Anaerobic work refers to exercise that ............................................................................................
Examples
The aerobic system refers to three systems in order to ensure constant distribution of oxygen to the muscles during exercise, the
heart, the vascular and the respiratory systems.
Heart’s conduction system linked to the cardiac cycle
The heart has a dual-pump action with two separate pumps that work simultaneously to pump blood to two different destinations.
The right side pumps _______________________ blood towards the lungs
The left side pumps ________________________ blood towards the rest of the body
Label the heart
Relationship between and resting values of Heart Rate, Stroke Volume & Cardiac Output
Heart Rate (HR)
The number of times the heart
beats per _______________
Stroke Volume (SV)
The volume of blood ejected
from the heart per _________
The average resting heart rate
is ____________ bpm
The average resting SV is
approx __________ml
Cardiac Output (Q)
This is the volume of blood
ejected by heart ventricles in
______________ min
Q = SV x HR
EDV is volume of blood left in
ventricles at end of filling stage
ESV is volume of blood left in
ventricles at end of contraction
SV = EDV – ESV
Work it out
Using the calculations and information above, what would an average person’s cardiac output be at rest?
What is your cardiac output?

Gaseous Exchange
External Respiration (NB: sometimes called
pulmonary diffusion)
Where?
Movement
Why? 02
Why? CO2
Internal Respiration
Where?
Between alveoli air and blood in the alveolar capillaries
Between the blood in the capillaries and the tissue (muscle) cell walls
Movement
O2 diffuses into tissues; CO2 diffuses into blood
O2 in alveoli diffuses into blood; CO2 in blood diffuses into alveoli
Why? – 02
PP of O2 in alveoli is higher than the PP of O2 in the blood so O2 diffuses into the blood
PP of O2 in blood is higher than PP of O2 in the tissues so O2 diffuses into the myoglobin
within the tissues
Why? – CO2
PP of CO2 in the tissues is higher than the PP of CO2 in the blood so CO2 diffuses from the
tissues into the capillary blood
PP of CO2 in the blood is higher than the PP of CO2 in the alveoli so CO2 diffuses into the
alveoli
