GCSE PE - 7
- Heart
- Heart Rate
- (HR)
- The amount of
beats per minute.
- The amount of
beats per minute.
- (HR)
- Stroke Volume
- (SV)
- The amount of blood pumped by
the heart in one beat.
- The amount of blood pumped by
the heart in one beat.
- (SV)
- Cardiac Output
- (CO)
- The amount of blood
pumped by the heart in
one minute.
- The amount of blood
pumped by the heart in
one minute.
- (CO)
- CO = SV x HR
- Heart Rate
- Respiratory System
- Oxygen Debt
- The shortfall of oxygen to the body
after maximum effort/anaerobic
exercise, resulting in deep and
shallow breathing.
- The shortfall of oxygen to the body
after maximum effort/anaerobic
exercise, resulting in deep and
shallow breathing.
- Vital Capacity
- The maximum amount of air that
can be forcibly exhaled after
breathing in as much air as
possible.
- The maximum amount of air that
can be forcibly exhaled after
breathing in as much air as
possible.
- Tidal Volume
- The amount of air
breathed in or out at rest.
- The amount of air
breathed in or out at rest.
- Anaerobic
(without oxygen)
- Glucose + Oxygen >> Carbon
Dioxide, Water, Energy, Lactic Acid
- Glucose + Oxygen >> Carbon
Dioxide, Water, Energy, Lactic Acid
- Aerobic
(with oxygen)
- Glucose + Oxygen >> Carbon
Dioxide, Water, Energy
- Glucose + Oxygen >> Carbon
Dioxide, Water, Energy
- The
function is
to get
Oxygen
into the
body and
remove
Carbon
Dioxide
from the
body.
- Oxygen Debt
- Mechanism of Breathing
- Inspiration
- Our diaphragm
pull down.
- Our intercostal
muscles contract.
- Air pressure
is reduced.
- Air is sucked through
the tubes into our lungs.
- Our Chest Expands.
- Inhaled Air
- 79% Nitrogen, 20% Oxygen and a
trace amount of Carbon Dioxide.
- 79% Nitrogen, 20% Oxygen and a
trace amount of Carbon Dioxide.
- Inhaled Air
- Our Chest Expands.
- Air is sucked through
the tubes into our lungs.
- Air pressure
is reduced.
- Our intercostal
muscles contract.
- Our diaphragm
pull down.
- Expiration
- Our diaphragm relaxes.
- Our intercostal muscles relax.
- Our chest
becomes smaller.
- Pressure increases
on the lungs.
- Air is forced out.
- Exhaled Air
- 79% Nitrogen, 16% Oxgen
and 4% Carbon Dioxide.
- 79% Nitrogen, 16% Oxgen
and 4% Carbon Dioxide.
- Exhaled Air
- Air is forced out.
- Pressure increases
on the lungs.
- Our chest
becomes smaller.
- Our intercostal muscles relax.
- Our diaphragm relaxes.
- Inspiration
- Lactic Acid
- Lactic acid is a
bi-product of
exercise. A build
up of this can
inhibit performance
and cause pain,
discomfort and
fatigue.
- It occurs in the anaerobic
system because without the
presence of oxygen, 'Pyruvic
Acid' turns the 'Lactic Acid'.
- Cooling down properly
with stretching helps
the lactic acid be
removed and prevents
aching muscles after
the exercise.
- Lactic acid is a
bi-product of
exercise. A build
up of this can
inhibit performance
and cause pain,
discomfort and
fatigue.
