In arteriosclerosis, overproduction of abnormal collagen and decreased quantities of elastin lead to Decreased coronary artery perfusion.
Arteriosclerosis is a condition in which the arteries, which transport oxygen and nutrients from the heart to the rest of the body, thicken and stiffen, often limiting blood flow to the organs and tissues. Flexible and elastic arteries indicate good health. However, the artery walls can stiffen over time, a phenomenon known as arterial hardening.
The accumulation of lipids, cholesterol, and other chemicals in and on the artery walls is known as atherosclerosis. The accumulation is known as plaque. Atherosclerosis can constrict the arteries and obstruct blood flow. The plaque may rupture and cause a blood clot.
Symptoms of arteriosclerosis:
- chest pressure or discomfort (angina)
- sudden numbness or weakness in the arms or legs.
- speech slurs or speaking difficulties.
- vision briefly lost in one eye.
- weakened facial muscles
- ache while walking.
- elevated blood pressure
- renal failure

Answer:
Steps to cellular respiration:
1) In the first step of respiration, glycolysis occurs in which glucose molecule is converted into pyruvate molecule.
2) Krebs cycle is also called citric acidity cycle. In this cycle, hydrogen and electron are produced from the oxidation of pyruvate molecule and provides to electron transport chain.
3) Electrons carried by NADH + H and FADH2 are converted into oxygen through a series of electron carriers, and production of ATP occurs.

Producing as many offsprings as possible so the chance of them living is higher.
Explanation:
They appear larger than they really are.
