The Mysterious Death of Randy Bilyeu
A millionaire named Forrest Fenn has hidden a treasure chest deep in the Rocky Mountains, in hopes to spark adventure and get people off the couch to seek fortune in the great outdoors. The treasure chest is known in the Rocky Mountains as the “Bronze Box,” which is filled with gold and precious gems. Fenn tells us the box is hidden somewhere between Santa Fe, New Mexico and the Canadian border at an elevation above 5,000 feet right in the middle of a rapidly changing climate. In this area where the treasure resides, temperatures can vary from day to evening; it’s not uncommon in summer months to drop below freezing, particularly at higher elevations which gives risk to frostbite or worse. Frostbite causes the body to divert blood flow from the surface as the temperature drops so the more important body parts stay warm the longest. This process utilizes several body systems and allows the body’s core to stay protected for as long as possible. Randy Bilyeu, a 54-year old retired mechanic who had moved from Florida to Colorado to seek out the treasure, was last seen on January 5th. His belongings were found near the Rio Grande river, south of Santa Fe, New Mexico. Severe frostbite has been concluded as his probable death. Investigators are still in debate regarding the true cause of his death.
Name that Body System - Question 1 (Highlight your answers in yellow.)
When blood flow is gone from the extremities for too long, the cells start to die. Depending on the severity of the damage, new cells will either replace the old or that part of the body that is lost to frostbite. Which system was MOST responsible for Randy’s frostbite?
A. Nervous
B. Circulatory
C. Musculoskeletal
D. Respiratory
Name that Body System - Question 2
Those that knew Randy stated he should not have gone treasure hunting because he had a pre-existing medical condition, known as asthma, from a long life of smoking. Asthma causes severe difficulties in breathing when under stress or mild exercise and can lead to death or serious injury without treatment. If Asthma was indeed the reason for Randy’s death instead of frostbite, which system would be MOST responsible?
A. Nervous
B. Circulatory
C. Musculoskeletal
D. Respiratory
Name that Body System - Question 3
Blood pressure typically rises during the winter due to constrictions in blood flow, which can lead to an increase in heart attacks, strokes, and other cardiovascular causes of death. Scientists at the Oregon University have uncovered a system that tells the body when to perform one of its most basic defenses against the cold: Shivering. The scientists have discovered the brain’s wiring system, which takes temperature information from the skin and tells the brain when the musculoskeletal system should start shivering. Which system was primarily responsible for initiating Randy’s shivering in the cold weather?
A. Nervous
B. Circulatory
C. Musculoskeletal
D. Respiratory
Name that Body System - Question 4
The ________system was triggered when Randy’s blood flow was limited in response to the severe cold temperatures. This led his brain to send impulses through the _________system to constrict blood vessels in the circulatory system and cause shivering. This is the body’s first line of defense in response to frostbite.
A. Nervous, Circulatory
B. Nervous, Musculoskeletal
C. Musculoskeletal, Nervous
D. Circulatory, Respiratory
What is homeostasis?
Show What You Know - Question 1 (Highlight your answers in yellow.)
You and your classmate are discussing different organs and organ systems within the human body. Your friend states that the excretory system includes multiple organs, and one of those organs is the lungs. You argue that the lungs can’t possibly be in the excretory system since it is part of the respiratory system. Which of the following choices would be the best statement that your friend would use to justify why the lungs help keep homeostasis via the excretory system?
a. The lungs bring in oxygen, which is a vital gas to keep our cells alive and healthy.
b. The lungs exhale carbon dioxide, which is a waste gas and needs to be removed from the body.
c. The lungs provide cells with a gas that is important for the cell process of respiration.
d. The lungs remove waste in the forms of solids, liquids, and gases that could be harmful for the body.
Show What You Know - Question 2
How do your respiratory and circulatory systems attempt to maintain homeostasis during exercise?
a. Your body produces more red blood cells to help provide energy to cells.
b. Your lungs produce more oxygen which is then delivered to the cells through the blood.
c. You experience an increase in blood flow which provides nutrients to cells to increase energy and remove wastes.
d. You experience an increase in breathing rate to obtain more oxygen which is delivered to cells through the bloodstream.
Show What You Know - Question 3
Food gives the body energy, which helps the body maintain homeostasis. In the morning, an athlete eats a nutritious breakfast to get energy to exercise. What are the main organ systems involved in the process of food from the athlete’s breakfast being broken down into nutrients and then delivered to the cells?
a. Digestive and excretory systems.
b. Digestive and circulatory systems.
c. Nervous and excretory systems.
d. Respiratory and circulatory systems.
Show What You Know - Question 4
The skin helps regulate body temperature by perspiration, which allows excess heat to leave the body. If you lost the ability to sweat, what could happen to you if you were running a marathon?
a. The body would overheat.
b. The body would react slowly.
c. The body would start to shiver.
d. The body would need more energy
Show What You Know - Question 5
In order to maintain homeostasis, the systems of the human body work together to keep a constant internal temperature. Which of the following best describes how the human body responds in a cold environment?
a. The digestive system produces more hormones to warm the body.
b. The nervous system signals the muscles of the muscular system to contract and warm the body.
c. The circulatory system delivers less carbon dioxide to the muscular system, resulting in stiffening of the muscles.
d. The skeletal system produces more blood cells that circulate through the blood vessels, increasing the warmth of the body
