The upper respiratory system includes the nasal cavity, pharynx and larynx. The nasal cavity warms, cleans and humidifies inhaled air. The pharynx is a common passageway for food and air. The larynx produces sound and routes food and air to the proper passageways. The lower respiratory system includes the trachea, bronchi, bronchioles and lungs. The trachea transports air from the larynx to the primary bronchi. The bronchi branch into smaller secondary and tertiary bronchi which lead to bronchioles and alveoli in the lungs where gas exchange occurs.

Breath sounds originate from vibrations in the airways that are transmitted through the lung tissue and chest wall. Vesicular breath sounds are quiet with a short, almost silent expiratory phase, resulting from attenuation by normal lung tissue. Bronchial breath sounds are loud and high pitched with equal inspiration and expiration durations, produced by air passing through large airways in diseased, collapsed, or consolidated lung areas. There are three types of bronchial breath sounds: tubular, cavernous, and amphoric, which differ in pitch and quality and are associated with specific lung abnormalities.
Anatomy of the respiratory tract
The respiratory tract includes the mouth, nose, pharynx, larynx, trachea, bronchi and lungs. The nose contains nasal cavities lined with hairs and mucus to warm and filter air. It connects to the nasopharynx and paranasal sinuses. The pharynx consists of the nasopharynx, oropharynx and laryngopharynx and contains the tonsils. The larynx, or voice box, contains vocal cords and cartilage that support the airway and allow for sound production. It connects to the trachea and lungs.
Anatomy & mechanics of respiratory system
The respiratory system consists of upper and lower respiratory tracts. The upper tract includes the nose, nasal cavity and pharynx while the lower tract includes the larynx, trachea, bronchi and lungs. The respiratory tract transports air to the gas exchange surfaces in the lungs. It divides into a conducting portion from the nose to terminal bronchioles and a respiratory portion where gas exchange occurs in alveoli. The lungs have lobes and are made of branching bronchial tubes that terminate in alveoli where oxygen and carbon dioxide are exchanged with blood through thin epithelial walls.
Human Anatomy&Physiology Respiratory S.
The respiratory system has three main functions: gas exchange, pulmonary ventilation, and transport of respiratory gases. It has two main zones - the conducting zone which includes the nose, pharynx, larynx, trachea, and bronchi, and the respiratory zone where gas exchange occurs in the alveoli. Gas exchange takes place across the alveolar-capillary membrane, which is only one cell thick. Oxygen moves from the alveoli into the blood in the pulmonary capillaries and carbon dioxide moves out of the blood into the alveoli.

The lung buds develop around 4 weeks of gestation from the ventral wall of the foregut. They initially have an open connection to the foregut, which later separates to form the esophagus dorsally and the trachea and lung buds ventrally. Each lung bud develops into the main left and right bronchi by 5 weeks, which further branch to form the lobar bronchi. The developing lungs continue branching throughout gestation to form over 17 generations of branches by 6 months. After birth, further branching occurs to complete lung development over the first 10 years of life.

The respiratory system allows the body to breathe and exchange oxygen and carbon dioxide. It includes the nose, mouth, throat, trachea, bronchi, and lungs. The lungs obtain oxygen from inhaled air and release carbon dioxide, and the trachea and bronchi form a passageway to distribute air to and from the lungs. During breathing, the diaphragm and rib cage work to inhale air down the trachea and into the lungs' alveoli where gas exchange with blood occurs through diffusion.

Anatomy of respiratory system.
The respiratory system is responsible for gas exchange between the circulatory system and the outside world. Air enters through the nasal cavity and pharynx, then travels through the trachea and bronchi into the bronchioles and alveoli in the lungs. The lungs are divided into lobes and contain millions of alveoli which facilitate gas exchange with blood capillaries. During inhalation, intercostal muscles and the diaphragm expand the lungs to create negative pressure and draw in air. Exhalation is passive as the lungs recoil.
Respiratory Assessment & Diagnostic Findings
This document provides information on nursing management of respiratory disorders in adults and elderly patients. It discusses the anatomy and physiology of the respiratory system and assessment of respiratory issues. It then covers the etiology, pathophysiology, clinical manifestations, diagnosis, treatment and nursing management of various respiratory conditions including upper and lower respiratory tract infections, asthma, COPD, pneumonia, pulmonary embolism and others. It also mentions respiratory therapies, procedures, drugs and nursing assessments and interventions for respiratory disorders.
The respiratory system by sujeet
The document describes the human respiratory system. It includes diagrams of the major structures like the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles and lungs. It defines respiration as the process of gas exchange between oxygen and carbon dioxide in the blood and alveoli. Breathing is controlled by the medulla oblongata which monitors carbon dioxide levels and signals the diaphragm to contract and expand the lungs during inhalation. Oxygen diffuses into blood capillaries surrounding each alveolus while carbon dioxide diffuses out, allowing for gas exchange.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Integrating Ayurveda into Parkinson’s Management: A Holistic Approach

Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
