Body Systems: Responding to Change Flashcards
Main types of tropism
Photo, geo, hydro and thigmotropism
Tropism
Plant responses to stimulus
Positive Tropism
Growth towards a stimulus
Phototropism
Plant’s response to light
Phototropism
Plant’s response to light
Geotropism
Plant’s response to gravity
Hydrotropism
Plant’s response to water
Thigmotropism
Plant’s response to a solid surface
Homeostasis
The process of maintaining a stable internal environment
Stages of homeostasis
Change detected by receptor - Control centre determines the point the body needs to get back to - Effector carries out changes to stabilize the body - Body is stable
Types of body systems
Skeletal, digestive, respiratory, excretory and circulatory system
Endotherm
Animals that can maintain a constant internal temperature
Components of the skeletal system
Bones
Components of the digestive system
Mouth, oesophagus, stomach, intestines, rectum and anus
Components of the respiratory system
Windpipe, diaphragm and lungs
