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

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

Research Paper The Respiratory System As humans‚ our body is made out of different systems‚ which work together to make us live day by day. One major system is the respiratory system. The respiratory system includes the nose (the nasal cavity and paranasal sinuses)‚ pharynx (throat)‚ larynx (voice box)‚ trachea (windpipe)‚ bronchi‚ and the lungs. The respiratory system begins from our respiratory tracts that carry air to and from the exchange surfaces of the lungs. Respiratory tract can be divided

PhysioEx 9.0 Exercise 3 Neurophysiology of Nerve Impulses A C T I V I T Y 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. Increasing the extracellular potassium reduces the concentration gradient‚ and less potassium diffuses out of the neuron and into the cell. 2. Explain why increasing extracellular K_ causes the membrane potential to change to a less negative value.

Aguilar Prof. Ivan Marcelo Duka G-7L BIO 2 RESPIRATORY SYSTEM The Respiratory system consists of organs and tissues that aid the oxygen to travel in the body and emits the waste gases out of the body. It is also called as the oxygen delivery system for it is the system responsible in delivering the oxygen to all parts of the body. The process of breathing‚ the inhalation of oxygen and exhalation of carbon dioxide‚ is called respiration. Respiration can be described

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

The respiratory system is an intricate network of organs all working together to insure a constant flow of gases‚ oxygen and carbon dioxide‚ to keep the body functioning at rest or during exertion’ (ehow). The respiratory system is made up of the nose‚ trachea‚ bronchi‚ diaphragm and lungs. The aim of this assignment is to look at the structure and functions of the respiratory system and also provide an illustration of the respiratory system.. The lungs are an integral part of the human body‚
