How things flow through the heart: • blood drains into the right atrium through the superior vena cava‚ inferior vena cava‚ and the coronary sinus (drains the heart muscle itself)→Right Ventricle→pulmonary semilunar valves→lungs→pulmonary veins→left atrium→bicuspid valve→left ventricle→aortic semilunar valve→systemic circuit. What the valves do: • Prevent backflow into the atria and ventricles‚ ensuring that blood only flows one way through the heart. what vessels bring blood to the heart and

Both the cardiovascular and respiratory system help each other by working together to make sure that the tissues of the body are getting the correct amount of oxygen so that they can help the body to work efficiently as possible. They also help to make sure that carbon dioxide is forced out. The cardiovascular and respiratory system start to work together when the oxygen from the surroundings/environment enter through the nose‚ this will start the process where the body will receive the oxygen.

Organism Physiology The course in which different kinds of living organisms are thought to have developed from earlier forms during the history of the earth is defined as Evolution. Many time organisms evolve due to environmental changes. To better understand evolution this paper will review a diagram of an organism and explain how the organism has evolved physiologically to become suited to fit its environment. Organism To understand the evolution of an organism it is important to understand

PET 3351 Exercise Physiology Second Exam Review (Fall 2012) Chapter IV: The Physiological Basis of Muscular Strength and Flexibility 1. Strength is operationally defined as the maximal force that can be exerted in a single effort. Using this definition‚ strength should be assessed using one repetition maximum (1 RM)‚ though we often estimate strength using tests that may involve multiple repetitions. 2. In strength training and rehabilitation‚ emphasis should be given to both the concentric

INTRODUCTION MECHANIZATION AND TRACTORIZATION Mechanization encompasses a wide range of technologies‚ using human and or motor power. Hence‚ mechanization involves the use of tools‚ implements and machines to improve the efficiency of human‚ time and labour. The areas of application include; land development‚ crop production‚ harvesting‚ storage and processing. Mechanization is said to provide human operators with machinery that assist them with the muscular requirements of work. It can also be used to

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
