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.
What else can I help you with?
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.
Does the speed of lightning go up or down as it travels through the atmosphere?
The speed of lightning does not change as it travels through the atmosphere. Lightning travels at the speed of light, which is approximately 186,282 miles per second.
Why can the refractive index of water change?
The refractive index of water can change with factors like temperature, pressure, and the presence of impurities or contaminants. Changes in these factors can alter the density and molecular structure of water, affecting how light travels through it and thus causing variations in its refractive index.
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 happens to light when it travels through transparent object?
When light travels through a transparent object, it is transmitted through the material without being absorbed or scattered. The speed of light may change as it passes through the object, causing the light to refract or bend.
Why does light refract when it travels through water?
Light refracts when it travels through water because the speed of light changes as it passes from one medium to another with a different optical density. This change in speed causes the light to bend, or refract, resulting in the change in direction of the light rays.
When you descend through the earth what two things change?
Temperature and Pressure.
When light is travelling through a medium it travels in a?
When light travels through a medium, it travels in a straight line until it encounters a boundary between two different media, where it may refract, reflect, or scatter. The speed of light may change depending on the medium it is traveling through, which can affect its direction and intensity.
How does sound refract as it travels through different mediums?
Sound refracts as it travels through different mediums by changing speed and direction due to differences in density and temperature. This causes the sound waves to bend, resulting in a change in their path.
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.
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.
How can granite change to metamorphic without changing into sedimentary?
Through heat and pressure
How does a sound wave move through molecules?
A sound wave moves through molecules by causing them to vibrate back and forth. As the sound wave travels through a medium, such as air or water, it creates areas of high and low pressure, forcing the molecules to compress and expand in a wave-like motion. This vibration is then perceived by our ears as sound.
