complete the flow of deoxygenated blood other parts of the body (a)_____(b)_____tricuspid valve (c)______(d)_______capillary bed

NemiM [27]

Answer:

The correct flow is - the body (a) Venules/vein/vena cava (b) Right atrium tricuspid valve (c) Right ventricle (d) Pulmonary artery, capillary bed of the lungs(alveoli)

Explanation:

Deoxygenated blood is moved from the tissues to the venules, veins or vena cava to the right atrium chamber and move through the tricuspid valve present in between both right chambers right atrium and right ventricle.

From the right ventricle, the deoxygenated blood is pumped into the pulmonary artery that takes the blood to the lungs more specifically to the capillary bed of lungs.

Thus, the flow is - the body (a) Venules/vein/vena cava (b) Right atrium tricuspid valve (c) Right ventricle (d) Pulmonary artery, capillary bed of the lungs(alveoli)
