I HOPE YOU REMEMBER THIS...

LIVING THINGS

All you can see on Earth can be...

NON-LIVING THINGS

types

What's the difference?...

types

Animals Plants Fungi Microorganisms Bacteria Protista

YES!

Natural Artificial Are they born? Do they grow? Do they die?

NO!

Do they carry out vital functions?

LIVING THINGS KINGDOMS ANIMALS

PLANTS

FUNGI

MICROORGANISM (= Bacteria & Protista)

HUMAN BEING belongs to the Animal Kingdom. There are different races (black, caucasian (white)...) and two sexes (male and female). Our skin and some physical characteristics can be different but we all are equal and we have the same rights and duties. We also share the same characteristics and functions as the rest of living things: - We are born, grow and die. - We carry out vital functions to survive

Our body is an ORGANISM: It's made up of many different parts (systems)

We're living things

Complex forms of life that carry out several vital functions Our body perform different actions to keep alive (nutrition, etc.)

J.C. Brazo, El Tomillar

OUR BODY (organism) is made up of different parts (up to 10 body systems) Examples

CELLS are the smallest part of living things. The basic unit of life.

Not all our cells are the same. Different body parts are made up of different types of cells

J.C. Brazo, El Tomillar

Science 6th, unit 1

Sept 14

TISSUES are group of cells of the same type

Example: Stomach tissue is made up of stomach cells.

J.C. Brazo, El Tomillar

ORGANS are made up of group of tissues of the same kind

Example: The STOMACH is an organ made up of stomach tissue.

J.C. Brazo, El Tomillar

Sept 14

SYSTEMS are group of organs that work together to perform the same function in our body.

liver large intestine

stomach pancreas small intestine

Example: The DIGESTIVE SYSTEM carries out the function of digestion. It's made up of different ORGANS (stomach, intestines...) that work together for DIGESTING FOOD.

Our body is also called "

ORGANISM"

It's defined as: "An individual form or life, formed by SYSTEMS and other parts, that work together to carry out several LIFE PROCESSES"

SYSTEMS carry out LIFE PROCESSES

Reproductive and Endocrine Systems are different in male and female organisms

http://www.bbc.co.uk/bitesize/ks3/science/organisms_behaviour_health/life_processes/activity/

Some LIFE PROCESSES have several SYSTEMS involved in them. Can you guess any example?

J.C. Brazo, El Tomillar

Sept 14

The process that provides living organisms with nutrients that they use for growth, metabolism, and repair themselves.

PROCESS OF NUTRITION several systems take part in it

DIGESTIVE CIRCULATORY RESPIRATORY SYSTEM SYSTEM SYSTEM It changes food It moves into nutrients nutrients around all the body and picks up waste substances

It takes oxygen and releases carbon dioxide

EXCRETORY SYSTEM It eliminates other substances that are produced during the process of nutrition

STAGES OF NUTRITION: ingestion, digestion, absorption, transport, assimilation, and excretion

J.C. Brazo, El Tomillar

Science 6th, unit 1

Sept 14

Nutrients

-Vitamins & minerals -Carbohydrates -Proteins -Fats

FOOD is transformed by the DIGESTIVE SYSTEM into NUTRIENTS The digestive system is a long tube where digestion takes place

step 1: The TEETH crush food and the TONGUE mixes food with saliva that comes from your SALIVARY GLANDS and pushes it to the throat

produce saliva that the tongue mixes with food

J.C. Brazo, El Tomillar

Science 6th, unit 1

step 2: The food passes through the the OESOPHAGUS to the stomach

J.C. Brazo, El Tomillar

Science 6th, unit 1

Sept 14

step 3: After the oesophagus, the food reaches the STOMACH. Gastric juices break down food into a liquid.

J.C. Brazo, El Tomillar

Science 6th, unit 1

Sept 14

step 4: The food passes through the SMALL INTESTINE. Once food is transformed into nutrients, they are absorbed through the walls of the intestine liver

pancreas

Juices from these organs finish the process of extraction of NUTRIENTS from food

J.C. Brazo, El Tomillar

Science 6th, unit 1

Sept 14

step 5: After the small intestine, the LARGE INTESTINE processes non-digested food. It is in charge of absorbing liquids and turns the non-digested food into faeces, that are expelled outside through the anus

anus
