Questions and 100% Complete
Solutions (Verified Answers)
Energy - ✔the ability to do physical work
Metabolism - ✔the sum of all chemical reactions in the body that either use or create energy
Homeostasis - ✔a state of balance and stability within the human body. The body's ability
to maintain an overall balance of metabolic processes to adapt to the changing environment
Adenosine triphosphate (ATP) - ✔the energy currency of the body. A chemical
compound made up of adenosine and three phosphate molecules
Creatine phosphate (CP) - ✔a high-energy chemical compound stored in the muscle cell.
With the aid of an enzyme called creatine kinase, CP splits to create ATP and provide energy
Lactate Threshold (LT) - ✔the point at which the lactic acid begins to accumulate in the blood.
anaerobic glycolysis - ✔this system provides fuel for up to 2 minutes at maximal intensity.
Anaerobic metabolism system - ✔one of the body's energy systems in which chemical
reactions take place in the absence of oxygen. Energy is created by the metabolism of
stored creatine phosphate, or glucose depending on the intensity of the activity.
Aerobic metabolism system - ✔one of the body's energy production systems in which
chemical reactions take place with oxygen. Energy is created by the metabolism of oxygen
and glucose, or oxygen and fatty acids, depending on the intensity of the activity.
,Work-to-rest ratio - ✔the systematic organization of the time spent between
exercise performance and rest during physical activity.
Energy continuum - ✔a bioenergetics concept that suggests that the energy systems in the
human body do not function on their own and are constantly working in conjunction with one
another.
Oxygen deficit/debt - ✔the cellular situation in which the body does not have the
required amount of oxygen to maintain homeostasis and meet the needs of the increased
level of activity
Excess post-exercise oxygen consumption (EPOC) - ✔the process by which the body
continues to take in extra oxygen post-exercise, to recover the cell and repay the oxygen
deficit that occurred while active
pulminary circulation - ✔the movement of deoxygenated blood from the body into the
right atrium and right ventricle of the heart.
systemic circulation - ✔the movement of oxygenated blood from the left atrium and the
left ventricle to the body tissues
atrium (atria) - ✔the two upper chambers of the human heart. The left atrium and the
right atrium receive blood returning to the heart through the veins
cardiac output (Q) - ✔the amount of blood that the heart ejects in one minute; the product
of heart rate and stroke volume, represented mathematically as Q=SVxHR
ventilation - ✔the exchange of air between the lungs and the atmosphere through
the contraction of relaxation of the diaphragm and intercostal muscles
,diffusion - ✔the passive mode of transportation used in the exchange of oxygen and
carbon dioxide in the lungs
blood pressure (BP) - ✔the measure of the force of blood exerted on the walls of the
veins and arteries of the heart
VO2max - ✔the maximal capacity of the body to transport and use oxygen during exercise.
Reflects a person's physical fitness.
Ventricle - ✔the two lower chambers of the heart, composed of the left ventricle and the
right ventricle. The ______ expel blood to the lungs and the body.
axial skeleton - ✔the portion of the skeleton consisting of the skull, spine, ribs and sternum
anatomical position - ✔a position where a person stands with arms at the sides, palms
facing forward.
appendicular skeleton - ✔the portion of the skeleton consisting of the upper and lower
limbs, the pelvic girdle, and the shoulder girdles.
synovial joints - ✔a common joint in the human body that connects two bones and allows
the movement of the bones associated with it.
anterior - ✔front of the body
posterior - ✔back of the body
medial - ✔body parts close to the midline
, lateral - ✔body parts away from the midline
Inferior - ✔when one body part is below another
superior - ✔when one body part is above another
dorsal - ✔the top of the foot
plantar - ✔the bottom of the foot
distal - ✔the end of a bone or muscle that is away from the body
proximal - ✔the end of the bone or muscle that is closest to the body
supine - ✔when the body lies face up
prone - ✔when the body lies face down
supination - ✔external movement; movement away from the midline of the body
pronation - ✔internal movement; movement toward the midline of the body
flexion - ✔bending at the joint so that the angle between the bones is decreased
extension - ✔straightening at the joint so that the angle between the bones is increased
