Blood pressure lab

Hyperpolarization on membrane potentials of nerves and muscles cause

A slow heart rate because it takes longer to reach threshold ( cell is more negative )

What is the parameter for filtration

Blood pressure

What is the role of blood proteins in the movement of fluid between the blood and the interstitial place?

Blood proteins set colloid osmotic pressure

What is the effect of low potassium levels on the membrane potential of nerves and muscles

Causes cell membranes to be hyper polarized > this makes it harder for an action potential

How do low plasma protein levels produce edema

Causes more filtration and less absorption

Low plasma calcium levels

Causes muscle contractions to not be as strong > causing decreased stroke volume

What is the parameter for absorption

Colloid osmotic pressure

Define colloid osmotic pressure

Colloid osmotic pressure is osmotic pressure exerted by plasma proteins. It is responsible for drawing fluid into the blood and preventing excess fluid loss between blood capillaries and the interstitial fluid, thus helping to maintain blood volume and blood pressure.

How does compression of the ankle decrease inflammation

Compression increases the pressure on outside walls of capillaries > decreases the amount of filtration > increasing absorption

low hematocrit

anemia ( low iron )

How does the application of ice to an injury affect blood flow through the capillaries

Ice causes the vasoconstriction of blood vessels which decreases blood flow to the area then this reduces swelling

How does elevation of the damaged ankle decrease inflammation

It uses gravity to it increase venous return > helps excess fluid into the lymph system

How does the removal of ice affect the blood flow through the capillaries and the cytokines.

Removal of ice brings back blood flow which flushes out the cytokines

Define hydrostatic pressure

The pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity
