Lab 8: Isopentyl Acetate CHM 2211L October 22‚ 2014 Abstract Many esters are naturally occurring compounds that are responsible for the fragrance of fruits and flowers. Isopentyl Acetate is the compound responsible for the smell of bananas. However‚ when Isopentyl acetate is treated with H3O+ it will hydrolyze back into the carboxylic acid‚ which will change the fragrance. In this experiment 3.11g of Isopentyl Acetate were produced with a 51.92 percent yield. Introduction Esters are carboxylic

Physiology Assignment Physiology Assignment Short term responses One short term response when playing basketball is when your face starts to go red‚ this happens because the body gets too hot and it tries to cool the body down by bringing blood to the surface of the skin to let some heat out and the skin also produces sweat to let out heat‚ therefore the skin surface goes red. Another short term response to physical activity is that your breathing rate and heart rate increases‚ the reason

Lab Report One Exercise Five Activity One “Simulating Simple Diffusion” Activity Two “Simulating Facilitated Diffusion” Jessica Ogola Anatomy and Physiology 2401 Dr. Denyse Jones 02/02/2012 Objective: The objective of this experiment is to perform the simulation of the movement of solutes from a higher concentration to a lower concentration within a given amount of time. The goal of the exercise is to provide a simulation for the process of the facilitated diffusion of

The Cardiovascular System David Clarke is 30 years old‚ stands 6’ and weights 225 lbs. He commutes between Miami where he is a full time student‚ and Hialeah‚ where he works as a paramedic. He sleeps only two to four hours per night. Brian is overweight and does very little exercise. He also admits to eating mostly fatty foods. Both David’s grandmother and father have suffered heart attacks. According to new statistics‚ “despite the recent decline in mortality from coronary heart disease‚ this disease
Premium Heart Blood
Cardiovascular The cardiovascular system is consists of the heart and network of arteries‚ veins‚ and capillaries that transport blood throughout the body. There are two primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it
Premium Heart Cardiology
The Cardiovascular System The cardiovascular system consists of a heart and an enclosed system of blood vessels categories into arteries‚ capillaries and veins. The heart is a muscle about the size of the fist; its wall is made up of a muscle known as the Cardiac Muscle‚ and is located between the two lungs and lies left of the middle of the chest (cliff notes). A fibrous covering known as the pericardium which surrounds around the whole heart holds the heart in place but allows it to move as

Erythrocytes Survive 120 Days Hemoglobin * Globin: 4 folded polypeptide chains * Heme: Iron group in each polypeptide that binds 02 Enzymes: * Glycolytic: generate energy through glycolysis due to lack of mitochondria * Carbonic anhydrase: for transport of CO2 into HCO3 Erythropoiesis: * regeneration of new cells in the bone marrow Erythropoietin (hormone): * when kidneys detect not enough 02 they secrete this hormone which stimulates erythropoiesis‚ increasing 02 capacity

Equipment Calibration is defined as the act of adjusting and evaluating the precision and accuracy of measured equipment. It allows the user to get an accurate and precise reading of measurements to its actual true value. However‚ in order for the experiment to be effective is must consist of validity‚ reliability‚ and objectivity. Validity is defined as the ability of a test to measure what it claims to measure. Reliability is the consistency of test results and objectivity is defined as a test

Cardiovascular Dynamics Vessel Resistance Key Terms: 1. Blood flow- the amount of blood moving through a body area or the entire cardiovascular system in a given amount of time. 2. Pheriphial resistance- the opposition to blood flow resulting from the friction developed as blood streams through blood vessels. 3. Viscosity- A measure of the “thickness” of the blood and is caused by the presence of proteins and formed elements in the plasma 4. Systole 5. Diastole 6. End diastolic volume

1. Why do we need a cardiovascular system? Because we need to get oxygen through our system. 2. Make sure you know which circuits the left and right heart pump into (pulmonary or systemic). Also know the status of blood (fully oxygenated or not) at -the aorta: Left‚systematic‚ and fully oxygenated. -a pulmonary vein: Left side‚ pulmonary‚ and fully oxygenated. Goes from the right side of the body(heart) into the (left) pulmonary veins then goes to the left atrium then to the left ventricle then
