Explanation:
The Respiratory System
The thoracic cage, sometimes called the rib cage, is a bony structure that is narrower at the top and wider at the base. It is held in place by the thoracic vertebrae of the spine in the center of the back and by the sternum in the center of the anterior aspect of the body. The first seven ribs attach directly to the sternum and are called the true ribs. Ribs 8, 9, and 10 fasten one to another, forming the false ribs, and ribs 11 and 12 are the “floating” ribs, or half ribs, because their only attachment is to the thoracic vertebrae. At the base or floor of the rib cage is the diaphragm, a musculotendinous membrane that separates the thoracic cavity and the abdominal cavity (Figure 46-1). The respiratory system is divided into two anatomic regions, the upper respiratory tract and the lower respiratory tract.
Upper Respiratory Tract
The upper respiratory tract, which transports air from the atmosphere to the lungs, includes the nose, pharynx (throat), and larynx (Figure 46-2). As air enters the nasal cavity, it is cleaned by the cilia, warmed by capillary blood vessels, and moistened by mucous membranes. The paranasal sinuses, hollow cavities that also are lined with mucous cells and cilia, open into the nasal cavity and help warm and moisten inhaled air. The filtered, warmed, and moistened air moves past the tonsils, which have an immunity function and help defend the body from potential pathogens, and through the pharynx. As the air continues toward the lungs, it passes through the larynx. The opening into the larynx is protected by a moveable piece of cartilage, the epiglottis. The larynx, or voice box, is made up of vocal cords, which vibrate when air is exhaled, creating the sound of the voice. Once the air passes through the larynx, it enters the lower respiratory tract.
The answer 1: The pleurisy
Pleurisy corresponds to the presence of liquid between the two sheets of the pleura, the membrane lining the thoracic cavity and having for goal the protection of the lungs. We speak of purulent pleurisy when the fluid contained in this pleural cavity consists of pus.
Answer 2: Pulmonary auscultation
In healthy subjects, pulmonary auscultation can be used to hear normal breathing sounds called vesicular murmur. It results from the movement of air in the tracheobronchial tree and alveoli. He is gentle, breathing in inspiration; it is more intense but shorter in expiration. There may be variations in vesicular murmur intensity as a function of chest wall thickness (eg decreased vesicular murmur in obese subjects).
In the pathological state, several abnormalities can be found at auscultation:
Inversion of the respiratory rhythm with prolongation of expiratory time (emphysema and asthma)
Changes in the vesicular murmur:
Added noises like rales, and pleural friction.
Answer 3:
The auscultation of the lungs will find suspicious signs, showing the presence of fluid in the pleura: sounds heard on normal auscultation are reduced or inexistent, and it is only in one lung generally. The confirmation is simple enough to perform via a chest x-ray showing the presence of fluid in the pleura.
Besides that, the doctor will look at the location of the pain, and he will look for breathlessness too.
