Heart cells have a limited capacity to divide and regenerate, with a low turnover rate compared to other cell types in the body. The decay rate of heart cells can vary depending on factors such as age, overall health, and underlying medical conditions. In general, heart cells have a long lifespan and can last for many years without being replaced.

Vagus nerveWhat is the effect of vagus nerve stimulation on the heartbeat?
Vagus nerve stimulation can decrease heart rate by inhibiting the electrical activity of the heart's pacemaker cells, which are responsible for setting the heart rate. This can be therapeutic in conditions where a slower heart rate is beneficial, such as in certain cases of epilepsy or heart failure.
How the radioactive decay rate be changed?
The rate cannot be changed.
As the temperature of a radioactive sample increases the rate of the nuclear decay?
The rate of nuclear decay increases as the temperature of a radioactive sample increases. This is due to the increased kinetic energy of the nuclei at higher temperatures, which facilitates interactions that lead to nuclear decay.
Is decay rate a chemical or physical property?
Decay rate is a chemical property, as it relates to the rate at which a substance undergoes chemical reactions or transformations over time.
How can you show you are releasing energy during respiration?
You can show you are releasing energy during respiration by measuring your heart rate and breathing rate. As your cells release energy through respiration, your heart rate and breathing rate will increase to deliver oxygen to your cells more efficiently. This is known as aerobic respiration, which produces ATP (energy) for your body's functions.
What are the group of cells that adjusts the heart rate?
Pacemaker
Effect of calcium ions on the heart rate?
Calcium has no effect on heart rate. It does, however, have an effect on how hard the heart squeezes (inotropic effect). Heart rate is effected by the slow sodium channels in the pacemaker cells in the right atrium (and other pacemaker cells if the SA node is malfunctioning).
After how long corpse will start to decay and why corpse will decay?
The process of decay in a corpse can begin shortly after death, as soon as a few minutes to a few hours, depending on environmental factors. Decay occurs due to the breakdown of cells and tissues by microorganisms like bacteria and fungi, which release enzymes that break down proteins and tissues, leading to the characteristic odors associated with decay. Factors such as temperature, humidity, and presence of insects can also influence the rate of decay.
What cells set the heart rate?
answer it ya self feck head
Is a pacemaker a group of cells located in the left atrium?
A pacemaker is a device inserted into the heart to regulate the heart beats or heart rate
What conducting cells set heart rate?
Sinoatrial Node (SA node)
What are prokaryotic cells that cause disease and decay?
Bacteria are prokaryotic cells that cause disease and decay.
How does heart rate counters work?
These work by picking up electrical signals that are released when the heart muscle cells contract.
What is the sa node?
The SA node is the "pacemaker" of the heart. Cells in the SA node are called "pacemaker" cells and they direct the contraction rate of the entire heart by generating action potentials.
Vagus nerveWhat is the effect of vagus nerve stimulation on the heartbeat?
Vagus nerve stimulation can decrease heart rate by inhibiting the electrical activity of the heart's pacemaker cells, which are responsible for setting the heart rate. This can be therapeutic in conditions where a slower heart rate is beneficial, such as in certain cases of epilepsy or heart failure.
How the radioactive decay rate be changed?
The rate cannot be changed.
What makes your heart rate go down?
your heart rate goes down when there is more oxygen fueling your blood and oxygenating the organs and cells within your body
