Nasal cavity

The length of the nasal cavity, molar toothrow and skull length (max.) was measured in the three individuals from each species using calipers and rulers (in centimeters); these three measurements of individuals for each species serve as replicates (12 replicates in total). The type of diet of the species is the independent variable while the length of the nasal cavity and molar tooth row is the dependent variable. The data was standardized by dividing the length of the nasal cavity/ tooth row by the

respiratory system as my body system. It removes the carbon dioxide from the body whilst providing the body with the oxygen that it needs. There are 5 main key processes that the respiratory system control. They are: Breathing - moving air through the nasal cavity to the lungs and back out. It is also called ventilation. External respiration - gases within the air and in the blood exchange between each other. Gas transport by blood - the cells of the body receive oxygen and transport it around the body

The respiratory system is a series of organs in which is responsible for taking in oxygen and releasing carbon dioxide. The main organ in the respiratory is the lungs which helps with the prosses of exchanging gases as we breath. Red blood cells collect and use the oxygen to carry around the body to parts that need it. The body needs oxygen to survive because when without it, it would be fatal which is why the respiratory system is important. The respiratory system is dependent upon other organ

The nose and the nasal cavity form the main external opening for air to come through. The air that comes through is warmed and filtered by the mucus. The mouth is the secondary external opening for the respiratory tract. It does not have the hair and sticky mucus that filter air passing through the nasal cavity but its shorter distance and bigger space allows more air to quickly enter the body. The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane

particles and vapors. When the cigarette smoke enters the nose, to the nasal cavity, paranasal sinus, into the larnyx, esophagus and onward through the body. I want to stop and go back to the beginning of smoke entry. The nose contains external nears or cilia. These cilia try to capture as much of these toxic particles and push them back towards the outside of the nose. Then these toxic particles move through the nasal cavity, up and around the paranasal sinuses, which contains the frontal, esthmoid

The breathing process is a result of the respiratory system. The breathing process starts when we take in oxygen from the air through our nasal or oral cavities. From our nasal or oral cavities oxygen moves through the pharynx, larynx, and trachea into the lungs. There oxygen reaches red blood cells where it is then distributed to the cells in the body. In the alveoli through a process called external respiration

Respiration and Circulation Name Description and function Nasal cavities The nasal cavity is an air filled space found behind the nose. Air is breathed in through the nose, which is divided by the septum to form the nostrils. The septum is mainly made of cartilage. Within the nose there are small hair like structures called cilia, which stop foreign particles from being inhaled by filtering them out of the air before it continues through the system. The nose contains mucous membranes which produce

system is divided in two different tracks, upper tract including nose, nasal cavity, sinuses, and pharynx; Lower respiratory tract includes larynx, trachea, bronchial tree, and lungs. The system served the main purpose of transporting air into the lungs, and flows from the top to bottom. Nose is a convex feature lays in between and under our eyes, structured with bones, muscles, and flexible tissues named cartilage; with long thin nasal bones supporting the nose structure. Nostrils on nose are pathways

FACILITATES GAS EXCHANGE? The most vital phenomenon of life is respiration. Without respiration life is impossible. Respiratory System, consisting of a number of organs in human body which is taking the function of respiration. These organs include mouth, nasal passage, glottis, trachea, larynx, pharynx, bronchi, bronchioles, alveoli and last but not the least the LUNGS. Other supporting orangs are ribs, intercostal muscles, diagram and cilia. In the following lines, we’ll discuss in detail about these organs
