Cardio-respiratory system WHOLE UNIT

This pack contains revision resources for the whole of the A-level edexcel PE course specification for the cardio-respiratory system (1.2).

1.2.1 Knowledge, understanding and application of the anatomy and
physiology of the cardiovascular, circulatory and respiratory
systems in physical activity. Understanding of how they
function individually and in conjunction with each other.
1.2.2 The structure and function of the respiratory system to include
the larynx, pharynx, trachea, bronchus, bronchiole, alveoli.
1.2.3 The physiology of the respiratory system as a mechanical
process of ventilation (inspiration and expiration). The cause
and effect process, including the role of pressure gradients,
partial pressure (pp) and diffusion.
1.2.4 Respiratory values and capacities: tidal volume, inspiratory
reserve volume, expiratory reserve volume, residual volume,
vital capacity, inspiratory capacity, functional residual capacity,
total lung capacity.
1.2.5 The anatomical components and structure of the cardio vascular
system to include, the heart – atria, ventricles, valves, septum,
atrioventricular (AV) and sinoatrial (SA) nodes, myocardia –
blood, and blood vessels (arteries, veins, and capillaries).
1.2.6 The physiology of the cardiovascular system with regards to the
cardiac cycle, systemic and pulmonary circulation, venous
return, vascular shunting, heart rates, (resting, working,
maximum, heart rate reserve and recovery), stroke volume,
cardiac output, end diastolic and end systolic volumes.
1.2.7 Understanding of bradycardia, why it may be beneficial and
how, anatomically and physiologically, it may occur.
1.2.8 The cardiorespiratory and cardiovascular systems and how they
respond acutely, both structurally and functionally, to the stress
of warming up and immediate physical or sporting activity.
1.2.9 Understanding of what constitutes an unhealthy lifestyle and its
effects on the cardiovascular and cardiorespiratory systems.
