Tracing the blood from the heart to the right hand, we find that blood leaves the heart and passes through the aorta, the right subclavian artery, the axillary and brachial arteries, and through either the radial or ulnar artery to arrive at the hand. Which artery is missing from this sequence? a. coronary, b. brachiocephalic, c. cephalic, d. right common carotid.

Hey, everyone. Let's take a look at this question together, which of the following represents the correct path of blood flow to reach the right lung. And here we have four different answer choices containing four different pathways. And we have to determine which answer choice contains the correct path of blood flow to reach the right lung. Well, we can see that all four answer choices include the right atrium and the right ventricle. So our correct pathway starts off in the right atrium, then goes into the right ventricle. And after the blood leaves the right ventricle, where does it go? And we know that after the blood leaves the right ventricle, it enters the pulmonary artery. And after it leaves the pulmonary artery, the blood enters the pulmonary veins and looking at our answer choices, which answer choice starts at the right atrium, then goes into the right ventricle, followed by that pulmonary artery and lastly the pulmonary veins. Well, we can see that answer choice A contains the correct path of blood flow to reach the right lung. So answer choice A is the correct answer and answer choice. BC and D are all incorrect since they do not contain the correct path of blood flow to reach the right lung. I hope you found this video to be helpful. Thank you and goodbye.
