Individual Level| Chapter #1| Biology Class 9th | Umair Khan

Hello

Today we will talk about Individual level

in our previous lecture we studied the organ and organ system level
Lets talk about individual level in detail

Different organs and organ systems are organized together to form an individual level and individual is also called organism.

In organism, the functions, processes and activities of various organs and organ systems are coordinated.
And form an organism or individual
For example, when a man is engaged in continuous work like hard exercise,
in this hard exercise not only his muscles are working but also there is an increase in the rate of respiration and heart beat.
During exercise This increase in the rate of respiration and heart beat supplies more oxygen and food to the muscles
which they need for continuous work.
Thank u
