📝 Name of Specimen: Larynx, section
🔬 Objective/s Used: Low-Power Objective
📚 Description: The larynx is characterized by being a hollow tube found in the middle of an individual’s neck (Cleveland Clinic, n.d.). It is situated only above the trachea and the esophagus. The larynx’ job is to let air pass through from the throat, down to the trachea, and into the respective lungs. Through the presence of the larynx, it also allows humans to make sounds, that is why it is referred to as the voice box.📝 Name of Specimen: Trachea Mammal, c.s.
🔬 Objective/s Used: Low-Power Objective
📚 Description: A tube structure that is found in the neck and upper chest of mammal is the trachea, which is an essential component for airways (Fletcher, 2024). The trachea functions by ensuring that the carbon dioxide mammals exhale will go out the body, while the oxygen taken should enter the lungs. In simple words, the trachea of mammals provides an avenue for air to move to and from the lungs during breathing commences.📝 Name of Specimen: Frog Lung, x.s.
🔬 Objective/s Used: Low-Power Objective
📚 Description: Describing the lung of a frog is like looking at of those a human. The frog of a lung allows for efficient gas exchange. More to it, it happens when the expandable lung tissue inflates when the frog inhales, which allows for the transfer of oxygen into the frog’s bloodstream (Malone, 2021). On the other hand, via the lung of a frog, carbon dioxide from the bloodstream diffuses back into the lungs and is expelled into the frog’s body when exhalation happens.📝 Name of Specimen: Bronchiole, c.s.
🔬 Objective/s Used: Low-Power Objective
📚 Description: Bronchioles are characterized by being tiny tube structures that split off from the bigger bronchi. Their primary role is to direct the airflow toward the alveolar ducts, and as such termed as being the tiniest airways that are found in the respiratory system (Biology Dictionary, 2017). Additionally, the bronchioles are vital for it aids in efficient gas exchange that occurs in mammals.References:
