Veins

Saphenous vein, internal mammary and radial artery.

== == # Find a vein. # Swab the area with disinfectant. # Consider tying a light, easily removed tourniquet proximal to the point of insertion, in order to raise the vein. # Attach needle to source. Remove cap and flush needle to remove air. # Using the sharp side of the needpoint in closest contact with the vein, insert needlle into vein, far enough to completely enter the vein but not so far as to puncture the opposite wall of the vein. Insert at about a 30 degree angle or less. # Watch for veinous blood (dark red or purple) to register in the IV or syringe, to ensure the needle in is the vein. In an IV rig, blood pressure should be sufficient. With a syringe, you may need to draw up on the plunger a little. No blood means you're not in the vein -- start again. # Remove tourniquet # Start IV. # Observe for adverse reactions. # If the needles doesn't remain in place, dispose of as sharps.

You bleed A LOT when you have a miscarriage and during your period you also bleed bright red so see a doctor if unsure. Take a pregnancy test 2 weeks after.

Your blood is bright red in the artery and dark red in veins. You do not have [ blue blood ] . It only appears blue because the veins which are white are are carrying dark red blood and being viewed through the skin which difuses the light and makes them appear blue.

that is partly true but I have herd from all my teachers that your blood is blue in the arteries. Which when you get cut the air puts oxygen in the blood stream that makes the blood turn red.

answer #2

The statement that blood is blue inside the body and turns red when in contact with blood makes little sense. How can this be so when blood itself is used to transport oxygen throughout the body? It is not possible for blood to be blue inside the body as well as carry out one of it's main functions.

Answer#3

Actually blood is red in the arteries and blue in the vein. Blood in the artery has already combined with oxygen whereas blood in the vein has yet to receive oxygen. So in fact there is both red and blue blood. When a vein is cut open it hits oxygen in the air causing it to turn red.

Answer#4

The protein hemoglobin, which carries oxygen in the blood, changes shape when it binds oxygen. When it changes shape, it absorbs different wavelengths of light, making it change color. When blood is exposed to air, much more of the hemoglobin absorbs oxygen than had in the vein the blood came from (in the veins, the hemoglobin has already given up most of its oxygen to the body). Therefore, the blood turns red.

This also means that blood in the body, once it has been oxygenated, is also red, though much more so when it reaches open air. I think it would be a fun experiment to put your hand in a vacuum chamber with a tight seal around your wrist and prick your finger to see the difference in blood color.

Coronary veins have oxygen rich blood. Hope I helped (:
no, they carry deoxygenated blood to the coronary sinus.

oxygen is the answer

The three types of blood vessels are the capillaries, arteries, and veins. The veins are the ones that have the lowest pressure.

Arteries always carry blood away from the heart. They also carry only oxygenated blood except for the pulmonary artery. They have thick walls due to the pressure created.

Veins always carry blood towards the heart, they mostly carry de-oxygenated blood except for the pulmonary vein. Vein walls are not so thick.Capillaries are extremely small and its walls are only one cell thick. They join the organ to the vein or the artery, and join the pulmonary vein and pulmonary artery at the lungs.

The Pulmonary arteries

The heart chambers are not called arteries and veins. Heart chambers are atria and ventricles.

They do not carry the sickle cell allele, a. Individuals that are heterozygous have the advantage of being more resistant to malaria than homozygous dominant individuals, but are not affected by the disease.

Many puncture wounds to the heart are fatal because the blood leaks out into the body cavity instead of being pumped to either the ventricle (if it is an atrial puncture) or the rest of the body like in this example. Of course this depends on the severity of the injury, too.

In a basic sense, a stab wound to the ventricular muscle tissue could cause impaired function (would not contract and pump properly) or loss of function (so much damage that it could not contract at all) - the first would be very serious and require immediated medical attention to repair; the latter would be, essentially, instantly fatal. The blood in the chamber could also leak out into the chest cavity (internal bleeding), which can also be fatal.

they are in the arteries

I'm really not sure, but it could be due to a coronary artery block where your right coronary artery isn't getting the necessary blood from you aorta...But that is just a guess...I would def. go to a cardiologist

YES! veins are more compliant than arteries. it means they are more capable of adopting their lumen size with changes in blood volume inside their lumen .when blood volume increase inside a vein lumen it easily expands and accepts whatever amount of blood reach and when blood volume decreases squeezes and adopt its lumen size for that amount of blood .

but when we are talking just about arteries and want to compare one artery to another artery ,we should know that aorta is most compliant artery,remember the farther away from heart the less elastin in artery wall hence less compliance.

The heart chambers are called atria and ventricles. Arteries and veins are blood vessels.

veins are important because they carry de-oxygenated blood from all parts of the body back to the heart , which sends blood to the lungs which then returns to the heart so that oxygen can be carried in the blood to all parts of the body. ( the body uses it in cellular respiration)

His most important discovery was that arteries carry blood although he did not discover circulation.

The superior vena cava brings blood back from the upper part of the body. The inferior vena cava drains the rest of the body.

none. there are 4 pulmonary veins and they all empty into the left atrium, except in cases of congenital heart disease with anomalous pulmonary venous return to the right atrium.

To enable adequate movement during mydriasis (dilation of the pupil) and miosis (pupil closing).

VEINS ~ It's Arteries OUT and Veins BACK

i had same problem and my doctor said it ws just hemrhoids.

The largest vein is the vena cava, which is made up of two parts, the superior (that runs along the head) and the inferior(which collects blood from the lower part of the body)
