cell organisations Flashcards
what are cells
The basic building blocks that make up all living organisms
When does differentiation occur
During the development of multicellular organisms
What do the specialise cells form and so on
Specialise cells form tissues which form organs which form organ systems
what do large multi cellular organisms have inside them
different systems for Exchanging and transporting materials
what are similar cells organised into
tissues
what is a tissue
a group of similar cells that work together to carry out a particular function
what are examples of tissues inside mammals
muscular tissues
glandular tissues
epithelial tissues
what are muscular tissues
tissues which contract to move whatever it is attached to
what are glandular tissues
tissues that make and secrete chemicals like enzymes and hormones
what are epithelial tissues
tissues which cover some part of the body, for example inside the gut
what are tissues organised into
organs
what is an organ group
different tissues that work together to perform a certain function
what tissues are the stomach made of
muscular tissues
glandular tissues
epithelial tissues
what do my muscle tissues in the stomach do
move the stomach wall to churn up food
what do glandular tissues in the stomach do
makes digestive juices to digest food
what do epithelial tissues in the stomach do
cover the outside and inside of the stomach
what are organs organised in to
organ systems
what organs are in the digestive system
glands
stomach
liver
small intestine
large intestine
what are the glands in the digestive system and what do they do
pancreas and salivary glands produce digestive juices
what does the stomach do
digest the food
what does the liver do
produce bile
what does the small intestine do
absorbs soluble food molecules
what does the large intestine do
absorbs water from undigested food leaving faeces
what do organ systems work together to make
entire organ systems
