the sympathetic nervous system redirects blood flow from organs to the muscles and then the blood vessels of the organs constricts to prevent blood returning.

Blood can flow freely through arteries because?
arteries are lined with smooth muscles
Does exercise produce energy in muscles?
yes it can and if you have a healthy diet and do lots of exercise you will have lots of oxygen to produce energy in muscles and when you exercise your heart beats and that means energy is going through your muscles hope this helped.
How do skeletal muscles help blood move in veins?
because of the blood muscles that push the heriastic pulley. the move the blood through the veins and arteries.
Why is exercise so importance?
Exercise improves the flexibility and strength of the muscles, and prevents excessive strain on the bones, tendons, and spine. Aerobic exercise improves the functioning of the cardiovascular system and the efficiency of the lungs. Exercise reduces the deposition of fat in the tissues, and can lower the level of fat in the blood (one factor in hardening of the arteries, atherosclerosis). Exercise also improves mood through the release of endorphins and hormones.
Where are your arms located?
Arms are attached to the shoulders by ligaments and muscles. Veins and arteries pass through from the neck and chest to each arm.
Is gas exchange in the arteries?
Yes. When ever the arteries take oxygen rich blood to your muscles, the muscles take the oxygen out to use it to create energy. The oxygen deficient blood is taking back to the heart through the veins, then taken back to the lungs to extract oxygen again
How do you get muscular in 3 minutes?
You can't. It takes time for muscles to build up through training and exercise.
What kind of blood vessels are helped by contraction of skeletal muscles?
Both veins and arteries. The contracting muscles on all sides of the vessels squeeze the blood along in the dire tion it is travelling, either away from (arteries) or back to (veins) the heart. This helps the heart so that it doesn't have to do all the hard work itself. In other words exercise is good for your heart. Medicine calls it the skeletal muscle pump.
What does aerobic exercise do to your muscles?
The cardiovascular system (heart, lungs, and other big muscle groups) are strengthened during aerobic exercise through continuous, rhythmic movement. When you exercise, your muscles require more blood that is rich in oxygen, which causes your heart to pump more quickly to keep up.
What type of exercise is running?
Running is cardiovascular exercise, because it increases the rate at which the heart pumps blood through your body to supply your muscles with oxygen during their contractions.
What is the coronary aretery?
The coronary arteries supply the heart itself with necessary oxygen. When these arteries are blocked, it can cause a myocardial infarction (heart attack). I think that the artery takes it through blood
Which of the following is not one of the ways to achieve overload or placement of greaterthannormal demands on muscles through exercise?
Increased rest periods
