This chamber receives oxygen-poor blood from the body.
Right atrium
Tiny air sacs where gas exchange occurs.
Alveoli
QUADRUPLE JEOPARDY: Single-celled prokaryotic organisms.
What are bacteria?
The body's first physical barrier against pathogens.
Skin
Clear outer structure that helps focus light.
Cornea
DOUBLE JEOPARDY: This vessel carries oxygen-poor blood from the heart to the lungs.
Pulmonary artery
Pulling the diaphragm downward causes this to happen.
What is air enters the lungs?
These need host cells to reproduce.
Viruses
These cells engulf pathogens.
Macrophages
TRIPLE JEOPARDY: This structure changes shape to focus images.
Lens
The electrical signal of the heart starts here.
What is the SA node?
Normal oxygen saturation range measured by pulse ox.
What is 95–100%?
Misfolded infectious proteins.
Prions
DOUBLE JEOPARDY: These cells present antigens to activate immunity.
Dendritic cells
Converts light into nerve signals.
Retina
This wave on an EKG represents ventricular depolarization.
What is the QRS complex?
TRIPLE JEOPARDY: Vital Capacity equals these three volumes added together.
What are TV + IRV + ERV?
Parasitic worms are called this.
Helminths
Cells that make antibodies.
B cells
Controls pupil size.
Iris
Formula used to compare ankle and arm systolic pressure.
What is ABI (Ankle-Brachial Index)?
Fluid in the alveoli causing poor diffusion is called this.
What is pulmonary edema?
This deadly condition occurs when infection triggers an extreme immune response.
Sepsis
Type of immunity with memory and specific targeting.
Adaptive immunity
Carries visual signals to the brain.
Optic nerve
