What is the function of the nasal cavity? Warms‚ moistens‚ and filters the incoming air. 7. What does mucous do? Provide lubrication and prevent infection 8. What is the function of the larynx? Across the larynx are 2 tiny ridges called vocal cords. As air flows in

Anatomy and Physiology of Respiratory System Overview Cells in the body require oxygen to survive. Vital functions of the body are carried out as the body is continuously supplied with oxygen. Without the respiratory system exchange of gases in the alveoli will not be made possible and systemic distribution of oxygen will not be made possible. Thetransportation of oxygen in the different parts of the body is accomplished by the blood of the cardiovascular system. However‚ it is the respiratory

live and speak‚ we must be able to breathe. Respiration is the act of breathing. The act of drawing in a breath‚ or inspiration is the process of in-taking air. Air is taken in through the upper airways‚ which includes the nasal cavity‚ pharynx and larynx. The air then passes through the lower airways‚ which includes the trachea‚ primary bronchi and bronchial tree. The air then goes through the small bronchioles and alveoli within the lung tissue

the lung the bronchi split several ways‚ forming tertiary bronchi. Bronchioles - The main function of the bronchioles is to carry air from the trachea into the lungs. When someone takes a breath through their nose or mouth‚ the air travels into the larynx. The next step is through the trachea‚ which carries the air to the left and right bronchus. The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. Alveoli - Alveoli are tiny sacs within our lungs that

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 into a conducting portion and a respiratory

My journey when a seventh grade student inhales Others molecules of oxygen have ask me to tell my journey when a seventh grade student inhales. I would always say: “Try it yourself‚” but now that I’m older and lazy and dying‚ I’m tired to say those same words over and over and over again. So I decided to write it out. Here is my own journey in a seventh grade student that inhales that you will never experience again. It all started when a seventh grade student inhaled deeply in a Science Classroom

So today kids we will be going on a “fantastic voyage” thru the body of a healthy female. We will first need to find a guide that can get us from the right femoral vein to the lower lobe of the right lung and then to exit out of the nose. The reason for this is because we were just informed that the female’s body was invaded by a bacterium‚ which is invading the right lung and this is our only hope of getting out of her body. Before we can start our journey I would like you to meet Mr. Windzel‚ he

organs that are located in the upper respiratory tract are the nose‚ nasal cavity‚ paranasal sinuses‚ and pharynx. 5. What organs are in the lower respiratory tract? The organs that are located in the lower respiratory tract are the larynx‚ trachea‚ bronchial tree‚ and lungs. 6. What is the function of the nasal cavity? The nasal cavity is where the internal hairs begin to filter air. The primary function is to conduct air to the pharynx‚ where mucous lining filters and
