Anatomy Essays 2

The nose that protrudes from the bone and the outer part supported by the cartilage is separated from the midline nasal septum and is lined with mucosa. The nose creates mucus, warms and moisturizes the air entering the filter, and the resonance chamber is used for the voice. The paranasal sinus is a mucosal lining in which the cavity filled with air in the skull surrounding the nasal cavity lightens the skull and has the same function as the nasal cavity. The pharynx connects the nasal cavity to the throat, and the mouth to the esophagus. Three compartments that serve as channels for air and food include tonsils. The larynx connects the pharynx to the trachea, cartilage and dense connective tissue and prevents food from entering the lower respiratory tract and adapting to the vocal cords.

Secretion fluids including mucous / serous gonads, lysozyme, antibacterial agents, stickiness, trapped dust, bacteria and other debris, lysozyme chemical attack also secrete defensins. Sneezing is caused by irritating particles entering the nose. And it explodes air and particles. Air turbulence is caused by nasal cavities surrounded by air, which adhere non-gaseous particles to mucus. If you are hanging you can prevent food from entering the nasal cavity

The conducting region is the channel through which air passes until it becomes a bronchial tree, branching to an increasingly smaller channel and as the lungs arrive, the bronchial tree becomes increasingly smaller. When the terminal bronchioles enter the pulmonary respiratory bronchioles, the respiratory zone begins with the alveolar sac and ends in the alveolar sac.

The wall is composed of monolaytic squamous epithelial cells called type I cells, mainly surrounded by the basement membrane. The alveoli covers the pulmonary capillaries and the walls fuse together to form a respiratory membrane with gas flow on one side of the respiratory membrane and blood flow on the other side. Type II cells disperse and secrete a surfactant that covers the exposed alveolar surface of the gas and secretes antimicrobial proteins.

In addition to the mediastinum, the lungs occupy the entire chest and are suspended in each thoracic pleural cavity, each pleural cavity containing segments that function by their respective arteries, veins and bronchi. Lung tissue consists mainly of voids, and the matrix consists of elastic connective tissue. In the lung it is used for 2 cycles, the primary lung network carries whole blood to the lungs and supplies blood to the lung tissue. The pleura forms a bilayer serosa, the crown covering the chest wall on the diaphragm, around the heart, continuing between the lungs, and the viscera covers the outer surface of the lungs

Lung pressure is the pressure in the alveoli that goes up and down during breathing, but it is always equal to atmospheric pressure.

Pleural pressure is the pressure within the pleural space. It moves up and down during breathing, but it is always about 4 mm lower than lung pressure.

The amount of pleural effusion in the pleural space must be kept to a minimum to maintain negative Pip. Pleural effusion is continuously fed into the lymph duct from the pleural cavity. Otherwise, the fluid accumulates in the pleural space and causes positive pressure in the pleural space.

Explain the relative role of respiratory muscle and lung elasticity in causing volume change to flow air inside and outside the lung

Anatomy is divided into macroscopic anatomy and microscopic anatomy. Macroscopic anatomy or gross anatomy is the examination of parts of the body of animals using the naked eye. Macroscopic anatomy also includes branches of surface anatomy. Microanatomy involves the organization of various structures called histology, and the use of optical instruments to study cellular research. The historical feature of anatomy is the progressive understanding of the function of human organs and structures. This method has also been significantly improved by dissecting corpses and corpses (in their 20s) into 20th century medical imaging techniques (including X-ray, ultrasound and magnetic resonance imaging).

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form images of the anatomical and physiological processes of the body in health and disease. MRI scanners use strong magnetic fields, magnetic field gradients and radio waves to generate visceral images. MRI uses ionizing radiation that does not use x-rays or is distinct from CT or CAT scans and PET scans. Magnetic resonance imaging is a medical application of nuclear magnetic resonance (NMR). NMR can also be used for imaging in other NMR applications such as NMR spectroscopy.
