The respiratory system
The respiratory system begins in the larynx in the throat and includes the trachea, bronchus, alveolus, bronchioles, and lungs. The diaphragm and lungs work together to inhale oxygen and exhale carbon dioxide, moving gases to and from the blood through the respiratory tree. The respiratory system is vital for breathing and distributing oxygen throughout the body.
The respiratory system
The document summarizes the key components and functions of the respiratory system. It describes how the respiratory system takes in oxygen and removes carbon dioxide through a series of tubes and airways. These include the trachea, bronchi and bronchioles which distribute air to the lungs. The lungs then pass oxygen to the bloodstream and remove carbon dioxide, while the diaphragm aids breathing through its contraction and relaxation.
Respiratory system
The respiratory system allows us to breathe in oxygen and breathe out carbon dioxide. It begins with air being filtered through the nose and warmed in the nasal passages. The pharynx carries air into the windpipe and pushes food into the gullet. The epiglottis covers the larynx to prevent food from entering the lungs. The larynx contains the vocal cords which produce sounds. The trachea takes air from the larynx to the lungs. In the lungs, the bronchial tree branches like a tree to distribute air to all parts of the lungs.

The respiratory system supplies blood with oxygen and removes carbon dioxide. It includes the larynx, trachea, bronchi, lungs, diaphragm, and alveoli. The larynx produces sound and protects the trachea. The trachea is also called the windpipe and connects the larynx to the lungs, allowing air passage. Bronchi are large air tubes that branch inside the lungs and connect to the trachea. The lungs transport oxygen into the blood and release carbon dioxide. The diaphragm is the main breathing muscle and expands the lungs to fill with air. Alveoli are small air sacs in the lungs where gas exchange occurs.
Respiratory system
The respiratory system enables breathing through the contraction and relaxation of the diaphragm and ribs. Air enters through the mouth and nose, travels through the trachea and bronchi into the lungs, which contain bronchioles and alveoli that facilitate gas exchange with blood capillaries. During inhalation, the diaphragm contracts and ribs rise to draw air through the trachea into bronchioles and alveoli. Exhalation occurs as the diaphragm relaxes and lungs deflate, pushing carbon dioxide out through the same pathways.

Robotics map based navigation in urban
The document describes a method for mobile robots to navigate in large urban environments using existing geographical information system (GIS) maps. It proposes using GIS maps of urban areas that are already in a standard, human-understandable format. The robot map format stores spatial information as geometric entities inspired by GIS vector formats. It represents obstacles as polygons, curves, or special cases like stairs and ramps. Segment and obstacle data includes location, height, type and semantic information. The representation scales to large environments while maintaining reasonable memory and computation. An experiment applies this mapping approach for robot navigation in a university campus environment.

Respiratory System.Chapter # 7
The respiratory system allows humans to breathe and is made up of the upper and lower respiratory tract. The upper tract includes the nasal cavity, pharynx and larynx, while the lower tract contains the trachea, bronchi, bronchioles and lungs. The lungs exchange oxygen and carbon dioxide through alveoli and are protected by the rib cage. Breathing is powered by the diaphragm and intercostal muscles. Maintaining a healthy respiratory system requires not smoking, exercising and avoiding pollution.
Respiratory system
The document describes the process of respiration and the structures involved in gas exchange in the human respiratory system. It explains that oxygen is absorbed into the blood and carbon dioxide is released from the blood in alveoli, tiny air sacs found in the lungs. A series of tubes called the windpipe and bronchi transport air to and from the lungs, where gas exchange with blood takes place across the thin membranes of the alveoli.
Respiratory System
The respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, lungs and alveoli. It brings oxygen into the body through the airways and into the bloodstream in the lungs. It also removes the waste product carbon dioxide by exporting it out of the bloodstream and airways. The respiratory system works with muscles like the diaphragm to inhale and exhale air for gas exchange in the alveoli between oxygen in the air and carbon dioxide in the blood.
Respiratory system
The respiratory system takes oxygen into the body through the nose and mouth and transports it via the trachea and bronchi to the lungs. In the lungs, oxygen passes through bronchioles and into alveoli where it is exchanged for carbon dioxide. Red blood cells then carry the oxygen throughout the body and remove carbon dioxide, which is exhaled through the respiratory tract. Key components that aid breathing include the diaphragm and lungs.
Respiratory system
The respiratory system performs several important functions: it transports oxygen to tissues, eliminates carbon dioxide and other waste from the body, and protects the body through reflexive actions. Key components include the larynx containing the vocal cords, trachea which is the pathway for air, bronchi and bronchioles which branch into the lungs, and alveoli in the lungs where gas exchange occurs. The diaphragm and lungs work together to inhale and exhale air which flows through the trachea and bronchi.
The respiratory system
The respiratory system is vital for survival as it allows oxygen to enter and carbon dioxide to exit the body. It includes the trachea that carries air to and from the lungs, bronchial tubes that branch out from the trachea and distribute air to small air sacs called alveoli where gas exchange occurs, and a diaphragm and vocal cords that help with breathing and voice functions.
Human respiration mee
The human respiratory system includes the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles, and lungs. Air enters through the nose or mouth and is warmed and filtered before passing to the pharynx and trachea. The trachea divides into bronchi that branch into smaller bronchioles and terminate in alveoli in the lungs. The alveoli are surrounded by capillaries where oxygen diffuses into the bloodstream and carbon dioxide diffuses out. Breathing is facilitated by the diaphragm muscle. The respiratory system works to oxygenate the blood and remove carbon dioxide
Respiratory system
The respiratory system has several main organs that work together to allow us to breathe. The lungs are the largest organ and work with tiny air sacs called alveoli to absorb oxygen into the bloodstream and release carbon dioxide. Pollution and smoking can damage the respiratory system by affecting the trachea, bronchi and bronchioles which are tubes that carry air to and from the lungs. The diaphragm and larynx also play important roles in breathing.

The Respiratory System
The respiratory system allows us to breathe in oxygen and breathe out carbon dioxide. It has two main zones - the conductive zone which brings air to the lungs through the nose, mouth, throat, trachea and bronchi, and the respiratory zone where gas exchange occurs in tiny air sacs called alveoli surrounded by capillaries. In the alveoli, oxygen passes into the bloodstream and carbon dioxide passes out through the thin walls of the alveoli and capillaries. Diseases and injuries can damage the respiratory system, but exercise and avoiding pollution can help strengthen it.

Key parts that are discussed include the alveolus, which holds air in the lungs and allows for gas exchange; the diaphragm, the main muscle that controls breathing; and the lungs, trachea, bronchi, and bronchioles which make up the air passageways allowing air to reach the alveoli.
Respiratory system
The respiratory system consists of the nose, pharynx, larynx, trachea, bronchi and lungs. The nose, pharynx, larynx, trachea and bronchi work like a system of pipes to funnel air into the lungs. In the lungs, oxygen is brought into the bloodstream in small air sacs called alveoli while carbon dioxide is removed from the blood and pushed out of the body. When something goes wrong with the respiratory system, such as an infection, it makes it harder to get oxygen and remove carbon dioxide, causing common symptoms like breathlessness, cough and chest pain.
Respiratory System Powerpoint
The primary function of the respiratory system is to supply blood with oxygen and remove carbon dioxide waste from cells. The respiratory system includes the nasal cavity, mouth, pharynx, trachea, lungs, bronchi, bronchioles, alveoli, and capillaries. Air enters through the nose or mouth and travels through the pharynx, trachea, bronchi, bronchioles, and into the alveoli where gas exchange occurs. Oxygen passes from the alveoli into the bloodstream and carbon dioxide passes from the bloodstream into the alveoli to be exhaled. Keeping the respiratory system healthy includes avoiding smoking, pollution, and exercising regularly.
Respiratory system[1]
The respiratory system performs three important functions for the air we breathe: warming it, moistening it, and filtering it. It is made up of the nasal passage, pharynx, epiglottis, larynx, trachea, bronchi, bronchioles, and alveoli. The lungs contain no muscle tissue, so breathing is driven by the diaphragm and intercostal muscles increasing and decreasing the space in the chest cavity. Cellular respiration uses oxygen to extract energy from foods through the breakdown of glucose.

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.Artificial Intelligence Symposium (THAIS)

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.
Pharmacology of 5-hydroxytryptamine and Antagonist
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
