human as complex organism

Human areComplex Organism

Why human being are complex organisms ?Let’s learn it together right now!

• Human beings are complex and special organisms.

• A complex organation of cells is in the human body.

• In addition, human beings are more intelligent than any others living things on Earth. Such as plants and animals.

• Can think to solve problem, can imagine, can create, can learn from experience and use languages are the characteristic of human beings.

The ability to do these makes us very special compared to others organisms.

A. The various types of cells which are

specialised to perform specific functions.(i) Reproductive cells

- SPERM CELL & EGG CELL.

- It produces offspring.

(ii) Muscle cells

It contract and relaxes to enable the arms and legs to move.

Muscle cells form muscles that enable us to move.

(iii) Epithelial cells

Epithelial cells form a layer to protect the cells below them.

(iv) Nerve cells

Nerve cells carry impulses to different parts of body.

It receives and sends messages to all part of our body.

(v) Red blood cells

Red blood cells can carry or transport oxygen to different parts off our body.The picture above this shown the normal

amount and Anemic anount of red blood cells.

(vi) White Blood Cells

White blood cells kill or destroy the bacteria that get inside to our body.

It also protect the body from infections.

(VII) BONE CELLS

Bone cells make up the bones that protect and support our body.

CELL ORGANISATION

Simple Complex

CELL

TISSUE

ORGAN

SYSTEM

ORGANISM

Basic unit that makes up human body.

Made up of the same type of cells that work together to perform a function.

Made up of different tissues that work together to perform a function.

Made up of different Made up of different organs that work together to perform a function.

Made up of different systems that work together.

THE IMPORTANTANCE OF CELL ORGANISATION IN THE HUMAN BODY

The importance of the organization of cells into organs and systems is that once cells are organized in this way, more complicated, higher-order forms of life are possible. Single-celled life, like the amoeba. It is very basic.

To develop more complicated, higher-order forms of life, cells must be able to group together to form tissues and organs.

In this fashion cells give up the questionable autonomy that the simple amoeba posses to become part of a larger system in which cells "differentiate" to take on different jobs in a larger system of cells, becoming organs, thus making worms, fish, snakes, birds, cats, and people possible.

VARIOUS SYSTEMS IN THE HUMAN BODY

SYSTEM FUNCTION

SKELETAL SYSTEM Support The Body.

Protects Our Organs.

Enable Body Movement.

BLOOD CIRCULATORY SYSTEM Transport Oxygen, Food Substances, Carbon Dioxide And Excretory Products In Our Body.


SYSTEM FUNCTION

MUSCULAR SYSTEM Moves Arms & Legs.

NERVOUS SYSTEM Coordinates All The Body’s Activities.

Responds To Sensation From The Surroundings And Sends Impulses from one part of our body to another.


SYSTEM FUNCTION

DIGESTIVE SYSTEM Break Up Food Into Simpler Form So That Nutrients Are Absorbed Easily By The Body.

EXCRETORY SYSTEM Removes Excretory Waste Such As Urea From Our Body.


SYSTEM FUNCTION

REPRODUCTIVE SYSTEM Produces Reproductive Cells

Produces young ones for the next generation.

MALE : Produces SPERMS.

FEMALE: Produces OVA.

VARIOUS SYSTEMS IN

THE HUMAN BODY

SYSTEM FUNCTION

RESPIRATORY SYSTEM Inhales Oxygen And Exhales Carbon Dioxide And Water Vapour From Our Body.

WHAT WILL HAPPEN IF ONE OF THE SYSTEMS FAILS TO FUNCTION??

If one or more system fails to function the other system starts to compensate by working harder. So it is important to be

checked and evaluated by your medical professional, so that proper treatment and care can be provided. Our body is very complex and wise in recognizing if there’s something went

wrong, but sometimes we will tend to ignore it.
