Kinesiology
Definition of Kinesiology
the study of movement
Definition of the heart rate
the number of times a heart beats per minute
Definition of blood
a specialized body fluid
Main function of the lungs
to take in oxygen from the air and expel carbon dioxide, does gas exchange
Significance of Kinesiology
Relates to everything we do. From the way we move, our nutrition, how we think, and our daily lives depend on all the physical movement we do which is Kinesiology.
Function of the Heart
pump blood throughout the body, carrying oxygen and nutrients to organs and removing waste products
What are the Arteries
tube-like blood vessels that transport oxygen-rich blood from the heart to the rest of the body
Definition of ventilation
involves the mechanics of inhaling and exhaling
The popularity of Kinesiology
Increasing as people focus on improving their lifestyles. People are starting to recognize the connection between your body and overall health.
Definition of a Cardiac output
the product of heart rate (HR) and stroke volume (SV), measured in liters
What are the veins
blood vessels that carry deoxygenated blood from the body back to the heart
What does gas exchange rely on
concentration gradients of oxygen and carbon dioxide between the air in the alveoli and the blood in the capillaries
Kinesiology unique personal application
It has an immediate bearing on people's lifestyle and well-being. Helps everyone make good lifestyle choices and helps determine the future quality of your life.
Definition of the stroke volume
the volume of blood pumped out of the heart's left ventricle during each systolic cardiac contraction
Blood doping
form of doping in which the number of red blood cells in the bloodstream is boosted in order to enhance athletic performance.
Where does gas exchange happen
Happens at the alveolar-capillary membrane, where oxygen diffuses from the alveoli into the bloodstream and carbon dioxide diffuses from the blood into the alveoli
To when does Kinesiology date back to
Ancient Greece
Systolic and diastolic blood pressure
Systolic: The maximum pressure in the arteries when the heart contracts and pumps blood out.
Diastolic: The minimum pressure in the arteries when the heart relaxes and fills with blood.
Blood's four main components and functions
four main components: red blood cells- carry oxygen, white blood cells- fights infections, platelets- forms clots, and plasma- transport medium for platelets
How many alveoli are there
about 700 million
