Which of the following describes the flow of blood between the heart and the lungs?

A. heart-capillaries-veins-arteries-heart

B. heart-arteries-veins-capillaries-heart

C. heart-arteries-capillaries-veins-heart

D. heart-veins-capillaries-arteries-heart

Answer: C. heart-arteries-capillaries-veins-heart

Pulmonary circulation entails how blood is moved between the heart and the lungs. Deoxygenated blood is transported to the lungs so as to get them to absorb oxygen and release carbon dioxide. This oxygenated blood then moves back to the heart. The heart, veins, arteries, and capillaries are the main constituents of the circulatory system.

This deoxygenated blood leaves the right ventricle of the heart and then goes through the pulmonary trunk into the pulmonary artery. The arteries then transport the blood to the capillary beds of the lungs. With this, carbon dioxide is released and oxygen is absorbed. This blood, now oxygenated, then flows from the capillary beds into the pulmonary veins and then back to the heart.

Total time spent: 4 hours 15 minutes (it is equivalent to 255 minutes). Let the flight time from Paris to Glasgow be X. Then the flight time from Glasgow to Paris will be (X+10). We have an equation with one unknown variable: X + 45 + (X+10) = 255 ⇒ X = 100 So the […]

The first method uses a pool of chemicals that turns solid when light, typically a UV laser, is shone on to it. The […]
