Reflexes play an important role in human physiology and the ways in which the body adapts to different stimuli. Reflexes have been adapted over time to ensure survivability and fitness. In this video, we cover two reflexes that can be commonly associated to college students in the United States. The baroreflex has been adapted physiologically to compensate for the sudden change in blood pressure throughout the body. This response occurs in order for the human body to meet critical metabolic demands and prevents the possible health risks that could occur without this reflex. When the body senses an extreme drop in blood pressure, receptors located in the neck and aorta send signals to increase heart rate and dilate the blood vessels. This increases the blood flow and insures that enough oxygen is carried to various body tissues. In the video, a student experiences a failure in the baroreflex #39;s ability to compensate for the sudden change in blood pressure taking place when the student stands. The fight or flight response is an important process involved in rapidly adjusting to dangerous situations. When the body senses danger, the adrenal gland secretes hormones that can be delivered to the blood and initiate a life-saving response. Some of the ways in which the body responds to these hormones involves the dilation of the pupils, a rise in heart rate, and constriction of blood vessels. As a result, changes taking place in the body are regulated in order to avoid danger. The ...From:DreyerJakeViews:41 6ratingsTime:03:43More inPeople Blogs
