Review Sheet 1 Results 1. Describe two variables that affect the rate of diffusion. Your answer: Two variables that affect the rate of diffusion are the MWCO membrane and the solute concentration. Increasing the membrane size and solute concentration will also increase the average diffusion rate. Decreasing the membrane size and solute concentration will reduce diffusion rates and can even prevent all diffusion. 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane

Skeletal Muscle Physiology Activity 1 1. Skeletal muscle fiber- long‚ cylindrical cell with multiple oval nuclei arranged just beneath the sarcolemma Motor unit- all of the muscle cells controlled by a single motor neuron Skeletal muscle twitch- a single stimulus-contraction-relaxation cycle in a skeletal muscle Electrical stimulus- uses an electrical current to cause a single muscle or a group of muscles to contract Latent period- the time between the stimulation of a muscle and the start

HB105: Introductory Physiology The Action of Enzymes Introduction An enzyme is located in all living cells‚ and is a complex protein molecules. These protein based molecule act as a catalyst. This is a compound that aids chemical reactions without its own structure and state being changed during the process. Catalysts speed up chemical reactions‚ changing substrates into specific produce. Without these enzymes life would not exist. Enzymes are fundamental to all living things as they speed up

Lab report As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse‚ blood pressure‚ respirations‚ hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail. Procedure * Explain the procedure to the patient and gain consent * Wash hands thoroughly following the hand wash technique to prevent the transfer of bacteria * Clean equipment e.g. blood pressure cuff

On 3-28-13 in Anatomy and Physiology I got to take part in dissecting a cow eye. My lab partner was . The purpose of dissecting the cow eye was to learn and familiarize the class with the structure of the eye and to locate structures. Materials used were the cow eye‚ scalpel‚ probe‚ tweezers‚ scissors‚ dissection tray‚ gloves‚ paperwork / book‚ paper towel‚ ourselves‚ and our lab partner. My data includes the checklist‚ lab sheets‚ drawing‚ picture‚ and my lab report. The first step

REVIEW SHEET EXERCISE 6 Cardiovascular Physiology NAME: LAB TIME/DATE: 1. Define each of the following terms: • autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to
