Explanation:
Answer: Electricity can travel through AED
Explanation: AED is Automated external defibrillator.
AED is used in patients that have cardiac arrest,it is used to re-establish or return back the heart rhythm of a patients whose heart stopped beating due to an illness or accident,the AED does so but analysing the heart rhythm of the victim and re-establishing an adequate heart rythym when shocked.
Using an AED is delicate,though it can be used in every weather condition, but the victim should be moved to a dry area because water is a good conductor of electricity,this is for the safety of both the victim of cardiac arrest and the Healthcare provider,when the pads are placed appropriately in the patient/victim,the AED analyzes the rhythm of the patient, if it is a shockable rhythm,the health care provider slightly moves away from the patient and press the shock button to deliver the shock.moving away of the healthcare provider is to avoid electrocution.
Answer:
B. Ashchronous recruitment
Explanation:
Asynchronous muscles are muscles that Don't have one-to-one relationship between electrical stimulation and mechanical contraction. Such muscles can be found in About 75% of flying insects and they have convergently evolved 7-10 times.
The synchronous muscles which is their counterparts contracts once per neural signal, but mechanical oscillations trigger force production in asynchronous muscles.
Hence the rate of mechanical contraction is an order of magnitude greater than electrical signals.
Although they achieve greater force output and higher efficiency at high frequencies, they have limited applications because of their dependence on mechanical strength.
The nervous system recruits the Ashchronous muscle to avoid muscle fatigue during submaximal contraction.
