HEARTY TERMS
Blood vessel that carries blood away from the heart.
What are arteries?
With this pair of organs, the right one is larger than the left.
What are lungs?
It separates the right atrium from the right ventricle.
What is the Tricuspid valve?
The respiratory system is responsible for supplying this gas to the blood.
What is oxygen?
A disease characterized by spasm of the smooth muscles that line the respiratory system and an over secretion of mucous.
What is asthma?
The heart is made up of this specialized muscle tissue, also known as cardiac muscle.
What is myocardium?
This area of the respiratory system is composed of all the structures that convey air from outside the body through to the lungs.
What is the conductive zone?
This tool helps massage blood in veins back to the heart.
What is a Skeletal Muscle Pump?
This muscle, that separates the thoracic and abdominal cavities, plays an integral role in the process of inspiration and expiration.
What is the diaphragm?
The gradual narrowing of coronary arteries due to the accumulation of cholesterol (plaque) on the lining of the blood vessel.
What is atherosclerosis?
The heart's pacemaker.
What is the Sinoatrial Node (SA Node)?
The movement of gas from an area of high concentration to low concentration.
What is diffusion?
A trained individual might have one of 50 beats per minute.
What is Resting Heart Rate?
This must exist in order for diffusion to occur.
What is a concentration gradient?
Individuals with this disease cannot perform simple everyday tasks without experiencing dyspnea.
What is COPD (Chronic Obstructive Pulmonary Disease)?
Often represented by the letter 'Q', it is the volume of blood that is pumped out of the heart in one minute.
What is cardiac output?
The exchange of gases at tissue level.
What is internal respiration?
These blood vessels carry deoxygenated blood away from the heart and towards the lungs.
What are pulmonary arteries?
The average person has about 300 million these, enough to cover an entire tennis court.
What are alveolar sacs?
Someone with a consistent blood pressure reading of 140/90 or higher is said to have this.
What is hypertension?
The system of vessels that supply essential materials via blood to the heart itself.
What is coronary circulation?
The process is which lactate levels begin to accumulate rapidly in the blood.
What is Onset Blood Lactate Accumulation (OBLA)?
This specialized protein facilitates the transport of O2 in red blood cells.
What is Hemoglobin?
The size of the concentration gradient and the thickness of the barrier between two areas are both examples of this.
What are factors that affect the rate of diffusion?
A trained individual will reach this steady-state plateau faster than an untrained individual.
What is oxygen deficit?
