Maria Martinez Anatomy and physiology II TTH 2:20 “Demonstrating the Importance of Surfactant: Lab Report” Introduction Surfactant is an essential component for the respiratory system to function properly. This experiment was administrated to help us understand better the role of surfactant in the alveolar system. Surfactant is a detergent-like substance produced by the Type II alveolar cells in the alveoli. Surfactant is produced to make it easier for people to breath by reducing the surface

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

typically permits the membrane potential to reach the threshold potential at which it fires the next action potential (pacemaker potential). Thus‚ the pacemaker potential is what drives the self-generated rhythmic firing. This is known as cardiac muscle automaticity.[2] Pacemaker potentials are fired by sinoatrial node (SAN)‚ but also by the other foci. However‚ the last ones have firing frequencies slower than the SAN’s. When other foci attempt to fire at their intrinsic rate‚ they can’t because they

Introduction to Human Skeletal System: Skeletal system is the system of bones‚ associated cartilages and joints of human body. Together these structures form the human skeleton. Skeleton can be defined as the hard framework of human body around which the entire body is built. Almost all the hard parts of human body are components of human skeletal system. Joints are very important because they make the hard and rigid skeleton allow different types of movements at different locations. If the skeleton

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask

EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic
