What is the main function of your respiratory system?

The main function of your respiratory system is to pull in oxygen for your body’s cells and get rid of carbon dioxide, a waste product. You do this by breathing in and out and through gas exchange between the small air sacs of your lungs (alveoli) and the blood vessels running nearby.…[Read more]

*Do veins have valves?*

Veins, unlike arteries, have valves that ensure blood only travels in one way. Arteries don’t need valves since the heart’s pressure is so high that blood can only flow in one way. Valves also assist blood is returning to the heart against gravity.

Most veins have valves that open and close. The valves control blood flow…[Read more]

*What are the two types of veins?*

1. pulmonary veins

2. systemic veins

Pulmonary veins. The pulmonary circuit carries deoxygenated blood from your heart to your lungs. Once your lungs oxygenate the blood, the pulmonary circuit brings it back to your heart. There are four pulmonary veins. They’re unique because they carry oxygenated blood.…[Read more]

*Are veins bigger than arteries?*
No. Veins are not bigger than arteries. The walls of veins have the same three layers as the arteries. Although all the layers are present, there is less smooth muscle and connective tissue. This makes the walls of veins thinner than those of arteries, which is related to the fact that blood in the veins has l…[Read more]

*Why are veins thinner than arteries?*

Veins are thinner due to the low pressure. Your veins are thinner and less stretchy. This structure helps veins move higher amounts of blood over a longer time than arteries.

*Why do arteries have thick walls?*

Arteries have thick muscular walls because blood pressure in them is high and because they must adjust their diameter to maintain blood pressure and to control blood…[Read more]

*How are the arteries and veins similar?*

Both arteries and veins play key roles in the circulatory system, moving blood to and from tissues. Arteries and veins (also called blood vessels) are tubes of muscle that your blood flows through. Arteries and veins form a part of the circulatory system of the body. Both these vessels maintain the flow…[Read more]

*What are the 3 main differences of arteries and veins?*
Both arteries and veins are crucial part in circulating blood, however, they have differences. There are three main differences.

1. Arteries carry blood away from the heart, and veins carry blood towards the heart.
2. With the exception of pulmonary blood vessels, arteries carry o…[Read more]

What are the three main differences between arteries and 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…[Read more]

Quality controls are used to monitor the performance of testing procedures and are typically used to check the accuracy of test results.

Calibrators consist of materials or devices that have known values, which are used to compare other materials or devices to. This comparison is done to ensure the accuracy of test results. Calibrators are…[Read more]
