Because the AV node takes on the role of a very important delay in the cardiac conduction system. Without this delay, the atria and ventricles would contract at the same time.
<h3>Cardiac conduction system</h3>
The conduction system of the heart sends electrical signals, usually generated by the sinus nodes, causing the heart muscle to contract. Pacemaker signals originating from the sinus node travel through the right atrium to the atrioventricular (AV) along the bundle of His and through branches of the bundle, causing myocardial contraction. This signal first stimulates contraction of the right and left atria then flows to the right and left ventricles. That electric current then allows blood to be pumped throughout the body.

Answer: a. autoclaving
Explanation:
Autoclaving is the technique of sterilization. The autoclaves are set at a particular time and temperatures. The two parameters are necessary for the proper functioning of the autoclave. The standard temperature for the functioning of the autoclave is the 121°C for a time period of 15 minutes.
The time extends according to the increase in the quantity of the autoclaving material, particularly for large volumes of liquid and for more dense materials. It is a benificial and useful technique for sterilizing surgical dressings, glasswares, microbial media, biohazardous materials,and others.
