What is the first part of the cardiac cycle called?
The first part of the cardiac cycle is called diastole, which is when the heart relaxes and fills with blood. This is followed by systole, when the heart contracts to pump blood out to the body.
How does the structure of cardiac myocytes and intercalated discs follow the function of cardiac muscle tissue and the heart?
The structure of the heart is very complex. Cardiac myocytes and intercalated discs follow the function of cardiac muscle tissue and the heart make up part of this very complex system
Is the p wave part of the cardiac cycle?
Yes - On an ECG the P wave is the first wave of the cardiac cycle. It represents the Sinoatrial node which is the natural pacemaker of the heart firing and causing the atria to contract in order to fill the ventricles.
What is the relaxing phase of the cardiac cycle?
The relaxing phase of the cardiac cycle is called diastole. During diastole, the heart chambers (atria and ventricles) relax, allowing them to fill with blood. This is followed by the contracting phase called systole.
What system that is most closely associated to includes both smooth and cardiac muscle?
These two come under the section called tissues. They are part of two different systems: cardiac and digestive.
What part of the heart fails to work during cardiac shock?
Cardiac muscle or heart muscle is the part of the heart that fails to work during cardiac shock.
Is an ulcer a cardiac muscle?
No, an ulcer is a abcess not a cardiac muscle which is by the way related or part of the heart.
What is the protein and enzyme complex that is important in controlling the cell cycle?
The protein and enzyme complex that is important in controlling the cell cycle is called cyclin-dependent kinase (CDK). CDKs are activated by binding to specific proteins called cyclins, forming a complex that regulates the progression of the cell cycle by phosphorylating key target proteins. This complex is crucial for ensuring proper cell division and maintaining genomic stability.
Is a cardiac muscle cell a plant or animal cell?
Animal cell because cardiac is part of the heart
In which part of the body would you find the cardiac muscle?
cardiac muscles are located in the heart only
What happens the cardiac cycle when you have a heart attack?
During a heart attack, blood flow to a part of the heart is blocked, leading to ischemia and potential damage to the heart muscle. This disruption affects the cardiac cycle by impairing the heart's ability to contract effectively, which can reduce stroke volume and overall cardiac output. As a result, the heart may struggle to maintain adequate blood circulation, leading to symptoms like chest pain, shortness of breath, and potential arrhythmias. If not treated promptly, this can lead to severe complications and even death.
What do you call the muscle of the heart?
I believe you are talking about the Cardiac Mucle. Cardiac muscle is part of what the human heart is made up of.
