Explanation:
The Human Excretory System is crucial in removing or discharging wastes from the body. Wastes may come in the form of urine, earwax, excrement, sweat, carbon dioxide, etc.
The "skin" is part of the Excretory System that is responsible for removing<em> salts</em> from its surface in a process called<u> sweating</u>. On the other hand, the "lung" is responsible for excreting <em>"carbon dioxide</em>." Having high levels of this element in the blood will lead to <u>failure of the respiratory system</u>.

Answer: The actions that results in the best chance of survival is (Start CPR, and use an AED if one is available).
Explanation:
First aid is a life saving procedures which are carried out in emergency situations by either a trained personnel or any available individual following a guideline. These life threatening emergency situations include:
--> when an individual stops breathing
--> severe bleeding of all types
--> Electric shock
When an individual stops breathing an immediate resuscitation is required. This is because if the brain is deprived of oxygen for more than about 4 minutes, permanent brain damage will occur. Therefore artificial respiration (ventilation) should be applied. This can be done following the Cardiopulmonary resuscitation (CPR) procedures and accompanied with an automated external defibrillator (AED) is available to achieve the best chance of survival.
Cardiopulmonary resuscitation (CPR) is a lifesaving procedure that involves the combination of chest compressions with artificial ventilation through the mouth for someone who is not breathing. This should be done first, if the individual is not responding, may be the heart is not beating due to a circulatory arrest, an automated external defibrillator (AED) should be used if available. This easy to use device delivers an electrical shock to the heart which enables it re-establish an effective rhythm.
