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
Lymphatic vessels
pathway for lymphatic fluid (Lipids, fats) to travel through
Spleen
Englufs pathogens (Disease carrying hosts)
Cardiovascular system purpose
Transport of O2 and CO2 , regulation of water content and temperature
Heart
Pumps blood
Blood
Transports, O2, CO2, hormones, nutrients, removes wastes, thermoregulates, immune response
Cardiovascular vessels and function
Arteries - Carry blood from heart to capilleries
capilleries - Diffusion of blood and interstitial fluid (Fluid found around cells_
Respitory system purpose
Transfer of O2 and CO2 between blood and air
Order of air conduction to lungs
- Pharynx
- Larynx
- Trachea
- Bronchi
- Lungs
Trachea conducts air to … which does…
Bronchi which conducts air to lungs
Pharynx conducts air to .. which does
Larynx which has vocal cords and responsbible for vocalisaiton
Paranasal sinus/Nasal cavity
Detects smell
Lungs
Exchnage of O2 and CO2
Digestive system Components and functions
- Oral cavity - break down food
- Saliva - contain enzymes that break down sugars in carbs
- oesophagus - conducts food/liquid into stomach
- Stomach - acid/enzymes that break down food
- small intestine - contain enzyme hormones and buffers
6 onwards in seperate cards
Liver
Secretes bile and regulates nutrients in blood
Gallbladder
Concentrates bile
large intestines
waste removal
Urinary system purpose
urine control, blood regulation and blood cell production
ureters
Pathway for urine into bladder
bladder
stores urine before being expelled
Urethra
exit channel of urine
Male reproductive system components (memorable)
Testes - produce sperm
Penis/scrotum - reproduction tool
epidydimus
Sperm maturation
ductus deferens
sperm from epidydimus
seminal and prostate glands
seminal fluid
Female reproductive system components
Fallopian tubes - pathway for sperm and egg
vagina - reproduction tool with lubricant
Uterus - Womb for embryonic development
ovaries - oocytes and hormones
mammary glands
Part of female reproductive system providing nutrients to new borns (Modified sweat glands)
6 levels of strucutral organisation
- chemical
- organs
- organismal
- tissue
- cellular
- System level
Epithelial cells function
Cover body, line hollow organs and form glands for protection, filtration and absorption
Connective tissue function
Support, protect and bind
Muscle tissue function
contractile compartments for movement
nervous Tissue components and function
Neurons and neuroglia, for sensory and motor functions
