It ensures that oxygen is delivered to the bloodstream for distribution throughout the body and expels carbon dioxide, a waste product of metabolism, from the body. The respiratory system is the organs and other body parts involved in breathing when you exchange oxygen and carbon dioxide. As they take in oxygen, they release carbon dioxide, a "waste gas." It goes into your bloodstream and gets carried to your lungs.  PARTS AND FUNCTIONS NOSE  NOSE It is the main gateway of the respiratory system. Serves the sense of smell, conditions the air by filtering, warming, and moistening it, and cleans itself of foreign debris extracted from inhalations. Called External nares. Divided into 2 haves by the nasal septum. Contains the paranasal sinuses where air is warmed. The primary function of the nose is to filter, warm, and humidify the air we breathe, while also playing a key role in the sense of smell. Internal nares - Also known as the “choanae” is the opening exterior. Air exits the nasal cavities via the internal nares and moves into the pharynx. External nares- Also known as “external nostrils” is the opening to the pharynx. It allows the air to enter the nose and pass into the nasal cavity. Nasal conchae - Also known as “nasal turbinates” folds in the mucous membrane that increase air turbulence and ensure that most air contacts the mucous membranes PHARYNX  PHARYNX Pharynx is the common opening for both food that we swallow and air that we inhale/exhale. It eventually leads to the trachea or windpipe. Commonly space is used by both the respiratory and digestive systems. The primary function of the pharynx is to act as a conduit for air and food, allowing for both breathing and swallowing. 3 Section of Pharynx Nasopharynx- contains the pharyngeal tonsils (adenoids) which aid in the body's immune defense. Oropharynx- back portion of the mouth that contains the palatine tonsils which aid in the body's immune defense. Laryngopharynx- bottom section of the pharynx which the respiratory tract divides into the esophagus and the larynx LARYNX  LARYNX Larynx also known as “voice box” is composed of the vocal cords that vibrate and produce sounds as air passes through. The area of the throat is used for breathing, swallowing, and talking. The voice box is a short, somewhat cylindrical airway that ends in the trachea. The primary function of the larynx is for talking, shouting and making any other vocal sounds because it contains vocal cords, which creates sound. TRACHEA  TRACHEA Trachea is a tubular structure that connects the larynx to the bronchi, allowing air to pass in and out of the lungs. It is composed of several rings of cartilage. A flexible tube is called windpipe. The primary function of the trachea is to transport oxygen efficiently in and out of the lungs. BRONCHI  BRONCHI Bronchi are large tubes that connect to your trachea and direct the air you breathe to your right and left lungs. There are two types of bronchi (right main bronchus and left main bronchus). The primary function of the bronchi is to deliver air from the trachea into the lungs for gas exchange. BRONCHIOLES  BRONCHIOLES Bronchioles are the small, branching airways in the lungs that lead from the bronchi to the alveoli, where gas exchange occurs. Inside the lungs, the primary bronchi subdivide further, forming the bronchial tree until the smallest subdivisions called bronchioles form. At the tip of each bronchiole is an air sac. The primary function of the bronchioles is to to carry air deep into the lungs, facilitating gas exchange. ALVEOLI  ALVEOLI Alveoli are tiny, sac-like structures in the lungs where the exchange of oxygen and carbon dioxide occurs between the air and the blood. Each alveolus is one cell thick and surrounded by blood vessels (venules, capillaries, and arterioles). The primary function of the alveoli is to exchange oxygen and carbon dioxide with the blood. LUNGS  LUNGS Covered with a two-layered membrane called the hilum. Each lung has a conical shape. The lungs are two vital organs in the chest that enable breathing by absorbing oxygen from the air and expelling carbon dioxide. They are cone-shaped organs for respiration. Its wide concave base rests upon the muscular diaphragm. The process of gas exchange called respiration. The primary function of the lungs is to make oxygen available to the body and remove other gases. Left lung- divided into 2 lobes by oblique fissure. Consists of the left upper (LUL) and lower (LLL) lobes. Right lung- divided into 3 lobes by oblique and horizontal fissure. Comprised of the right upper (RUL), middle (RML), and lower (RLL) lobes. DIAPHRAGM  DIAPHRAGM Diaphragm is a sheet of smooth muscle located below the lungs. It works with the lungs during the breathing process. The primary function of the diaphragm is to contract and relax to facilitate breathing, helping to draw air into the lungs and push it out.  Taking care of our respiratory system is crucial for overall health and well-being. That is why we should avoid harmful environmental factors such as smoke, dust, and chemicals. 1. Avoid Smoking and Pollutants: Smoking is one of the leading causes of respiratory issues. Avoid smoking and exposure to secondhand smoke. HOW TO TAKE 2. Exercise Regularly: Physical activity helps improve lung function and respiratory health. Aim for at least 30 minutes of moderate exercise most days of CARE OF OUR the week. 3. Maintain a healthy diet and stay hydrated: Your body uses food as a fuel and the process of changing food into energy with the help of oxygen (or metabolism) RESPIRATORY is only accomplished with the help of your lungs. 4. Get annual check-ups: Visiting your healthcare provider regularly for a check- SYSTEM up helps prevent illness, so keep those medical appointments even when you are feeling well. 5. Stay up to date with vaccinations: Infectious respiratory diseases such as influenza, COVID-19, and RSV spread from person to person, the best way to stop the spread is through being vaccinated. Vaccinations can protect against respiratory infections.  SUMMARY In summary, the respiratory system is essential for life, facilitating the exchange of oxygen and carbon dioxide. Its components work together to support breathing and maintaining health. Understanding how it functions helps us appreciate its importance and recognize the impact of respiratory issues.  You can now..
