Term
|
Definition
| If contractility of the heart is decreased what often happens? |
|
|
Term
| afterload is increase = decreased SV |
|
Definition
| If vessels are constricted, what happens do the afterload? |
|
|
Term
heart rate increases
blood vessels constrict
BP increases
the heart has a more forceful contraction |
|
Definition
| What happens to the body during a sympathetic response? |
|
|
Term
heart rate decreases
dilated blood vessels
BP decreases
the heart has a decrease strength with contraction |
|
Definition
| What happens to the body during a parasympathetic response? |
|
|
Term

|
Definition
| What is the cardiac cycle? |
|
|
Term
| The amount of blood ejected by the heart every minute. |

Definition
|
|
Term
| The amount of blood ejected with each ventricular contraction |

|
Definition
| If our SV is increased are CO will be? |
|
|
Term
