BIO 230 Human Biology Lecture Exam 3 Brother Wray Brigham Young University-Idaho
Questions and Answers Already Passed
Receptors - Answers Responds to a stimulus
Functions of respiratory system - Answers Protection
Voice Production
Gas Exchange
The respiratory system - Answers is completely lined with mucous membranes which acts as a
trap system
Sneezing reflex - Answers Can be triggered by even mild stimulation of the the nasal lining.
When stimulated, the receptors in the lining send impulses via the cranial nerve to sneezing
center in the medulla.
Rhinitis - Answers Inflammation of the mucous membrane of the nose, caused by a virus
infection (e.g., the common cold) or by an allergic reaction (e.g., hay fever).
Sinusitis - Answers inflammation of a nasal sinus.
Uvula - Answers During swallowing, the soft palate and the ______ move superiorly to close off
the nasopharynx, preventing food from entering the nasal cavity.
Coughing reflex - Answers Can help expel anything in the trachea
Are involved in voice production - Answers The larynx and vocal cords
Vibrate as air passes over them - Answers vocal cords
Laryngitis - Answers inflammation of the larynx, typically resulting in huskiness or loss of the
voice, harsh breathing, and a painful cough.
Pleural membranes - Answers line the lungs and thoracic cavity
Pleural cavity - Answers Is filled with lubricating pleural fluid
Pleurisy - Answers An inflammation of the pleural membranes and causes painful breathing
Collapsed lungs and pneumothorax - Answers Air in the pleural cavity
How oxygen is transported - Answers transported throughout the body via hemoglobin in the
red blood cells.
How is carbon dioxide transported - Answers transported from tissues to the lungs in a simple
dissolved form. In this process, metabolically-generated carbon dioxide gas simply diffuses into
, local capillaries, travels to the lungs via venous blood, and is exhaled .
Lung cancer - Answers caused by proliferation of abnormal cells
Botulism - Answers poisoning by bacterial toxin
Tuberculosis - Answers bacterial infection of the lungs
Mesothelioma - Answers partially deadly cancer caused by exposure to asbestos
Congestive heart failure - Answers impairs lung function
Colds and flu - Answers common viral respiratory tract infections
Emphysema - Answers Alveoli become permanently impaired
Bronchitis - Answers inflammation of the bronchi
Cystic Fibrosis - Answers An inherited condition in which a single defective gene causes the
mucous-producing cells in the lungs to produce a thick, sticky mucous.
Asthma - Answers spasmodic contraction of the bronchi
Functions of the nervous system - Answers Receives Sensory Input
Integration - processing input and generating a response
Homeostasis
Mental Activity
Control of Muscles and Glands
Neurons - Answers The communication cells of the nervous system
Different types of neurons - Answers Sensory neuron, interneuron, motor neuron,
Function of Myelin Sheaths - Answers Protect the neuron, provide insulation, and increase the
speed of impulse transmission
Multiple sclerosis - Answers A demyelinating disease in which the insulating covers of nerve
cells in the brain and spinal cord are damaged. This disrupts the ability of parts of the nervous
system to communicate, resulting in physical, mental, and sometimes psychiatric problems.
Action potentials - Answers Electrical signals that allow communication between cells
The electrical impulse is passed along the axon.
What happens when the impulse hits the end of the axon? - Answers A neurotransmitter is
