Final answer:
When cells don't get oxygen, it can lead to hypoxia and cell death. Arteriosclerosis can reduce blood flow and oxygen delivery to cells. Lack of oxygen to cardiac muscle cells can cause severe impairment of heart function.
Step-by-step explanation:
When cells don't get oxygen, it can lead to a condition called hypoxia, which is a decreased supply of oxygen to the tissues.
Arteriosclerosis, a condition characterized by the narrowing and hardening of arteries, can contribute to reduced blood flow and insufficient oxygen delivery to cells.
If cardiac muscle cells in the heart don't receive enough oxygen, it can lead to cell death and severe impairment of heart function.
