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

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

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 into two processes: internal or cellular respiration

Homeostasis is defined as the adjustments a body makes to maintain an environment conducive to life. All of the organ systems in the human body must maintain a steady internal environment for the body to function properly. The factors that need to be controlled are water and salt content‚ PH balance‚ oxygen‚ sugar‚ protein‚ body temperature‚ and blood and glucose concentration. The basic principle of homeostasis is when there is an abnormal internal condition‚ it will be detected and a variation

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

Respiration. *The respiratory system consists of tubes that filter incoming air and transport it into the microscopic alveoli where gases are exchanged the entire process of exchanging gases between the atmosphere and body cells is called respiration and consists of the following: ventilation‚ gas exchange between blood and lungs‚ gas transport in the bloodstream‚ gas exchange between the blood and body cells‚ and cellular respiration *The organs of the respiratory tract can be divided into two

Maintaining a Healthy Body There are many theories and definitions to what a Healthy Body is. Health can be defined in terms of the absence of disease‚ which can be described as a negative approach to health (1). However another definition is that health are a state of complete physical‚ mental and social well-being and not merely the absence of disease (2). Each individual body is different therefore it can be difficult to perceive if they are healthy. By looking at a person you can see

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
