Respiratory System Essay

Breathing is an automatic process that takes place in the respiratory system. Air enters and exits the respiratory structures through the process inhalation and exhalation. Air moves in and out of the lungs as a result of changes in pressure. Inhalation is achieved when the pressure inside the lungs is less than the pressure outside of the lungs. The diaphragm contracts pulling air into the lungs. When the pressure inside the lungs is less than the pressure outside the lungs, exhalation occurs allowing

trying to breathe, the epiglottis opens up and this will allow air to pass into our respiratory tract. Now whenever food does get into our respiratory tract, sometimes if we're eating too fast and we're not giving ourselves time to swallow, then food can get lodged down in the larynx or trachea and what happens usually is we begin to cough. Coughing is basically just pushing a big puff of air through the respiratory tract, which will hopefully pop out or dislodge that food particle. This is the

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

The respiratory system is the series of organs whose primary job is taking in oxygen and putting out carbon dioxide. The respiratory system consists of three major parts: the airway, the lungs, and the muscles of respiration. The cells of the human body require a stream of constant oxygen to stay alive. The respiratory system is what provides our cells with the essential oxygen we need to live. The respiratory system is an crucial part of our anatomy that we could not live without. One of the major

I have chosen the respiratory system as my body system. It removes the carbon dioxide from the body whilst providing the body with the oxygen that it needs. There are 5 main key processes that the respiratory system control. They are: Breathing - moving air through the nasal cavity to the lungs and back out. It is also called ventilation. External respiration - gases within the air and in the blood exchange between each other. Gas transport by blood - the cells of the body receive oxygen and

2 The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of this system are the lungs, which carry out the exchange of gases as we breathe. The organs that make up the respiratory system are as followed; the nasal cavity and mouth which allows the passing of air, pharynx also known as the throat is cone shape passageway leading to the trachea. Trachea knowns as the windpipe, is the main tube connecting the nose and

Respiratory system The main structural components of the respiratory system consists of the nasal cavity and the pharynx then lower in the body there is the larynx, trachea and the lungs when you move lower into the body there is the bronchi and the bronchioles, then at the bottom of the body there is the alveoli and the diaphragm. Nasal Cavity- Is a hollow space in the nose and skull that has lots of mucus on the membrane. The function of the nasal cavity is to warm, moisturise and filter the air

Describe the Human Respiratory System Question 1: Complete the table below by describing the structure and function of each part of the respiratory system listed. Structure Function Nose The nasal root is the top of the nose, forming an indentation at the suture where the nasal bones meet the frontal bone. The nose filters air with hairs and mucus, and moisturises and warms the air. Pharynx The pharynx (throat) is a mucosa-lined, muscular tube with three regions nasopharynx, oropharynx

The Respiratory System A Review of the System, Its Components, and Diseases That Can Affect It What is the respiratory system? Why do we need to breathe? Can the process be changed or altered? The information in this paper will help you find out how the respiratory system works, what the components are that make the system work, and the many diseases that can change or alter the process. The respiratory system is made up of the organs and tissues in your body that help you breathe. The goal of breathing

The Respiratory System; including Thermoregulation, Homeostasis, Balance and Gas Exchange. INTRODUCTION The Respiratory system is made up of two parts ; 1. The Upper Respiratory System ; • Nose • Pharynx 2. The lower Respiratory System ; • Larynx • Trachea • Bronchi • Lungs. FUNCTIONS OF THE RESPIRATORY SYSTEM • Intake
