| Question | Answer |
|---|---|
| What are the levels of structural organisation: | Organisation of the body is separated into six distinct levels. Each level is increasingly complex. |
| Name the six levels of structural organisation: | - Chemical level - Molecular level - Cellular level - Tissue level - Organ level - Organ system level - Organism level |
| What are the structures of the integumentary system? | - Skin - Hair - Sweat glands - Nails |
| What are the functions of the integumentary system? | - Protect against environmental hazards - Regulation of body temperature - Provides sensory information |
| What are the structures of the skeletal system? | - Bones - Cartilage - Ligaments - Bone marrow |
| What are the functions of the skeletal system? | - Support and protection for other tissues - Stores calcium and other minerals - Formation of blood cells |
| What are the structures of the muscular system? | - Skeletal muscles - Tendons |
| What are the functions of the muscular system? | - Movement - Protection and support for other tissues - Generates heat |
| What are the structures of the nervous system? | - Brain - Spinal cord - Peripheral nerves - Sense organs |
| What are the functions of the nervous system? | - Direct immediate responses to stimuli - Coordinates activities of other organ systems - Provides and interprets sensory information about external conditions |
| What are the structures of the endocrine system? | - Pituitary gland - Thyroid gland - Pancreas - Adrenal glands - Gonads (testes and ovaries) - Endocrine tissues in other systems |
| What are the functions of the endocrine system? | - Directs long-term changes in activities of other organ systems - Adjusts metabolic activity and energy use - Controls structural and functional changes during development |
| What are the structures of the cardiovascular system? | - Heart - Blood - Blood vessels |
| What are the functions of the cardiovascular system? | - Distributes blood cells, water, nutrients, waste, products, oxygen and carbon dioxide - Distributes heat and assists in control of body temperature |
| What are the structures of the lymphatic system? | - Spleen - Thymus - Lymphatic vessels - Lymph nodes - Tonsils |
| What are the functions of the lymphatic system? | - Defends against infection and disease - Returns tissue fluid to the bloodstream |
| What are the structures of the respiration system? | - Nasal cavities - Sinuses - Larynx - Trachea - Bronchi - Lungs - Alveoli |
| What are the functions of the respiration system? | - Delivers air to alveoli - Provides oxygen to bloodstream - Removes carbon dioxide from the blood stream - Produces sounds |
| What are the structures of the digestive system? | - Teeth - Tounge - Salivary glands - Pharynx - Oesophagus - Stomach - Small intestine - Large intestine - Liver - Gallbladder - Pancreas |
| What are the functions of the digestive system? | - Processes and digests food - Absorbs and conserves water - Absorbs nutrients - Stores energy reserves |
| What are the structures of the urinary system? | - Kidneys - Ureters - Urinary bladder - Urethra |
| What are the functions of the urinary system? | - Excretes waste products from the blood - Controls water balance by regulating volume of urine produced - Stores urine prior to elimination - Regulates blood ion concentration |
