How would decreased diffusion across the arachnoid granulations affect the volume of the cerebrospinal fluid in the ventricles?
increase
What does moderate generalized volume loss with prominence of the ventricles and cerebral cortical sulci mean?
The cerebral does moderate generalized volume loss with prominence of the ventricles and cerebral cortical sulci. It refers to the brain volume loss.
What is the maximum blood volume contained in the ventricles?
The maximum for both ventricles in an adult male is 70ml.
How does preload affect the stroke volume?
Preload refers to the degree of stretch of cardiac muscle cells before contraction. These muscles exhibit a length-tension relationship. When the cardiac muscle cells are at rest, they are shorter than their optimal length. The most important factor affecting the stretching of cardiac muscles is the venous return, that is, the amount of blood returning back to the heart. Slow heartbeat and exercise can increase the venous return. This will lead to the stretching of the ventricles and it will hence increase the contraction force.As reflected by the Frank-Starling Law, the stroke volume increases with the end diastolic volume. The greater filling volume will lead to the heart to stretch more and this will increase its force of contraction.
How are atria and ventricle differ?
The atria are on the top, and ventricles on the bottom. The atria are smaller, and the ventricles bigger. The atria receive blood coming into the heart, and the ventricles send blood out of the heart. The contraction of the atria end diastole, and the contraction of the ventricles end systole.
What do a bat's auricles do and are they movable?
The auricles increases the volume of the atrium, and yes, they are movable.

What is difference between auricle and ventricle?
uricles are part of the atria and serve to increase the volume of the atria. The atria that they are a part of serve to direct blood into the ventricles and are not very muscular. The ventricles are far more muscular than the atria and serve to pump blood to either the lungs or the rest of the body ( the right and left ventricles respectively).
What does moderate generalized volume loss with prominence of the ventricles and cerebral cortical sulci mean?
The cerebral does moderate generalized volume loss with prominence of the ventricles and cerebral cortical sulci. It refers to the brain volume loss.
What is the maximum blood volume contained in the ventricles?
The maximum for both ventricles in an adult male is 70ml.
When volume is increased does pressure increase or decrease?
Neither. Volume is independent of mass. Effectively, if you increase the volume of a substance you are moving the particles that comprise that substance apart. Eventually, you would have a gas which expands to fill the volume of its container.

What is the purpose of the auricle in the heart?
The Auricle increases the volume of the atrium.Right auricle collects the deoxygenated blood and pushes it to the right ventricle. Left auricle collects the oxygenated blood from lungs and pushes it towards left ventricle.

The atria are on the top, and ventricles on the bottom. The atria are smaller, and the ventricles bigger. The atria receive blood coming into the heart, and the ventricles send blood out of the heart. The contraction of the atria end diastole, and the contraction of the ventricles end systole.
