This bone is the lower jaw.
What is the mandible?
100
These tiny sacs in the lungs are the primary location of pulmonary gas exchange.
What are the alveoli?
100
This chamber pumps oxygen-rich blood into the aorta.
What is the left ventricle?
100
Inadequate tissue perfusion is commonly called this.
What is shock?
100
The brain and spinal cord together make up this division of the nervous system.
What is the central nervous system?
200
This lower-leg bone is larger and located medially.
What is the tibia?
200
This term means the movement of air into and out of the lungs.
What is ventilation?
200
These vessels carry blood away from the heart, regardless of oxygen content.
What are arteries?
200
Perfusion requires an effective pump, functioning vessels, adequate blood, and these ultimate recipients of oxygen and nutrients.
What are the cells/tissues?
200
This division of the autonomic nervous system produces the classic "fight-or-flight" response.
What is the sympathetic nervous system?
300
This structure connects muscle to bone, unlike a ligament, which connects bone to bone.
What is a tendon?
300
During inhalation, this primary respiratory muscle contracts and moves downward.
What is the diaphragm?
300
This blood component is primarily responsible for carrying oxygen.
What are red blood cells?
300
A patient's blood pressure appears normal, but the patient is pale, confused, and has a weak radial pulse. This demonstrates why blood pressure alone does not equal this.
What is perfusion?
300
This abdominal organ produces bile, stores glucose, and performs important metabolic and detoxification functions.
What is the liver?
400
The femoral head fits into this socket of the pelvis to form the hip joint.
What is the acetabulum?
400
During inhalation, thoracic volume increases while pressure inside the thorax does this.
What is decreases?
400
Oxygen-poor blood travels from the right ventricle toward the lungs through these vessels.
What are the pulmonary arteries?
400
When cells do not receive enough oxygen, they shift from aerobic metabolism toward this less-efficient form of metabolism.
What is anaerobic metabolism?
400
Urine travels from each kidney to the bladder through this structure.
What is the ureter?
500
An EMT documents an injury to the lateral side of the lower leg. This bone is located beneath that area and is smaller than its neighboring bone.
What is the fibula?
500
A patient has chest rise and air is entering the lungs, but oxygen is not effectively moving from the alveoli into the bloodstream. Ventilation is occurring, but this process is failing.
What is oxygenation?
500
Place these in the correct order after blood enters the right atrium: right ventricle, pulmonary artery, tricuspid valve, pulmonary valve.
What is tricuspid valve → right ventricle → pulmonary valve → pulmonary artery?
500
A patient rapidly loses a large amount of blood. Explain the sequence: decreased circulating volume → decreased tissue blood flow → decreased cellular oxygen → increased ______ metabolism.
What is anaerobic metabolism?
500
A trauma patient becomes tachycardic, tachypneic, pale and cool, and increasingly anxious after significant blood loss. These findings primarily represent the body's attempt to preserve this physiologic process.
What is perfusion / oxygen delivery to vital organs?
