Arteriosclerosis, Arteriolosclerosis, and Atherosclerosis

Learn the difference between Arteriosclerosis, Arteriolosclerosis, and Atherosclerosis! Rishi is a pediatric infectious disease physician and works at Khan Academy.

Atherosclerosis - Part 1

See how Atherosclerosis (Fat in the blood vessel wall) hardens the arterial wall and makes it harder for blood to flow through. Rishi is a pediatric infectious disease physician and works at Khan Academy.

Atherosclerosis - Part 2

See how Atherosclerosis (Fat in the blood vessel wall) hardens the arterial wall and makes it harder for blood to flow through. Rishi is a pediatric infectious disease physician and works at Khan Academy.

Arteriolosclerosis - Part 1

See how hyaline arteriolosclerosis (Protein in the arterial wall) causes hardening of the blood vessels. Rishi is a pediatric infectious disease physician and works at Khan Academy.

Arteriolosclerosis - Part 2

See how hyperplastic arteriolosclerosis (Protein in the arterial wall) makes it difficult for blood to go through blood vessels. Rishi is a pediatric infectious disease physician and works at Khan Academy.
