Cardiovascular
These "delivery" vessels carry blood away from the heart.
What are Arteries?
The primary organs of the respiratory system where gas exchange occurs.
What are the Lungs?
This gas is taken up from the air into the blood during gas exchange.
What is Oxygen?
The number of times the heart beats per minute is referred to as...
What is Heart Rate?
This "Master System" uses electrical signals to tell the heart to beat faster or slower.
What is the Nervous System?
This muscular organ acts as a double pump, moving blood to the lungs and the rest of the body.
What is the Heart?
The dome-shaped muscle at the bottom of the chest that controls breathing.
What is the Diaphragm?
This waste gas is removed from the blood and exhaled.
What is Carbon Dioxide (CO_2)?
The amount of air moved in or out of the lungs during a single normal breath.
What is Tidal Volume?
This system provides structure, protection, and blood cells for the body.
What is the Skeletal system?
The liquid portion of blood that carries nutrients, hormones, and waste.
What is Plasma?
Often called the "windpipe," this tube connects the larynx to the bronchi.
What is the Trachea?
At the tissue level, oxygen moves from the blood into these.
What are Cells (or Myocytes/Muscles)?
This is the volume of blood pumped by the heart in one single contraction.
What is Stroke Volume?
This system uses hormones like Adrenaline to regulate body functions.
What is the Endocrine System?
These tiny, thin-walled vessels are where the actual exchange of nutrients and gasses happens.
What are Capillaries?
When the diaphragm contracts and moves downward, this happens to the lungs.
What is Inhalation (or filling with air)?
This device is used to measure things such as respiration rate, tidal volume, inspiratory volume, etc.
A typical resting heart rate for a healthy teenager usually falls in this range.
What is 60–100 beats per minute?
The study of how the human body responds and adapts to physical activity, both in the short term (acute) and over time (chronic), focusing on improving health, performance, and managing diseases through tailored exercise interventions.
What is Exercise Physiology?
These blood components contain hemoglobin and are responsible for transporting oxygen.
What are Red Blood Cells (Erythrocytes)?
These microscopic air sacs are the specific site where oxygen enters the blood.
What are Alveoli?
This is the specific molecule in red blood cells that "grabs" oxygen in the lungs.
What is Hemoglobin?
Total blood pumped per minute, calculated as
Q = HR * SV
What is Cardiac Output?
Wolf's law says this structure adapts to the stress placed on it.
What is bone/skeletal?
