The lungs presentation ch.2
The document summarizes the structure and function of the lungs. It describes that the lungs are part of the respiratory system and are responsible for bringing oxygen into the body and removing carbon dioxide. The lungs contain bronchi, bronchioles, and alveoli where gas exchange occurs. Various lung diseases and conditions are also outlined such as lung cancer, silicosis, asthma, pneumonia and COPD. Tips for maintaining healthy lungs include not smoking, exercise, and a healthy diet.
HUMAN RESPIRATORY SYSTEM ANATOMY & PHYSIOLOGY
The respiratory system allows for gas exchange of oxygen and carbon dioxide. It includes the nose, pharynx, larynx, trachea, bronchi, bronchioles and lungs. The upper respiratory tract includes the nose, nasal cavity and sinuses which warm, moisten and filter inhaled air. The lower respiratory tract includes the lungs and airways inside the chest. The lungs contain bronchioles and alveoli where gas exchange occurs. During respiration, oxygen is absorbed into the blood from the alveoli and carbon dioxide is released, in a continuous cycle of breathing in and out.
Respiratory System
The respiratory system allows for gas exchange in the body. It begins with the nostrils, where air enters and exits the nasal cavity to be warmed. The pharynx and larynx allow air to pass to the trachea and then bronchi, where air flows into the lungs. The lungs, located in the chest, have lobes and facilitate breathing, respiration, and protection from infection. Inhalation draws oxygen into the lungs through muscle contraction and exhalation removes carbon dioxide as a waste product.

The lungs presentation
The lungs are the essential organs for respiration in air-breathing animals. In humans, the trachea divides into the two main bronchi that enter the roots of the lungs, continuing to branch into bronchioles and alveolar sacs made up of clusters of alveoli where gas exchange occurs. The principal function of the lungs is to transport oxygen into the bloodstream and release carbon dioxide, with differences in lobe structure between human and pig lungs.
Resperattory system
The document describes the anatomy and physiology of the respiratory system. It discusses the structures of the respiratory system including the upper and lower airways, pleura, lungs, thorax, diaphragm and respiratory centers. It also describes the processes of respiration including ventilation, diffusion, and gas exchange. Furthermore, it outlines how to assess a client with a respiratory disorder through obtaining history, performing a physical exam including inspection, palpation, percussion and auscultation of breath sounds.
Respiratory system
The human respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, lungs, and alveoli. The nose and nasal cavity warm and filter incoming air. The pharynx and larynx are passageways that lead to the trachea, which divides into the left and right bronchi and further branches into bronchioles and alveoli within the lungs. Gas exchange occurs in the alveoli, where oxygen passes into the bloodstream and carbon dioxide passes out.
Human Respiratory System
The respiratory system is comprised of several organs involved in breathing, including the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles and lungs. Air enters through the nose or mouth and passes through these structures made of cartilage, muscle and mucous membranes to warm, moisten and filter the air before it reaches the lungs. In the lungs, the air flows through increasingly smaller airways called bronchioles until reaching tiny air sacs called alveoli where oxygen and carbon dioxide are exchanged.

The circulatory system complete Info ppt
The circulatory system transports blood, nutrients, gases, hormones, and wastes throughout the body. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood through two circuits - the pulmonary circulation and the systemic circulation. It has four chambers and uses valves to ensure one-way blood flow. The cardiovascular system is regulated by both intrinsic and neural factors. Diseases can occur if the circulatory system is not functioning properly.
Pulmonary circulation
The pulmonary circulation involves the movement of blood from the heart to the lungs and back to the heart. Deoxygenated blood enters the right atrium from the body and is pumped to the right ventricle and then into the pulmonary artery to the lungs. In the lungs, the blood releases carbon dioxide and picks up oxygen. It then returns via the pulmonary veins to the left atrium and is pumped by the left ventricle back out to the body. The purpose is to oxygenate the blood through gas exchange that only occurs in the lungs.

Alveolar Capillary Unit
1. The alveolar-capillary unit is a complex structure that facilitates gas exchange through diffusion between alveoli and surrounding capillaries. It provides a thin barrier and large surface area for oxygen and carbon dioxide exchange.
2. Surfactant, produced by type II alveolar cells, reduces surface tension in alveoli to increase lung compliance and prevent collapse during expiration. It plays several roles including reducing work of breathing and stimulating the lung's immune system.
3. Gas exchange occurs through diffusion as blood passes through alveolar capillaries. Oxygen diffuses into the blood from alveoli while carbon dioxide diffuses out of the blood into alveoli based on partial pressure gradients
Cell respiration and metabolism
Cellular respiration involves the breakdown of glucose and other molecules like fatty acids and amino acids to extract energy through a series of metabolic pathways. Glucose undergoes glycolysis to form pyruvate, which can then enter the Krebs cycle after converting to acetyl-CoA. This releases electrons that are passed through the electron transport chain, powering ATP production through oxidative phosphorylation as the electrons are transferred to oxygen. Fatty acids undergo beta-oxidation to form acetyl-CoA molecules, while excess amino acids are deaminated and their carbon skeletons fed into the Krebs cycle.
Non respiratory functions of lung2
The lungs have several metabolic functions beyond gas exchange, including defence against pathogens, maintenance of water balance, temperature and acid-base regulation, and metabolism of substances. The lungs are protected by physical, cellular and biochemical defences at different levels of the respiratory tract. Mucus, cilia, coughing, and alveolar macrophages help clear particles and pathogens from the lungs. The lungs also play roles in systemic functions such as water and heat regulation, acid-base balance, and metabolism of hormones and vasoactive substances.

It also addresses habitat destruction, pollution of land, water and air from sources such as insecticides, sewage, and greenhouse gases, as well as conservation efforts like sustainable resources, endangered species protection, and reducing pollution.
Biology notes - topic 8
The document discusses how nerve cells transmit impulses through the nervous system. It explains that:
- Nerve cells have a resting potential of around -70mV due to the distribution of ions inside and outside the cell.
- When a nerve is stimulated, it causes voltage-gated sodium channels to open, allowing sodium ions to rush in and depolarize the cell. This creates an action potential.
- The cell then repolarizes as sodium channels close and potassium channels open, restoring the resting potential and allowing another impulse to be transmitted.
- This process of depolarization and repolarization via ion channel activation allows rapid and efficient transmission of nerve impulses through the nervous system.

the lungs
The lungs are essential organs for respiration that transport oxygen from the atmosphere into the bloodstream and release carbon dioxide back out. They are located in the chest cavity on either side of the heart. The trachea branches into the two main bronchi that enter each lung and continue dividing into smaller bronchioles and alveolar sacs where gas exchange occurs between blood in the lungs and inhaled air. Lung diseases can affect this vital function and include cancer, infections like pneumonia, and occupational illnesses caused by inhaling harmful particles.

C:\fakepath\taiwo's chapter 2 presentation
The lungs are a pair of cone-shaped organs located in the chest that bring oxygen into the body and release carbon dioxide. Each lung is made up of lobes and surrounded by a membrane called the pleura. The diaphragm works with the lungs to allow breathing. The main function of the lungs is respiration, which is the process of inhaling oxygen and exhaling carbon dioxide through the respiratory airways and into the lungs. Common lung diseases include pneumonia, tuberculosis, lung cancer, and emphysema.

The lungs are a pair of cone-shaped organs located in the chest that bring oxygen into the body and release carbon dioxide. Each lung is made up of lobes and surrounded by a membrane called the pleura. The lungs work with the diaphragm to inhale air and exhale carbon dioxide through a process called respiration. Respiration brings oxygen into the blood and removes carbon dioxide, which is essential for cells to function.
Gaseous Exchange
The document discusses gaseous exchange and respiration in plants and humans. In plants, gaseous exchange occurs through stomata in leaves and lenticels in stems. Photosynthesis and respiration regulate gas exchange. In humans, respiration involves the respiratory system including the nose, pharynx, larynx, trachea, bronchi, bronchioles and alveoli where gas exchange occurs. The lungs and associated muscles and diaphragm facilitate inhalation and exhalation. Common respiratory diseases like bronchitis, emphysema and pneumonia are also summarized.
states of matter
The human respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles and lungs. Air enters the nose and is warmed and filtered before reaching the lungs. In the lungs, gas exchange occurs as oxygen diffuses into the bloodstream in the alveoli and carbon dioxide diffuses out. Oxygen is transported to cells by hemoglobin in red blood cells. Poor air quality and smoking can damage lungs and cause respiratory diseases like asthma, pneumonia and lung cancer. Maintaining good respiratory health requires reducing pollution and avoiding smoking.

Copd ppt
Chronic obstructive pulmonary disease (COPD) is characterized by not fully reversible airflow limitation caused by conditions like emphysema and chronic bronchitis. It makes it difficult to get oxygen and remove carbon dioxide. The respiratory system brings oxygen into the body through a pipe-like structure from the nose to tiny air sacs in the lungs called alveoli. In the alveoli, oxygen passes into the bloodstream and carbon dioxide passes out of the bloodstream and into the lungs to be exhaled. When parts of the respiratory system are damaged, like in COPD, this gas exchange is impaired.

Respiratory system for Msefah
The respiratory system includes the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs. The nasal cavity conditions incoming air. The pharynx serves both respiratory and digestive functions. The larynx contains cartilages that allow for vocalization and protect the trachea. The trachea transports air to the bronchi and bronchioles in the lungs. In the lungs, oxygen enters the bloodstream and carbon dioxide leaves in the alveoli. Common respiratory conditions include asthma, pneumonia, and COPD.
Respiratory system
The respiratory system consists of the pharynx, larynx, trachea, bronchi, alveoli, and diaphragm. The pharynx is a passageway for food and air and contains the epiglottis. The larynx holds the vocal cords and is covered by the epiglottis during swallowing. The trachea is a cartilage-reinforced tube that branches into the bronchi and carries air into the lungs. The bronchi branch into smaller bronchioles that lead to clusters of alveoli, which are tiny sacs surrounded by capillaries where gas exchange occurs. The diaphragm is a muscle that contracts and relaxes to help breathe air in and

Novas diretrizes da OMS para os cuidados perinatais de mais qualidade
Novas diretrizes da OMS para os cuidados perinatais de mais qualidadeProf. Marcus Renato de Carvalho
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.
Esta publicação só está disponível em inglês até o momento.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Lung presentation 2
- 1. LUNGS By Demetrius Bates
- 2. Respiratory System Brief The lungs are one of six organs in the respiratory system. The other five organs include: nasal cavity, pharynx, larynx, trachea and bronchial tubes.
- 3. Functions of the Lung The lungs are essential respiration organ that is located in all breathing mammals. The lungs transport oxygen from the atmosphere into the bloodstream. Then, the lungs release carbon dioxide from the bloodstream back into the atmosphere.
- 4. Structure of the Lungs Theoretically, there should be a right an left lung in your chest. The left being smaller than the right lung due to the fact that there is less space in the pleural cavity because of the mass of the heart. The left lung contains only 2 lobes and the right has 3 lobes.
- 5. Structure of the Lungs Cont. Each lung consist of bronchi, bronchioles and alveoli.
- 6. Structure of the Lungs Cont. Bronchi are pipes leading from the trachea to each lung. Bronchioles are smaller and smaller branches of bronchi. Alveoli are very little small sacs at the ends of the smallest bronchioles where oxygen gets into the blood and carbon dioxide exits.
- 7. Structure of the Lungs Cont. The lungs are spongy because they contain air. The lungs are protected by membrane called pleural.
- 8. Examples of Ailments of the Lung Asthma: a disease the affects the lungs by the constriction of the bronchial airways. Can cause violent spasms of the bronchi. Maybe caused by various allergens. Emphysema: a pulmonary condition that characterized by destruction of the walls of the alveoli resulting in fewer over expanded air sacs. Can be caused by smoking and sometimes the air you breathe.
- 9. Examples of Ailments of the Lung cont’d Pneumonia: an inflammatory condition of the lung that can be caused by bacteria and viral infections, diseases, and chemicals. Resulting in the alveoli spaces filled with fluids. Tuberculosis (TB): an infectious disease caused by bacteria. It affects the respiratory system and causes inflammation and calcification in the lungs.
- 10. Visual of Healthy vs. Non Healthy Lungs The lung on the left is a healthy lung and the one the right is an unhealthy lung:
