peripheral
detect :arrow_up: in arterial H+
#
adrenaline release
:arrow_up: ventilation
#
decreased affinity for oxygen
PCO2 :arrow_up:
rapid gaseous exchange
#
BPG :arrow_up:
to produce ATP
#
temperature :arrow_up:
due to exercise
#
pH :arrow_down:
transport of CO2 as bicarbonate and H+

expansion of thoracic cavity
assisted by accessory muscle

Anatomy of Circulatory System
to :arrow_up: efficiency
double circulatory system

stroke volume :arrow_up:
blood pressure :arrow_up:
kidneys
secrete EPO to generate more red blood cells
pressure receptors
detect changes
send impulses to medulla
sympathetic activation by medulla
sympathetic fibre
release adrenaline

Relationship Between Heart Rate and Breathing Rate
oxygen demand
circulatory system
return oxygenated blood to heart
transport CO2 to lung
respiratory system
:arrow_up: CO2 in blood
loads hemoglobins with oxygen
unloads carbon dioxide from blood
Electrocardiogram (ECG)
P, R, and T waves become taller
RR and QT interval, QRS complex shorten
ST segment upslopes
Islamization
Al-Quran
Az-Zariat (52 :21)
observe
The creation in ourselves
Hadith
"A strong believer is better and dearer to God than a weaker believer"
encourages
Muslim to be healthy
increases depth of breathing
increases breathing rate
cardiac output increase
