To develop techniques of using a portable spirometer.
Problem statement:
Can vital capacity and total lung capacity be measured by Spiropet?
How gender can affect the vital capacity and total lung capacity of human lungs?
Abstract:
The main objective of this experiment is to measure the vital capacity (VC) and total lung capacity (TLC) of people of different gender. The main methods used in this investigation can be divided into two parts, namely investigation on VC and investigation on TLC. The main method used for investigation of VC is by exhaling the maximum volume of air inhaled into the spirometer. The reading from the spirometer is then recorded. The main method for TLC is by inhaling the maximum volume of air, followed by normal exhalation. The remaining volume of air inside the lungs is forced into the spirometer. The reading of the spirometer is then multiplied by 6 to obtain TLC. The main results from this experiment is that the both the VC and TLC are higher in male students than females. Therefore, from this experiment, we can conclude that the VC and TLC of men are generally greater than women.

The respirometer uses the principle of water displacement. As the amount of gas in the respirometer changes, this will be reflected by an equivalent displacement of water in the pipette. Remember that at the same temperature and pressure,...
I only chose respiratory as an answer. However, the correct answers are respiratory and cardiovascular because of the pulmonary circulatory system. Gas exchange occurs at pulmonary capillary beds.
Ascertaining the adequacy of gaseous exchange is the major purpose of the respiratory assessment. The components of respiratory assessment comprises of rate, rhythm, quality of breathing, degree of effort, cough, skin colour, deformities and mental status (Moore, 2007). RR is a primary indicator among other components that assists health professionals to record the baseline findings of current ventilatory functions and to identify physiological respiratory deterioration. For instance, increased RR (tachypnoea) and tidal volume indicate the body’s attempt to correct hypoxaemia and hypercapnia (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). The inclusive use of a respiratory assessment on a patient could lead to numerous potential benefits. Firstly, initial findings of respiratory assessment reveals baseline data of patient’s respiratory functions. Secondly, if the patient is on respiratory medication such as salbutamol and ipratropium bromide, the respiratory assessment enables nurses to measure the effectiveness of medications and patient’s compliance towards those medications (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). Thirdly, it facilitates early identification of respiratory complications and it has the potential to reduce the risk of significant clinical
Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p. 430). During inhalation, the lungs expand with air, similar to filling a balloon. The pliable latex of the balloon allows it to expand, just as the pliability of lungs and their components allows for expansion. During exhalation, the volume of air decrease causing a deflation, similar to letting air out of the balloon. However, unlike a balloon, the paired lungs are not filled with empty spaces; the bronchi enter the lungs and subdivide progressively smaller into bronchioles, a network of conducting passageways leading to the alveoli (Marieb, 2006, p. 433). Alveoli are small air sacs in the respiratory zone. The respiratory zone also consists of bronchioles and alveolar ducts, and is responsible for the exchange of oxygen and carbon dioxide (Marieb, 2006, p. 433).
Aim: The aim of this assignment will be to research the basic structure and function of Human Lungs and the respiratory condition known as asthma, and how its effects on the human lungs, looking at the causes and treatments used to prevent and treat the illness.
The skeleton of the respiratory system is important for keeping the organs and structures safe. The skeleton is the spinal column, pelvic girdle, the rib cage, the clavicles, the scapulae, and the skull. The skeleton of the respiratory system and the soft tissues allow the muscles of the respiratory system to move gasses in and out of the lungs and respiratory passages. Bringing air and gas into the system is called inspiration while forcing out gas and air is expiration. One of the primary muscles of inspiration is the diaphragm. It is located right under the lungs and when it contracts, it flattens part of the thorax which flattens the abdomen and makes the lungs larger. That is why it is called diaphragmatic or abdominal movement. Changing the dimensions of the thoracic cavity with several other muscles by acting on the ribs is called costal movement. “Pump Handle Movement” shifts the thorax up and forward by movement of ribs one through six. The other is called “Bucket Handle Movement” which shifts up and laterally by movement of ribs seven through ten. Intercostal muscles allow the ribs to move in that way. Primary muscles are used for normal
Observing the charts below you will notice Dr. Burt continuously had a higher VO2/kg average. Men generally will have a higher VO2 max due to increased thoracic cavity size, thus allowing for more oxygen uptake. While being a male put Dr. Staniar at an advantage for a higher VO2 max, being above the age of 40 but him at a disadvantage. As we get older VO2 max will decrease because of a reduced maximum heart rate and stroke volume. While maintaining exercise and staying fit will not affect maximum heart rate it will alter stroke volume positively in some degree. The average VO2 max for men per year is 0.46 ml/kg/min and for women is 0.54 ml/kg/min. A true plateau is never seen in the graphs. This could be due to experimental error or neither participant truly never reaching maximal oxygen uptake due to experiencing discomfort
Women tend to have more symptoms such as shortness of breath and more difficulty exercising than men
The experiment consisted of a BIOPAC MP3X unit that was prepared with a Respiratory Transducer plug that was placed around the chest below the armpits and above the nipples, the respiratory transducer must be slightly tight. Three electrode lead sets were placed on the subject’s right ulna artery just above the wrist, right posterior tibial artery just above the ankle bone, and left posterior tibial artery just above the ankle bone. EDA plugs were then placed on the subject’s finger tips of their index finger and third finger. The subject was then sat in a chair facing the director, with arms relaxed at the side of the body, and hands a part In lap, with legs flexed at knee and feet supported. A baseline was then recorded for the first subjects,
When you breathe in, air containing carbon dioxide (CO2) and oxygen (O2) it moves down your trachea; a tunnel containing cartilage and smooth tissue. Air then travels through two hollow tubes called bronchi; narrow branches lined with smooth muscle, mucosal and ringed cartilage to support the structure. The bronchi divide out into smaller tunnels called bronchioles; are small branches 0.5-1mm, lined with muscular walls to help dilate and constrict the airway. At the end of the bronchioles are little air sacs called alveoli; which assist in gas exchange of O2 and CO2. (Eldridge, 2016) Towards the end of alveoli are small blood vessel capillaries. O2 is moved through the blood stream through theses small blood vessels (capillaries) at the end of the alveoli and the CO2 is then exhaled. (RolandMedically,

Air pressure in the lungs rises to just above atmospheric pressure, therefore the air is expelled. Regulation of breathing is controlled by the respiratory centre in the the hind brain. The respiratory centre has three areas called the medullary rhythmic area, the apneustic area and the pneumotaxic. area. The sand is a sand.
The ANS is positioned just below the medulla oblongata in the lower brainstem. The medulla is responsible for many major functions, such as respiration, cardiac regulation, vasomotor activity, and reflex actions; which include coughing, sneezing, vomiting, and swallowing. The input is received by the hypothalamus, which is located right above the
