What helps maintain normal blood pressure? |
1. Cardiac output (Normal heartbeat) 2. Blood/Fluid volume (Normal blood and fluids) 3. Diameter change of Blood vessels |
|
|
Cardiac Output |
A normal beating heart pumps blood in amounts that are suitable for our needs and that maintains normal blood pressure. Damage to this output will lead to serious drop in blood pressure. |
|
|
Blood Volume/Fluid Volume |
A drop in blood pressure could be caused by a significant loss of blood or fluids (diarrhea/vomiting/sweating). |
|
|
Blood Vessels |
Our blood vessels possess the ability to change their diameter in response to blood pressure drop. This diameter can also change in the presence of an allergen (anaphylactic shock) or bacteria (septic shock), creating a situation in which we have sufficient blood in the body, but since the arteries are dilated, they are not able to carry the Blood to target organs. |
|
|
What happens to our bodies when the blood pressure drops significantly? |
Shock |
