The Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic cardiac______ cells that initiate and distribute __impulses___ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of _heart depolarization___. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA Node __initiates the depolarizing

Introduction The experiment aimed to establish a correlation between caffeine intake and the effects it has on both the pulse and respiration rates of an individual after undergoing moderate-intense cardiovascular exercise. Caffeine itself is one of the most heavily consumed drugs on the planet; it is estimated that over 90% of Americans consume caffeine daily (Richard Lovett‚ 2005‚ New Scientist iss. 2518) and is the most widely used stimulant in the world (Arcerio‚ P‚ Ormsbee‚ J‚ 2009‚ pg. 1)

ANATOMY AND PHYSIOLOGY OF THE HEART Anatomy: The heart and heart wall layers: The heart is located in the left side of the mediastinum; it consists of three muscle layers the Endocardium‚ myocardium‚ and epicardium. The epicardium is the outermost layer of the heart. The myocardium is the idle layer of and actual contracting muscle of the heart. The endocardium is the innermost layer and lines the inner chambers and heart valves. Pericardial sac: The pericardial sac encases and protects

M1. Discuss the role of energy in the body The three systems in our body that work together are cardiovascular‚ respiratory and digestive systems which supply energy to the cells of the body. I will be describing their role of energy in the body system; also I am going to explain the physiology of the three named body systems in relation to energy metabolism. Respiratory System The respiratory system consists of tissues and organs in our body which are formed into groups. The system includes airways

This assignment will describe the role of energy in the body and explain the physiology of two named body system in relation to energy metabolism. It will explain where energy comes from‚ how the body uses energy‚ what is metabolism/catabolism and anabolism and also it will explain cellular respiration aerobic/anaerobic is. Energy is necessary for muscular activity and movement however‚ energy is also necessary to circulate blood and lymph and tissue fluid throughout the body; for breathing and

THE ORGANISATION OF THE HUMAN BODY By Rachel Bull CELLS The organelles of cells and their function • Cell (or plasma) membrane - The plasma membrane acts as a boundary and controls what substances can enter and exit the cell. • Cytoplasm - This semi-fluid substance found inside the boundary of the cell and outside the nucleus cushions and protects the internal organelles‚ this is also where the majority of the chemical reactions happen. • Nucleus - The nucleus is the double-membraned central
