Body System - Lymphatic
Lymph fluid / capillaries / vessels / nodes / ducts / lymphoid tissue
Drains excess fluid
Removes cellular waste
Produces antibodies
Transports fats
Body System Urinary
Kidneys / Ureters / Bladder / Urethra
Removes waste products from blood
Eliminates waste (via Urine)
Controls body fluid balance, salt content and acidity
Body System - Integumentary

Absorbs nutrients from food
Eliminates waste (feaces)
Body System - Nervous
Central nervous system (brain, spinal cord)
Sensory neurones (sensation)
Motor neurones (movement)
Regulates & controls body functions - consciously and unconsciously (autonomic nervous system)
Maintains homeostasis (state of internal balance)
Body System - Muscular system
Muscles - skeletal / smooth / cardiac
Movement
Muscle tissue characteristics
Shorten / contract
Are elastic - can stretch & return to original state
Respond to nervous stimuli
Muscle tissue / smooth / voluntary
Controlled unconsciously & carries out functions not consciously controlled
Located in digestive system (stomach, oesophagus, intestines), blood vessels, bladder.
Works for long periods of time without tiring
Muscle Tissue - Voluntary / Skeletal
Consciously controlled - works with bones for movement
Can work very hard for short periods / tires easily
Muscle tissue - Cardiac
Found only in the heart
Contracts without nervous simulation
Works tirelessly throughout life
Trapezius
A large kite shaped
muscle that covers the
back and sides of the
neck, shoulders and
upper back
Elevates and depresses
the shoulders, also
draws the head
backwards
Rhomboids
In between the scapula
and thoracic vertebrae
Braces shoulder and
rotates scapula
Latissimus dorsi
Large muscle which
extends from the
thoracic and lumbar
vertebrae
Helps pull the body
upwards when climbing,
draws shoulders/arm
down and backwards
Errector Spinae
Runs down the length of
the vertebrae
Extends the spine and
holds the body upright
Pectorals
Cover the chest
Draws the arm and shoulder in towards the chest
Intercostals
In-between the ribs,
running obliquely
downwards
Muscle of respiration, used to increase the thoracic cavity when breathing normally
Rectus abdominis (6 pack)
Extends the whole
length of the front
of the abdomen & is
divided into 4 sections
Flexes the trunk forwards,
extends the spine and
maintains upright posture
Obliques (corset)
Extends laterally
from sides of the abdomen
Flexes the trunk, when acting
alone it twists the trunk
Diaphragm
Mid chest separating
the thoracic and
abdominal cavities
Muscle of respiration, flattens to increase the thoracic cavity when breathing in, causing the
ribs to rise
Quadriceps (rectus
femoris, vastus
lateralis, vastus
medialis and vastus
intermedius)
Front of thigh
Flexes the hip and
extends the knee
Adductors (longus,
magnus and brevis)
Inner thigh
Adducts the hip and
rotates the hip
Abductors (Tensor fascia latae)
Outer / lateral thigh
Flexes and abducts the
thigh
Sartorius
Crosses the front
of the thigh to
the inner knee
Flexes and laterally
rotates the hip joint,
used to sit cross legged
Tibialis anterior
Down the shin
On the lateral
side of the tibia
Flexion and inversion of
the foot (drawing sole
inwards)
Gluteals
Buttocks
Abducts and rotates
femur, extends the knee
Hamstrings
(biceps femoris,
semimembranosis
semitendonosis)
Back of thigh
Extends the hip and
flexion of the knee
Gastrocnemius
Back of calf
Flexes the knee and
the foot, used for
propelling the body
when walking
Soleus
Deep in the back of the
calf, below gastrocnemius
Flexes the foot
Deltoid
Caps shoulder
Lifts, extends, and
rotates the arm
Biceps
Front upper arm
Flexes the forearm
and turns palm
upwards
Triceps
Back upper arm
Extends the forearm
wrist flexors
Anterior forearm –
comprises of 3
muscles
Flexes the wrist,
drawing it towards the
forearm
Wrist extensors
Back of forearm –
comprises of 3
muscles
Extends and
straightens the wrist
and hand
Brachioradialis
Thumb side of forearm
Flexes the elbow
Brachialis
Front of lower
part of the upper
arm, crossing
the elbow
Flexes the forearm
Body systems = Skeletal system
Bones / Joints
Support / structure
Movement
Produces blood cells (red bone marrow)
Mineral deposit

Joints
Most body joints are synovial - contain synovial fluid
Several types of synovial joints - different planes of movement
Saddle joint
Thumb - rock back and forward and side to side (flexion and extension) but limited rotation.
Gliding joint
Wrists - bones move against each other freely with sliding and twisting movements.
Ball & socket joint
Hip & shoulder - wide range of movements including rotational movements. Allow you to swing your legs and arms in different directions.
Hinge joint
Elbow, knee - like a door – in one direction only.
Pivot joint
The neck - rotation around a central axis i.e. moving head from side to side.
Condyloid joint
Palm of hand, fingers & toes- side to side and front to back but can’t rotate
Fixed joints (fibrous)
joints of the skull which don’t allow any movement
Slightly moveable joints
joints of the spine only allow a small amount of movement - are connected by pads of cartilage
