Right bronchus when compared to left bronchus is
**Core Concept**
The right and left bronchi are the two main airways that lead to the lungs, and they have distinct anatomical characteristics that differentiate them from each other.
**Why the Correct Answer is Right**
The right bronchus is shorter and more vertical than the left bronchus, which makes it narrower and more prone to obstruction. This is because the right bronchus is more directly in line with the trachea, making it easier for foreign objects to enter the right lung. The right bronchus also has a more acute angle with the trachea than the left bronchus, which contributes to its narrower diameter.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the right bronchus is not wider than the left bronchus. In fact, the opposite is true: the right bronchus is narrower than the left bronchus due to its shorter length and more vertical orientation.
**Option B:** This option is incorrect because the right bronchus is not more horizontal than the left bronchus. Instead, the right bronchus is more vertical than the left bronchus, which makes it more prone to obstruction.
**Option C:** This option is incorrect because the right bronchus is not longer than the left bronchus. In fact, the opposite is true: the right bronchus is shorter than the left bronchus due to its more vertical orientation.
**Clinical Pearl / High-Yield Fact**
It's worth noting that the right bronchus's more vertical orientation makes it more susceptible to obstruction by foreign objects, which is why the right lung is more commonly affected by pneumonia and other respiratory infections.
**Correct Answer:** C.
