Interpretation Trends less commonly included Although the order that these sections are placed on a report will vary a lot from one Pulmonary Function Lab to another, demographics will always be first. At the very least the demographics section of your report should include: Your normal values will be based on your gender, age, height and race or ethnicity.
Zurus Siddiqui The Respiratory System Introduction Cells in the body require oxygen to survive and the body requires a continuous supply of oxygen to carry out its vital functions. The respiratory system exchanges gases through the alveoli in the lung and distributes oxygen through the cardiovascular systemic circuit to the different parts of the body and their tissues.
Thus the cardiovascular system and respiratory system work hand in hand. In this lab, we learned about the anatomy of the respiratory system as well as how the lungs mechanically function by using a lung model.
In the second part of the lab, we used a lung model to demonstrate the principles of gas flow into and out of the lung.
Results- To begin this lab, we examined the upper respiratory system structures, including the nose, pharynx and larynx. Air enters the respiratory tract through the nostrils or nares, and into the nasal cavity.
This space in the nose is divided by the nasal septum. As air flows into the body, it goes over the inferior, superior and middle nasal conchae, three pair of lobe- like structures, increasing the air turbulence, the air is warmed, moistened, and filtered by nasal mucosa.
Four sinuses, the Frontal, Sphenoid, Ethnocide and Maxillary Bones, act as resonance chamber in speech. These four cavities also warm and moisten the incoming air.
Although close to the oral cavity, the nasal passages are separated from it by the hard and soft palate. Air can also enter the respiratory tract through the mouth and then into the pharynx, a funnel- shaped structure, commonly called the throat.
It is the pharynx that connects the nasal and oral cavities to the larynx, as well as the esophagus. The pharynx is divided into three named parts: Laryngopharynx The superior portion is the nasopharynx, and is posterior to the nasal cavity. It is continuous with the posterior nasal aperture and passes air only.
The nasopharynx also Nasal Cavity hold the pharyngeal tonsil, the pharyngotympanic or auditory tubes, and the tubal tonsils.
Posterior to that is the oropharynx, which extends from the soft palate to the epiglottis. This area serves as a conduit for food and air.
In its walls are the palatine tonsils and lingual tonsil. Lastly, the laryngopharynx is also a common passageway for food and air. It extends from the epiglottis to the larynx.
From there, the passageway for the digestive and respiratory system divided into the trachea and esophagus. The epiglottis is made of a more flexible elastic cartilage than the hyaline cartilage of the larynx.
Instead, these substance go into the esophagus, or food chute. Each group member felt their own larynx by palpating the neck. As we swallowed, we could will the cartilaginous structure rising. The mucous membrane of the larynx is made up of two folds: The upper vestibular folds or false vocal cords II.
The lower vocal folds or true vocal cords. Larynx These vocal cords are used for speech as they vibrate when air is expelled against them. The vocal cords attach to the arytenoid cartilage with vocal ligaments. The area of the vocal folds and the passageway between them is called the glottis.
Next, we moved onto the lower respiratory structures. This began with Trachea, or windpipe, in which the larynx travels down until the sternal angle. This is approximately around the fourth or fifth thoracic vertebrae, from there, the air passageway divides into right and left main, or primary Bronchi.
Through the hilum, they enter their respective lungs. We noted that the right main bronchus is wider, shorter, and move vertical than the one of the left.
The trachea is lined with cilia that propel any mucus that has encountered dust particles or bacteria towards the throat. That way the foreign substance can be coughed out or swallowed. As the main bronchi continue on, they further divided into smaller and smaller branches until they are structures called Bronchioles.
As the branches decrease in size, the amount of smooth muscle increases and the cartilage diminishes.This essay discusses an analysis of Respiratory physiology.
In light of this significance, three experiments which are discussed in this report were conducted in order to assess the factors which affect the respiratory rate and interpret the findings and compare them. 1 BioLab 3 Respiratory System Lab Report I.

Abstract Pulmonary function is an integral part of the physiology of the human body. It plays an important role in gas exchange and arterial gas concentrations.
Lab Report 6: Respiratory Physiology Purpose: To describe the effects of carbon dioxide concentration on blood pH. Hypothesis: If the blood CO2 levels increase, the pH will decrease.
