evaluate how the heart can be compared to a mechanical pump

Sagot :

Evaluation of how the heart can be compared to a mechanical pump:

  • The human heart is an organ that pumps blood throughout the body while a pump is a device which moves fluids by mechanical action.
  • The function of the heart is to circulate blood through two pathways: the pulmonary circuit and the systemic circuit while Mechanical Pump performs two functions. First, its mechanical action creates a vacuum at the pump inlet, second, its mechanical action delivers this liquid to the pump outlet.
  • The heart needs oxygen in order to keep functioning. The heart contains electrical "pacemaker" cells, which cause it to contract to produce a heartbeat as to the mechanical pump needs power or electricity in order to work and provide you service. So basically, the two both need a component in order to work efficiently.

Parts that make up a human heart

The heart divides into a right and left side.  The right side associated with the pulmonary circulation and the left side associated with the rest of the body or systemic circulation.

The four chambers of the heart:

  3. left atria
  4. left ventricle

  2. pulmonary semilunar valve
  3. bicuspid/mitral valve
