Analyzing Functions & Interactions of Body's Key Systems

This report outlines the crucial roles of the respiratory, digestive, and circulatory systems in maintaining bodily functions. The respiratory system facilitates oxygen intake and carbon dioxide expulsion via the lungs, nose, and trachea. The digestive system converts food into energy and provides essential nutrients. The circulatory system, comprising the heart, blood, and blood vessels, transports oxygen, nutrients, hormones, and cellular waste throughout the body. These systems work in coordination, for example, when energy demands increase, the digestive system processes food, while the respiratory and circulatory systems collaborate to deliver oxygen to cells, ensuring the body's needs are met through integrated cellular communication.

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.
