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

in more air and therefore oxygen‚ which is supplied to the muscles. These activities make the heart more efficient. Aerobic exercise uses oxygen to keep large muscle groups moving continuously at an intensity that can be maintained for at least 20 minutes. Aerobic exercise uses several major muscle groups throughout the body‚ resulting in greater demands on the cardiovascular and respiratory systems to supply oxygen to the working muscles. Stretching exercises consists of neck roll‚ should roll‚

The musculoskeletal system includes bones‚ joints‚ skeletal muscles‚ tendons‚ and ligaments. The response this exercise does to the body is increased blood supply for muscles to work for longer and harder when exercising‚ muscle pliability will also develop as regular muscles are being used and developed making them stronger overall. Increased respiratory rate‚ increased fuel metabolism‚ increased oxygen consumption and also increased muscle temperature these are some of the features that will

and moving The human body is only able to assume it’s different posture and maintain its structure due to the skeletal system. The skeletal system is made up of bones which have an outer hard cortical layer and an inner soft trabecular layer made of cancellous bone. Within some long bone is the all important marrow from where all the blood cells originate after maturation. The skeletal system can be divided into 2 groups: 1. Axial skeleton: The bones here include the skull and bones of the vertebrae

electromyogram (EMG) is a test that is used to record the electrical activity of muscles. When muscles are active‚ they produce an electrical current. This current is usually proportional to the level of the muscle activity. An EMG is also referred to as a myogram. EMGs can be used to detect abnormal electrical activity of muscle that can occur in many diseases and conditions‚ including muscular dystrophy‚ inflammation of muscles‚ pinched nerves‚ peripheral nerve damage (damage to nerves in the arms and

Duchenne muscular dystrophy (DMD) is one disease of the muscles that predominantly affects males and is generally diagnosed between the ages of two and five years (Duchenne Foundation Australia‚ 2015). According to Muscular Dystrophy Australia (2015)‚ there are approximately “…one in 3500 live male births throughout the world” (para. 1). DMD may be inherited by individuals with the defective gene‚ however‚ one-third of DMD cases occur as a spontaneous mutation arising in the affected individual (MDA

Exercising has the capability to increase the body’s organ systems. The body’s main physiological systems are the cardiovascular‚ respiratory‚ skeletal‚ digestive‚ endocrine‚ immune and nervous system. The skeletal System acts as a support and attachment sites for muscles and protects
Premium Muscle Heart Metabolism
Skeletal muscle fibres can change from high activity‚ in which a high amount of ATP is used to a low level of activity‚ with only a small amount being used. The ATP in the muscle fibres is enough to allow muscle contractions for a few seconds. When muscle contraction continues more ATP is needed. Aerobic glycolysis Oxidation of glucose requires a different enzyme and a coenzyme for each step. Coenzyme A is used at this stage in cellular respiration‚ which is derived from from a B vitamin called
