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

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

FROG MUSCLE PHYSIOLOGY 2) What was the smallest voltage required to produce max contraction? What proportion of the muscle fibers in the muscle do you think were contracting to produce this maximal response? Muscle fibers act in response to isolated stimuli in an all or none fashion. However‚ a muscle organ‚ such as the gastrocnemius muscle‚ is composed of many individual muscle fibers. It is known that all of the fibers in a muscle do not have the same threshold and that a stimulus applied to

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

Chemical and Environmental Effects on the Heart Introduction The heart is the centerpiece of the circulatory system‚ its muscular contractions allow for the timely delivery of essential gases and nutrients to virtually all cells of the body. The pressure created by the heart also plays a vital role in eliminating wastes through organs such as the kidney‚ thus the heart delivers and helps maintain nutrient and waste composition throughout the body. The heart‚ like all muscle cells‚ releases ionic

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

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
