Blood brings oxygen and ATP, which react with one another (oxidation), to the muscle cells. The result of this oxidation process (aerobic) is energy and heat. (Most of the body's heat originates from muscle activity.)
Skeletal muscles will not contract unless stimulated by neurons.

Why do you need the Tesla coil?
Tesla used it to study how to supply electricity wireless. In his days, it was not allowed but some companies are manufacturing components that could supply little electricity.
Where do muscles get the energy they need to do work?
The energy is produced through an aerobic process called oxidative phosphorylation. About 60% of energy comes from fatty acids and triglycerides and 35% from carbohydrates. The remaining 5% is from amino acids and ketone bodies. The oxidation is supported by myoglobins that store oxygen in the muscle.
Why do you need energy?
So that we will have a constant supply of energy on earth for future generations. If we use all our nonrenewable resources before we can make renewable energy constantly usable, then we might not have energy.
Why a lack of gravity might cause muscles to weaken?
Because if you don't use it, then you lose it.
How much protein does 64 kg male need?
115 grams ( 64Kg * 1.8 grams of protein ) If you want to gain muscles.
Why do cardiac muscles have a better capillary network than skeletal muscles?
Cardiac muscle have a greater need for oxygen than skeletal muscles because they use up more energy in a shorter amount of time so they require regular refills of oxygen.
What are muscles skeletal cardiac and smooth?
smooth muscle is used in a train of thought (brain is need in the act) cardiac muscle can be found in the heart skeletal muscle moves your bones
What is steady exercise in which the heart can supply all the oxygen the muscles need?
Aerobic exercise
Why must skeletal work in pairs to move a bone?
Skeletal muscles work in pairs to move a bone so that the muscles can function properly. Muscles can only pull, therefore bones need two muscles to make it move. To put a finger up one muscle might pull, the other will put to put back down. With two, the movement will be smooth, otherwise it will be "jerky" and uncontrolled.
Why ligaments a part of the skeletal system?
If we didn't have a skeletal system we would be a blob on the ground. If we didn't have bones well basically the same thing but also we wouldn't be able to produce blood or marrow.<----- (important) We also need tendons and ligaments so our muscles stay attached to our bones (another reason why we need bones) and allow smoother movement.
What would happen if part of your skeletal system was removed?
Since muscles need bones to work on, we would not be able to move or do other functions.
Why is it important that muscular system be nourished by the blood on a priority basis?
It is important that muscular system be nourished by the blood on a priority basis. This is because the muscles are constantly using energy and need to be nourished and have the energy replaced.
Is bamboo vascular or non-vascular?
they're nonvacular
Does skeletal muscle need stimulation to contract?
Yes! Although we have total control over these muscles, they still need stimulation to contract. The difference with muscles that we don't control is that we decide if we want to make this stimulation.
Why does the muscular system need the circulatory system?
the cardiovascular system needs the skeletal system because the skeletal system protects the organs of the cardiovascular system with the ribs and other bone parts. Also bone produces erythrocytes (red blood cells) and leukocytes (white blood cells) which of course are essential for the cardiovascular system
What does the skeletal system do to meet the cells need?
The skeletal system meet the cells need by .....
