I would be happy to help with that! When arteries harden and become rigid, it is called arteriosclerosis. Arteriosclerosis is a condition where the arteries become thickened and less flexible due to a buildup of plaque on the arterial walls. This can restrict blood flow and lead to various cardiovascular problems.
Here's a breakdown of the answer choices:
- Oa. Diastole: Diastole refers to the phase of the cardiac cycle when the heart relaxes and fills with blood. It is not the term used to describe hardened and rigid arteries.
- b. Systolic: Systolic pertains to the phase of the cardiac cycle when the heart contracts and pumps blood out into the arteries. It is not the term used to describe hardened and rigid arteries.
- c. Nonelastic: This term describes a lack of elasticity or flexibility, which is characteristic of hardened and rigid arteries.
- Od. Arteriosclerosis: This is the correct term for the condition where arteries harden and become rigid due to plaque buildup, leading to decreased blood flow and potential health complications.
