Process of Respiration in Humans â Diagram The process of respiration involves four stages – ventilation which we know as breathing (inhalation or inspiration and exhalation or expiration), exchange of gases between the air in the lungs and blood stream (pulmonary diffusion), transport of gases in the blood (perfusion) and exchange of gases between the blood and tissues (peripheral diffusion ...

What causes difficulty swallowing (dysphagia)? Dysphagia is a difficulty swallowing and can be caused by a number of factors. A typical swallow involves several different muscles and nerves; it is a complex process: Seeing, smelling, and tasting - when we see, smell, or taste food or drink we produce saliva, which is designed to make chewing easier.

Understanding the Stages of Labor The stages of labor are commonly broken down into three main phases. This is misleading, however, in that the first stage is comprised of three sub-phases and is what most people identify as labor. Stage I consists of early labor, active labor and transition. Stage II is the pushing stage and Stage III is the birth of the placenta.

Post-Nasal Drip With age, swallowing muscles often lose strength and coordination, making it difficult for even normal secretions to pass smoothly into the stomach. 1  During sleep, swallowing occurs much less frequently, and secretions may gather. Coughing and vigorous throat clearing are often needed upon waking.

Mechanics of Respiration The gaseous exchange phase of respiration consists of two phases: Inspiration and Expiration. These are accomplished by the alternate increase and decrease of the capacity of the thoracic cavity. The normal rate of respiration for a healthy adult individual is 16 to 20 breaths per minute.he gaseous exchange phase of respiration consists of two phases: Inspiration and Expiration.

How long does it take for food to go from your mouth to your stomach? In this article. Swallowing is a very complex act, requiring the normal function of the brain, several nerves and muscles, two muscular valves, and an open, unconstricted esophagus, or swallowing tube. The swallowing tract extends from the mouth to the stomach. The act of swallowing normally occurs in three phases. In the first phase, food or liquid is contained in the mouth by the tongue and palate (oral cavity). This phase is the only one we can control.

Stages of a Swallow Stages of a Swallow. Eating and drinking belong to the basic necessities of mankind. A healthy adult swallows between 800 and 2400 times a day (1). Although swallowing seems easy, in reality it requires an extremely complicated interaction between various muscles.

Cortical & Subcortical Regions involved in the Swallowing Process The brainstem areas involved in control of swallowing are located in the dorsal region within and subjacent to the nucleus of the tracts solitarius as well as in the ventral region around the nucleus ambiguus. The neurons in the brainstem surrounding the adjacent medullary reticular formation are also involved.

Dysphagia Pharyngeal stage – The tongue pushes the food or liquid to the back of the mouth, triggering a swallowing reflex that pushes the food into the pharynx (throat). The voice box (larynx) closes tightly and breathing stops to prevent food or liquid from entering into the lungs.

Mitosis - When Cells Split Apart Beyond the idea that two identical cells are created, there are certain steps in the process. There are five (5) basic phases in the life-cycle of a cell. You should remember the term PMATI (pronounced PeeMahtEee). PMATI is the acronym for the phases of a cell's existence.

Ternary phase diagrams Ternary phase diagrams. Phase diagrams are graphical representations of the liquid, vapor, and solid phases that co-exist at various ranges of temperature and pressure within a reservoir. Ternary phase diagrams represent the phase behavior of mixtures containing three components in a triangular diagram.

Pediatric Swallow Studies Pediatric swallow studies are completed by highly trained Speech Language Pathologists using state-of-the-art dynamic, digital x-rays of the process of swallowing. The study defines the nature of a child's swallowing disorder and identifies adaptations to facilitate improved swallowing. Complications such as silent aspiration, food/liquid residue and reflux can be visualized and analyzed for the influence of bolus size and food consistency. A comprehensive evaluation includes clinical and instrumental examination of swallowing function, and is followed by recommendations for an individualized swallowing therapy program.

Stages of deglutition The process of swallowing is known as deglutition. The act of swallowing can be divided into three stages for easy understanding. 1. Oral stage: This is the only voluntary stage in the act of swallowing. It consists of: Mastication of food making it into a bolus fit to be swallowed. The main muscles involved in the act of chewing are: a. Masseter.

Evaluation and Treatment of Swallowing Impairments Swallowing disorders are common, especially in the elderly, and may cause dehydration, weight loss, aspiration pneumonia and airway obstruction. These disorders may affect the oral preparatory, oral propulsive, pharyngeal and/or esophageal phases of swallowing.

- Aspiration is a generic term refering to the action of material penetrating the larynx and entering the airway below the true vocal folds. Purpose of swallowing evaluation is to define the reason for the presence of aspiration. Aspiration may occur under several circumstances. 1  Before the swallowing reflex is triggered, when the airway has not elevated or closed. 2  During the swallowing if the laryngeal valves are not functioning adequately. 3  After the swallow when the larynx lowers and opens for inhalation.

- Other chronic motor neuron disorders such as spinal muscular atrophy sometimes affect the muscles of swallowing, except in the infantile variant (type 1) known as Werdnig-Hoffman disease. These children are often born hypotonic and floppy with weak suck and limb motion. Most children die in the first 3 years of life.

Stages of Swallowing (5) neuromuscular components of swallowing. 1)Lip closure to hold the bolus in the mouth anteriorly (keeps food from spilling) 2)Tension in the labial and buccal musculature to close the anterior and lateral sulci. 3)Rotary jaw (circular) motion for mastication/grinding.
