Organisation of human body Flashcards
Integumentary system and functions all starting with “S”
protective out-layer of body (skin) and lines hollow organ
- sebaceous glands lubraicate
- sweat glands thermoregulate
- sesnory receptors for touch
Three components of integumentary system and functions
Epidermis - Outlayer that has protective purposes
Dermis - Middle layer that encompases sweat glands, hair foliccles and nutrients that feed the epidermis
Hypodermis: Bottom layer connecting to inner tissue and stores fat
Muscular system and 3 of 4 components/functions
Axial - core muscles
aponeuroses - sheet like muscle that connects muscle to muscle
appendicular - Allow movement of limbs
Skeletal muscle function
Allow skeletal movment and controls entrances and exits of respitory and digestive system
skeletal system components and function
Axial - provide stability and structure for upper body
Appendicular - Limb strcuture
cartilage - allow cushioning between joints
bone - contain minerals like marrow and blood cells
Axial skeleton
Protects CNS and soft tissues of thorax
Appendicular skeleton
Provides internal support and posiitioning of limbs
Central nervous system
Includes brain and spinal cord for complex activity and control centre
Perihperhal nervous system
Includes everything else beside Brain and spinal cord - acts as an intermediate between CNS and body for special senses
endocrine system
Hormone producer
Thymus
Produces T cells - more important for kids than adults
Pituatry gland
Growth hormone and control centre
Thyroid gland
Produces and controls calcium levels
Pineal Gland
Internal biological clock
Kidney
pH, Calcium and blood pressure contorl
gonads
sexual reproductive organs
Pancreas
In endocrine - Glucose control
In digestive - enzymes and buffers to break down food
Acromegaly disease
Too much growth hormone resulting in gigantisism
Lymphatic system purpose
maintains fluid levels in our body tissues by removing all fluids that leak out of our blood vessels
Lymph nodes
Have immune system response by containing hormones (b and t cells) - can be found in tonsils
