The upper tract includes the nose, nasal cavity, sinuses, pharynx and larynx. The lower tract includes the trachea, bronchi and bronchioles which branch into millions of alveoli in the lungs where gas exchange occurs. The document also outlines the processes of breathing, gas exchange, and the roles of various respiratory structures.
Human respiratory system
The document summarizes the structure and function of the human respiratory system. It describes that the respiratory system consists of respiratory tract and lungs. The respiratory tract includes the nose, nasal passages, pharynx, larynx, trachea, and bronchial tree. The lungs are located in the thoracic cavity and contain bronchioles and alveoli where gas exchange takes place. The diaphragm and intercostal muscles help in the mechanism of breathing by contracting and relaxing during inhalation and exhalation.
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.
The respiratory system report xxxx
The document describes various parts of the respiratory system and their functions, respiratory diseases including their symptoms, prevention and treatment methods. It discusses organs like nose, larynx, trachea, lungs and their roles. Diseases explained are COPD, sinusitis, pneumonia, bronchitis, lung cancer and their prevention through lifestyle changes and available treatments like surgery, chemotherapy, radiation therapy etc.
Respiratory System Notes
The document provides an overview of the human respiratory system, including its key functions, organs, and mechanics. The respiratory system functions to exchange gases, purify air, and produce sound. Its organs include the nose, pharynx, larynx, trachea, bronchi, and lungs. Within the lungs, gas exchange takes place in tiny air sacs called alveoli. Breathing is driven by the contraction and relaxation of the diaphragm and intercostal muscles, pulling air into and pushing air out of the lungs.
Respiration Physiology-Respiratory System
The respiratory system has three main functions: gas exchange between the atmosphere and blood, filtering and warming of inspired air, and sound production. It has three basic steps: pulmonary ventilation (breathing), external (pulmonary) respiration involving gas exchange in the lungs, and internal (tissue) respiration involving gas exchange in tissues. Inspiration is an active process using inspiratory muscles like the diaphragm and external intercostals to expand the thoracic cavity and lower lung pressure, allowing air to flow in. Expiration is usually a passive process involving elastic recoil of the lungs and chest wall. Other factors like alveolar surface tension, lung compliance, and airway resistance also influence ventilation.
The human respiratory system
The human respiratory system consists of the nasal cavity, which humidifies and filters air, the windpipe that transports air to the lungs, and the bronchi that divide the windpipe and conduct air into the lungs. The lungs are essential organs that transport oxygen into the bloodstream and release carbon dioxide. Air is composed primarily of nitrogen and oxygen, with around 1% water vapor.
Respiratory system
The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function. The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air. When something goes wrong with part of the respiratory system, such as an infection like pneumonia, it makes it harder for us to get the oxygen we need and to get rid of the waste product carbon dioxide. Common respiratory symptoms include breathlessness, cough, and chest pain.

Respiration occurs in two phases - inspiration and expiration. During inspiration, air enters the lungs via the respiratory tract which includes the nose, pharynx, larynx, trachea, bronchi and lungs. Expiration is the passive process where air leaves the lungs. Respiratory muscles like the diaphragm and intercostal muscles facilitate these processes. Gases are exchanged between the alveoli and blood in the lungs via diffusion. Carbon dioxide levels increase and oxygen levels decrease in tissues, triggering respiration.
The respiratory system
The respiratory system involves the exchange of gases through breathing. It consists of the upper respiratory tract which includes the nose, mouth, pharynx, larynx and trachea, and the lower respiratory tract which includes the lungs. The nose warms and filters inhaled air before it reaches the lungs. In the lungs, oxygen from the air diffuses into the blood in the alveoli while carbon dioxide diffuses out of the blood and into the alveoli to be exhaled. The circulatory system then transports oxygen to tissues and carbon dioxide away from tissues in a continuous exchange process.

The respiratory system consists of the upper respiratory tract (nasal passages), the airway conduction system (larynx, trachea, bronchi, bronchioles and terminal bronchioles), and the lower respiratory tract (alveolar ducts and alveoli). Not all segments of the respiratory system mature at the same pace. The olfactory epithelium matures earliest by PND 7. The lung, however, is not considered mature until PND 21, when alveolarization and microvascular maturation are complete. This chapter will discuss the embryological development (briefly), adult histomorphology, and postnatal histologic development of each major component of the respiratory system.

Respiratory system
The respiratory system is the one of vital organs that involve in respiration
Play important role in the intake and exchange of O2 and CO2 .
The respiratory system performs two major tasks:
Exchanging air between the body and the outside environment known as external respiration.
Bringing O2 to the cells and removing CO2 from them referred to as internal respiration.
Parts of respiratory system
Upper respiratory tract: (outside thorax)
Nose
Nasal Cavity
Pharynx
Larynx
Nose:
Also called external nares.
Divided into two halves by the nasal septum.
Contains the paranasal sinuses where air is warmed.
Contains cilia which is responsible for filtering out foreign bodies.
Pharynx:
Common space used by both the respiratory and digestive systems. Commonly called the throat.
Start from the nasal and oral cavities and extends inferiorly near the level of the bifurcation of the larynx and esophagus.
There are 3 types:
Nasopharynx
Oropharynx
Laryngopharynx
Larynx:
Voice box is a short, cylindrical airway - ends in the trachea.
Prevents swallowed materials entering into the lower respiratory tract.
It Passes air into the lower respiratory tract.
Produces sounds.
Supported by cartilage help to held in place by ligaments and muscles.
Voice is produced by vibration of the vocal folds or vocal cords. The vocal folds are a pair of pliable shelves of tissue that stretch across the top of the trachea (windpipe). They are enclosed within the thyroid cartilage. The vocal folds, together with the muscles and cartilages that support them, are known as the larynx.
Biologically, the larynx evolved as a valve to protect the airway and lungs. Thus, it is positioned where the airway and the esophagus separate. The vocal folds open to allow breathing and close during swallowing to prevent food from entering into the lungs and during voicing.
Trachea:
A flexible tube also called windpipe.
Extends through the mediastinum and lies anterior to the esophagus and inferior to the larynx.
Cartilage rings help the trachea to remains open at all times.
Bronchus:
The two large tubes that carry air from your windpipe to your lungs.
Left and right main bronchus in each lung.
Each bronchus divided into bronchioles
Lung:
Each lung has a conical shape. Its wide, concave base rests upon the muscular diaphragm.
Its superior part called the apex
Both lungs are supported anteriorly by thoracic wall, laterally, and posteriorly by the rib cage.
Mediastinum
Left lung: divided into 2 lobes by, smaller than the right lung & cardiac notch accommodates the heart
Right lung: divided into 3 lobes by, located more superiorly in the body due to liver on right side
Pleura:
The outer surface of each lung covered by a layer called pleura.
The outer - parietal pleura & the internal - visceral pleura.
Control of respiration
Like heartbeat, breathing must occur in a continuous, cyclic pattern to sustain life processes.
Inspiratory muscles must rhythmically contract and relax to alternately fill the lungs with air and empty them.
The rhythmic pattern of breathing is established by cyclic neural activity to the respiratory muscles

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.

PGx Analysis in VarSeq: A User’s Perspective
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

- 2. Respiratory System-includes Conducting airways-oral & nasal cavities Pharynx Trachea Bronchi Lungs Nerves controlling Respiration Structures to move air in & out: Rib cage , Intercostal muscles, Diaphragm,Abdominal muscles
- 4. Structure
- 5. Respiration: “Exchange of O2 and CO2 between the atmosphere and body cells ” STEPS involves 1.Pulmonary Ventilation 2.Diffusion of O2 & CO2 3.Transport of gases
- 6. 1.Pulmonary Ventilation Its means Inflow and outflow between atmosphere and lungs alveoli, Inspiration (contains O2) Expiration ( Contains CO2)
- 8. 2. Diffusion:- Oxygen from alveoli to blood. CO2 from blood to alveoli.
- 9. 3. Transport of Gases Transport of O2 and CO2 in blood and body fluid to and from the cells.
- 13. Basic Mechanism of respiration Mechanism of respiration involves the breathing mechanism and exchange of gases. The gaseous exchange occurs by diffusion in the alveoli. It depends upon the pressure differences between blood and tissues, or atmospheric air and blood. The exchange of gases takes place at the surface of the alveolus
- 14. Mechanism of Inspiration Inspiration is the phase of ventilation in which air enters to the lungs. It is initiated by contraction of the inspiratory muscles: Diaphragm - flattens, extending the superior/inferior dimension of the thoracic cavity.
- 15. Mechanism of Expiration Expiration is the process of releasing carbon dioxide from the body. During expiration, the diaphragm relaxes and the volume of the thoracic cavity decreases, and the pressure inside it increases. Consequently, the lungs contract and the air is forced out. https://teachmephysiology.com/respiratory- system/ventilation/mechanics-of-breathing/
- 16. Respiratory Rate: Respiratory rate: A person's respiratory rate is the number of breaths take per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute. A respiration rate under 12 or over 25 breaths per minute while resting is considered abnormal.
- 18. Respiratory Tidal Volume: Tidal volume is the amount of air that moves in or out of the lungs with each respiratory cycle. It measures around 500 mL in an average healthy adult male and approximately 400 mL in a healthy female. It is a vital clinical parameter that allows for proper ventilation to take place. Tidal volume (Vt or TV) is a physiological term used to describe the amount of air typically moved during inspiration and expiration while at resting. It is measured by spirometry. an average, adults breathe 7 milliliters (mL) per kilogram (kg) of ideal body weight.
- 20. Rate and control of respiration The apneustic (stimulating) and pnuemotaxic (limiting) centers of the pons work together to control rate of breathing. The medulla oblongata sends signals to the muscles that initiate inspiration and expiration, and controls nonrespiratory air movement reflexes, like coughing and sneezing.
- 21. Nervous control The phrenic nerves, vagus nerves, and posterior thoracic nerves are the major nerves involved in respiration. Voluntary respiration is needed to perform higher functions, such as voice control.
- 22. Chemical control It is regulated by both reflex and chemical mechanisms. The chemical regulation of respiration concerns the hydrogen ion content of the respiratory neurones which in turn is dependent upon the carbon dioxide tension of the blood and the rate of flow of blood through the medulla Oblongata.
- 23. Transport of Oxygen and Carbon Dioxide in Blood and Tissue Fluids. In the body's tissue cells, oxygen reacts with various foodstuffs to form large quantities of carbon dioxide. This carbon dioxide enters the tissue capillaries and is transported back to the lungs.
