What effect was seen after adding K+ to the heart?

The effect of increasing the potassium ions caused the heart rate to decrease from 61 to 28 and with the increase of potassium, this lowers the resting membrane potential.

What happens to the heart rate if the vagus nerve is cut?

Mechanical pertubation of the vagus nerve during neck dissection may stimulate actions that cause changes in the cardiac rhythm and rate. Also traction of the vagus nerve has often resulted in bradycardia (slow heart rate) and decreased blood pressure [15].

What effect does extreme vagus nerve stimulation have on the heart?

It is also possible to stimulate the vagus nerve directly to improve parasympathetic tone and reflexes. It has been shown that vagal nerve stimulation (VNS) leads to improved left ventricular haemodynamics, increased heart rate variability, better vagal reflexes, and greater nitric oxide expression.

Which Ion had the greatest effect on the frog heart?

Why does frog heart keep beating?

They are releasing heat, which keeps the electrochemical reactions in muscles going so the muscles of heart keep contracting after the removal of heart from the body.

Why does the frog heart continue to beat after the frog is euthanized?

Why is my blood almost black?

It owes its color to hemoglobin, to which oxygen binds. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).
