Respiratory System PowerPoint Tidal Volume Hemoglobin Diffusion Spontaneous movement of particles from an area of high concentration to an area of low concentration. Emphysema Emphysema is a lung disease that makes it hard to breathe. Pulmonary Embolism Trachea By: Regan Kerr Tidal Volume is the air that moves in and out of each lung. You can measure your tidal volume by displaying your breath on a respirometer graph. Identify the value of the peak and valley of the breath and record the two numbers. Subtract the valley number from the peak number you got for that specific breath. The result will be the tidal volume. Hemoglobin has been proven to contain a high concentration of erythrocyte. Erythrocyte is a red blood cell. Hemoglobin helps spread oxygen, O2, throughout your body. Breastmilk helps tremendously increase hemoglobin reproduction because of its high iron count. Diffusion occurs via a random kinetic movement, it does not require energy. A kinetic movement is a self motioned movement It is referred to as Chronic Obstructive Lung Disease, or COPD. COPD is the fourth leading cause of death in the United States, luckily it is treatable. Pulmonary embolism, or PE, is a sudden blockage in a lung artery. The blockage usually is caused by a blood clot that travels to the lung from a vein in the leg or arm. PE causes low oxygen levels in your blood and damages other organs in your body because of a lack of oxygen. The trachea has 15 to 20 C-shaped bars of hyaline cartilage that prevent it from collapsing Hyaline cartilage is the most abundant of all the cartilage, which is a glossy type tissue. Hyaline Cartilage Bronchi The right main bronchus, about 2.5 cm in length, is shorter, wider, and more nearly vertical than the left because of the positioning of the lungs. The bronchi are supplied by the bronchial arteries and veins, and their organ stimulation is similar to that of the trachea. Trachea The trachea has cervical and thoracic parts. It is about 9 to 15 cm in length. The trachea is usually visible above the arch of the aorta in radiographs, otherwise known as X-rays. Cervical Parts of the Trachea The cervical trachea extends from the lower edge of the cricoid cartilage, below the vocal cords, down to a plane passing from the top of the sternum to the edge of the second dorsal vertebra, A.K.A the back area. Thoracic Parts of the Trachea The thoracic trachea is slightly longer than the cervical trachea. It is located in the upper third of the chest. This segment of the trachea is in close proximity to the large vessels of the mediastinum, sternum in front to the vertebral column. Works Cited
