Respiratory complication is one of the common causes of death‚ and my grandfather passed away from aspiration pneumonia couple years ago. Although we inadvertently breath air for granted‚ I observed many patients who had a difficulty breathing like my grandfather while shadowing a physician in ICU. Some of them had a lung surgery‚ while others were able to recover from a minimally invasive procedure using bronchoscopy. Certainly‚ my interest towards this field might change as I encounter new physicians

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

Title: The Effect of Nicotine on the Heart Rate of the Lumbriculus Variegatus Introduction: Background- This lab is being done to demonstrate the effects of stimulants on the circulatory system of blackworms. In this lab‚ the stimulant we have chosen to use is Nicotine. A stimulant is an agent that causes increased activity‚ especially in the nervous or cardiovascular systems. In this lab‚ we will put blackworms into the Nicotine to look at the differences in pulse rates when compared to a control

The starting material for this lab was the dialyzed sample (stored at -20ᵒ C) from the previous lab. The CM sephadex resin (taken in a 50 mL tube) was already made swollen using Buffer C (20 mM HEPES‚ pH 7.9; 1 mM EDTA; 50 mM KCl). The dialyzed sample was thawed to the room temperature and gently poured over the resin. The tube was capped and kept on a rocker at room temperature for 1 hour. The tube was then centrifuged in a HS-4 rotor at 2500 rpm (1200g) for 5 minutes at 4ᵒ C. Supernatant was discarded

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

HUMAN PHYSIOLOGY REPORT DAPHNIA Aim The aim of this experiment is to investigate the effect of temperature and various substances on the heart beat of Daphnia‚ a water flea. Introduction Daphnia belongs to a group of small‚ freshwater crustaceans of the order Cladocera commonly called water fleas. They are very suitable for laboratory studies due to the nature of their transparent exoskeletons. Hence‚ it is possible to watch Daphnia hearts without dissecting them. Daphnia is ectothermic and

It is essential that nurses are able to recognise and assess symptoms of respiratory dysfunction to provide early‚ effective and appropriate interventions to improve patient outcomes. It is necessary for a nurse to have a comprehensive knowledge base of the anatomy and physiological process of a healthy functioning pulmonary system‚ in order to carry out a respiratory assessment (Jenkins

Purpose The purpose of this experiment was to become familiar with the electrocardiograph to help us determine the electrical activity of the heart. As well as‚ to observe how exercise and different body positions(conditions) can affect the activity of the heart. Introduction Trained professionals can look at the EKG tracing and determine if the heart is normal or if the heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread
