A. A vasectomy usually takes about 30 minutes, and can be done under local or general anaesthetic. Men usually report feeling a mild to moderate ache in their testicles for a few seconds during the procedure. For a few days after the vasectomy the testicles may ache or feel like they have been kicked.
The right and left lung are not symmetrical, since your right lung has three lobes and your left lung has two. The lobes on both sides of your lungs are separated by fissures. The oblique fissure separates the largest lobe, the left upper lobe, or superior lobe, from the one below it. The lower is called the left lower, or inferior, lobe.
Each lung is anatomically divided into lobes, each with a large âlobarâ airway, or bronchus. Each lobar airway divides, into individual segments within each lung. The right lung has 3 lobes: upper, lower and middle lobes; the left lung has 2 lobes: upper and lower. The right lung has 10 segments, the left lung 8 segments. On a microscopic level, each bronchus divides through several generations until it ends in a cluster of small air sacs, called alveoli.
