Oxygenated blood flows from the lungs to the left atrium contractions (heart muscle) cause the blood to leave the atrium and enter the left ventricle. Further contraction causes the blood to leave the atrium and enter the aorta.

Why are deposits inside arteries a problem for the human circulatory system?

Because they restrict the amount of blood passing through the arteries. If there are fatty deposits around the edges of the artery or vein, then there is less room for the blood to get through. This would mean that less blood would get through with each heart beat, and could cause more serious injuries - for example, a heart attack.

What is the pathway of the blood in renal circulation?

Blood enters the kidneys via the renal arteries, which branch off the abdominal aorta. Inside the kidney, the renal arteries further divide into smaller arterioles, eventually leading to the glomerulus where filtration occurs. After passing through the glomerulus, blood flows through the renal veins, ultimately exiting the kidneys through the renal veins.
