Place where blood changes from low CO2 to high CO2?
veins
What happens to an oxygen molecule after it has been breathed in?
When the oxygen molecule is inhaled it causes a slight explosion which forces the air into your lungs and then up through your veins which gives you better blood flow to your brain. Sometimes rare genetic disorders cause these molecules to be deistroyed so they're not able to explode and usually the blood flow is a lot worse in the people that have this disorder. This can be fixed with a simple medication that is taken daily.
What is the carrier of food nutrients and oxygen?
blood vessels. they are the pathways or tubes in the body through which blood flows. the blood vessel are of three kinds. these are the arteries, veins, and capillaries. the arteries carry blood away from the heart. the veins bring blood back to the heart. capillaries carry blood rich in oxygen to the tissue, and carry away waste products
When is a syringe method preferred over the evacuated tube method?
when a patient has never blood drawnSyringe allows more control over the amount of pressure exerted on a tinyand/or fragile vein during a phlebotomya. Syringes do not contain a vacuum but are filled by pulling back onplunger, allowing blood to flow into the barrel of the syringeb. The force exerted on the inside of the blood vessel may beincreased or decreased by pulling plunger faster or slowerc. Therefore, the amount of pressure exerted on the inside of the veinmay be controlled by the phlebotomistd. Phlebotomist may control rate at which blood is withdrawn &thereby prevent a patient's veins from collapsing during bloodspecimen collection
Why do vains have valves?
to maintain the back flow of the blood
How is blood flow direction controlled in veins?
There are one-way valves (leaflet valves) in the veins which normally allow blood to flow only back to the heart. Muscle pressure is the main force pushing blood back from the extremities, especially against gravity in the legs. When the valves malfunction or are affected by high blood pressure, the vessels can form varicose (swollen) veins, blue veins, or spider veins.
Is blood flow faster in veins?
Blood flow is faster in arteries than in veins. Blood flow in veins is lower pressure.
Do capillaries have valves to regulate blood flow?
Capillaries do not have valves to regulate blood flow. Veins are the vessel of the circulatory system that have veins to regulate blood flow.
Do the veins carry deoxygenated blood?
No. (Not counting the pulmonary veins) the least "deoxygenated" blood is in the renal veins and the jugular. (Neither the brain nor the kidneys use up all the oxygen in their blood supply.) Blood flow to the skin is sometimes controlled by temperature - heat to be lost - and MAY be less desaturated.
What does ficiliate the flow of blood?
Veins
What is the blood flow through the body controlled by?
THe blood flow is controlled by the brain. Please recomend me.
Which type blood vessels does the blood flow to the heart in?
Veins.
Blood flow from leg to heart?
Veins
What direction does the blood flow in the heart?
there are two main veins that makes the blood flow toward the heart which are the superior vena cava and inferior vena cava.
What prevents blood in the cardiovascular system from going backward?
blood flows into the veins quiet slowly as they are much wider compared to the flow of blood in the arteries which are rather narrow.because of the low pressure of blood on the flow inside the veins there are great possibilities that the blood is likely to flow backwards which may cause complications in the flow of blood.to prevent this from happening the veins contain valves that stop the back flow of blood
Where does Blood flow mostly through?
veins and arteries
Where does the blood flow through?
