- Some athletes have drink beet juice (yes, juice from beets) to improve their endurance performance. Beet juice is known to contain high levels of a molecule called nitric oxide (NO) which may improve blood flow from lungs to working muscles by causing the dilation (widening) of blood vessels. Select the pair below that includes the most related subdiscipline and physiological system. O lungs / muscles O motor behavior / endocrine O sports nutrition / cardiovascular O biomechanics / cardiovascular O kinesiology/thermoregulationShow and explain how an organism maintains homeostasis through the interaction of various organ systems in the body.Homeostasis involves maintaining Select one: a. body conditions outside the normal range b. a relatively constant internal environment in the body c. the external environment to accommodate the body's needs d. the body in a fixed, unchanging state
- When you exercise, your body depletes oxygen faster. As a result, respiration and depth of breathing increases to take in more oxygen. In addition, your heart rate increases to speed up the delivery of oxygen to your muscles that are exercising. What type of homeostatic mechanism does this represent? a) Positive feedbackb) Negative feedbackc) FeedforwardRiding a bicycle requires additional energy from leg muscles. Which of the following conditions may result from this activity, and which response helps restore the body to its normal condition? * decreased oxygen can be replaced by digesting an apple. increased carbon dioxide in the blood can be removed by breathing faster. increased sugars in the bloodstream can be diluted by drinking water. increased salt wastes can be removed by the heart. No answeridentify the four components of negative feedback loop and explain what would happen if secretion of a body chemical controlled by a negative feedback system became to great
- Compare the body systems in a plant and an animal when relating to a) transporting materials around an organism b) nutrition. Make sure to list which tissues, organs and body systems are involved for each processDescribe how negative feedback and positive feedback are involved in homeostatic regulation.Define anatomy and explain the importance of understanding the relationship between structure and function. Define physiology and state two major goals of physiology. Describe six levels of organization of the body, and give the major characteristics of each level. List 11 organ systems and give the major functions of each. List six characteristics of life. Define homeostasis and explain why it is important. Diagram a negative-feedback mechanism and a positive-feedback mechanism, and describe their relationships to homeostasis. Describe a person in the anatomic position. Define the directional terms for the human body, and use them to locate specific body structure. Define the parts and regions of the body. Name and describe the three major planes of the body and an organ. Describe the major trunk cavities. Describe the serous membrane, and give their functions.
- Describe the organ systems of the human body and their major componentsThe respiratory system is capable of absorbing oxygen and excreting carbon dioxide. The digestive system absorbs nutrients from the diet and excrete indigestible material including wastes. Likewise, the urinary system is capable of absorbing and excreting water and electrolytes according to the needs of the body. These functions may appear to be distinct and separate from each other, but the systems are so organized that they are interdependent on each other and together contribute to the welfare of the body by keeping it in balance or in a state of homeostasis. Create a concept map that illustrates the physiology of acid base balance that unites the three systems (Respiratory, Digestive and Urinary systems) together.In______, physical and chemical aspects of the body are being kept within tolerable ranges by body are being kept within tolerable ranges by controlling mechanisms. a. Positive feedback b. Negative feedback c. Homeostasis d. metastasis
