A body system is fundamentally made up of various organs and tissues that function collaboratively to facilitate a shared bodily process. The body systems consist of the following:
Circulatory system - involved in the blood circulation
Digestive system - responsible for food particle breakdown
Skeletal system - consists of bone structures that form our body's framework
Nervous system - comprises nerve cells that react to various stimuli
Respiratory system - manages the intake of oxygen and the expulsion of carbon dioxide.
In trees and other plants, the presence of a cell wall gives the organism a protective barrier, contributing to its stiffness and rigidity, whereas animals lack this structure, allowing for greater movement.
