Arteries carry oxygen to the muscles of the body.
The cardiovascular system sends oxygen to the muscles.
nutrition and oxygen
you use oxygen in your muscles to do work and anaerobic respiration uses oxygen.
You breathe in and the oxygen goes into your lungs. Your blood picks up the oxygen and carries it to your muscles, and then goes into the cells in said muscles.
Muscles contain an oxygen storage pigment called myoglobin. Myoglobin helps muscles store and transport oxygen for energy production during exercise.
The cardiovascular system, specifically the red blood cells, is what transports oxygen to the muscles.
Yes, cardiac muscles cells have a very high oxygen demand, since they are constantly in motion. This is why any shortage of oxygen causes angina, or if the oxygen deprivation is long enough, it causes death of the muscle cells - what is commonly called a heart attack.
because your blood carries oxygen to you muscles. without much oxygen blood won't be able to take lots to your muscles, and with little oxygen your muscles won't work as well and therefore you won't run as quickly :)

The muscles do not have enough oxygen for aerobic respiration.
