Interdisciplinary Aspects of Learning: Physics and Human Body

PART A: INTRODUCTION

Have you ever reasoned, what is happening in my body right now? I can bet you are thinking of
it, we call that body metabolism where food and fuel is converted energy to run body processes.
The transfer of energy from one part of the body to another is work, this introduces us to physics.
(Gaspard-Gustave Coriolis) physics is an interdisciplinary subject that is everywhere around us
including around or in the human bodies.
This paper will establish the relationship between physics and human anatomy with a greater
depth research on examples from our human bodies.
OVERVIEW OF PHYSICS
Physics is a natural science that involves study of matter and its behavior over periods applying
concepts and theories of energy and force. The main goal of physics is to understand behavior
even though it keeps on changing based on application becoming difficult to maintain a specific
definition, this is because ;new discoveries bring out new definitions. Physics has formed a basic
for all academic disciplines like biology, branches of mathematics and chemistry during the
scientific revolution (Dill, Ken, and Sarina Bromberg, 2010).
Physics has evolved from the traditional, classic to modern physics. The study of on bodies acted
by forced in motion was classified under mechanics, electromagnetism, thermodynamics and
optics, now we have moved to modern era where matter and energy behave differently under
certain measure or extreme conditions. This gave rise to atomic and nuclear technology as well
as particle accelerator applicability, Albert Einstein developed a classical work that replaced

the idea of just space and time to accurate descriptions of systems hence quantum physics as
established in max Planck’s solution.
Quantum physics is the theory of nature basically studies the behavior of energy at atomic and
sub-atomic particles which differs from classical physics which is associated with discrete
measurements. The theory is mostly applied in quantum chemistry, laser and superconducting
magnets, discussions on physical-biological phenomena is described using the concepts of the
chemical bond (called micro-molecule, DNA)
Many biological activities involve conversation of energy to useful chemical substances which
are naturally quantum like light absorption, vision and enzymatic reactions in transfer of
electrons, etc. explaining genetic mutations and development of diseases like cancer that might
be intuitive in many experiments dedicated to physics and biology.
OVERVIEW OF THE HUMAN BODY
Human body is composed of cell that make up tissues, a combination of tissues create organs and
systems that maintain body homeostasis and viability. Organs is a collection of cells that make
up a system to perform a specific function studied under human anatomy- the study of human
body structure.
The body has several anatomy regions; heart, brain, liver, hip point, stomach, lungs, kidney
among others. These vital organs create anatomy systems like cardiovascular system, digestive
system, reproductive system, nervous system, skeletal, urinary, endocrine system as well as
muscular system. The system performs specific functions (work) using the concepts of energy.

Tissues form an organized group of cells that work together, for instance the muscle tissue form
a group of cells that are able to move and contract, nervous tissue create a system of neutrons to
transmit information while connective tissue of...
