These ducts contain alveolar sacs which contain multiple alveoli. The Respiratory membrane has 3 parts. The Squamous Epithelial lining, the endothelial cells, and the fused basement membranes. The left lung has 2 lobes where as the right lung has 3 lobes. The apex of the lungs is blunted/round and extends into the base of the neck and above the first rib. https://padlet.com/tlcarlson1/7pedi514e0og/wish/357266670 2019-05-06 16:21:23 UTC https://padlet.com/tlcarlson1/7pedi514e0og/wish/357266670 https://padlet.com/tlcarlson1/7pedi514e0og/wish/357266834 External respiration is one of the process of respiration.All process in gas exchange of oxygen and carbon dioxide between the body’s fluids and external environment.Purpose is to meet respiratory demands of cells 3 steps 1.)breathing 2.)Gas diffusion 3.)Transport of oxygen.Internal respiration is the absorption of oxygen and release of carbon dioxide.The abnormalities are Hyoxia is the decline of oxygen leading to lack of metabolic activates.Anoxia is when oxygen supply cut off completely cause rapid cell death.   ]]> 2019-05-06 16:21:44 UTC https://padlet.com/tlcarlson1/7pedi514e0og/wish/357266834 https://padlet.com/tlcarlson1/7pedi514e0og/wish/357268894 The nose contains external nares (also known as nostrils). The nose leads into the nasal cavity. The nasal septum divides the nose into 2 halves the left and the right. Exposer to debris/ allergies causes rapid mucus production which results in a runny nose. The throat leads into both the respiratory and digestive tracts. There are 3 subdivisions the nasopharynx, the oripharynx, and the larngopharynx. The trachea takes air into the lungs and through the bronchis]]> 2019-05-06 16:25:46 UTC https://padlet.com/tlcarlson1/7pedi514e0og/wish/357268894
