3.1 Organ systems

Learning goals

I can....

• describe how organs work together in organ systems
• list the organs belonging to the different organ systems
• describe the general function of each organ in the different organ systems

Key words

• Organ systems
• Digestive system
• Enzymes
• Skeletal system
• Respiratory system
• Muscular system
• Nervous system
• Reproductive system
• Circulatory system

Digestive System

Breaks food down so it is small enough to be absorbed into your blood. 

Your body does this with the help of enzymes.

Organs: stomach, liver, large intestine & small intestine

rectum

liver

mouth

stomach

oesophagus

large intestine

small intestine

Skeletal System

Provides:

- support

- movement

- protection

- blood cell production 

Organs: skull, pelvis, ribs, vertebrae

Respiratory System

Provides:

- ventilation

- gas exchange

- respiration

Organs: lungs, nose, mouth, windpipe

Muscular System

Provides:

- support 

- movement

muscles can only contract or relax, they work in antagonistic pairs

Organs: biceps, triceps, hamstrings

Reproductive System

Provides:

- Reproductive hormones

- Reproductive cells

These are different for both male and females. 

Organs: ovaries, uterus, testicles & penis

Nervous System

Provides fast communication in your body by electrical signals. 

Organs: brain, spinal cord, nerves (neurones) and senses. 

Circulatory System

Provides your body with the transport of oxygen and nutrients around the body. 

Organs: heart, veins, arteries and capillaries 

Overview organs (sheet year 4)

1) Trachea --> transport air

2) Lungs --> breathing

3) Heart --> pumping blood

4) Liver --> confer nutrients, filters blood and detoxicification

5) Stomach --> mix and break down food

6) Large intestine --> Absorb water and salt

7) Small intestine --> break down nutrients

8) Esophagus --> transports food to the stomach

9) Spleen --> stores and filters blood

10) Kidney --> Remove waste and filter blood

11) Bladder --> Storage of urine
