What is water cycle evaperation?
Everyday, the heat of the sun cause water on the Earth's surface to change into a gas. This process is known as evaperation or evaporation.
What role does the unique structure of cardiac muscle play in its function?
Cardiac muscle has what is known as intercalated disks. These connect heart muscle cells to each other, which allows an impulse (contraction) to move through the heart synchronously and therefore beat as it should.
What are the dark reactions of photosynethesis also known as?
It is known as the Calvin cycle or light independent cycle
What do heart muscle cells look like?
The cells of heart muscle are striated (like stripes on a tie) as is skeletal muscle. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart. They can contract but also carry an action potential (i.e. conduct electricity), like the neurons that constitute nerves. Some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. That is they beat on their own and in union with each other.
What is the heart muscle cells special feature?
The muscle has unique features that are only in the heart.These muscles are involuntary striated muscle which are only found in the wall of the heart. This is specialised muscle that can contract, Cardiac muscle, like other muscles, can contract, but it can also carry an action potential (i.e. conduct electricity), like the neurons that constitute nerves.Furthermore, some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity.Read more: Why_is_the_cardiac_muscle_unusual
One complete heart beat is known as?
Cardiac Cycle
What is the relaxing phase of the cardiac cycle?
The resting phace of the cardiac cycle is known as the refractory period
What is the specialized region at the cardiac muscle that makes sure the heart never skips a beat?
cardiac cycle The sino-atrial node, otherwise known as the pacemaker.
What is the main section of the heart that initiats the cardiac cycle also known as the pacemaker?
Sinoatrial node, or SA node.
What is cardiac death?
"Cardiac arrest" better known as a heart attack.
What is your heartbeat known as?
Heartbeat is also known as pulse or cardiac cycle.
What does the cardiac muscle provide?
The cardiac muscle is also known as the heart. The heart function is to pump blood around the body.
What is cardiac arrest commonly known as?
A heart attack.
What part of your body has cardiac muscles?
The heart; also known as the only organ that uses cardiac muscle in the whole body.
What happens if cardiac muscles do not contract?
You would get a heart attack otherwise known as a cardiac arrest.
What type of muscle pumps blood?
all your muscles from your heartORCardiac muscle
What is the role of a cardiac enzyme?
Cardiac enzymes (also known as cardiac markers) are a substance released into the blood when one has heart problems, they help doctors diagnose if someone has had a heart attack.
