PHYSIOLOGY
Task 1

Role of respiratory system to
carry out functions
 Responsible for supplying atmospheric oxygen to
body
 Expelling carbon dioxide and other gaseous waste.
 The organs of the system are lungs, nose and
trachea.
 The air enters from nose and reaches to lungs
through trachea.
 Trachea filters the air and sends it to lungs.
 Lungs breathe in oxygen and are transferred to all
body parts.
 The carbon dioxide and other waste gases are
released from body through lungs.

Role of digestive system to
carry out functions
 The group of organs that work together
so as to convert food into energy.
 It then further provides basic nutrients
that are used to feed the entire body.

Role of circulatory system to
carry out functions
 consists of heart, blood and network of
blood vessels like arteries, veins,
capillaries.
 It transports oxygenated blood to all the
parts of the body.
 it also circulates nutrients, hormones and
cellular waste other than oxygenated
blood throughout the body.

Interactions among body systems to
facilitate body functions and growth
 Human body systems in order to grow
and perform life processes work jointly at
the biological level.
 The digestive system, respiratory and
cardiovascular system coordinates to
carry out body functions in an integrated
manner.
 They interact with the help of cellular
communication.

 For instance: When the demand for energy
increases in body, then food is digested so as
to produce energy through digestive system.
 Circulatory system function along with
respiratory system that inhale atmospheric
oxygen.
 These blood transports oxygen to the heart
where it pumps it and circulates throughout
the body with the help of blood vessels. I
 n this manner, body systems function together
to meet the demand for oxygen in the body.
