1. Why does the trachea lined with pseudostratified ciliated columnar epithelium while the alveoli are lined with simple squamous epithelium? The trachea is lined with pseudostrastified ciliated columnar epithelium because the globlet cells that are there produce sticky mucous to coat the inner lining and catch any debris in inhaled air before it gets to the lungs. The columnar cells have cilia that push mucous away from the lungs. The alveoli are lined with simple squamous epithelium because the very thin epithelium will facilitate the diffusion of oxygen and carbon dioxide.
The four systems are the digestive system, the respiratory system, the circulatory system, lymphatic system and the urinary system. The digestive system is divided into two sections i.e. the alimentary canal this is about nine meters long which starts from the mouth and ends at the anus. The second section is the accessory organs these are organs which assist with digestion, absorption and storage of food substances. This includes the pancreas, liver and the gall bladder.
The Ostiomeatal Complex Overview The paranasal sinuses are believed to assist with several mechanical and physiological functions. These include humidifying inspired air, lightening the skull, regulating intranasal pressure, enhancing olfaction and adding resonance to the voice. Additionally, it has been postulated that the sinuses produce mucous that is free of environmental contaminants. This mucus is then secreted into the superior and middle meatus in order to mitigate the contamination present in the mucous that is in contact with the air and its contaminants. These functions would be compromised in instances where the paranasal sinuses are filled with fluid and are unable to be drained.
Another reason of why I believe he died of rabies is because Dr. Benitez reported him having a hard time drinking water or alcohol. In the New York Times article, he states, "In the brief period when he was calm and awake, Poe refused alcohol and could drink water only with great difficulty." This supports the idea that he suffered from hydrophobia, the fear of water. It was painful for Poe to swallow the water, and this suggests that he prefered to drink nothing. Severe Intoxication will not keep someone from being near water, nor can it cause intolerable pain when water is drunk, so his death must be something more than just a story of a belligerent drunk.
In the white matter area of the medulla oblongata contains ascending and descending nerve tracks which cross the brain and spinal cord. The protrusions in the white matter forms the pyramids with corticospinal nerve connect the cerebrum with spinal cord which controls the movement of voluntary muscles. These nerve tracks cross the left side to the right side of the body. The medulla regulates the force and heart rate through the cardiovascular system and medullary rhythmic area of respiratory center controls the respiratory processes. Other functions are controlling reflexes for vomiting, swallowing, sneezing and coughing and hiccupping.
Deep to the capsule is a network of reticular fibres and fibroblasts which, with the capsule and trabeculae, make up the stroma. Lymph flow through the node is one-way, entering through several afferent vessels on the convex side of the node’s ‘bean shape’ which contain valves opening toward the node’s centre, directing lymph into the node. Lymph then flows through three sinuses, irregular channels containing branching reticular fibres, lymphocytes, and macrophages, first the subcapsular sinus, immediately beneath the capsule, then the trabecular sinuses extending through the cortex parallel to the trabeculae, and then into the medullary sinuses. All sinuses filter the
They are laid out and protected by the ribcage, the chest bone (sternum), and the muscles between the ribs and the diaphragm (that constitute a muscular partition between the chest and the abdominal cavity). The nostrils form the main exterior opening for the respiratory system and are the first section of the body’s airway. Nostrils are involved in the intake of air, that is, they bring air into the nose, where the air is warmed and humidified. The tiny hairs called cilia filters out dust and other particles present in the air and protects the nasal passage and other regions of the respiratory
There are home remedies to cure sunburn and make the skin look smooth. These remedies are simple and effective. Cool compress can be placed on sunburned skin. It can be used by taking a cool shower or bath. It will give the skin the much required coolness and remove heat.
b. Some treatments were useless as “Wearing a leather shoestring around your neck to cure a cough.” 3. Diseases are caused by bacteria, which is a single-celled organism. While many people think all bacteria is harmful, there are actually a lot of species of bacteria that are advantageous. 4.
Paragraph 1~ How are inhalants used? People can breathe in inhalants through their nose or mouth in a number of various ways. One method includes sniffing or snorting fumes from a container or dispenser. Glue bottles and Markers are commonly used for this method. A second technique is spraying aerosols such as computer cleaners directly into the nose or mouth.
The labia majora forms from the fatty tissues from the mons veneris. The female external genitalia have two labia majora. It is also known as the vulva outer lips. The labia majora is also covered in hair, it varies in shape, color and size among women. The labia minora are also known as the inner lips of the vulva.
Starch amylase testing was equally unsubstantial since the only amylase producing bacteria was ruled out after Gram staining. Unknown #10’s negative citrate test result was also unhelpful because E. coli is citrate negative and P. vulgaris is a variable citrate producer that can also be citrate negative. H2S production in the Kligler’s Iron Agar test ultimately proved that Unknown #10 was Proteus vulgaris. P. vulgaris is the only assigned bacteria that produces H2S, so when a black precipitate obscured the yellow butt of the Kligler’s Iron Agar slant, E. coli was ruled out. Not only did the H2S product confirmed that Unknown #10 was P. vulgaris, it confirmed P. vulgaris’ motility.
It reduces the size of the pores and reduces breakouts. Toner (Obagi) Toner helps to remove excess skin oil and any impurities left after you clean your face. The Toner available from Obagi offers gentle care without stripping your skin of vital moisture. It uses a proprietary blend of sage and witchhazel to tone
The pharynx is also part of the respiratory system and it is known as the throat in simpler words. It is a tube that leads to the stomach and lungs. The larynx has three main divisions the nasopharynx, oropharynx, and the laryngopharynx. The nasopharynx is where air passses, oropharynx is where food and air pass through, and lastly the laryngopharynx is also where the air and food pass through. Another part of the respiratory system is the larynx which is also known as the voice box.
The solution is made from a teaspoon of salt, Epsom if available, and warm water. The water needs to be warm enough that the salt dissolves after stirring it, but cool enough not to burn you. Once it’s mixed, you would use a bulb syringe or other appliance to administer the nasal rinse. • Hot Shower/Bath: There are many healing qualities to be discovered by taking a nice and relaxing shower or bath. Steam from the
