LO3 Recap

Learning Objectives

• Recap LO3

• RAG rate LO3 topics

• Revise red rated topics

LO3: Biological Systems

• Skeletal System

• Endocrine System

• Nervous System

• Circulatory System

• Respiratory System

• Make sure you have your notes for all systems!

Poll

Please RAG rate the skeletal system

This includes: bone structure and function, joint structure and function (movement), muscle structure and function.

• Red

• Amber

• Green

Bones

• Bone marrow - produces RBCs

• Spongy bone - lightweight

• Compact bone - forms outer layer of bones

Multiple Choice

Which part of the bone forms the outer layer?

• Spongy

• Compact

• Marrow

Open Ended

How many joints can you remember?

Hint: You will be assessed on 5!

Joints

• Fibrous

• Hinge

• Ball and socket

• Pivot

• Gliding

• Which joint is shown in the x-ray?

Multiple Choice

Which type of joint is the shoulder joint?

• Ball and socket

• Pivot

• Hinge

Quiz Hint

• You need to be able to identify the 5 joints from photos and select the correct type of movement.

• E.g. A hip is a ball and socket joint. The movement is rotation.

Muscle types

Muscles

• Links to LO1

• You need to know the structure and function of cardiac, skeletal and smooth muscles

• We looked at this in our lesson on tissue types

Cardiac Muscle

• Structure: striated with fibres branching and connecting via discs

• Function: pump blood through the heart

Skeletal Muscle

• Structure: striated muscles - bundles of long cells making up fibres

• Function: movement of skeleton

Smooth Muscle

• Structure: spindle-shaped cells, no cross striations

• Function: move food through stomach and lines tubes within the body

Poll

Please RAG rate the endocrine system

This includes: endocrine gland locations and functions

• Red

• Amber

• Green

Endocrine glands

Poll

Please RAG rate the nervous system

This includes: CNS (brain and spinal cord) and PNS (nerves) structure and functions

• Red

• Amber

• Green

Nervous System

• CNS

• PNS

• Quiz hint - you need to know the function of the brain, spinal cord and PNS!

Poll

Please RAG rate the circulatory system

This includes: heart structure, blood vessels structure and functions

• Red

• Amber

• Green

Circulatory System

• You need to be able to label the heart and blood vessels

• Functions of the blood vessels (vein, artery, capillary)

Poll

Please RAG rate the respiratory system

This includes: lungs and respiratory structures and their functions

• Red

• Amber

• Green

Respiratory System

• You need to be able to label a diagram like this

• And, know the function of each!

Remember, you did a word sort on this!
