The second half of the human airways, continuing after the larynx, including the trachea, bronchi, and the respiratory structures within the lungs – the, bronchioles, and alveoli, is referred to as the lower respiratory tract [1, 2]. The release of end products of digestion from the gastrointestinal tract is regulated by the external anal sphincters. The lungs are most often considered as part of the lower respiratory tract, but are sometimes described as a separate entity. They also have an excellent blood supply. The brain senses the lack of oxygen and sends a signal, making you take a long deep breath, that is, a yawn. Also learn about its functions. The inner membrane of the trachea is covered in tiny hairs called cilia, which catch particles of dust which we can then remove through coughing. We also excluded ear infections without other URTI symptoms, and infections following surgical or medical interventions. When it contracts, it becomes flattened and therefore increases the volume of the thoracic cavity. the airway network that leads to the lungs and then branches out into the various lung segments resembles an upside down tree and is sometimes called the tracheobronchial tree. Pharynx- Acts in the respiratory and the digestive system. The nasal cavity is a hollow space within the nose and Alveoli (alveolus), the last part of the lower respiratory tract, are the tiny air sacs located in clusters at the end of the bronchioles [8]. Paranasal sinuses: Air-filled spaces surrounding the nasal cavity. The basic organizational pattern is that of a gland, in which a branching tree of tubes provides continuity from the body's outside surface to a vast number of epithelial cells.

The breathing rate in women and children is slightly faster than that of men. In addition to these organs, certain muscles of the thorax (the body cavity that fills the chest) are also involved in respiration by enabling breathing. functions of respiratory system :. Similarly, contraction of the external intercostal muscles moves the ribs upwards and outwards. See separate leaflets about other infections of the respiratory tract and related structures, called Bronchiolitis, Pneumonia, Tonsillitis, Sore Throat, Acute Sinusitis and Pleurisy. The major passages and structures of the lower respiratory tract include the windpipe (trachea) and within the lungs, the bronchi, bronchioles, and alveoli. Nasal cavity and nostrils: They mark the main entrance to the respiratory system as air passes through them into the next part of the airways. The respiratory system in humans has the following important features. The muscular pipe has small cartilaginous rings surrounding and supporting it, preventing it from collapsing under the changing air pressure during inhalation and exhalation [5].

Larynx (voice box): A flexible yet tough segment, larynx connects the pharynx to the trachea. The energy is generated by the breakdown of glucose molecules in all living cells of the human body. Cilia constantly clean the tract and carry foreign matter upwards for swallowing or expectoration. Two squashy, air-filled lungs are located at the left and right sides of the thorax (chest), both protected by the rib cage. Extending from the larynx, the trachea branches into two primary bronchi, which eventually lead to the lungs. Greek: éntera ) is the segment of the gastrointestinal tract extending from the pyloric sphincter of the stomach to the anus and, as in other mammals, consists of two segments, the small intestine and the large intestine . An analysis to produce a The trachea branches into the left and right bronchi, which then enters the left and right lungs respectively. Pharynx, epiglottis, trachea, larynx, tracheal cartilages, sinuses, and tonsils - anatomy and physiology of the upper respiratory tract. So to get started on that, we're going to start by labeling the trachea. In ancient Egypt, the windpipe and lungs together served as a symbol of unity between the Upper and the Lower Egypt.

The inhaled air enters the lungs through the trachea and bronchi. Lower respiratory tract The trachea , or windpipe, is the passage that allows air to flow directly to the lungs. The short flexible bronchi are also surrounded by cartilage rings [6]. Features of the Human Respiratory System . The upper and lower respiratory tracts communicate with each other through a number of mechanisms. Yawning occurs when the respiratory system does not receive enough oxygen through inhalation. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. Symptoms may include: breathlessness or wheezing; persistent, new or changed cough; chest pain; coughing up blood, mucus or phlegm; Serious respiratory conditions can cause long-term illness or death. It includes the trachea, or windpipe; the bronchi, which are the two branches of the trachea that penetrate the lungs; the lungs themselves; and the bronchioles and alveoli within the lungs, where gas exchange takes place. To breathe simply means inhaling oxygen and exhaling carbon dioxide. Once the bronchi enter the lungs, they start branching further into smaller airways – first into the secondary bronchi, then the tertiary bronchi, to finally divide into the smallest branches of the airways, the bronchioles [7]. Respiratory tract infections (RTIs) are a series of clinical syndromes covering the common cold, rhinitis, nasopharyngitis, bronchitis, epiglottitis, laryngitis, tracheitis, tracheobronchitis, pneumonia, and other upper respiratory tract infections (URTIs) and lower respiratory tract infections (LRTIs) . This is the primary respiratory area within the human body, where the inhaled air travels through the trachea, bronchi, and bronchioles, and comes in contact with the blood capillaries so the oxygen and carbon-dioxide exchange can take place.
