Cellular Respiration Zoom in: muscle tissue cell mitochondria cellular respiration occurs in the mitochondria 3 body systems are needed to make the mitochondria work; digestion, circulation, and respiration Why digestion? through the digestive system the body acquires the food it needs to fuel all cells main food source needed are carbohydrates broken into glucose molecules the cell breaks the glucose into something smaller and sends it off to the mitochondria there the mitochondria uses these smaller pieces with oxygen to make energy for you Why circulation? the heart and vessels are responsible to pump and transport all nutrients to all parts of the body through tiny vessels called capillaries are things like glucose, oxygen and carbon
Overall, the respiratory system enables oxygen required by the mitochondria to enter the body, this is also the system that removes carbon dioxide which is a by product of respiration. (731 words) M1- Discuss the role of energy in the body. In this part of the essay I am going to be discussing the concepts of energy in the body. I will be explaining how energy comes from the diet and describing how it is transformed into energy used by the body and saying where it is used. “The first law of thermodynamics states that energy can neither be created nor destroyed”.
Diffusion helps to remove dissolved carbon dioxide from the blood and into the expelled air from lungs. Diffusion is the molecules (gas or liquid) moving from high concentration to low concentration. M1: Discuss the role of energy in the body. Our bodies need energy to work properly. The energy we need and use comes from the type of foods we eat.
The arteries carry nutrients and oxygenated blood to the body’s tissues. The veins return de-oxygenated blood to the heart, where the cycle repeats itself continuously. However the blood vessels have a closed type of cardiovascular system in which blood doesn’t come in direct contact with the body tissues. Instead the blood flows in restricted pathways called blood vessels. The blood vessels are pathways of blood flow in the body.
Identify three mechanical digestion activities. a. Chewing b. Mixing of food with saliva by tongue c. Churning food in the stomach and segmentation of the intestines 3. Name two feedback loops that regulate digestive system smooth muscle responsible for propulsive and mixing movements. Hormonal feedback loops and neural feedback loops. Neural Regulation of Mechanical Digestion 4.
Typing this paper, although optional, is encouraged. Your answers will be graded based on length, completeness of information and quality. This assignment will count as test grade. 1) Identify a food chain consisting of organisms in the movie. Include at least 4 organisms and be sure to identify which organisms are the producers, first level, secondary level, and tertiary level consumers.
Continue your writer report that you will submit with your graph. Consider the accuracy of the equipment used, normal variations in values when measuring and the reliability of the individual taking measurements. Evaluate the importance of homeostasis in maintaining a healthy functioning body (D2) The final part of the report allows you to bring together all your knowledge of homeostasis and review this information in order to form a final conclusion. In this assignment I will discuss the probable homeostatic responses to changes in the internal environment during exercise. When you are exercising different changes occur in the body to try and deal with the change in the environment and the reaction that occurs in the body.
Make sure that you use colour and make the poster clear, attractive and interesting. P2 Outline the structure of the main tissues of the body Produce a written assignment that shows an understanding of the main tissue types and the roles they play in two named organs. Two organs you could choose might be the stomach and the skin. Here are examples of tissues types that occur in these two organs: 1. The stomach has three layers of non-striated muscle in its wall and an inner lining of columnar epithelium with goblet cells.
Energy Systems D2 After I analyse each aspect of the energy systems I will then explain why they are so vital in helping us when participating in sporting activities. First lets start by looking at what ATP is. Adenosine Triphoshate, better known as ATP is the energy our body uses willingly to create movement such as contractions in the muscles. ATP consists of one adenine and three phosphate molecules. It is produced through the breakdown of foods that we eat.
1 Lipids GRT TASK 1 208.5.6 Rosina Lloyd Western Governor's University 2 A. Explain how energy is stored as fat, including identification of storage molecules and tissue. The molecule fat is store in the body in many forms. It can be stored in the body as a carbohydrate, which is used when the supply of fats is limited. Fat is also store in the system as triglycerides that forms three of our good saturated fatty acids.
