in the tendons‚ which bind muscle to bone‚ and ligaments‚ which join bones together. Blood connective tissue is used in transporting substances from one part of the body to another. Adipose tissue stores large droplets of fat that swells when stored and shrinks when used for energy. Bone is rigid connective tissue which provides support for muscle attachment and protects internal organs. 3. Smooth muscle tissue is found surrounding hollow tubes and wave like contractions move food particles through

believer that if you enjoy the same thing that motivates you; then your goal will have a greater chance of success. Isotonic exercise could also be beneficial to the appearance of my body. This requires weight lifting and muscle building. Although I am not too concerned about muscle growth I would like to see certain areas begin to firm up and take shape. I am looking for a tone and more lean body. Running and jogging would be my two key elements in

The Muscular System: Muscle Metabolism 1. List the three roles of ATP in muscle contraction: 1. ________________________________ 2. ________________________________ 3. _________________________________ 2. The potential energy in ATP is released when the terminal high-energy bond is broken by a process called ___________________________. Write the end products of this process: ATP (+ H2O) → _________________ 3. Rebuilding ADP into ATP with a new source of energy is carried out by a process called

Tissues Tissues are sets of the same cells carrying out particular functions these include; epithelial‚ connective‚ muscle and nervous. Epithelial tissues are the inside layer of internal and external surfaces and body cavities‚ including ducts carrying secretions from glands. They may be composed of some layers of cells‚ called compound epithelia or just a single layer which is known as simple epithelia. The lowest or bottom layer of cells is attached to the basement membrane for support and

classified as increasing strength and endurance of a muscle. Muscular Strength and Endurance testing was performed to provide you with experience in administering muscular fitness tests designed to assess muscular strength and muscular endurance using constant-resistance exercises and exercise machines. Muscular strength is defined as the maximum amount of force a muscle can produce in a single effort. It is generally measured by a single maximal contraction‚ for example weight-lifting. Muscular endurance

ATP/PC (without oxygen) LACTIC ACID (without oxygen) AEROBIC What is it? The alactacid system (ATP/PC) uses the stored ATP modules in the muscles‚ for a few seconds or one explosive moment. The ATP molecule is then unable to provide energy to the working muscles. To continue the muscular movement ‚ the body relies on creatine phosphate (PC) in a secondary reaction. This system is used for short bouts of exercise. Especially those lasting up to 12 seconds. the lactic acid system will continue

Chapter 1 ELO’s Describe the basic functions of living organisms. A. Responsiveness – organisms respond to changes in their immediate environment (long term changes is adaptability) B. Growth – over a lifetime‚ organisms grow larger through an increase in size or number of cells. Differentiation is when cells have specialized functions C. Reproduction – Organisms reproduce‚ creating subsequent generations of similar organisms D. Movement – Organisms are capable of movement

to provide respiring muscle tissues with the right amount of oxygen. For example‚ when the body is exercising‚ more oxygen is needed in the muscles‚ so the heart needs to pump faster to accommodate this. The sympathetic nervous system is responsible for the increase of the heart rate during physical exercise‚ fear or stress. The parasympathetic nervous system slows down the heart rate during periods of rest. The Sino-atrial node sends electrical impulses around the heart muscle and tells it how fast

abuse. In their experiment‚ Anttila et al. (2008) tested if testosterone can regulate the aerobic capacity of skeletal muscles by injecting mice with certain amounts of testosterone and then studying the levels of myoglobin‚ a protein that plays a role in supplying oxygen to mitochondria during exercise. They demonstrated that the myoglobin concentration in skeletal muscles is directly related to testosterone. Therefore‚ an increase in testosterone will allow for more muscular potential. In addition

during physical activity. Sodium‚ for example‚ plays a major role in muscle contraction and conduction of nerve impulses. Muscle contraction is directly related to the amount of the force a muscle can exert. Therefore‚ if there is a sodium deficit‚ the muscle will not be able to contract as well‚ decreasing the intensity at which you workout or perform. Exercise intensity is crucial in achieving muscular hypertrophy (gain in muscle mass). A sodium deficit in the body can also produce several negative
