Because it is easier, safer, and less painful to puncture a vein than an artery. The vein is larger than the artery and has a thinner wall. The artery is covered in a muscular layer, while the vein is not. The angle that you would have to use to safely enter an artery would be awkward if sitting across from a patient, while the angle of entry for a vein is straight on.
veins are the blood vessels which are much closer to body surface so its quite easy to inject required chemical in that vessel...also veins carry blood to heart so any chemical injected into the veins is carried to heart where it mixes with other blood and then carried by arteries from heart to the body parts.....generally injected fluid is in concentrated form so if we inject it in arteries,there may be possibility that concentrated fluid damage the tissue......U MUST GIVE YOUR VIEWS ABOUT MY ANSWER,,I WILL LIKE IT.......
The fluid in our bodies is composed of 0.9 Sodium Chloride. An individual will recover from dehydration much quicker when given a saline solution rather than just plain water.
The saline water is more viscous.
because of salt content water is saline
No, brackish water is not more saline than ocean water.
Cough, use saline lavage through nasal passages, gargle with salt water.
Normal saline
saline solution is salted water with 0.85% of salt
Not sure what you are using saline solution for but i would say that saline solution is steril and water is not.
Saline solution is a mixture of salt and water.
Saline is distilled water with salt added into it. Dehydration isn't just the excessive loss of body water, it's also an electrolytic imbalance. When the body is dehydrated, salts have been depleted.
The term "saline" just means salty. A saline solution is water with salt in it. (This is not necessarily table salt, NaCl, but can be other salts as well.)
Saline is a solution that is made of sodium chloride and water. It is also known as salt water, or sterile salt water.
