CARDIOVASCULAR FITNESS CARDIOVASCULAR fitness is the fitness of the heart‚ blood and blood vessels. “Cardiac” is another word for heart‚ and “vascular” refers to blood vessels. Of all the parts of fitness‚ this part is one of the best for helping you feel good and enjoy life more and to reduce stress. Cardiovascular fitness helps you look good because the exercises you do to maintain your fitness help you control your weight and develop a good physique (figure) and increases your self-esteem.

Introduction: Every muscle has lactic acid.According to many people Lactic acid is nasty stuff produced in our muscles during exercise‚ cause soreness‚ muscle fatigue‚ does not contribute to exercise performance‚ muscle does not use it for fuel‚ and better athletes makes less of it. But they all are wrong or in other words they are a lay. Instead Lactate acid is made of Lactate ion called (Lactate) and Hydrogen Ion. C3H6O3----->C3H5O3++H- C2H3OHCOOH--------->C2H3OHCOO+ +H- Hydrogen ion is the acid

voltage the muscle has contracted as much as it possibly will. 5. An individual muscle fiber follows the all-or-none principle—it will either contract 100% or not at all. Does the muscle we are working with exhibit the all-or-none principle? Why or why not? No‚ because it will contract and then relax if needed or to get accustomed Multiple Stimulus Activity 4: Treppe 1. What do you observe? The peak rose higher each time Activity 5: Summation 1. What is the active force of the contraction

Homework #4 Name _______________ Lab Day/Time____________ Cardiovascular Dynamics This experiment examines the factors that effect blood flow through a blood vessel. The rate of blood flow is influenced by the pressure gradient in the vessel‚ the radius of the vessel‚ the viscosity of the blood and the length of the vessel. You will be asked to systematically examine each of these factors to determine their effect on blood flow. Getting Started: Login to a CAL lab computer using ZULU

ACTIVITY 5 Exploring Various Breathing Patterns You will establish the baseline respiratory values in the first part of this experiment. 1. If the grid in the data control unit is not empty‚ click Clear Table to discard all previous data. 2. Adjust the radius of the airways to 5.00 mm by clicking the appropriate button next to the Radius window. Now‚ read through steps 3–5 before attempting to execute them. 3. Click Start‚ and notice that it changes to Stop to allow you to stop the respiration. Watch

ACTIVITY ONE- Cell Transport Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse. Membrane size is another variable that affects the rate of diffusion because if the membrane’s pores are small it will take molecules longer to diffuse though it than if the pores were larger. Also‚ membrane thickness

Cardiovascular Diseases Cardiovascular disease is defined as a disease that affects any area of the cardiovascular system‚ including the heart and blood vessels‚ and covers a range of diseases such as arteriosclerosis‚ atherosclerosis and coronary heart disease. Diet plays a vital part in the prevention and control of these diseases however other manageable factors such as smoking and physical inactivity also contribute to the diseases if not controlled correctly. However corrective action or
