart. Arteries generally carry oxygenated blood to provide oxygen come organs, and veins generally carry deoxygenated blood ago to the heart for re-oxygenation. The singular exceptions room the pulmonary arteries and also pulmonary veins. The pulmonary arteries still travel away from the heart, however carry deoxygenated blood from the right atrium to the lungs. The pulmonary veins still travel toward the heart, but carry oxygenated blood native the lung to the left atrium.

You are watching: Veins always carry deoxygenated blood.

Example concern #2 : understanding Circulatory vessels


Which of the complying with statements about the circulatory device is false?


Possible Answers:

The ideal ventricle pumps blood come the lungs


Veins constantly bring deoxygenated blood earlier to the heart


The worse vena cava empties blood right into the ideal atrium


Blood will constantly travel native arteries come capillaries, and then right into veins


Correct answer:

Veins always bring deoxygenated blood back to the heart


Explanation:

A usual misconception is that veins constantly carry deoxygenated blood. Veins constantly return blood to the heart, but the pulmonary veins room bringing oxygenated blood back to the love so that it may be pumped come the body"s tissues. Deoxygenated blood travels through the right ventricle to the pulmonary arteries. In the lungs it is reoxygenated, then went back to the heart in the pulmonary veins.

Example concern #3 : expertise Circulatory vessels


What blood vessel form contains the highest possible pressure?


Possible Answers:

Arteriole


Vein


Artery


Capillary


Correct answer:

Artery


Explanation:

Blood is able to flow through the blood vessels because of pressure caused by the pump of the heart. The press is the biggest in vessels simply leaving the love (arteries), and also decreases as the blood ship get more away from the heart. Veins have actually the lowest pressures the end of every the blood vessels.

Example inquiry #4 : expertise Circulatory ship


Which that the following is true that arteries?


Possible Answers:

The walls of arteries and veins are about the very same thickness in a offered tissue


Their special walls space due entirely to the bulk of elastic fibers in the center layer


Arteries absence an endothelial layer


Vein walls space thicker than arteries due to the fact that veins must pump blood increase from the reduced body


Their walls room thick and muscular contrasted with veins


Correct answer:

Their walls are thick and also muscular contrasted with veins


Explanation:

Arterial walls have actually three distinctive layers: an within smooth endothelium, a hefty coat of smooth muscle cells and also elastic fibers, and a looser outer layer of connective tissue. Arteries space uniformly recognizable as robust, thick-walled structures compared with surrounding veins.

Although part veins have actually muscular yarn in their walls (for example, those in the legs), this class of cells is thin and also often incomplete. Instead of muscle to against gravity, veins normally use valves to stop blood from flowing backward. Arteries, veins, capillaries, and the love chambers all have actually an endothelial layer.

What vascular structure which carries oxygenated blood native the proximal pulmonary artery directly into the aorta that fetal mammals?


Possible Answers:

The umbilical vein


The umbilical arteries


The ligamentum arteriosum


The foramen ovale


The ductus arteriosus


Correct answer:

The ductus arteriosus


Explanation:

In fetal mammals, oxygenated blood returns to the fetus via the umbilical veins. It then drains into the ideal side the the heart. There would certainly be no usage in sending out oxygenated blood into non-aerated lungs, so the is diverted through a channel, the ductus arteriosus, right into the aorta of the fetus.

At birth, this structure closes rapidly, enabling blood to pass the lungs of the newborn. A residual tape of connective tissue, the ligamentum arteriosum, clues the site of the original structure. The foramen ovale is a developmental aperture in between the atria, and it usually closes spontaneously together the heart develops.

Example inquiry #6 : understanding Circulatory ship


Which that the following statements is true around arteries and veins? 


Possible Answers:

Arteries bring blood far from the heart; veins bring blood towards the heart


Neither arteries nor veins lug blood towards the heart


Arteries bring blood toward the heart; veins lug blood away from the heart


Both arteries and veins lug blood towards the heart


Arteries and veins both carry blood towards the heart and also away indigenous the heart, depending upon their location


Correct answer:

Arteries bring blood far from the heart; veins lug blood towards the heart


Explanation:

The circulatory device of the human body is created of blood vessels. There room three main types of blood vessels: the arteries, the capillaries, and the veins.

Arteries always carry blood far from the heart. Normally the blood is oxygenated; the exceptions space the pulmonary arteries, which lug blood far from the love to the lungs to end up being oxygenated. Veins bring deoxygenated blood towards to love from tissue, v the exemption of the pulmonary veins, which carry oxygenated blood native the lungs to the heart. Capillaries enable for exchange between blood and also tissue.

Example inquiry #7 : expertise Circulatory vessels


Is the blood discovered in the jugular vein oxygen-rich or oxygen-poor, and why?


Possible Answers:

Oxygen-rich, since it carries blood indigenous the heart to the head and also neck.


Oxygen-poor, because it tote blood native the heart to the head and neck


Oxygen-rich, due to the fact that it dead blood from the head and also neck to the heart


Oxygen-poor, since it dead blood indigenous the head and also neck to the heart


Correct answer:

Oxygen-poor, since it carries blood indigenous the head and neck to the heart


Explanation:

Begin by remembering the arteries bring blood away from the heart. Veins lug blood native the body back to the heart. Note that the difference between the blood in arteries and veins does not lie in the oxygen-content. Rather, it lies in the direction of flow. Arteries always take blood far from the heart, conversely, veins always take blood back to the heart.

Example question #8 : knowledge Circulatory ship


Which that the following is true of veins and arteries?


Possible Answers:

Veins carry oxygen-rich blood earlier to the love via the pulmonary circuit


Arteries carry oxygen-rich blood earlier to the heart via the pulmonary circuit


Arteries carry oxygen-poor blood back to the heart via the pulmonary circuit


Veins lug oxygen-poor blood back to the heart via the pulmonary circuit


Correct answer:

Veins lug oxygen-rich blood back to the heart via the pulmonary circuit


Explanation:

Arteries carry blood away from the heart. In all however one case, arteries bring oxygen-rich blood. The exception is the pulmonary arteries. They lug oxygen-poor blood away from the heart, to the lungs, to pick up an ext oxygen. Veins bring blood ago to the heart. In all but one case, veins lug oxygen-poor blood. The exception is the pulmonary veins. They bring oxygen-rich blood native the lungs earlier to the heart.

Example question #9 : expertise Circulatory ship


Which the the following components of the circulatory system contain valves?


Possible Answers:

Capillaries


Veins


Arteries


All of these


Arterioles


Correct answer:

Veins


Explanation:

Veins room the only circulatory vessels that contain valves. These frameworks contain valves because much that the pumping pressure that originated in the heart has actually been reduced by the time blood get veins, which return deoxygenated blood to the heart. The reduction of pressure can reason the blood to pool or move an extremely slowly. Since veins rely largely on gravity, blood flow force (originating native the heart), and muscular contractions come squeeze blood v them, it provides sense because that them to have valves to keep blood from flowing backwards in in between muscular contractions.

Example inquiry #10 : expertise Circulatory vessels


Which of the adhering to carries oxygen-poor blood?


Possible Answers:

Aorta


Pulmonary arteries


Femoral artery


Pulmonary veins


Carotid artery


Correct answer:

Pulmonary arteries


Explanation:

The pulmonary arteries space the just arteries that contain oxygen-poor blood due to the fact that it dead blood into the lung to it is in oxygenated. By definition, arteries lug blood away from the heart and veins bring blood to the heart. However, the pulmonary vein is the only vein in the body the carries oxygen-rich blood (from the lungs ago to the heart to it is in pumped right into the rest of the body) and also the pulmonary artery is the only artery in the body that carries oxygen-poor blood (to the lung to be oxygenated before being sent out to the heart to be pumped right into the remainder of the body. The carotid artery is in the neck and also delivers oxygen-rich blood to head. The femoral artery is in the leg and also delivers oxygen-rich blood to the leg. The aorta is the key artery that delivers blood from the left ventricle that the love to the remainder of the body.
