You can find a sire (male) or a bitch (female) for Schnauzer breeding by speaking to other reputable breeders or your veterinarian. You can also use your own Schnauzers if they come from different parents. Make sure both dogs are registered, in good health and have pleasant temperaments before breeding.
Distinguish between the right and left lungs based on their lobes, fissures, and lobules. Human lungs are located in two cavities on either side of the heart and are separated into lobes by fissures. The two lungs are not identical. The right lung has three lobes and left has two lobes. They are further divided into segments and then into lobules. Lobules are hexagonal divisions of the lungs that are the smallest subdivision visible to the naked eye.
Middle Lobe Lung. The lung consists of five lobes. The left lung has a superior and inferior lobe, while the right lung has superior, middle, and inferior lobes. Thin walls of tissue called fissures separate the different lobes. Only the right lung has a middle lobe. As the name implies, this lobe is located between the upper and lower (also called the superior and inferior) lobes. Each lobe receives air from its own branch of the bronchial tree, called lobar (or secondary) bronchi.
