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
Components of the excretory system
Kidney, lungs and skin
Components of the circulatory system
Heart, veins and arteries
