What else can I help you with?
What is the function of the auricle in the heart and how does it contribute to the overall cardiac function?
The auricle in the heart acts as a reservoir that helps collect blood and allows for efficient filling of the ventricles. This contributes to the overall cardiac function by ensuring a steady flow of blood into the heart chambers, which helps maintain proper circulation and cardiac output.
How do intercalated discs contribute to the synchronized contraction of cardiac muscle cells?
Intercalated discs in cardiac muscle cells help synchronize their contractions by allowing electrical signals to pass quickly between cells. This communication ensures that the heart muscle contracts in a coordinated manner, leading to efficient pumping of blood.
What is cardiac filling called?
Cardiac filling is also referred to as diastole, which is the period of the cardiac cycle when the heart muscle relaxes and fills with blood.
Which tissue has intercalated discs?
Cardiac muscle tissue has intercalated discs, which are specialized structures that help with communication and coordination of muscle contractions in the heart.
Do you defibrillate asystole during cardiac arrest"?
No, defibrillation is not effective for treating asystole during cardiac arrest.
How is heart muscle different from striated muscle?
Cardiac muscle is a type of involuntary striated muscle found in the walls of the heart, specifically the myocardium. Cardiac muscle cells are known as cardiac myocytes (or cardiomyocytes). Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. The cells that comprise cardiac muscle are sometimes seen as intermediate between these two other types in terms of appearance, structure, metabolism, excitation-coupling and mechanism of contraction. Cardiac muscle shares similarities with skeletal muscle with regard to its striated appearance and contraction, with both differing significantly from smooth muscle cells.Source: http:/en.wikipedia.org/wiki/Cardiac_muscle

What happens if the cardiac sphincter relaxes?
If the cardiac sphincter relaxes, it allows stomach contents to reflux back into the esophagus, causing acid reflux or heartburn. This can lead to symptoms like chest pain, regurgitation, and a sour taste in the mouth. Chronic relaxation of the cardiac sphincter can contribute to gastroesophageal reflux disease (GERD).
Cardio-respiratory training particularly running if begun without proper prepararation can contribute to?
Cardiac arrest . . . in other words, heart attack.
What is cardiac muscle?
Cardiac muscle is a type of highly oxidative (using molecular oxygen to generate energy) involuntary striated muscle found in the walls of the heart, specifically the myocardium. Cardiac muscle cells are known as cardiac myocytes. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. The cells that comprise cardiac muscle are sometimes seen as intermediate between these two other types in terms of appearance, structure, metabolism, excitation-coupling and mechanism of contraction. Cardiac muscle shares similarities with skeletal muscle with regard to its striated appearance and contraction, with both differing significantly from smooth muscle cells. Coordinated contraction of cardiac muscle cells in the heart propel blood from the atria and ventricles to the blood vessels of the circulatory system. Cardiac muscle cells, like all tissues in the body, rely on an ample blood supply to deliver oxygen and nutrients and to remove waste products such as carbon dioxide. The coronary arteries fulfill this function
Which type of muscle is the heart made of?
cardiac
Muscle tissue that has intercalated disks?
cardiac muscle cells are joined by intercalated disks.
What is cardiac necrosis?
Cardiac Necrosis is the death of cardiac tissue.
What is cardiac rest?
its not cardiac rest, its cardiac ARREST. which is a heart attack.
Infants found in cardiac arrest are usually in arrest as a result of?
Infants in cardiac arrest are often in that state due to respiratory failure, which can lead to hypoxia and subsequent cardiac arrest. Common underlying causes include congenital heart defects, severe infections, or conditions like sudden infant death syndrome (SIDS). Additionally, metabolic disturbances or trauma can also contribute to cardiac arrest in this age group. Prompt recognition and intervention are critical for improving outcomes.
What is resting cardiac output?
its not cardiac rest, its cardiac ARREST. which is a heart attack.
What characteristics of cardiac muscle contracts the heart as a unit?
Cardiac muscle cells, or cardiomyocytes, are interconnected by specialized structures called intercalated discs, which contain gap junctions that allow electrical signals to pass rapidly between cells. This electrical coupling enables the heart to contract as a synchronized unit, known as functional syncytium. Additionally, cardiac muscle is striated and has intrinsic rhythmicity due to pacemaker cells, which initiate contractions and help maintain a consistent heartbeat. These characteristics ensure efficient and coordinated heart contractions to pump blood effectively.
