CAPACITY Lung capacities are combinations of specific lung volumes. The lung capacities are measurements of two or more volumes. The total lung capacity (TLC) is a measurement of the total amount of air that the lung can hold; normally it is 6 litters for adult male and 4.2 litters for an adult female. The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. The Residual Volume (RV) is the amount of gas remaining the lungs after a maximal

File: GeomB 2011 Answers 8.10.11 No Calculators: Updated: August 10‚ 2011 A concave polygon looks sort of like a vertex has been ’pushed in’ towards the inside of the polygon. A convex polygon has all the vertices of the polygon pointing outwards‚ away from the interior of the shape. Think of it as a ’bulging’ polygon. A regular polygon is a polygon which is equiangular (all angles are congruent) and equilateral (all sides have the same length). Regular polygons may be convex or star. (5

respire faster. Meaning- they need more oxygen and glucose and release more carbon dioxide. A faster breathing rate means that oxygen can be taken into the body at a faster rate and carbon dioxide can be released faster. Cardiac output = stroke volume x heart rate Effects of exercise: Ventilation – breathing Respire – release of energy from food/chemicals Anaerobic respiration … is release of glucose without using oxygen. This produces lactic acid. glucose = lactic acid

Surface Tension of Water I. Purpose How does adding soap to water change its surface tension? II. Background Adhesion is the bond between two substances of different makeups. In water‚ adhesion allows it to stick to other surfaces. Cohesion is the bond between two of the same substances. A hydrogen bond is a type of cohesion in water in which the hydrogen atoms of one water molecule being attracted to the oxygen atom of another water molecule. In water‚ each molecule in the middle is pulled
