When blood leaves the heart and travels through the circulation does the pressure change?

Yes; the blood pressure tends to be highest closest to the heart (actually, the highest pressure in the circulatory system is in the left ventricle) and slowly drops as it reaches the capillaries. However, there is still some blood pressure at the capillaries, which is why the serum can be forced across the capillary wall into the extracellular fluid to exchange nutrients. There is also some blood pressure in the venous system, although it is much lower than the arterial side.

How does the temperature and pressure change inside the earth moving downward from the crust to the core?
Both temperature and pressure increase.
Can blocking atmospheric or oceanic circulation patterns could drastically change climate?

Does a fall in pulse rate affect the pressure?
Do you mean blood pressure? Yes it does like for example when you do drugs or something
How air pressure change by the type of tornado?
If by type you mean Fujita (F) scale rating, then generally the stronger the tornado the lower the pressure.
Why do arteries stretch?
Arteries are high-pressure vessels. However, this pressure is not constant. As the heart pumps blood into the arteries, the pressure dramatically increases. They must stretch to accommodate this change, or risk rupturing.
What travels through a never-ending cycle of change?
Weather.
How can you die from a rapid change in air pressure?
Sudden change in air pressure might lead to death. Sudden change in air pressure will disrupt the blood and air circulation within your body. You might feel dizzy and have nose-bleeding in such cases.
What is the change in speed called when light travels through different mediums?
It is simply called a change in speed.
The colour of light which travels through glass with the minimum speed is?
Light does not change speed when it goes through glass.
How does light travel when it travels through material that doesn't change?
Light will bounce back to you
What is the reasons for the observed changes in blood flow velocity in the different regions of the circulation?
The speed velocity of blood flow changes as blood travels through the systemic circulation. This change can be faster or slower. It is fastest where the cross-section area of the vascular bed is least, and slowest where the total cross-section area is greatest. This slow flow allows nutrient-waste exchange.
When you descend through the earth what two things change?
Temperature and Pressure.
What temperature does sound travel faster in?
That depends on the nature of the medium through which it is traveling and how that medium's density is affected (if it is affected at all) by its change in temperature. The denser the medium, the faster sound travels through it. For example, in a sealed chamber containing a gas, the speed of sound is not affected by temperature unless it gets cold enough for the gas to condense to a liquid. As long as it remains a gas, changes in temparature only affect its pressure, not its density.
How can granite change to metamorphic without changing into sedimentary?
Through heat and pressure
A medium can effect speed of sound by changes in what?
When you change density and temperature you effect the way sound travels through a medium.
What happens to the speed of the light as it travels from the air through the glass and then through the water?
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
What is the difference between refracted light and reflected light?
Refraction is the change in direction caused by a speed differential as light travels through different mediums, or temperature/pressure gradients. Reflection is light directly hitting an object and exiting at the same angle at which it hit.
