Lab 9 Report: Exercise Physiology Introduction When the human body is put to work and undergoes any sort of activity‚ it requires more energy and resources in order to sustain this. The cells in muscles and organs must work faster‚ and thus require more energy to do so. The body compensates by increasing heart rate and respiration in order to increase the amount of oxygen entering‚ carbon dioxide leaving‚ and rate at which these gases are delivered to cells throughout the body. In this lab‚ we

Digestion exercise T 8 he digestive system is a physiological marvel‚ composed of finely orchestrated chemical and physical activities. The food we ingest must be broken down to its molecular form for us to get the nutrients we need‚ and digestion involves a complex sequence of mechanical and chemical processes designed to achieve this goal as efficiently as possible. As food passes through the gastrointestinal tract‚ it is progressively broken down by the mechanical action of smooth muscle and

REVIEW SHEET EXERCISE 2 Skeletal Muscle Physiology NAME: Jasmine Young LAB TIME/DATE: 1. Define each of the following terms: • motor unit - A motor unit consists of a motor neuron and all of the muscle fibers it innervates. • twitch - Skeletal Muscle twitch is the mechanical response to a single action potential. It has three phases known as the latent‚ contraction‚ and relaxation phase. • threshold - the threshold is the minimal stimulus needed to cause a depolarization of the muscle plasma membrane

Laboratory – Muscle Physiology A. MUSCLE TONUS Observations‚ Report and Conclusion: A. Define muscle tonus and give its importance * Muscle tonus refers to a state of slight muscular contraction maintained by synchronous impulses of low frequency‚ discharged by the spinal motor neurons. * Reflex in nature. * Muscle tonus is a small amount of tension in the muscle due to weak‚ involuntary contractions of its motor units. Muscle tonus is important in a sense that it governs the

There are many aspects of being an exercise physiology major. The field of exercise physiology has always interested me‚ but I was never sure about what career path I would choose. This year has really given me a better understanding of what path I would like to pursue. I really wanted to be an occupational therapist‚ but shortly after decided that I wanted to be a physical therapist. According to Writing‚ the annual salary for a physical therapist is in a range from $70‚000-$100‚000 (2010). I wanted
