Christina SentelleSC121-COLB- Unit 8: Assignment ( Bodies in Balance)I chose to explain the physiology the cardiovascular and the digestive system in the body in relation toenergy metabolism in the body, discuss the role of energy in the body and analyze how those two bodysystems interrelate to perform a named functions. For distinction analysis, energy as the ability to dowork together of the two body systems. Energy cannot be destroyed but it can be changed to anotherform. Without energy we would not be able to growth or move. To stay alive we need regular andpermanent supply of energy or else we would die. Without energy our body would not be able to carry outprocesses such as: * Growth and reconstructions of new cells and tissues as energy is necessary to supplybiochemical reaction that then is building larger organic molecules from simpler ones. * Active transportwithout energy wouldn’t be successful as energy is needed for moving the substances in and out of thecells e.g. by active transport amino acid is being delivered to the blood from the small intestine. *Movement as energy is necessary for all movements and human movements are occurring in certainstages: * Inside cells - chromosomes separating.* Whole cells – sperm swimming (to reach the egg sperm need to swim 7500 times its own length toreach the egg and without energy it would be impossible to do) * Tissues – muscles control* Whole organs – heart beating* Parts of whole organisms such as walking and talking.Also we need the energy from respiration to maintain our body at a constant 37C as we human are warmblooded which can advantage or disadvantage us. Being warm blooded can disadvantage as warm-blooded bodies are providing nice and warm environment for viruses, bacteria’s and parasites to live in.The advantage of being warm blooded is that we can move then it is cold, as if we were cold blooded wewouldn’t be able to move during the cold weather. As much as we need energy we also need food to keepus alive for humans food is like fuel and without it we would die. We need food to get energy to help usgrow and repair damaged cells and tissues. Also it is important to keep a balanced diet to preventbecoming underweight or overweight. When the body is taking more energy from food than is necessarythe oversupply will be stored under the skin as a fat and it will also start surrounding internal organs suchas heart. Also the location of a body fat is different in terms of sex hormones e.g. males tend to store thefat around their waist area, while women fat can be stored around buttocks or thighs. When body is notgetting enough energy from the food the body has to take out stored fat and protein. Then when suppliesare still low body is using the actual fabrics such as muscles they keep disappearing as the body has tokeep supplying different parts of the body to keep alive. Everybody has their own metabolism.
