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 located in two chambers of the thoracic cavity on either side of the heart. Though similar in appearance, the two lungs are not identical, nor wholly symmetrical. Fissures are double folds of pleura that divide the lung into lobes. There are three lobes in the right lung and two in the left lung. The lobes are further divided into segments and then into lobules, which are hexagonal divisions of the lungs that are the smallest visible subdivision.
