The SA Node is the heart's normal pacemaker. When the SA Node depolarizes, electrical signal spreads through the atrial muscle causing contraction.
Explanation:
Inherent rhythmicity / automaticity - The property of the pacemaker cells of the heart to start electrical sequence of depolarization and repolarization.
SA Node or Sino-atrial Node generates the electrical signal.
The electrical signal passes through internodal pathways, atrial fibres, atrioventricular node (AV Node), the bundle of His, Purkinje fibres, right bundle branch, left bundle branch.
Systole - Contraction of cells when the electrical signal of depolarization reaches the contractile cells.
Diastole - Relaxation of cells when the electrical signal of repolarization reaches the myocardial cells.
Answer: Absolute Method
Explanation:
Absolute method is the method to access muscular endurance in which the weight is adjusted according to the individual's strength ability.
Muscular endurance can be defined as the muscles's ability to generate the sub maximal force for a certain period of time.The wight is adjusted according to the person ability and the endurance is calculated by the using the absolute method.
Hence, the correct answer is option A
I don't even think so because waste has to come out
Answer:
This process can take up to two years. The scar won't disappear completely and you'll be left with a visible mark or line. Fine-line scars are common following a wound or after surgery.
