Exercise No. Respiratory System I. Introduction Oxygen is a very important element which our body needs. Without oxygen life is not possible without oxygen which helps in producing energies that our body cells need. But‚ how do we acquire this oxygen needed by the body? It is by the process called Respiration. Respiration is a process of taking in and out of air from the body. There are two kinds of respiration called cellular respiration and external respiration. Cellular respiration

The Respiratory System STRUCTURAL PLAN Basic plan of respiratory system would be similar to an inverted tree if it were hollow; leaves of the tree would be comparable to alveoli‚ with the microscopic sacs enclosed by networks of capillaries (Figure 14-1) Passive transport process of diffusion is responsible for the exchange of gases that occur during respiration. RESPIRATORY TRACTS Upper respiratory tract—nose‚ pharynx‚ and larynx Lower respiratory tract—trachea‚ bronchial tree‚ and lungs

The Respiratory System is crucial to every human being. Without it‚ we would cease to live outside of the womb. Let us begin by taking a look at the structure of the respiratory system and how vital it is to life. During inhalation or exhalation air is pulled towards or away from the lungs‚ by several cavities‚ tubes‚ and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the

Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

Separation techniques LIQUID CHROMATOGRAPHY ‘THE ART OF SEPARATION’ CHROMATOGRAPHY – AN INTRODUCTION Chromatography is a technique through which a mixture of chemical components are separated‚ identified and determined accurately. This technique while provides a way for analytical separations‚ also useful for preparative techniques by which pure compounds can be obtained.

Respiratory system: The respiratory system is a combination of the Circulatory and Pulmonary systems feeding oxygen and nutrients to cells all around the body. These systems allow oxygen to enter the body‚ and be circulated around the body at a varying rate. These two systems work in conjunction with each other and have various rates of operation that are usually in as close a correlation as possible. Circulatory System: The circulatory system’s primary responsibility is to circulate oxygenated

2011 Respiratory Diseases: Infections Invading the Lungs The average human takes breathing for granted. One might think that breathing is just an involuntary movement‚ but for the millions of people who suffer from respiratory illnesses‚ each and every breath is a major accomplishment to another day of daily life. The respiratory system not only oxygenates the blood for the body‚ but also filters out wastes‚ infections‚ and provides the air that is needed for daily speech. The respiratory system

The human body requires many things to function. One of the most important requirements is oxygen. Oxygen is used by the entire body to make energy. The Respiratory System collects and filters the air we breath to get that precious oxygen. The respiratory(breathing) process begins when you inhale and air is taken in through the mouth and/or nose. The air flows into the pharynx(throat) and enters the trachea(windpipe). The air then flows into one of two bronchi‚ left bronchus and right bronchus.

categories: acute and chronic.[1][2][3][4] Acute bronchitis is characterized by the development of a cough or small sensation in the back of the throat‚ with or without the production of sputum(mucus that is expectorated‚ or "coughed up"‚ from the respiratory tract). Acute bronchitis often occurs during the course of an acute viral illness such as the common cold or influenza. Viruses cause about 90% of acute bronchitis cases‚ whereas bacteria account for about 10%.[5][6] Chronic bronchitis‚ a type

Complete information on the mechanism of Respiratory System in Man NIRMALA AGARWAL Respiratory organs are those which are concerned with the passage of the air to and from the lungs. The latter are‚ of course‚ mot important of all. The passage is also called respiratory tract. For the sake of convenience‚ the respiratory tract can be divided into upper and lower parts. The upper part extends from the external nostrils (external openings of nose) to the vocal sac present in the neck. The lower part
