Biology 2 - Intro to Hydrostatic Pressure and Partial Pressure Gradients (Exam 3)

What does hydrostatic pressure gradient focus on?

The pressure of a fluid inside a container.

What is an example of hydrostatic pressure in action?

A water balloon expanding upon the filling of water.

What can "container" be within the context of hydrostatic pressure?

A cell or something like an organ, such as blood vessels

What does Hydrostatic Pressure Gradients measure specifically?

How much the fluid is pushing on the walls of the cell/container

What's an example of Hydrostatic Pressure Gradient being used as a measurement?

Blood pressure (Blood pressure is found via measuring the Hydrostatic Pressure within the arteries)

In regard to Hydrostatic Pressure, smaller container = ...?

More Pressure! Because there's less space for the fluid to spread without pushing against the walls of the container

Water pressure within cells can be toxic when...

It's either exceedingly high or exceedingly low

What does Osmosis focus on?

The movement of water between the cells and environment

What does the blood vessels utilize to keep blood moving in a specific direction?

Hydrostatic Pressure Gradients (Blood moves from higher concentration to low concentration)

Partial Pressure Gradients

Focuses on gradients created by gas particles (Such as OX)

What Law does Partial Pressure Gradients utilize?

Dalton's Law

What is Dalton's Law?

The total pressure of a mixture of gases is the sum of the individual pressures.

How is total pressure calculated according to Dalton's Law?

Ptotal = Gas 1 Pressure + Gas 2 Pressure + Gas 3 Pressure + ...

What is the partial pressure directly proportional to?

It's percentage in the mixture of the gases

Ex. If 8 out of 15 gases is green, which is 53%, then the Partial Pressure of the green gas...?

53 mmHg
