Lab Report: Exercise 5: Cardiovascular Physiology Type the answers to the following questions into the document. Save the file as YourLastName_Ex5LabReport.rtf and submit for grading via the associated assignment link. Activity 1: Heart Sounds 1. What is the cardiac cycle? The cardiac cycle is one complete heart beat. During the cycle each atrium and ventricle will contract and relax once. THe contraction of the chamber is called systole and the relaxation is called diastole. The average

PHYSIOEX 3.0 EXERCISE 33: CARDIOVASCULAR DYNAMICS Objectives 1. To define the following: blood flow; viscosity; peripheral resistance; systole; diastole; end diastolic volume; end systolic volume; stroke volume; cardiac output. 2. To explore cardiovascular dynamics using an experimental setup to simulate a human body function. 3. To understand that heart and blood vessel functions are highly coordinated. 4. To comprehend that pressure differences provide the driving force that moves blood

Exercise 9: Renal System Physiology: Activity 3: Renal Response to Altered Blood Pressure Lab Report Pre-lab Quiz Results You scored 25% by answering 1 out of 4 questions correctly. 1. If all other variables are kept constant‚ how does the afferent arteriole radius affect the rate of glomerular filtration (select all that apply)? Your answer : b. A decreased afferent arteriole radius will increase the rate of glomerular filtration. Correct answer: c. An increased afferent arteriole radius will increase

Introduction Cardiovascular Dynamics and the Cardiovascular Physiology experiments both have multiple goals. The first experiment aims to understand how blood flow‚ pressure gradient‚ and resistance relate to one another. To understand this‚ resistance and contributing factors‚ such as vessel radius‚ viscosity‚ and vessel length must be studied. The effects of vessel radius and stroke volume on the ventricular pump should also examined. The experiment also calls for an understanding of cardiovascular compensation

Cardiovascular System Anatomy & Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac

Lab 34b Cardiovascular Physiology 1. What was the baseline heart rate for the frog? 59-63 bpm 2. Which wave is larger‚ the one for atrial contraction or the one for ventricular contraction? Why? Ventricular. It shows the strength of the ventricle as it pumps blood‚ and it is a thicker muscle to pump stronger as it contracts 3. At what time during the contraction cycle was it possible to induce an extrasystole? The time during the relaxation part of cardiac cycle. 4. By clicking the Multiple

The forest lake aquathon consists of a 250 meter swim and a 2.5 kilometre run. A specific training program has been made to improve my weaknesses and work on cardiovascular fitness and endurance. This essay will also evaluate the personal training program that has been created and whether or not it will help improve my fitness. In last year’s aquathon I did not participate‚ but the average time that most students finished were around 20 minutes. There was also a fitness test where students swum

Terms | Definitions | Explan why the larger waves seen on the oscilloscope represent ventricular contraction | the ventricle contraction is of greater force than the atrial contraction‚ this is due to the fact that ventricle’s fxn is to send blood throughout the body. | Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation in cardiac muscle. | amplitude does not change because the cardiacs long refractory period prevents summation. | Why is
