As a medical professional, I can tell you that an IV, or intravenous line, is typically inserted into a vein. The most common sites for IV insertion include:


1. Veins of the arm: The cephalic, basilic, or median cubital veins are often used because they are superficial and easily accessible.

2. Hand veins: Sometimes veins on the back of the hand are used, especially in children or when arm veins are not accessible.

3. Antecubital fossa: The area inside the elbow where the median cubital vein is located can also be used, although it may be less comfortable for the patient.

4. Scalp veins: In infants, veins on the scalp are commonly used due to their accessibility and size.

5. Foot veins: In some cases, veins in the foot may be used if other sites are not available.

It's important to note that the choice of insertion site depends on the patient's condition, the size and type of the IV catheter, the intended duration of the IV therapy, and the type of fluid or medication being administered.
