Overview of Blood Pressure
Blood pressure is mainly the pressure exerted on the walls of this type of vessel.
What is an artery?
The measurement of the pressure of blood circulating against the walls of the arteries.
What is blood pressure?
The average blood pressure through one cardiac cycle
What is Mean Arterial Pressure?
What is the artery that a blood pressure cuff is most commonly used on?
What is the Brachial Artery
Net hydrostatic pressure minus net osmotic pressure.
What is Net Filtration Pressure (NFP)?
If your blood pressure reads consistently over 140/90 mmHg, what condition would you be diagnosed with?
What is hypertension?
This is the type of blood pressure that is the first number (or top number) in a blood pressure reading.
What is systolic blood pressure?
The average mean arterial pressure in a healthy adult.
What is 70-100 mmHg?
Vasodilation in vessels causes resistance to _______________
What is decrease?
Physical pressure of blood flowing through the vessels or of fluid in interstitial spaces.
What is hydrostatic pressure?
What is one cause of hypotension?
dehydration
heart failure
shock
The measurement of blood pressure when the heart is relaxed.
What is Diastolic?
The supply of oxygen to and removal of water from the cells and tissues of the body as a result of blood flow.
What is perfusion?
These structures make the sounds heard when listening to a heartbeat.
What are valves?
Movement of solutes (plasma or tissue fluid) through a membrane (plasma membrane) in the presence of a non-diffusible solute (large proteins).
What is osmotic pressure?
Where are the two main locations for baroreceptors during blood pressure regulation?
What are the aortic arch and carotid arteries?
The part of your brain primarily responsible for blood pressure regulation.
What is Medulla Oblongata?
This hormone acts on the kidneys to increase the rate of urine production and Na+ loss in the urine, leading to decreased blood pressure.
What is Atrial Natriuretic Hormone (ANH)?
An increase in stroke volume causes blood pressure and cardiac output to ____________
What is increase?
Interstitial osmotic pressure PULLS filtrate from the ___________ and into the _____________. Depends on the plasma protein _________.
Blood vessels
Interstitial space
Albumin
What does RAAS stand for?
What is the Renin-Angiotensin-Aldosterone System?
This hormone acts on the kidneys, stimulating the retention of more water from the urine, which increases blood pressure.
What is ADH?
One of the formulas to calculate mean Arterial Pressure
MAP = CO × PR
MAP = HR × SV × PR
Lack of oxygen causes vasomotor center to become inactive; extensive vasodilation follows with a drop in blood pressure in this regulatory mechanism.
What is the CNS Ischemic Response?
Interstitial hydrostatic pressure PUSHES filtrate from the ________ into the __________________
Interstitial fluid
Blood vessels
