05 Feb The pleura of the lungs

PHA1500 A Structure and Function of the Human Body Module 05 Quiz The Respiratory and Urinary Systems Question 1 Gas exchange in the lungs occurs in the: Answers: Alveolar ducts Alveoli Bronchi Trachea Question 2 For air to enter into the lungs, the intrapulmonary pressure (pressure within the lungs) has to be higher than the atmospheric pressure. Answers: True False Question 3 What portion of the nephron is charged with making urine? Answers: Afferent arteriole Bowman’s capsule Renal corpuscle Renal tubule Question 4 Renal insufficiency occurs when there is extensive damage to nephrons, impairing the ability of the kidney to function. Answers: True False Question 5 Which hormone causes an increase in blood volume and pressure? Answers: Atrial natriuretic peptide Antidiuretic hormone Growth hormone Parathyroid hormone Question 6 What is the role of the epiglottis? Answers: Prevents food and liquids from entering into the larynx and trachea Helps filter the incoming air Prevents the collapse of the lungs Provides moisture to the incoming air Question 7 The respiratory muscles allow for the thoracic cavity to expand, which increases the lung volume and decreases the intrapulmonary pressure. Answers: True False Question 8 What is the main muscle involved in pulmonary ventilation? Answers: Rectus abdominis External intercostals Diaphragm Internal intercostals Question 9 What muscle is not involved in the pulmonary ventilation (respiration) process? Answers: Diaphragm muscle Sternocleidomastoid (SCM) muscle Intercostal muscles Latissimus dorsi muscle Question 10 For oxygen gas exchange to occur between the lungs and circulatory system (blood vessels) there has to be a high concentration of oxygen in the blood vessels and a low concentration of oxygen in the lungs. Answers: True False Question 11 What statement is true regarding the upper respiratory system? Answers: It consists of the nasal cavity, pharynx, larynx, and trachea. The pharynx contains the vocal cords. The epiglottis assists filtering the incoming air. The nasal cavity will assist in filtering, warming, and humidifying the incoming air. Question 12 The urethra transports urine from the kidney to the bladder. Answers: True False Question 13 Reabsorption of nutrients and substances within the kidneys occurs within the renal tubular portion of the nephron. Answers: True False Question 14 What is the basic functional tissue of the urinary system? Answers: Bladder Ureter Nephron Kidney Question 15 The pleura of the lungs assist in the pulmonary ventilation and allow the lungs to expand without any friction in the thoracic cavity. Answers: True False Question 16 Which respiratory condition is marked by spasms in the bronchi making it difficult to breathe? Answers: Asthma Chronic obstructive pulmonary disorder Cystic fibrosis Pulmonary fibrosis Question 17 What statement is true regarding the kidneys? Answers: Both kidneys share one ureter that drains to the bladder. Internally, it is only composed of the medulla region. Damage to the nephrons will cause kidney dysfunction and impairment to their overall function. The erythrocytes are commonly filtered into the Bowman’s capsule region. Question 18 The term micturition refers to the process of sending urine down from the kidneys to the bladder. Answers: True False Question 19 Which portion of the nephron is involved in producing the filtrate from the blood? Answers: Renal corpuscle Collecting duct Renal tubule Ureter Question 20 The glomerulus is the portion of the nephron that fluid, mostly blood plasma, is filtered out of and is collected in the Bowman’s capsule. Answers: True False
