Veins carry blood from the heart to the .?
Veins always bring blood from somewhere to the heart. The pulmonary veins bring it from the lungs to the heart and is the only time when it carries oxygenated blood. All other veins carry deoxygenated blood from the body tissues back to the heart.
You might want to research DVT (Deep Vein Thrombosis). It's a condition where there is a blood clot in a deep vein, and is generally diagnosed in the legs. If your veins have any of these symptoms, see your doctor immediately:
-painful legs,located to one area
-swollen areas
-discoloration around the vein
-veins seem swollen or engorged
With any issue like this, its best to consult your PCP to figure it out. If its a clot, it needs immediate attention. Good Luck!
The elastic arteries are huge and allow for large amounts of blood to go through them. They need elastic fibers so they can stretch and return to their original state--basically they want to make it easy for large amounts of blood to pass through. Muscular arteries are responsible for getting blood to various locations, so they contract and dilate according to the immediate needs of the tissue they are supplying.
Whats the function of veins and what are the effect of sympathetic activity on veins?
veins help with sex and the effect of sympathetic activity on veins is that it will help with sex
Its called vascularity, the appearance of veins on the skin. If you lift weights or exercise often, you tend to get increased vasculiarity in the short term, which leads to increased vascularity in the long term. Also big veins can prevent blood clotting.
My goldfish has red blood in its tail fins?
Maybe you are seeing natural red rays in the fishes fins? If not then there is something wrong with the water. Change some (50%) water daily and see if the red markings disappear. Dont change all of the water.
How do you get red of veins popping out in your arms?
if your saying "Get Rid of." It depends.
-You have high blood sugar (Get your heart running and do excerise to lower it)
-Spider Veins (Not sure how to get rid of but has something to do with poor Circulation)
-Poor Circulation ( You have to see what a doctor can do on that)
- Too much oil or sugar in your veins ( Eat healthy, excerise)
High blood sugar may include diabetes.
Its either one of those, I recommend a doctor for check up. But there are some positive signs
- You work out (veins usually pop out)
- Your a little scrawny ( veins will pop out because not much meat on your bones to cover it)
But still have a doctor check up on you. You'll never know if you don't get checked up
Other way around. Valves appear in veins to keep the blood flowing in one direction to the heart.
Which blood moves through a person's veins and arteries?
Arteries usually carry oxygenated blood from the heart to the rest of body. Veins usually carry to the heart blood that is depleted of oxygen and full of CO2 and other impurities.
There are two exceptions. The pulmonary artery carries "dirty" blood from the heart to the lungs. The pulmonary vein carries oxygenated blood from the lungs to the heart.
What is the major function of valves in veins?
To stop the blood travelling the wrong way down the vein. One way system lol.
Arteries are the opposite of veins. "Arteries away my boys!" "Back to the heart, and you're a vein!"
Do veins move blood through the heart?
Not exactly.
Veins move blood back to the heart (from the body or from the lungs)
Arteries move blood away from the heart (to the body or the lungs)
The heart is a large muscular organ that "pumps" the blood through a series of chambers (atria and ventricles) by contracting the different chambers at specific intervals (your heart beat) to change the volume.
The blood moves from a high pressure (contracted) chamber to a lower pressure artery.
The path of blood through the heart is this: Into the right atrium via veins from your body, to the right ventricle where it is moved to the lungs to be oxygenated, then back to the left atrium and ventricle where it is pumped to the rest of your body.
I hope this all makes sense.
i have a possible guess. i think its just a relazation method.
It means that you have Syphillis.
Why do you have veins that have oxygen in them?
The only veins that have oxygen in them are the pulmonary veins. The definition of a vein is a blood vessel that carries blood to the heart. This blood is usually de-oxygenated, but the pulmonary veins are the exception.
What color is the blood in the veins?
Some will say that the blood is blue in the veins because your veins are blue looking. This is incorrect. The blood is in fact red inside the veins, the veins just look blue due to the way the light passes through the fat and skin cells above.
