Invertebrate trachea

The pathway of air from inhaling to exhaling: Inhalation: the process by which air is drawn into the lungs a) The diaphragm is pulled down (contracts) b) The ribcage is pulled up c) The ribcage is pushed out d) The lungs inflate with air (like blowing up a latex balloon) Exhalation: the process by which air is pushed out of the lungs a) The lungs deflate (removing the air from a balloon) b) The

The pharynx is the superior dilated part of the alimentary tract that connects the nasal and oral cavities to the oesophagus. It is composed of nasopharynx, oropharynx and laryngopharynx. The nasopharynx is situated posterior to the nasal choanae, superior to the soft palate and communicates with the nasal cavity anteriorly. The oropharynx starts posterior to the base of tongue and inferior to the soft palate. It is bounded laterally by the palatoglossal and palatopharyngeal arches, and communicates

the beginning on the trachea. This is the part that is in charge of taking in the air and letting it back out again, and then the lower respiratory tract which is made up of the trachea and the lungs. There are four different layers that make up the trachea, these include the mucosa which is the in most layer. This consists of ciliated pseudostratified columnar epithelium tissue which contains goblet cells that secrete a tacky mucus that lines the walls of the inner trachea so that it catches any

opening of the mouth. They have skeletal muscles and sensory nerves that are useful in judging textures of food and temperature. The lips mark the boundaries between the skin of the face and the mucous membrane that lines the alimentary canal. The trachea is hollow tube that connects the larynx and the bronchi of the lungs. It provides airflow to and from the lungs for respiration. The lungs is where the air you inhale goes and it lets go of waste air like carbon dioxide. The diaphragm is a dome shaped

Insects transport gases throughout their bodies through a system of branching tubes called tracheae which then branch off into tiny fluid lined tubes called tracheoles. Gases, oxygen and carbon dioxide, enter and exit the tracheae through paired openings called spiracles. These spiracles have filtering devices such as fine hairs, which prevent tiny particles from clogging the gas exchange system. Spiracles also consist of valves that control the degree to which the spiracles are open. The gases

the larynx is an important structure in the respiratory system as during swallowing the epiglottis closes over the trachea preventing food/drink/mucus/saliva into the airways. Once swallowing is complete the epiglottis flap relaxes allowing air to flow freely into the lower section of the respiratory system through the multiple layers of c-shaped cartilage structure called the trachea. The c-shaped cartilage is to prevent the airways from collapsing. The

Standard: When observing a radiograph of the chest, specifically at the mediastinal outlines, the trachea should be centered but may be slightly to the right of the mid line. This happens because the trachea passes on the right side of the aorta. If the trachea is not generally centered, it is important to decipher if it because of rotation or pathology. Notice the width of the chest and heart. The heart should not be any larger than half the width of the chest. This is called the cardio-thoracic

humans. Panthers use their lungs to breathe in and out. The breathing starts at the nose and their mouth. It then, travels down to the back of their throat, into the trachea. The trachea is a long tube in the panther’s neck that goes all the way through their chest, that carries air out and into their lungs. After that, the trachea divides into smaller passages called bronchial tubes. Bronchial tubes, are the tubes that carry air into the lungs of the panthers. Then, the bronchioles end in balloon

throat, common colds, or any other respiratory illness that you use to breeze right through. Knowing everyday that this will affect you lifespan, shortening it. Imagine you had Tracheobronchomalacia. Tracheobronchomalacia is the collapse of the trachea and one or both of the bronchi. This occurs do to the softening of the cartilaginous rings. The collapse can be classified in many ways but the shape of the airway after they are affected can be classified as crescent, which is when one side of the

In health and social care there are a lot of procedures and precautions put into place so that accidents don’t occur, but no matter how careful organisations are with these kind of incidents there is no way really of preventing them. In health and social care a lot of risk assessments are taken to make sure the place is safe but obviously there is still a few things that are unstable or accidents like this wouldn’t occur. The staff’s duty then is to work out what happened and how to minimise the
