METABOLIC PROCESSES

INVOLVED IN VARIOUS ORGAN

SYSTEMS

EARTH AND LIFE SCIENCE – Grade 11

DIGESTIVE SYSTEM

Involves physical digestion,

the breakdown of food into

smaller particles which occurs in

the mouth and stomach

Chemical digestion is the

breakdown of large molecules

such as protein, starch and fats.

CIRCULATORY SYSTEM

Transports blood from the

heart to the lungs, to oxygenate

blood.

Systematic circulation

carries oxygen – rich blood from

the heart to organs and tissues.

RESPIRATORY SYSTEM

Supplies body cells with

oxygen; carbon dioxide as waste

products.

The organs involve are

heart, blood vessels, blood and

lymph nodes.

EXCRETORY SYSTEM

removes waste from the

body

The organs functioning are

the kidneys, urinary bladder,

ureter and urethra.

NERVOUS SYSTEM

Regulates behavior,

maintains homeostasis, controls

sensory and motor functions.

Organs are spinal cord,

nerves and brain.

REPRODUCTIVE

SYSTEM

Involves the production of

new individuals.

Organs are testes and penis

in males and ovaries and uterus in

females.

ENDOCRINE SYSTEM

It regulates, coordinates, and

controls a number of body

functions by secreting chemicals

into the bloodstream. These

secretions help control moods,

growth and development, and

metabolism

MUSCULAR SYSTEM

This system is made up of muscle

tissue that helps move the body

and move materials through the

body. Quite simply, muscles move

you.

– Muscles are bundles of cells and

fibers that work in a simple way:

they tighten up and relax

SKELETAL SYSTEM

The skeletal system provides the

shape and form for our bodies in

addition to supporting and

protecting our bodies, allowing

bodily movement, producing

blood cells, and storing minerals.

This system consists of bones,

cartilage, and joints

IMMUNE SYSTEM

a collection of structures and

processes within the body — is to

protect against disease or other

potentially damaging foreign

bodies. When functioning

properly, the immune system

identifies a variety of threats,

including viruses, bacteria and

parasites, and distinguishes them

from the body's own healthy

tissue

INTEGUMENTARY

SYSTEM

This system consists of the skin,

hair, nails, and sweat glands. Its

main function is to act as a barrier

to protect the body from the

outside world.

– It also functions to retain body

fluids, protect against disease,

eliminate waste products, and

regulate body temperature.

This provides the shape and form for our bodies in

addition to supporting and protecting our bodies,

allowing bodily movement, producing blood cells, and

storing minerals.

Involves the production of new individuals.

Involves physical digestion, the breakdown of food into

smaller particles which occurs in the mouth and stomach

Regulates behavior, maintains

homeostasis, controls sensory and motor

functions
