What else can I help you with?
The heart is made up of cardiac muscles what happend when these muscles contract?
Yes, the heart is made of muscles, however, these muscles do not all contract at one time. They contract in synchrony and when they contract they squeeze the chamber they surround such are the atria or ventricle and blood is pushed out of the chamber.
What assists in the movement of blood throgh the veins other than the beat of the heart?
As skeletal muscles contract, blood is forced along the veins to the heart.
Where does the blood go after going to wall in heart?
it circulates through the body after the the muscles contract
Which muscles contract to push blood through the circulatory system?
The heart itself is a muscle that contracts to push blood through the circulatory system. In addition, the arteries also contract to help in pushing the blood along.
When the atria contract the blood is forced into the?
The blood is squeezed into the ventricles.
Do the veins rely on any other body part to work?
yes. they are situated close to muscles, when the muscles contract and relax this causes the blood to flow through them. blood is low pressure through veins therefore does not move fast, it relies on the muscle movement to move the blood through them. the valves prevent backflow of the blood.
What is blood forced through the body by?
By your heart pumping the blood through your veins.
What do a blood vessels bladder and an airway have in common?
They are all smooth muscles that contract involuntarily.
An electrical signal causes the atria to?
bubble up and popno one knowsthe signal causes the atria to contract.
Which of the following is not affected by muscles?
hair growth
How do muscles pump blood throughout the body?
Muscles pump blood throughout the body by contracting and relaxing. When muscles contract, they squeeze the blood vessels, pushing blood forward. This helps to circulate blood to all parts of the body, delivering oxygen and nutrients while removing waste products.
What are three things muscles can do?
Allows for organism movement (skeletal muscles) or organ movement (cardiac muscles, smooth muscles of the gastrointestinal tract) Generates heat (in endotherms) Allows for blood to return to the heart after it has flowed to the extremities (by squeezing the veins when they contract)
