What is Laslow's hierarchy?
dybincka [34]
Maslow's Hierarchy of Needs is a system that lists the needs felt by every human being, in order of ease of accomplishment. Our basic survival (physiological) needs (food, water, shelter) are on the bottom. Next up is our safety needs (being able to live without fear of danger), followed by love/belonging needs (the need to have people who you support, and whom support you). After that comes esteem needs (the need to be supportive of your own choices). Finally, at the top of the list is the need for self-actualization. This is the need to feel like your life has significant meaning, and that you have done something for the greater good of humanity. This is a rare need to meet.
Hope that helped! =)

What is the electrical pathway of the heart, in order? NOTE- this includes pacemaker and conduction components.
s2008m [1.1K]

Answer:

The correct answer will be option A.

Explanation:

The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.  

This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.

Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.

Thus, option-A is the correct answer.
