What else can I help you with?
Is the partial pressure of oxygen in the arteries greater than the partial pressure of oxygen in the veins?
Yes, the partial pressure of oxygen in the arteries is typically greater than in the veins. This is because oxygen is being delivered to tissues by the arterial blood, so the arterial blood has higher oxygen levels compared to the venous blood, which has already passed through the tissues and picked up carbon dioxide.
What is an endiogram?
It's a test done to identify cloggs in arteries. A coloured liquid is passed through your veins and is checked with computer assisted technologies as to where the block is.
What keeps the blood pumping in the right direction?
the contractions of the heart push the blood through vents, which close after the blood has passed to prevent back flow. these vents are also in Arteries.
Why atherosclerosis in artery not in vein?
The blood in veins has already passed through the capillaries which are smaller. anything that passes through the capillaries is too small to form one, and if it was big enough to clause blockage, that would occur in the arteries, before it reached the capillaries
How aircraft engine works?
Turbine engines work by the principle of Bernoulli - Pressure total = Pressure Dynamic + Pressure Static. Turbine engines compresses the air and thereby increase the Static pressure and the Dynamic pressure in different stages of the engine. Once the air has passed the LP compresser and the HP Compresser is passes into the combustion chamber, where fuel is added to provide thermal energy to the air. At this point the Dynamic pressure will rise and will be boosted into the turbine which drives the entire engine. The remaining energy will be send through the exhaust which has a convergent shape to further increase the dynamic pressure of the air.
What is a vessel that returns blood back to the heart after it's passed through the capillaries?
ARTERIES carry blood TO the capillaries throughout the body, whereas VEINS carry blood FROM the capillaries and back to the heart. Tip for rememering: A-->V (alphabetical order: arteries-->veins)
How much energy is passed from one trophic level to the next where does the rest go?
Roughly 10% of energy is passed from one trophic level to the next, with the remaining 90% lost as heat through metabolic processes. This process is known as the 10% rule in energy transfer in ecosystems.
What causes sickle cells to occur?
bad genes passed on through generation i believe when the red blood cells run out of oxygen they change shape and get trapped on the veins and arteries causing serious problems even death
What gas glows when you put electricity through?
When electricity is passed through neon gas at low pressure, it emits a bright orange-red glow. This phenomenon is used in neon lights and signs.
The specific wavelengths of light seen through a prism that are made when a high voltage current is passed through a tube of hydrogen gas at a low pressure is a?
The specific wavelengths of light seen through a prism when a high voltage current is passed through a tube of hydrogen gas at low pressure is known as the hydrogen emission spectrum. It consists of discrete lines of light representing the different transitions of electrons between energy levels within the hydrogen atom.
Is neon a colored gas?
Neon is colorless gas ,however, under low pressure ,it glows a bright orange-red if an electric current is passed through it.
Can you feel pulse in veins but not in arteries?
Veins take blood back to the heart. So the pluse created from the heart beating is felt as a surge of blood in an artery. by the time the surge of blood has passed through the network of arterioles and capillaries the surge has died down.
