Respiration
The document summarizes key aspects of the respiratory system. It discusses that respiration provides oxygen for metabolism and removes carbon dioxide, and also facilitates smell and speech. It describes the functions of external and internal respiration. It outlines the passageways of air from the nasal cavity and pharynx down to the alveoli. It discusses the lungs as the site of gas exchange and pulmonary circulation. It also summarizes control of breathing including local control to maintain ventilation-perfusion ratio and central control through respiratory centers and respiratory reflexes.
respiratory system 54172for anatomy students.ppt
The respiratory system allows for gas exchange between the external environment and tissues within the body. It includes the nose, pharynx, larynx, trachea, bronchi, bronchioles and lungs. The lungs are divided into conducting and respiratory zones. In the conducting zone, air is warmed and filtered before reaching the alveoli in the respiratory zone, where oxygen and carbon dioxide are exchanged with blood. Breathing is controlled by respiratory centers in the brain and is influenced by chemoreceptors sensitive to oxygen, carbon dioxide and pH levels. Disorders that can affect the respiratory system include chronic obstructive pulmonary disease, lung cancer, pneumonia and tuberculosis.
Ventilators
This document provides information about ventilation and mechanical ventilation. It defines ventilation as the process of moving air in and out of the lungs for gas exchange. Mechanical ventilation is the use of a device to provide artificial breathing when a patient cannot maintain adequate oxygen and carbon dioxide levels on their own. The document discusses the mechanics of normal breathing and ventilation, as well as the components, controls, phases and physiological principles of mechanical ventilation. It provides indications for mechanical ventilation and factors that affect ventilation such as lung compliance, airway resistance, and work of breathing.
Resp Physio and PFTmade by me welcome to
This document discusses respiratory physiology and pulmonary function tests. It covers the mechanics of respiration including the roles of the diaphragm and accessory muscles. It also discusses the controls of respiration in the medulla and pons, and the factors that control the rate and depth of breathing like oxygen, carbon dioxide and pH levels. Nerve supply, intra-thoracic pressures, lung mechanics, compliance, volumes and classifications of lung defects are summarized. Common pulmonary function tests are then described like spirometry, plethysmography, diffusion capacity testing and what measurements each provides.
Neural regulation of Respiration
This document discusses the neural regulation of respiration. It begins by outlining the respiratory centers located in the brainstem, including the dorsal respiratory group, ventral respiratory group, pneumotaxic center, and apneustic center. These centers generate the rhythmic pattern of breathing and control the rate and depth of respiration. The document then describes various inputs that affect the respiratory centers, including peripheral chemoreceptors, lung stretch receptors, and irritant receptors. It concludes by explaining how disrupting different parts of the respiratory control system, such as through brainstem transections or anesthesia overdose, can impact breathing patterns and potentially cause respiratory arrest.
Ventilation (1)
The document describes the anatomy and physiology of the respiratory system.

Principles of icu ventilators
Mechanical ventilators are machines that assist or replace patient breathing. They have several key components, including an input power source, drive mechanism, control circuit, and ability to generate specific output waveforms. Ventilators are classified based on whether they use positive or negative pressure to support breathing. Positive pressure ventilators are now more commonly used and deliver gas by exerting pressure on the airway. They can control ventilation based on parameters like pressure, volume, flow, or time. Modern microprocessor-controlled ventilators provide closed-loop servo control to precisely match patient needs.

Johny's A&P physiology of respiration
The document discusses the process of respiration in four parts:
1. Pulmonary ventilation involves breathing air in and out of the lungs through inhalation and exhalation.
2. External respiration is the exchange of oxygen and carbon dioxide between the alveoli in the lungs and blood in the pulmonary capillaries.
3. Internal respiration is the exchange of gases between blood in the systemic capillaries and tissue cells throughout the body.
4. Respiration is regulated through various pulmonary volumes including tidal volume, vital capacity, functional residual capacity, and total lung capacity.

Physio chapter 13 lungs
The document summarizes key aspects of the respiratory system, including:
- External respiration involves gas exchange between the lungs and blood, transporting oxygen to tissues and carbon dioxide away. Internal respiration occurs via cellular respiration in mitochondria.
- The respiratory tract involves the nose, pharynx, larynx, trachea, bronchi and bronchioles leading to alveoli where gas exchange occurs by diffusion across pulmonary capillaries.
- Breathing is driven by changes in thoracic pressure and lung volumes via contraction of respiratory muscles and elastic recoil of the lungs and chest wall. Inspiration occurs as lungs fill a expanded chest cavity, expiration when it relaxes.
The Respiratory System
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
The respiratory system
The respiratory system allows for oxygen to enter the body and carbon dioxide to exit through a series of major organs. Air enters through the nose or mouth and passes through the pharynx, larynx, trachea, bronchi and into the lungs where gas exchange occurs in the alveoli. Oxygen then passes into the bloodstream and carbon dioxide passes out of the bloodstream and is exhaled. Breathing is facilitated by the contraction and relaxation of the diaphragm and rib cage which expands and contracts the chest cavity to inhale and exhale air.

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).

- 3. First the body breathes in the air which is sucked through the nose or mouth and down through the trachea (windpipe). The trachea is a pipe shaped by rings of cartilage. It divides into two tubes called bronchi. These carry air into each lung. Physiology
- 5. Inside the lung, the tubes divide into smaller and smaller tubes called bronchioles. At the end of each of these tubes are small air sacs called alveoli. Physiology
- 6. Capillaries, which are small blood vessels with thin walls, are wrapped around these alveoli. The walls are so thin and close to each other that the air easily seeps through. In this way, oxygen seeps through into the bloodstream and carbon dioxide, in the bloodstream, seeps through into the alveoli, and is then removed from the body when we breathe out. Physiology
- 7. The diaphragm is the muscle that controls the breathing process. As the diaphragm flattens it causes the chest to expand and air is sucked into the lungs. When the diaphragm relaxes, the chest collapses and the air in the lungs is forced out. Physiology
