Respiratory DiseaseLeslie ThompsonHCS/245September 22‚ 2014Sheela AlvaradoRespiratory DiseaseThe respiratory system involves breathing and the exchange of gases. It supplies oxygen to vital cells to live and function correctly. It also helps get rid of carbon dioxide‚ which is a product of cellular waste. The respiratory system is divided into two parts the upper respiratory system includes the nose‚ sinuses‚ larynx‚ pharynx‚ and mouth. The lower respiratory system which make up the lungs includes

Answers 1a) On graph paper 1b) At molecular level‚ Haemoglobin is a protein made of four subunits bound together. Each of the subunits consists of a molecular group known as ‘heme’ and a polypeptide attached to the ‘heme’. The ‘heme’ group contains one atom of iron (Fe²+) and it is this iron that the oxygen molecule combines itself to. As there are four of the iron molecules in the haemoglobin this shows that a maximum of four oxygen molecules can be carried by the haemoglobin at anytime. For simplicity

Neonatal respiratory failure affects 2% of all live births‚ and is responsible for over 40% of all neonatal mortality. Persistent pulmonary hypertension of a new born (PPHN) is a life threatening disease with many causes that effects both full term‚ near term infants usually in the first 72 hours after birth. Although most infants recover‚ PPHN causes a severe problem in the infant’s lungs due to high blood pressure. About 500-700 babies are affected by PPHN each year. A better understanding of

The importance of the Respiratory system is quite obvious given that as human beings we need this system to help us with our most fatal tasks of breathing. Although the importance is assumed and acknowledged‚ many do not really get the whole concept of the Respiratory system. For example‚ how it works? Why it works? And what all is involved. These questions and others will be strategically answered in the following work. The Respiratory System delivers oxygen to the body and takes the carbon

Respiratory System WebQuest Introduction The primary function of the respiratory system is to supply the blood with oxygen. The respiratory system does this through breathing. Breathing is a natural process that we use to obtain oxygen‚ unlike eating or drinking to get energy. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The respiratory tract is responsible for taking the gases

The respiratory system provides life giving oxygen to cells through inspiration of air; at the same time‚ it removes carbon dioxide waste from cells through expiration‚ which can be lethal if not ventilated properly. This process is called pulmonary ventilation and is facilitated by three major components of the respiratory system: airways‚ lungs‚ and muscles; all of which play a vital role in the respiratory cycle and homeostasis. The respiratory cycle begins in the airways and during inhalation

Respiratory System Respiration: The primary function of the respiratory system is to obtain oxygen gas for cell metabolism and remove carbon dioxide waste. Describe each of the following general processes of respiration. Ventilation- air is moved into and out of the lungs so the gases there are continuously changed and refreshed external respiration- oxygen diffuses from the lungs to the blood‚ and carbon dioxide diffuses from the blood to the lungs gas transport- oxygen is transported

The respiratory system is composed of the nasal cavity‚ nostril‚ oral cavity‚ pharynx‚ larynx‚ trachea‚ carina of trachea‚ right main bronchus‚ right lung‚ left main bronchus‚ left lung‚ and diaphragm. These major organs collectively work together to give the body oxygen and eliminate carbon dioxide as we breathe. In order for the respiratory system to be fully capable of function‚ four procedures (pulmonary ventilation‚ external respiration‚ transport of respiratory gases‚ internal respiration)
