Article: Parallel to the larynx and oropharynx is the esophagus (part of the digestive system) but should be included in your illustration as a low-contrast color. At the mandibular angle, a small “flap” should be noted; this is the epiglottis, which covers the trachea when swallowing to prevent debris from entering the lungs. Draw a flat kidney bean shape following the outline of the base of the lungs. The diaphragm is a muscle that contracts during inhalation and relaxes during exhalation to modify pressure in the lungs. Segment the right lung into 3 curved sections (draw the oblique and horizontal fissures) and the left lung into 2 curved sections (draw the oblique fissure) as distributed below; these segments are called lobes. Extend the branching of the bronchus in each lung into a secondary bronchus in each lobe. Then extend this secondary branching with smaller bronchioles.  It is helpful to do each lobe branch in a new color to distinguish the branching pattern. Attached to these bronchioles are alveoli, which appear as small grapes. Detail several of these and then extend a microscope box away from your diagram to illustrate this structure more clearly. Redraw a segment of the bronchioles and attached alveoli in the microscope box. The bulbous “grape” like structures of the alveoli are called alveolar sacs, and the segment of branching immediately before the alveoli are called alveolar ducts.  In addition to these structures, draw an overlay of the pulmonary artery (red) and pulmonary vein (blue) leading into the arteriole and venule capillary system.     {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/e\/e3\/Capillaries_respsyst_gb2653.png\/460px-Capillaries_respsyst_gb2653.png","bigUrl":"\/images\/thumb\/e\/e3\/Capillaries_respsyst_gb2653.png\/558px-Capillaries_respsyst_gb2653.png","smallWidth":460,"smallHeight":462,"bigWidth":"558","bigHeight":"560","licensing":"<div class=\"mw-parser-output\"><p>Image by: Uploader<br>\nLicense: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by\/3.0\/\">Creative Commons<\/a>\n<\/p><\/div>"} Draw lines away from each structure to an open space using a ruler or straight edge. Clearly label each structure or region correctly. For more complex drawings, it is sometimes beneficial to label structures numerically and then provide an organized key.

Article: Clean all tools used for cutting with warm soapy water. Sterilize the tools by wiping them with alcohol. The type of tool you use will depend on the plant, but common tools include pruning shears, scissors, razor blades and sharp knives. There are several different types of cuttings that can be used to propagate herbs. Determine the type of cutting you desire, and cut the stem accordingly. Regardless of the type, the cut should be at an angle to maximize the cambial tissue exposed to the soil. Cut right below a node, which is a joint or growing point of the stem from which side branches and leaves may grow.  Remove a tip cutting. A tip cutting is removed at the end of a stem. The plant will grow upward and often produces a single vertical stem. A tip cutting is ideal for creating a topiary. To remove a tip cutting, cut about 5 or 6 inches (12.7 or 15.2 cm ) from the tip of a stem. The stem can be a main stem of the plant or a healthy side shoot. Take a sectional cutting. A sectional cutting is from the middle of the stem, so it has 1 cut on each end. Herbs propagated from sectional cuttings typically are bushy because they grow through side shoots. Slice the upper portion of the cutting straight across the stem, and the lower portion of the cutting at an angle. This helps in recognizing the top of the cutting from the bottom. You can take a sectional cutting with a single node, or with several nodes. Remove a basal cutting. A basal cutting is an entire side shoot that is about 6 inches (15.2 cm) long and typically unbranched. Basal cuttings tend to root quickly because the cutting is younger than the main stem. Basal cuttings typically grow up in direction, similar to a tip cutting. Remove a basal cutting where the side branch meets the main stem. Take a heel cutting. A heel cutting is a basal cutting with part of the main stem attached. To remove a heel cutting, hold a side shoot where it connects to the main stem, and pull down so that a shallow strip of the tissue from the main stem peels off with the shoot. The tissue from the main stem encourages rooting and is not likely to damage an established plant. Do not take 2 heel cuttings opposite from each another or you may weaken the stem. Remove all side shoots and leaves from approximately the lower two-thirds of the stem. Stripping the stem creates a wound at each node, which exposes more cambial tissue and encourages rooting. Removing the leaves and stems also helps to prevent root rot.
