Question

Describe the path a red blood cell would take traveling through the body. Start your RBC in the right atrium and show its path until it returns to the right atrium. Should be at least 7 steps or more

Answer 1

ANS)

STEP 1 - Formation of RBC/Red Blood Cell

The RBC is made inside the bones.In the bone marrow the RBC is formed through various stages begining as hemocytoblast,after that it is changed to a erythroblast after three to five days of formation.

After completing the filling of hemoglobin,that is changed as a reticulocyte and after that it is changed to completely matured RBC

STEP 2 - Starting of RBC's journey

After the formation of RBC,it begin its journey to heart through capillaries.Blood cell is presently deoxygenated.

STEP 3 - Getting into the heart

Now the deoxygenated RBC will move to the vena cava present in the heart.After this,the RBC is just pushed to the right atrium of the heart.

when the RBC reached in the right atrium,the right atrium will perform contraction and this pushes the RBC to the right ventricle via tricuspid valve.

Now the right ventricle will contract and that contraction will push the RBC out of the heart via semi lunar valve.

STEP 4 - Getting into the lungs and the oxygenation.

The RBC after coming out of the heart,it will just move to the lungs through the way of pulmonary artery.In the lungs the RBC takes up the oxygen and converting the deoxygenated RBCto oxygenated RBC.After that the RBCmakes it route back to heart to the left atrium through the pulmonary vein.

STEP 5 - Coming back to the heart

The RBC after getting into the left atrium,it then contracts and push the RBC via bicuspid valve,the RBC the get into the left ventricle.

After that the left ventricle starts contraction and it push the RBC via semi lunar and out of heart to the aorta.

STEP 6 - Journey through the body.

Moving through the aorta and going to kidney trunk and lower limbs,spreading the oxygenated blood throughout the body.And its life span is 120 days.

STEP 7 - Returning to right atrium

Now from all the organs and other lower limbs,it carry the deoxygenated blood back to right atrium through vena cava and this process continues as a cycle.
