The respiratory system by sarah
The respiratory system takes oxygen into the body through the airways and lungs, and releases carbon dioxide out. It includes passages connecting the nose, mouth, and lungs. The lungs are located in the chest and are protected by ribs. Inside the lungs are alveoli, bronchi, and bronchioles. The nose, mouth, and trachea take air in and out, while the diaphragm is the main breathing muscle that contracts on inspiration and relaxes on expiration.

Respiratory s.
The respiratory system allows humans to breathe by bringing oxygen into the body and removing carbon dioxide. When we breathe in, air travels through the windpipe into the lungs where tiny air sacs called alveoli exchange oxygen and carbon dioxide with blood vessels. The oxygenated blood is then circulated throughout the body while the carbon dioxide is breathed back out. Breathing and heart rate both increase during exercise to supply cells with more oxygen as they work harder and produce more waste.
The Respiratory System
The respiratory system allows us to breathe and contains six main parts: the larynx, trachea, bronchi, bronchioles, lungs, and diaphragm. The larynx contains vocal cords that allow us to talk using air. The trachea is a tube that conveys air from the larynx to the bronchi and splits into the right and left primary bronchi. The lungs are large organs that hold the air we breathe and contain small air sacs called alveoli where oxygen and carbon dioxide are exchanged. The diaphragm is a muscle that separates the chest from the abdomen and helps with inhalation and exhalation.

Science (1. Respiratory System and Circulatory System Working With The Other ...
The respiratory system involves air entering the nose and traveling through the trachea, which divides into two branches called bronchi. The bronchi subdivide many times inside the lungs, forming hairlike tubes called bronchioles. At the end of the bronchioles are tiny bubble-like structures called alveoli. When breathing in, the diaphragm contracts, and when breathing out, it relaxes to help air in and out of the lungs. The circulatory system involves blood traveling from the heart through the bloodstream to cells, where oxygen is used and carbon dioxide is released as waste, before blood returns to the heart and lungs to release carbon dioxide. The heart is a hollow muscular organ divided into four chambers -
The respiratory system
The document describes the key components of the respiratory system and how they work together to supply oxygen to the body. It explains that the respiratory system includes the larynx, trachea, bronchi, bronchioles, lungs, diaphragm, and alveoli. The trachea divides into bronchi that branch into bronchioles and end in alveoli in the lungs. The alveoli absorb oxygen from the air inhaled through the mouth and nose and transfer it to blood vessels to be carried through the body.
Respiratory system[1]
The respiratory system performs three important functions for the air we breathe: warming it, moistening it, and filtering it. It is made up of the nasal passage, pharynx, epiglottis, larynx, trachea, bronchi, bronchioles, and alveoli. The lungs contain no muscle tissue, so breathing is driven by the diaphragm and intercostal muscles increasing and decreasing the space in the chest cavity. Cellular respiration uses oxygen to extract energy from foods through the breakdown of glucose.
1.2.3 Lesson 1 - The respiratory system
1) The respiratory system works by inhaling air through the nose and mouth into the lungs. During inhalation, the diaphragm and intercostal muscles contract to expand the lungs and decrease pressure, allowing air to rush in.
2) Gas exchange occurs in the alveoli where oxygen passes into the blood and carbon dioxide passes out of the blood. The air then exits during exhalation through the same process in reverse.
3) Tidal volume and vital capacity can be measured using a spirometer or peak flow meter. Tidal volume is the amount of air inhaled and exhaled during normal breathing, while vital capacity is the maximum amount of air that can be inhaled and

The document provides an overview of the respiratory system including what it includes, how it works, why we need it, common diseases and illnesses, and ways to protect the respiratory system. The respiratory system includes the lungs, airways, diaphragm, windpipe, throat, mouth, and nasal passages. It works by bringing air into the lungs through the nose and mouth, distributing it through the bronchi and into the blood, and then removing carbon dioxide through exhalation. We need the respiratory system to provide oxygen to all our cells. Common respiratory illnesses include asthma and chronic obstructive pulmonary disease. Ways to protect the respiratory system include not smoking, avoiding air pollution, and regular exercise.

The document provides information about the human respiratory system through various activities and exercises. It begins with identifying key parts of the respiratory system like the eyes, kidneys, and lungs. Students then participate in a "bottled balloons" activity to model breathing and label parts like the trachea, bronchi, and diaphragm. The document continues with diagrams, analogies and sequencing charts to illustrate how air moves through the nasal passage, lungs, and other respiratory organs before exiting as carbon dioxide. Key terms are defined and fun facts about breathing and lung capacity are also included.
Group 5
The document summarizes the key components and functions of the respiratory system. It describes how air travels through the nose or mouth into the trachea, which then branches into the bronchi and bronchioles leading to the alveoli in the lungs. The alveoli are where gas exchange occurs, as oxygen passes into the bloodstream while carbon dioxide is removed. Breathing is controlled by the respiratory center in the brain and muscles like the diaphragm and ribs. Disruption of the respiratory system for more than a few minutes can cause tissue damage and ultimately death if normal breathing is not restored.
Physical education human respiration
The document discusses the human respiratory system. It describes the key parts and their functions, divided into the upper and lower respiratory tracts. The upper tract includes the mouth, nose, nasal cavity and pharynx. The lower tract includes the trachea, bronchi, bronchioles and diaphragm. It emphasizes the importance of warming up before exercise to allow the lungs to function at an appropriate pace and avoid tiring out prematurely. Proper introduction and training in exercises from warm up to completion is recommended for physical education.
Bottled balloons- group 1
The document describes how lungs work with the help of the diaphragm muscle. It explains that inhaling occurs when the diaphragm contracts, pulling down and expanding the chest cavity so that air is drawn into the lungs. Exhaling happens when the diaphragm relaxes and the chest cavity decreases in size, pushing the air out of the lungs. The diaphragm is essential to breathing by controlling the movement of air in and out of the lungs.
The respiratory system
The respiratory system is vital for breathing and consists of important parts like the trachea, bronchi, lungs, bronchioles, and alveoli. The trachea connects the larynx to the lungs and allows breathing. The bronchi branch off the trachea to deliver air to the lungs. The lungs hold air and facilitate gas exchange in the alveoli. The bronchioles and alveoli are responsible for controlling airflow and transferring oxygen and carbon dioxide between the blood and air. The diaphragm helps breathing by expanding and contracting the lungs.
Bottled balloons -group5
This document describes a model of the respiratory system using balloons and straws. The plastic bottle represents the chest cavity, straws represent bronchi, small balloons represent lungs, and large balloons/cellophane represent the diaphragm. Pulling down the diaphragm balloon causes the lung balloons to expand, representing inhalation. Pushing up the diaphragm balloon causes the lung balloons to contract, representing exhalation. The diaphragm controls air moving in and out of the lungs by changing the chest cavity size and pressure.
human eye class - X
The respiratory system allows for oxygen to enter the body and carbon dioxide to be released. It consists of the nose, pharynx, larynx, windpipe, bronchi, bronchioles, and lungs. When breathing in, air enters the nose and is warmed and filtered before passing through the pharynx and larynx into the windpipe. The windpipe divides into bronchi that branch into smaller bronchioles and end in tiny air sacs called alveoli where oxygen passes into the blood and carbon dioxide leaves the blood to be breathed out.
Asthma Information
Asthma is a chronic lung disease that causes airways to narrow and become inflamed, resulting in recurring periods of wheezing, chest tightness, shortness of breath, and coughing. When the airways become inflamed, the muscles around them tighten causing less air to flow into the lungs. Sometimes symptoms are mild but other times an asthma attack occurs where symptoms intensify or additional symptoms develop. Proper management is needed as there is currently no cure for asthma, but most people can live normal, active lives with today's treatments.
The respiratory system
The respiratory system brings oxygen into the body and removes carbon dioxide. It works through the process of breathing, where oxygen is inhaled through the nose and mouth into the lungs and carbon dioxide is exhaled. In the lungs, oxygen passes into tiny sacs called alveoli and enters the bloodstream, while carbon dioxide moves from the blood into the alveoli and is then exhaled. The diaphragm helps with breathing by contracting to pull oxygen into the lungs and relaxing to push carbon dioxide out. Common respiratory diseases include asthma, bronchitis, COPD, pneumonia and lung cancer.
The respiratory system
The respiratory system allows us to breathe by taking in oxygen and expelling carbon dioxide. The lungs and nose or mouth are used to inhale air which travels through the trachea into the lungs. When we breathe in, the diaphragm contracts pulling air into the lungs, and when breathing out it relaxes pushing air out. Oxygen passes from the lungs into the blood while carbon dioxide passes from the blood to the lungs.

This document describes procedures for static and dynamic balancing of rotating masses. Static balancing involves determining the position and magnitude of balancing masses to balance a system. It is done by adding masses to balancing pans until a pointer rotates 90 degrees, noting the mass needed. Dynamic balancing also determines mass positions, but accounts for motion by drawing force and couple polygons to calculate linear positions of masses along the shaft. Both methods aim to balance rotating systems to prevent premature failure and vibrations.

The respiratory system
The respiratory system is responsible for breathing and gas exchange. It includes the nose, sinuses, mouth, larynx, epiglottis, trachea, lungs, diaphragm and alveoli. The nose and sinuses warm, clean and humidify inhaled air using hairs called cilia and mucus. Air then travels through the trachea to the lungs where oxygen and carbon dioxide are exchanged in alveoli before being transported by red blood cells. The diaphragm and rib muscles help breathing by expanding the lungs. Coughing, sneezing and yawning help clear the respiratory tract. Diseases like pneumonia, bronchitis and lung cancer can affect the lungs.

The respiratory system consists of the airways, lungs, and respiratory muscles that work together to oxygenate the body and remove carbon dioxide. It has two main functions: bringing oxygen into the body and removing carbon dioxide and water. The nose warms and filters air before it reaches the lungs. The pharynx connects the nose and mouth to the esophagus and helps swallow food and breathe. The larynx contains vocal cords and produces sounds when speaking or singing. The diaphragm contracts and expands the lungs to breathe in and out without conscious effort.

The document provides information about the respiratory system. It describes the purpose of the respiratory system as taking in oxygen and removing carbon dioxide. It then discusses the lungs and trachea in more detail, describing their functions and diagrams of their structures. It also includes sections on lung cancer symptoms, treatment, and prevention.
The respiratory system SSA+S
The respiratory system takes in oxygen and removes carbon dioxide through a series of major organs including the lungs, bronchi, trachea, larynx, pharynx, mouth and nose. It interacts with the circulatory system to exchange gases and the nervous system to control breathing rate. The system works to maintain homeostasis by supplying oxygen to the body and removing carbon dioxide through breathing and the complex exchange of gases within the lungs and bloodstream.

The respiratory system is made up of organs that help the body breathe by delivering oxygen and removing carbon dioxide. It includes the nasal passages, mouth, pharynx, trachea, bronchi, bronchioles and lungs. The lungs receive oxygen and remove carbon dioxide as it travels through the bloodstream to cells throughout the body. Diseases like asthma and restrictive lung disease can affect the respiratory system. We need the respiratory system to breathe and provide oxygen to cells in order for the body to function.

Vital signs - Respiration
This document discusses respiration and the process of breathing. It defines respiration as the exchange of oxygen and carbon dioxide between the lungs and blood, and between blood and tissues. It describes the mechanics of breathing including inhalation driven by contraction of the diaphragm and intercostal muscles, and exhalation via relaxation of these muscles and elastic recoil of the lungs. Factors that can affect respiratory rate such as temperature, medications, and disease states are also summarized.
Respiratory system
The respiratory system allows us to breathe in oxygen and breathe out carbon dioxide. It consists of major organs like the lungs, pharynx, larynx, trachea, bronchi, and alveoli. The respiratory system interacts with other systems like the muscular system which helps push air in and out of the lungs. It also works with the circulatory system to intake oxygen and remove carbon dioxide to maintain homeostasis. Common respiratory illnesses include colds and lung cancer from smoking, so keeping away from irritants and pollution is important for respiratory health.
Respiratory system
The document describes the process of respiration and the structures involved in gas exchange in the human respiratory system. It explains that oxygen is absorbed into the blood and carbon dioxide is released from the blood in alveoli, tiny air sacs found in the lungs. A series of tubes called the windpipe and bronchi transport air to and from the lungs, where gas exchange with blood takes place across the thin membranes of the alveoli.

Respiratory2
- 1. The Human Respiratory System By Gene and Kevin
- 2. Introduction to the Human Respiratory System The Respiratory System is what controls breathing. It brings in the oxygen your body needs and gets rid of the carbon dioxide that is left over. If you didn’t breathe you would pass out or die.
- 3. How the Human Respiratory System Works The Respiratory System helps you breathe. When the human body breathes air, it gets sucked through the nostrils or the mouth. Then it goes through the trachea (wind pipe). The trachea divides into tubes called bronchi which carry the air on to each lung.
- 4. Some More Ways the Human Respiratory System Works The diaphragm pulled the oxygen down to the bronchi and into the lungs. Then, it goes into a million moist air sacks which expand and contract like a sponge with water.
- 5. Caring for Your Respiratory System You should take care of your Respiratory System because if you don’t you won’t be able to breathe. Using drugs can keep your brain from telling your lungs to breathe. Smoking can make your lungs turn black and not work well.Breathing clean air is healthiest for you. Exercise keeps your lungs strong.
- 6. Amazing Facts About the Respiratory System Did you know that... • Your right lung has three lobes and your left lung only has two? • The right lung is a little larger than the left lung? • A person sleeping almost always breathes twelve or fifteen times a minute?
