Need help with page 2 of questions here. 2) Answer the following questions about an experimental preparation where you have cut all nerves leading to a frog'sheart and taken the heart out of its body and placed it into a physiological saline solution.a. Why can the frog's heart still beat when it is isolated from the body?b. Would you expect it to beat faster, slower, or at the same pace as the frog's normal resting heart rate? explain why.C. How could you experimentally decrease the heart rate in this isolated condition?d. You have placed an electrode into a cardiac ventricular muscle cell. Draw the ventricular myocyte action potential youwould expect to see under completely denervated conditions and after your experimental manipulation.2

Frog's heart Contains three chambers and no division between oxygenated and deoxygenated blood. It is divided into two main chambers: Sinus Venosus, which receives blood, and Conus Arteriosus, which departs blood."Answer 1. To excite itself, the frog's heart is not dependent on the neurological system. As a result, the frog's heart is autoexcitable. As a result, it continues to beat even after being removed from the body for a period of time. 2 . A frog's heart beats at a regular pace of 40 to 50 beats per minute. It will be noted that increasing the temperature causes the frog's heartbeat to rise. It will be above 63 beats per minute at average temperature, which is roughly 37 degrees Celsius. We should not use solutions that are below 5 degrees Celsius or above 45 degrees Celsius since they are hazardous to the animal. At low temperatures, the frog's heart stops pumping. 3. The heart is then perfused with Ringer solution via the sinus venosus. The perfusion rate is set to 30-40 drips per minute. A curved needle is inserted into the apex and connected to a heart lever to record contractions on smoked paper placed over a kymograph's drum. The heart lever of the starling is used. 4.
