Ok I am so confused with this bio question?

Question

Can someone answer this question?

Trace the circulatory flow from a drop of a blood to the heart.

Answer 1

Do they mean a drop of blood from where blood cells are produced? Bone marrow produces red blood cells which , make up the majority of blood. Blood also consists of white blood cells (immune system), iron (diet), platelets, hormones, minerals and nutrients. Once they are produced and combined they enter the blood stream and move through veins to the heart where they are pumped to the lungs to be oxygenated. they then return to the heart and are pumped via arteries to the rest of the body.

Answer 2

Ok, so a drop of unoxygenated blood originates from the right atrium. From this point, the atrium pumps blood into the right ventricle which pumps the blood upwards into the pulmonary (lung) circulatory system which travels to alveoli in the lungs to become oxygenated. From the lungs, blood travels back to the heart into the left atrium which pumps blood into the left ventricle. The left ventricle then pumps the blood upwards through the atrium and to the systemic circulatory system. Blood travels to your organs, becomes deoxygenated, and then back to your right atrium.

I hope this helps!

Answer 3

that is a confusing question for sure. it is hard to trace the path of a drop of blood without knowing where your starting point is supposed to be.

Answer 4

You don't say where the blood is supposed to start, but here are the basics:

right atrium
right ventricle
pulmonary arteries
lungs
pulmonary veins
left atrium
left ventricle
aorta
major arteries
smaller arteries
arterioles
capillaries
venules
veins
superior and inferior vena cavae
....
left atrium .....

Answer 5

how about tracing it from the ventricle to the pulmonary artery (where it brings back oxygenated blood) to the heart and out to the body...
