Veins
Veins are thin blood vessels that carry blood from various body parts to the heart. These have valves in them to prevent back flow of blood.

Why sluggish flow of blood in veins?
Blood flows slower in veins than arteries because veins have valves.
Veins carry deoxygenated blood back to the heart, whereas the heart pumps oxygenated blood through the arteries to the body. Because it is going to the whole body, this blood needs to be at a high speed and under lots of pressure. Thus the heart contracts and pumps it through thick, muscular arteries under high pressure.
Veins are thinner walled and have valves so that there is no backflow of deoxygenated blood due to the low pressure of the blood in veins. If veins were under high pressure they would gush into the heart and cause it to burst/explode.
What is The medical term meaning incision into a vein to withdraw blood?
Venotomy, venesection, phlebotomy or venipuncture is piercing of a vein to withdraw blood. Venous cut-down is incision of a vein in an emergency to insert a tube to give fluids or other medications.
How can vein collapse be avoided in a geriatric patient?
To avoid vein collapse in geriatric patients, it's essential to ensure adequate hydration and maintain warm ambient temperatures to promote vasodilation. Using smaller gauge needles and employing gentle techniques during venipuncture can minimize trauma to delicate veins. Additionally, positioning the patient comfortably and using appropriate support can help enhance vein visibility and accessibility. Regular monitoring and adjusting techniques based on individual patient needs are also crucial.
What happens if you use a syringe to shoot air in to your arm?
That is an air embolism. If you shoot air into the bloodstream it can cause death. If you shoot it into a muscle it can cause an abcess.
What is a pulmonary vein and what type of blood does it carry?
A pulmonary vein is a vein that carries blood from the lungs to the left atrium heart. It is unique among veins in that it carries oxygenated blood. There is a right and left pulmonary vein that join just prior to entering the heart.
Which vein carries nutrient-rich blood from the digestive system to the liver?
The liver is connected to two blood vessels, one called the hepatic artery and the other the portal vein. The portal vein carries nutrients digested from the gastro intestinal track.

Means the act or practice of penetrating a vein by needle for the purposes of collecting blood samples for laboratory tests as a diagnostic measure or blood donation by an individual to a blood bank, to later be used on patients needing blood suplementation.Venipuncture is used to collect samples of a patients' blood so that it's chemical composition can be tested to determine the cause of a specific illness or condition. Some of the most common tests performed daily are:1. Blood cell count2. Amount of protein, calcium, potassium, and/or glucose present3. Determine the amount of cholesterol in the blood5. Determine BAC (blood alcohol content),6. Determine the amount of oxygen in the blood and many, many more.If alcohol is injected straight into a vein?
Pharmaceutical grade ethyl alcohol is sometimes given IV. Other than the obvious problems of getting drunk (perhaps dangerously so) the alcohol is not a problem. Using alcohol that is not intended for IV use may cause problems from the other contaminants in it.
Why do they put dye through your veins?
Medical procedures involving the use of "dye" through your veins enables the veins to show up more clearly when scanned by a CT/MRI machine, or similar. This is useful when assessing levels of blood-flow around the body, and will show up where any "blockages" may be occurring.
Similar procedures involve ingesting (swallowing) a small amount of "dye"; this type of process would be used to assess the stomach, small intestine and colon.
Usually the "dye" is actually a non-harmful radioactive substance, as opposed to a liquid of a concentrated colour (which is how most people consider "dye"). It is completely harmless, and breaks down within a few hours of being injected.
