Lung volumes

Lab two explored varies ways to find the density of objects. This lab used displacement , measurement, and the density formula to make observation and collect data about the balloon filled with sublimed dry ice, various water samples, and a golf ball. The ultimate goals of this experiment were to collect the most precise measurements of displacement of the balloon in the tap water, the weight of the three water samples versus the original cylinder, and diameter of the golf ball in order to use…

opposite process was used to determine the calibration of a piece of glassware using a known density. In the first activity, “Density of Liquids”, the identity of a liquid was determined by calculating its density (g/mL). First the mass (g) of a specific volume (mL) of water and the unknown liquid was found. Their densities (g/mL) were then calculated by dividing the mass (g) by the density), the calculated density was then compared to a list of known densities to determine the liquid’s…

by measuring their mass and volume. A decigram balance is used to measure the mass of the substances, and a cylinder is used to determine their volume. The major result of this experiment is that by measuring the mass and volume of the unknown solid and liquid, the density can be calculated easily and accurately. Introduction The density of a given amount of substance is depended on its mass and volume. Density also varies when temperature changes because the volume will change when temperature…

Density is a physical property of matter, it is used to describe the degree of compactness in a substance, or how closely packed a substance’s particles are. Density is a ratio of a substance’s mass and volume, therefore, the density of a substance can be found by dividing it’s mass by it’s volume. Density id relatively unique to each substance, while densities of certain substance’s may be similar, the densities are still distinctive enough to act as an identifier for it’s substance. The…

Overview The standards that are being used in our lesson are the ideas that matter exists in three states solids, liquids, and gas and objects can be measured based on the size, weight, or texture. This is most important to our lesson as it discusses volume and matter in different aspects. The penny drop experiment has many underlying advances to understanding the big question: how do scientists work together to solve problems? Just like filling a cookie just enough to not overfill but also a…

Gaseous exchange Breathing is the body’s way of exchanging oxygen for carbon dioxide. The lungs get oxygen through alveoli. The air is transported though the trachea and diverted though the bronchi into a lung, the bronchi extends into smaller tubes called bronchioles witch at the end of them are little air sacks (the alveoli). Oxygen is needed to get into the blood stream to allow oxygen to be supplied throughout the body in order for it to function normally. It does this by gaseous exchange.…

respiratory system of how breathing rates affects the tidal volume, expiratory reserve volume, inspiratory reserve volume, residual volume, vital capacity, total lung capacity, forced vital capacity, and forced expiratory volume in one second by using spirometry. The respiratory system is organs taking the oxygen and releasing the oxygen out of the body. Pulmonary function tests measure the lungs if it is working well or not by measure lung size and air flow to see how oxygen flow in and out of…

intrapulmonary pressure, atmospheric pressure and airflow within the lungs. “Intrapulmonary pressure is the pressure within the lungs, atmospheric pressure is the pressure used in all directions at any given point by the weight of the atmosphere and air flow is simply the motion of air. Intrapulmonary pressure and atmospheric pressure are usually measured in units of millimeters of mercury. “Inspiration is the act of drawing air into the lungs and expiration is the exhalation of breath…

The total lung capacity refers to the maximum amount of air a person’s lungs can hold (wisegeek.org, 2014). Breathing occurs in a cyclic manner due to the movements of the chest wall and the lungs. The resulting changes in pressure, causing changes in lung volume and lung capacity (humanphysiology.hubpages.com, 2014). An average human’s lung capacity can hold 4-6 liters, but only ⅓ of your lung capacity is used during normal activity, but this fraction increases during strenuous activity when…

It test how well you inhale and exhale, and it also test how much air your lungs take in with each breath. To perform this test, an instrument called a spirometer is used which measures the volume of air moving in and out of the lungs during pulmonary ventilation. When given this test a person can be standing up or sitting down but whichever one that person must remain in that position throughout the whole test. The person cannot change positions because that will mess of the results from the…
