Question 57 How do the circulatory system and immune
system work together to respond to an injury?
Increased blood flow allows for an
increase in the exchange of O2 and CO,
at the site of the injury.
Increased blood flow kills healthy cells
which prevents infection at the site of the
injury
Increased blood flow carries white blood
cells to the site of the injury.
Increased blood flow removes infected
cells from the body at the site of the
injury.

Both fight over infection and work on the rebuild of body tissue

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
