Tennis is a sport that has many unique benefits. It is a very physical activity that really works the cardiac muscle. The circulatory system which is propelled by the cardiac muscle will transport nutrients‚ including oxygen‚ to the working muscles and remove the waste products including carbon dioxide and water away from the working muscles. Tennis places a high demand on the cardiovascular system‚ more so in singles than in doubles. The running in tennis improves endurance. The quick spirts of

the muscle increases in size and bulk. Hypertrophy is a result of an increase in the volume of contractile proteins within the muscle cell so they can contract with greater force. The number of muscle fibres stays the same. In general males have a greater potential for increases in muscle bulk due to higher levels of testosterone. Increases in tendon strength - tendons are tough bands of fibrous connective tissue designed to withstand tension forces along their length. Like muscles‚ tendons

neurotransmitter that has an inhibitory effect on vertebrate cardiac muscle. The neurotransmitter does this by releasing neurons which activates a signal transduction pathway. As a result‚ the G protein in the pathway stops adenylyl cyclase and opens the muscle cell membrane’ potassium channels. These two actions result in a reduction in the cardiac muscle contraction. Another chemical known as epinephrine has the opposite effect on cardiac muscle. In the wall of the right atrium‚ there is a cluster of

skeletal muscle instead. When we are exercising there is more blood in our arterial circulation. Where did this blood come from and how did it get there ? When the cells within the body are more metabolically active‚ they use more fuel‚ such as glucose and oxygen. Therefore during exercise‚ specifically in parts like the skeletal muscles‚ the blood flow through the tissues is dramatically increased during contraction‚ resulting in blood flow up to 15 to 20 times greater then resting muscles.

Anatomy and Physiology Introduction In this assignment i will carry full investigation and analysis on the Skeletal system‚using my class notes‚researching on the internet and reading books. The Skeletal system is the system of bones‚ associated cartilages and joints of human body. Together these structures form the human skeleton. Skeleton can be defined as the hard framework of human body around which the entire body is built. Almost all the hard parts of human body are components of human

i) The body needs an increased cardiac output during exercise because the increased consumption of oxygen and nutrients by muscle cells requires more blood supply. The functions of blood include delivering oxygen‚ removing CO2‚ removing heat and delivering nutrients and water. Therefore‚ blood flow is important in cellular respiration‚ which is the process where ATP is produced through the conversion of metabolites‚ also involving the consumption of oxygen and release of CO2 as a waste product.

The muscular system consists of about 650 muscles and is responsible for the movement of the human body. The body is made up of three types of muscle tissue: skeletal‚ smooth and cardiac. Each of these has the ability to contract and expand‚ which allows the body to move and function. Muscle tissue is also found inside of the heart‚ digestive organs‚ and blood vessels‚ where the muscles serve to move substances throughout the body. The heart‚ cardiac muscle‚ is like a pump that sends blood around

is responsible for ensuring the body has a constant supply of oxygen‚ whilst removing carbon dioxide. It is made up of six organs and there are three major parts of the system; the airway‚ the lungs and the muscles of respiration. The respiratory system supplies the oxygen needed for the cardiac work load and its main function is gaseous exchange (Taylor‚ T cited in Inner Body).
