Body Responses to Physical Activities and Physiology

Task 2 and 4

Normal body responses to everyday physical
activities

Contd...
 Oxygen demand increases in working muscles during
heavy exercises.
 Respiratory system functions very rapidly to meet the
demand.
 Breathing mechanism coordinates with cardiovascular
organs and connective tissues to supply oxygen

 Everyday running increases heart rate in body to pump the
blood quickly.
 Red blood cells carry oxygen from lungs to the muscles that
are involved in jogging.
 During rest, breathing rate is normal as the body is in the
resting phase.

Explanation of body responses by cellular and
tissue structure and physiology

Contd...
 While working out, the body demands more oxygen
 In absence of energy supply, the person may feel
exhausted due to increased level of chemicals like blood
lactate leading to low levels of blood pH.
 To maintain the energy levels in the body, adipose
tissue pay very critical role.
