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

Lab Title: Microscopy Objective: To learn how to use and care for a microscope and to know the parts of a compound microscope and to efficiently use the microscope to focus on specimen. Introduction A microscope is an optical instrument used for viewing very small objects‚ typically magnified several hundred times. It consist of different lenses such as: Scanning = 4X‚ Low power = 10X‚ High power = 40 or 43X‚ Oil Immersion = 100X. A microscope is an instrument

ANATOMY AND PHYSIOLOGY OF HUMAN HEART The human heart is a cone shape‚ hollow‚ muscular organ located in the mediastinum between the lungs. It is a about the size of an adult fist. The heart rests on the diaphragm‚ tilting forward and to the left in the client’s chest. Each beat of the heart pumps about 60ml of blood‚ or 5L/min. During strenuous physical activity‚ the heart can double the amount of blood pumped to meet the increased oxygen needs of the peripheral tissues. ANTERIOR VIEW

Human Physiology Lab Special Senses Cutaneous Senses and Vision September 24/26‚ 2012 Our bodies are capable of sensing a wide spectrum of stimuli. We are consciously aware of some of the information our bodies perceive‚ but much of the information that is sensed is beyond our consciousness. Receptors responsible for perception of stimuli are found in many places: skin‚ eyes‚ ears‚ mouth‚ blood vessels‚ lungs‚ brain—frankly‚ every cell in the body has sensory receptors. These receptors are

membrane size and solute concentration will reduce diffusion rates and can even prevent all diffusion. 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? Your answer: The urea was not able to diffuse through the 20 MWCO membrane because the molecular weight was too high. For a molecular weight of 60.07‚ a larger membrane would need to be used. The results opposed my prediction because the urea did not diffuse at

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Anatomy is the study of the structure and shape of body and parts‚ while physiology is the study of how the body work and function‚ their relationship is seen for example in the heart‚ there are two valves (anatomy) and these two valves help the heart pump blood. 2. The atom is the smallest particle of an element. An example is carbon ( C ) which is the building block of life. A group of atoms could form for example‚ a water molecule

ANATOMY AND PHYSIOLOGY OF THE RESPIRATORY SYSTEM The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. Respiration is achieved through the mouth‚ nose‚ trachea‚ lungs‚ and diaphragm. Oxygen enters the
