Exercise 2 - Organ Systems Overview-1 (1)

Exercise 2 – Organ Systems Overview Name _Islande Similien____________ Instructions and Review Sheet Once you have completed the below activities, please answer the questions on the following pages and submit this completed document to me in Canvas. You must have a copy of the lab manual to complete this exercise. Please read the entire exercise in your lab manual. Pay particular attention to the figures – the practical portion of the exam will use images and figures taken from the lab manual and handouts like this one. Activities 1-4: In class we do a quick dissection of a rat to become familiarized with the basic mammalian organ systems – although they are shaped a bit differently in a human and a rat, they are broadly similar. I regret that you cannot do the dissection (you may not!) but you can learn the basic anatomy by carefully reading your lab manual and studying the figures. Please also watch this short video demonstration of a rat dissection: https://www.youtube.com/watch?v=g2RSX2QNp64 Activity 5: Study the figure and identify the location of the listed structures. Assign all the structures listed above to one of the following organ system categories. Digestive: stomach, small intestine, large intestine, liver, gallbladder, rectum, mesentery Urinary: kidney, ureter, bladder Cardiovascular: heart, descending aorta, inferior vena cava Endocrine: thyroid gland, adrenal gland, pancreas Reproductive: uterus Respiratory: lungs, bronchi, trachea Lymphatic: spleen Nervous: brain, spinal cord Organ System Overview 1. Use the key below to indicate the body systems that perform the following functions for the body; note that some responses are used more than once. Key: a. cardiovascular d. integumentary g. nervous j. skeletal b. digestive e. lymphatic/immunity h. reproductive k. urinary c. endocrine f. muscular i. respiratory _k___ 1. rids the body of nitrogen-containing wastes _c__ 2. is affected by removal of the thyroid gland
