Cardio
This chamber receives oxygenated blood from the body
Right atrium
This leaf-shaped cartilage protects the airway during swallowing by snapping shut over the glottic opening.
What is the epiglottis?
This branch of the autonomic nervous system triggers the "fight-or-flight" response, increasing heart rate and dilating bronchioles.
What is the sympathetic nervous system?
This type of cellular metabolism occurs in the presence of o2
What is aerobic metabolism?
This is the long, heavy bone of the upper leg, known as the largest bone in the body.
What is the femur?
This directional term describes the front surface of the body.
What is anterior (or ventral)?
This large vessel takes deoxygenated blood away from the right ventricle and routes it to the lungs.
What is the pulmonary artery?
These microscopic, grape-like sacs are the functional site of gas exchange in the lungs.
What are alveoli?
This is the basic, functional nerve cell that transmits electrical signals throughout the body.
What is a neuron?
When cells are deprived of oxygen, they switch to anaerobic metabolism, which produces this toxic byproduct.
What is lactic acid (or lactate)?
This tough, fibrous band of tissue connects one bone to another bone to stabilize a joint.
What is a ligament?
This directional term means farther away from the midline of the body.
What is lateral?
This is the clinical term for the amount of blood ejected by the left ventricle in a single contraction
What is stroke volume?
This term describes the volume of air inspired or expired during a single normal, quiet respiratory cycle.
What is tidal volume?
This large part of the brain controls conscious thought, memory, and voluntary movement.
What is the cerebrum?
This organ releases insulin and glucagon to maintain homeostatic blood glucose levels.
What is the pancreas?
This part of the skeleton includes the skull, spine, and ribcage, forming the central axis of the body.
What is the axial skeleton?
In EMS, an injury that is closer to the trunk or point of attachment is described using this term.
What is proximal?
This mathematical product of heart rate and stroke volume dictates total blood flow per minute.
What is cardiac output?
In healthy patients, the primary chemical drive to breathe is triggered by an elevation of this gas in the blood.
What is carbon dioxide (CO₂)?
This major division of the nervous system consists of only the brain and the spinal cord.
Central Nervous System
This is the term for the sum of all chemical reactions that happen inside the body to sustain life.
What is metabolism ?
These are the three distinct regions of the spine that hold moveable vertebrae, moving from top to bottom.
What are cervical, thoracic, and lumbar?
When a patient is lying flat on their back facing upward, they are in this specific body position.
What is supine?
This is the largest chamber of the heart
left ventricle
This physiological mechanism, crucial to monitor during respiratory failure, is the physical movement of air into and out of the lungs.
What is ventilation?
This structure at the base of the brain connects to the spinal cord and controls basic survival functions like breathing.
What is the brainstem?
This simple sugar is the primary source of fuel and energy for the body's cells.
What is glucose?
This flexible, smooth connective tissue pads the ends of bones at joints to reduce friction and absorb shock.
What is cartilage?
This imaginary vertical line runs down the side of the body, starting directly in the middle of the armpit.
What is the mid-axillary line?
