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.
The lungs are divided into lobes, the left lung having two (the left upper lobe and the left lower lobe) and the right having three (the right upper lobe, the right middle lobe, and the right lower lobe); these are further subdivided into bronchopulmonary segments, of which there are about 20.
