The Mechanism of Carbon Dioxide and Oxygen Exchange in the Respiratory of Human
Title: the mechanism of carbon dioxide and oxygen exchange in the respiratory of human

Abstract
The purpose of the experiment is to determine gas exchange activity in the respiratory system of human. The first lab for comparing the room and breathe temperature was to understand the function of the nasal cavity where the gas passed after an inhalation. The second lab for changing of chest circumference and abdomen circumference between inspiration and expiration was to know how the air moved in and out. The third lab of level of time of bromothymol blue colour change between normal and exercise was to discover the change level of carbon dioxide in the blood between relaxed and exercise. The forth lab of change time of holding breath after deep breath and quick breath was to show level of carbon dioxide change in the blood after deep breath and quick breath. The fifth lab of measuring diameters of the balloon which was blew by normal and force exhalation was to get the vital volume and the vital capacity form the graph of lung volume vs. balloon diameter.

Introduction
The major function of the respiratory system is gas exchange between the external environment and an organism's circulatory system. In humans, this exchange facilitates oxygenation of the blood with a concomitant removal of carbon dioxide and other gaseous metabolic wastes from the circulation. As gas exchange occurs, the acid-base balance of the body is maintained as part of homeostasis. If proper ventilation is not maintained, two opposing conditions could occur: respiratory acidosis, a life threatening condition, and respiratory alkalosis (West, John B. 1993). That is why people need to understand their mechanism of gas exchange in their respiratory system.

Materials and methods
In the experiment, materials required were a stop watch, a measuring tape, a thermometer, two straws, 25mL of bromthymol blue, two beakers, a balloon, a meter stick, two metric rulers and a bathroom scale.

    The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed through the mouth and nostrils into the lungs. The gas then diffuses through the alveolar walls and into red blood cells (erythrocytes). Carbon dioxide carried back within red blood cells diffuses back through the alveolar walls and is exhaled out through the mouth.…

    In this experiment, several physiological parameters were observed in three patients before, during, and after moderate exercise. One of these parameters was the pulmonary airflow, which was recorded utilizing an Airflow Transducer. This device measures airflow using slight pressure differences created by the resistance of a screen inside the device. Pulmonary airflow is the rate of movement into and out of the lungs, and is directly proportional to the pressure difference of the intrapulmonary pressure and the atmospheric pressure, and inversely proportional to the resistance of the lungs (elasticity/diameter of air pathways).1 The BIOPAC program then can convert the airflow to volume of air moved. Pulmonary ventilation is the movement of air in and out of the lungs. A more specific measurement of pulmonary airflow is the minute respiratory volume, which measures how much air is moved into and out of the lungs in one minute (tidal volume*breaths per minute).2 Since both deal with a volume moved per time, they are synonymous, although the parameter is referred to as airflow in this report.15E…

    The main function of the respiratory system is gaseous exchange. This refers to the process of Oxygen and Carbon Dioxide moving between the lungs and blood. This occurs during gaseous exchange as the blood in the capillaries surrounding the alveoli has a lower oxygen concentration of Oxygen than the air in the alveoli which…

    Respiratory acidosis is an acid imbalance in the body caused by a problem related to breathing. In the lungs, oxygen from inhaled air is exchanged for carbon dioxide from the blood. This process takes place between the alveoli and the blood vessels that connect to them. When this exchange of oxygen for carbon dioxide is damaged, the excess carbon dioxide forms an acid in the blood. The condition can be dire with a sudden attack, or it can develop gradually as lung function deteriorates.…

    Gas and Solute Exchange

    Gaseous exchange is the process by which oxygen is taken in by the body for respiration and carbon dioxide, the waste product of respiration, is released. In humans the lungs are the organ used for gaseous exchange. When we breathe, air moves in and out of the body via our lungs. In the lungs, the air moves into the alveoli and oxygen diffuses into the blood stream. Carbon dioxide diffuses in the opposite direction, from the bloodstream and into the alveoli, where it’s then breathed out into the air. The action of breathing involves muscles contracting and relaxing, depending on whether we want to breathe in or out. Movement of air in and out of the lungs is called ventilation.…

    Lung Lab

    in this lab, I learned about lung capacity and CO2 production. Lung capacity simply means the maximum amount of air you can take into your lungs. Lung capacity and CO2 production closely relate to the respiratory system. The respiratory system is the system in which oxygen goes into your body and carbon dioxide comes out; In short it’s breathing. The structures involved in the respiratory system are mouth/nose, mucus/cilia, pharynx, larynx, bronchi, bronchioles, alveoli, pleura, and diaphragm. There functions are as followed: Air enters the body through the mouth or nose. The mucus moistens the air and traps inhaled particles of dust or smoke, the cilia sweeps the trapped particles and mucus away from the lungs. The pharynx serves as the passageway for both air and food. The larynx contains two highly elastic folds of tissue known as the vocal cords. The Bronchi is the passage way for air from the trachea to the lungs. Bronchioles are tiny branches from bronchi to alveoli. The Alveoli are tiny air sacs where gas exchange occurs. The pleura are sacs that enclose the lungs and create a partial vacuum. And lastly the Diaphragm is the large, flat muscle at the bottom of the chest cavity that helps with breathing.( http://informationbible.com/article-the-human-respiratory-system-238074.html) The diaphragm is a major part of inhalation and exhalation along with the pleura membrane. Inhalation and Exhalation is simply the breathing in and out of air and carbon dioxide, either through the nose or mouth. The diaphragm is involved in inhalation and exhalation because when you breath it contracts and moves downwards, it becomes flatter making the pressure go down because there is now more space for air. And with this space air goes into the nose or mouth filling the lungs with air. Gas exchange also occurs between the alveoli and capillaries. The capillaries are the smallest blood vessels contained in the body! They are so small, that blood cells are only…

    Respiratory System

    The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function. The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air. When something goes wrong with part of the respiratory system, such as an infection like pneumonia, it makes it harder for us to get the oxygen we need and to get rid of the waste product carbon dioxide. Common respiratory symptoms include breathlessness, cough, and chest pain.…

    Gaseous exchange surfaces

    • 3 Pages

    In humans the gas exchange system is known as the Respiratory system. The respiratory surface is the Alveoli located on Bronchial tubes inside of the lungs. The average human adult has about 600 million alveoli which comes together to form a surface area of over 100 metres squared. There is only 2 thin walls of epithelial cells on the alveoli so things can diffuse quite easily. Water diffuses into the alveoli to keep it moist. Oxygen dissolves in this blood before diffusing into the blood stream. The steep concentration gradient across the respiratory surface is maintained in two ways: by blood flow on one side and by air flow on the other side. This means oxygen can always diffuse down its concentration gradient from the air to the blood, while at the same time carbon dioxide can diffuse down its concentration gradient from the blood to the air. The sheer number of alveoli inside the lungs means that the surface area for diffusion to take place is huge. In humans, carbon dioxide waste is breathed out through the lungs. Ammonia produced from cells is converted to urea as it is much less toxic and is excreted through the kidneys.…

    Respiratory System

    The respiratory system (or ventilatory system) is the biological system that introduces respiratory gases to the interior and performs gas exchange. In humans and other mammals, the anatomical features of the respiratory system include airways, lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. This exchange process occurs in the alveolar region of the lungs.[1] Other animals, such as insects, have respiratory systems with very simple anatomical features, and in amphibians even the skin plays a vital role in gas exchange. Plants also have respiratory systems but the directionality of gas exchange can be opposite to that in animals. The respiratory system in plants also includes anatomical features such as holes on the undersides of leaves known as stomata.[2]…
