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.
They need to have a q system perspective in order to work.
Answer:I expect them to check if the 61 year old is still breathing If the person isn't breathing or is only gasping, they will administer CPR.
Give CPR: Push hard and fast Push down at least two inches at a rate of 100 to 120 pushes a minute in the middle of the chest, allowing the chest to come back up to its original position after every push.
Answer: Because social characteristics such as class, gender, and ethnicity influence life chances, they are allocated unequally among individuals and groups. People in higher social classes have a better likelihood of getting adequate healthcare and decent housing than those in lower social classes.
