Unit 2: The Psychology of Fitness Assignment 1: The Body’s Response to Acute Exercise Introduction: As a health and fitness instructor I need to be able to apply my anatomical and physiological knowledge to practical activities and exercises. I have conducted practical assessments to explore how the body responds to physical activity and exercise. I have then written a report‚ including all the anatomical and physiological changes that occur within each of the bodily systems. Acute exercises

sympathetic division and the parasympathetic division. The main process of the sympathetic division is to stimulate the fight-or-flight response in the body‚ which means it is in charge of stimulates actions. In the sympathetic system‚ epinephrine and norepinephrine are the main neurotransmitter. In the sympathetic system‚ there are two neurons involved in transmission and they are the pre-ganglion and post-ganglion. The preganglionic fibers are short and they originate in the brain stem and sacral

1. What is metabolic absorption? “All the cells take in and use nutrients and other substances from their surroundings. Cells of the intestine and the kidney are specialized to carry out absorption. Cells of the kidney tubules reabsorb fluids and synthesize proteins. Intestinal epithelial cells reabsorb fluids and synthesize protein enzymes” (McCance & Huether‚ pg. 2). 2. What uses oxygen to remove hydrogen atoms in an oxidative reaction? “Peroxisomes are so named because they usually contain

The Endocrine System FOCUS: The endocrine system is one of the major regulatory systems in the body‚ along with the nervous system. However‚ the endocrine system responds more slowly‚ and has a longer-lasting‚ more general effect on the body than the nervous system. Endocrine tissues internally produce hormones which are released into the blood‚ where they are carried to target tissue and produce a response. Some hormones bind to receptors on the surface of the cell membrane‚ producing permeability

The neurotransmitters are involved in sympathetic nervous system are: acetylcholine (sympathetic ganglion) and norepinephrine (post-ganglionic) and for the parasympathetic nervous system are: acetylcholine (preganglionic) and norepinephrine (noradrenaline) or epinephrine

it dilates the pupil‚ accelerates the heartbeat then inhibits the digestion to the stomach‚ pancreas‚ and liver‚ in the pancreas the stimulation of glucose for the liver takes place; subsequently‚ moving on down to the secretion of the epinephrine‚ and norepinephrine; which in turn relaxes the bladder and stimulates ejection for the male. On the other hand‚ the parasympathetic nervous system is the calming part of the body‚ and it is as follows; the pupil contracts and slows down the heartbeat‚ and
