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.

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

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 The human respiratory system plays a very important part in our bodies. Without it‚ we wouldn’t be alive! We need air to move through our bodies at all times. Breathing‚ is a key necessity for life. Our respiratory system is made up of many organs that all work together. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide. The respiratory system organs all work together‚ like a engine in a car‚ they all have a important role. Some

Source google Respiratory System Lung Model Grade: 5th Rational: Students can’t look inside their chest and observe how their lungs work. After making a working model of the respiratory system students can connect what they read about the respiratory system with what they see. Prior Knowledge: Students have read aloud a respiratory system chapter from their science book‚ "Discovery Works" in class. Students should know the parts of the respiratory system and the basics of how it operates

RESPIRATORY SYSTEM The respiratory system consists of all the organs involved in breathing. These include the nose‚ pharynx‚ larynx‚ trachea‚ bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies‚ which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide‚ which is a waste product of cellular function. The nose‚ pharynx‚ larynx‚ trachea and bronchi all work like a system of pipes through which

Anatomy of the Respiratory System Nose and Nasal Cavity The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway—the respiratory tract through which air moves. The nose is a structure of the face made of cartilage‚ bone‚ muscle‚ and skin that supports and protects the anterior portion of the nasal cavity. The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The function

The human respiratory system is one of the chief and most important which is very instrumental for survival. Prime function of the respiratory system is breathing. Inhaling oxygen and exhaling carbon dioxide is all that takes plays by function of the respiratory organs. Breathing is a process by which oxygen in the air is brought in to the lungs and further in to close contact with blood. The blood absorbs the oxygen and carries to all parts of the body. Simultaneously blood gives up waste matter

The respiratory system The respiratory system is responsible for providing oxygen and removing carbon dioxide‚ heat and water vapours. All living creatures require oxygen and give off carbon dioxide. Oxygen is required for every cell in your body to function. Structure of the respiratory system: Normally air is taken in through your nose however sometimes it is taken in through your mouth and passes through a series of airways to reach the lungs. This series of airways is known as the respiratory
