Valves in veins prevent the backflow of blood, ensuring that it moves toward the heart despite the low pressure in the venous system. Skeletal muscles assist in this process through a mechanism known as the "muscle pump," where muscle contractions compress nearby veins, pushing blood upward. When muscles relax, the valves close to maintain unidirectional flow, aiding in efficient circulation. Together, these structures help return deoxygenated blood to the heart, especially from the lower extremities.

What helps to coordinate and smooth skeletal muscles?
cerebellum
What head muscle helps you bite a carrot stick?
The same muscles that allow you to smile. Your jaw muscles of course!
What helps organisms keep there shape?
Skeletal muscles and Bone.
What are the functions of the heart, skeletal muscles, and diaphragm in the muscular system?
The heart pumps blood to deliver oxygen and nutrients throughout the body. Skeletal muscles allow for movement and support the body's structure. The diaphragm helps with breathing by contracting and relaxing to control the flow of air in and out of the lungs.
What kind of muscles is a Zygomaticus major muscle?
The zygomaticus is a skeletal muscle, and as such is a 'striated' muscle. It is also a parallel muscle. It functions in chewing, and is therefor one of the 'Masticating' muscles.
What body system supports muscles and organs and helps an animal move from one place to another?
skeletal system
What tissue type functions in contraction?
Muscle tissue functions in contraction. There are three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscles are involved in voluntary movements, smooth muscles are found in organs and blood vessels and help with involuntary movements, and cardiac muscle is found in the heart and helps with pumping blood.
How do skeletal muscles generally work?
It helps you do anything you really do any thing if you didn't have muscles you couldn't play or do anything.
What do the skeletal muscles allow us to do?
It helps move you. Your bones make up your structure. These muscles allow your body to move.
What do the body's skeletal muscles do?
it helps us move and gives the proper shape of the body
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.
Identify effects to skeletal muscles when excercising?
It makes them larger and stronger! Hope it helps! xx
