The muscular system is one of the most complex organ systems in the body‚ and it is imperative to the body’s survival‚ as it serves many significant functions‚ including movement‚ protection‚ posture‚ and heat production just to name a few. The muscular system has three types of muscle: skeletal‚ smooth‚ and cardiac. However‚ the main focus will be on the skeletal muscles and how they contract‚ as well as fatigue and respond to changes in temperature. In terms of the anatomy of the skeletal muscle

“Physiological regulation of fluid compartment volumes and chemical composition is critical for normal cell function.” It is important that the human body has the ability to maintain a constant internal environment referred to as homeostasis (Waugh and Grant 2010). Claude Bernard was a 19th century French physiologist who first discovered the concept of homeostasis. But it was Walter Cannon‚ a 20th century American physiologist who devised the word “homeostasis” (Marieb and Hoehn 2007). Temperature

molecules are broken down into simpler units by the addition of water. Polysaccharides : They are insoluble in water‚ tasteless‚ do not crystallize and a non-reducing agent. Common polysaccharides are starch‚ glycogen and cellulose. Starch is found in wheat‚ rice‚ potatoes. Glycogen is excess starch that is stored in the liver and mucle cells. Cellulose makes up cell wall of a plant cell. Lipid : Contain Carbon‚ Hydrogen and Oxygen 2 common lipids are Triglyceride and Lipoids Triglyceride

and muscles. Glucose comes from two major sources: food and your liver. Sugar is absorbed into the bloodstream‚ where it enters cells with the help of insulin. Your liver stores glucose as glycogen. When your glucose levels are low‚ such as when you haven’t eaten in a while‚ the liver converts stored glycogen into glucose to keep your glucose level within a normal range. With Type 1 Diabetes there is no insulin to let glucose in the cells‚ so sugar builds up in your bloodstream‚ where it can cause
