Identify the organs of the male reproductive system and discuss the function of each. correct answers -Testes: produces sperm and testosterone -Epididymis: temporarily stores sperm from testes -Scrotum: keeps sperm below body temp -Vas deferens: transports sperm to ejaculatory duct -Seminal vesicle: creates seminal fluid -Prostate: creates prostatic fluid -Bulbourethral gland: cleanses urethra of urine prior to ejaculation -Urethra: releases semen Describe the regulation of kidney function (nervous, hormonal, and kidney self-regulation). correct answers Explain the functions of the respiratory system correct answers The respiratory system is what allows us to breathe and exchange carbon dioxide for oxygen. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. Name the structures of the respiratory system from the nose to the alveoli of the lungs, and describe the function of each. correct answers Differentiate between the conducting and respiratory zones of the respiratory system correct answers The conducting zone is most of the respiratory tract that conducts gases into and out of the lungs, but excludes the respiratory zone that exchanges gases. The respiratory zone includes the respiratory bronchioles, alveolar ducts and alveoli, and is the site of oxygen and carbon dioxide exchange with the blood. Describe the structure and function of the lungs and the pleural coverings. correct answers Lungs are paired organs primarily made of elastic tissue; their function is to take in oxygen and transport it to the blood; Pleura is a visceral serosa that decreases friction during breathing. Describe the structure of the respiratory membrane. correct answers an air-blood barrier in alveoli formed by alveolar and capillary walls
