The carotid is located on the neck while the rectal is on the rectum
Doctor preference
They are the same thing.
Rectal is more accurate because it takes the core body temperature.
The carotid arteries are very similar in pigs and humans. The cardiovascular system is conserved across all mammal species including pigs and humans.
No they are separate with different functions. The cartoid carries oxygenated blood to the brain and the jugular returns the blood to the heart to be reoxygenated. That's why they show up as red and blue in diagrams of the two arteries.
The bifurcation (splitting) of the common carotid artery is in line with/at the level of the intervertebral disc between the third and fourth cervical vertebral (between C3 and C4).
No. Usually there is about a degree difference with the rectal temperature being about 1 degree higher.
They are not in time with each other due to their relative positions from the heart. The carotid being closer to the heart will be felt before the radial, although the difference is minute.
The Carotid pulse is found in the neck. The Radial pulse is found in the wrist.
The tastes differ. An oral thermometer has a longer slender end that's inserted (into the mouth), compared to a rectal thermometer that has a short bulbous end inserted (into the rectum). The bulb reduces the chance of tearing the rectal wall, especially in infants. Some digital models have a setting for rectal vs. oral on the unit. The rectal temperature is known to be a little warmer and more accurate to body temperature. If you still have a glass and Mercury thermometer, be aware that mercury is a deadly toxin, and consider replacing the thermometer with a digital model.
Usually the heart, or the carotid pulse is good also
the carotid artery passes through the carotid canal to the brain
