System Anatomy & Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac muscle) is a specialised

contraction in skeletal muscle is caused by specialized intracellular thin and thick filaments‚ actin and myosin‚ sliding past each other. Contraction and relaxation of skeletal muscle bring about body movements. These body movements are voluntary and facilitated by the somatic nervous system. Near contact between somatic motor neurons and the muscle fibers are referred to as neuromuscular junctions. It is at the neuromuscular junctions that neurons are able to transmit a signal to the muscle fibers causing

exercise. Although stretching doesn’t reduce bodily fat nor does it gain muscle; it does set a good foundation for you to perform the necessary activities that lead to good health. With proper flexibility‚ many functions that were previously not achievable can now be done. For instance‚ a tennis game can be fun for a little while. But as your muscle tense up‚ you risk probable sourness and cramping. With good flexibility‚ your muscles stay loose and relaxed and your attitude toward the tennis game and

ANATOMY AND PHYSIOLOGY OF THE RESPIRATORY SYSTEM The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. Respiration is achieved through the mouth‚ nose‚ trachea‚ lungs‚ and diaphragm. Oxygen enters the
