Ch 14 part 2 - Hydrostatic Pressure and Blood Flow Concepts

The ______ gradient between the arteries and the veins provides the force that drives the movement of blood through the vasculature.

A ______ column of water demonstrates the concept of hydrostatic pressure.

The ______ will tend to flow down the pressure gradient from the column with more hydrostatic pressure to the column with less hydrostatic pressure.

The rate of flow does not depend on the ______ pressure in either column.

The ______ Difference, or the pressure gradient, is the same in both columns, so the rate of flow is the same.

In a hydrostatic column, the flow of water from one column to another eventually ______ the pressure gradient.

The slope of the line between two points on this curve (such as A and ______) represents the compliance of the vessel (the change in volume divided by the change in distending pressure).

A steeper slope between the 2 points means greater ______, which indicates that the vessel expands easily (i.e., the change in volume is high) due to a given change in distending pressure.

______ hove low compliance, which means that they recoil when they are stretched out.

Low compliance means that the change in volume divided by the change in ______ is low.

This means that small changes in volume result in significant changes in ______ and that large changes in pressure result in small changes in volume.

The flow rate of a liquid through pipes is directly proportional to the ______ between the pressures of the two ends of the pipe.

The flow rate of a liquid through pipes is inversely proportional to the ______ of the pipe.

Blood flow is higher when the ______ difference between the two ends of the tube is higher.

Blood flow is higher when the ______ to blood flow is lower.

When you faint, the heart no longer has to overcome the ______ of gravity.

At its most basic level, blood flow through blood vessels follows the physical laws describing the blood flow of any ______ through any system of pipes.
