The atria receive blood returning to the heart from the body and the ventricles pump blood from the heart to the body. Valves allow blood to flow in one direction between the chambers of the heart. The Heart Wall The heart is composed of cardiac muscle which enable the heart to contract and allow the synchronization of the heart beat. The heart wall is divided into three layers: the epicardium‚ myocardium‚ and endocardium. * Epicardium - outer protective layer of the heart. * Myocardium

Slow-Oxidative (Type I) Muscle Fibres Shelby Daye Skeletal muscles are classified as striated and voluntary. They are found in muscles that maintain low-intensity contractions for long periods without fatigue. A single skeletal muscle cell is referred to as a muscle fibre. There are three types of muscle fibres found in the human skeletal muscle system including slow-oxidative fibres‚ fast-oxidative fibres and fast-glycolytic fibres. These three fibres are each defined by their biochemical capacities1

Increasing population contributes to land and space diminishing‚ resulting in high demand for what is available. Industry and markets are in the city‚ attracting buyers who want to have the convenience of living near commercial properties.

“nature of teaching” hypothesis states how difficult it is to evaluate a teacher. This hypothesis shows that the likelihood of merit pay working in public school very inconceivable‚ do to all the other factors that affect public school curriculum‚ like focusing on a topic for longer then the curriculum states should spent on a topic. On the contrary the ”political cost” hypothesis insists that there is nothing ingrained in teaching that makes merit pay not work. The hypothesis uses the statistics

HOW TO GAIN MUSCLES. Introduction. The assignment topic touches on a very important part of the human body a muscle. This is a soft tissue found on most animals and is made of cells that contain protein filaments of actin and myosin that slide past one another‚ producing a contraction that changes both the length and the shape of the cell. It function to produce force there location on the body or according to the functions and roles they play. They are the cardiac muscles (muscles covering the
