Organs
Systems
Tissues
These systems are related with...

Reproduction
Interaction and nutrition
A very easy one... check the true statement.
Cell, tissue, organ, organism
Cell, organ, system, organism
Cell, tissue, organ, system
Cell, tissue, organism, system
True or false... Cells that perform different functions form a tissue.
True
False
The nervous system sends messages from the....
Nerves
Cerebellum
Spinal cord
Brain
_______ collect information from our sense organs (eyes, ears, nose, tongue, skin)
The brain
Motor neurons
Sensory neurons
Spinal cord
To carry out the function of interaction...
Sense organs, circulatory system and locomotor system.
Sense organs, reproductive system and locomotor system.
Sense organs, nervous system and locomotor system.
Sense organs, muscular system and skeletal system.
What are the functions of the brain?
The brain receives and processes information received from sense organs.
The brain put in relation the locomotor system with the nervous system.
The brain connects the spinal cord with the sensory nerves.
The brain controls the sensory nerves and the information our body receives.
True or false... Motor nerves transmit messages, which are sent from the muscles , joints and skin, to our brain.
True
False
What is a neuron?
Neurons are star-shape cells with three different parts: cell body, axon and dendrites.
Neurons are parts of the sensitive nerves.
Neurons are tissues that make the brain and the spinal cord.
Neurons are in all sense organs.
An easy one... the five senses are:
Sight, hearing, taste, touch, smell
Eyes, ears, nose, tongue, skin
Eyes, hearing, taste, hands, nose
Sight, brain, taste, touch, smell
A set of tissues that are grouped together and perform the same function...
CELL
TISSUE
ORGAN
SYSTEM
Several organs that perform a function together form a system
TRUE
FALSE
…… is the smallest unit of life, because it performs the three vital functions: nutrition, interaction and reproduction
ORGAN
TISSUE
CELL
SYSTEM
UNICELLULAR organisms are composed of two or more cells grouped to form different levels of organisation
TRUE
FALSE
Arrange the levels of organisation, from the simplest to the most complex:
CELL - SYSTEM - ORGAN - TISSUE - ORGANISM
ORGAN - ORGANISM - CELL - SYSTEM - TISSUE
CELL - TISSUE - ORGAN - SYSTEM - ORGANISM
CELL - TISSUE - ORGAN - ORGANISM - SYSTEM
CHECK THE CORRECT SENTENCES
CELL is the first level of organisation. Cells from differents parts of the body come in varying shapes, according to their functions.
MUSCLE CELLS are flat, line certain areas of the body and form a barrier to insulate and protect it
NERVE CELLS are star-shaped; stablish a network of connections and then transmit information all around the body
EPITHELIAL CELLS are elongated. These cells and the tissues that they form, expand and contract to alows muscles to move
…… are changes that happen outside the body, in the environment. Our sensory organs capture these stimuli and send a message to the brain
EXTERNAL STIMULI
INTERNAL STIMULI
Where is the information fron external and internal stimuli processed?
IN OUR SENSORY ORGANS
IN THE RECEPTOR ORGANS
IN THE BRAIN
IN THE BODY
INTERACTION FUNCTION:
1) processing information
2) stimulus-sensation
3) response
TRUE
FALSE
