Lesson 1- Introduction To Human Body Flashcards
Name the order of the levels of body structure ?
- Chemical level
- Cellular level
- Tissue level
- Organ level
- Organ system level
- Organismal level
Integumentary system
Consists of hair/nails/skin
Forms the external body covering (protects deeper tissues)
Synthesises vitamin D
Site of cutaneous receptors (pain, pressure etc.), sweat/oil glands
Skeletal system
Consists of bones and joints
Protects/supports body organs
Provides framework for muscle movement
Site where Blood cells formed
Store minerals
Muscular system
Consists of skeletal muscles
Allows manipulation of environment,
Locomotion,
And facial expressions
Maintains posture
Produces heat
Nervous system
Consists of the brain/sensory receptors/nerves/spinal cord/
Fast acting control system
Responds to internal/external changes by activating appropriate muscles and glands
Endocrine system
Consists of pineal gland/pituitary gland/thyroid gland/thymus/adrenal gland/pancreas/testes/ovaries
Cardiovascular system
Consists of heart and blood vessels
Blood vessels transport oxygen/co2/nutrients/waste etc. carrying blood
Heart pumps blood
Lymphatic system/ immunity
Consists of red bone marrow/thymus/lymphatic vessels/thoracic duct/spleen/lymph nodes
Picks up fluid leaked from blood vessels and transfers it back in
Disposes debris in lymphatic stream
Houses lymphocytes (WBC)
Respiratory system
Consists of nasal cavity/pharynx/larynx/trachea/bronchus/lung
Supplies blood with oxygen/ removes co2
Digestive system
Consists of oral cavity/oesophagus/liver/stomach/small I/large I/rectum/anus
Breaks down food into small absorbable units which enter the blood
Indigestible foodstuffs are eliminated as faeces
Urinary system
Consists of kidney,ureter,urinary bladder,urethra
Eliminates nitrogenous wastes from body
Regulates water, electrolyte and acid based balance of blood
Male reproductive system
Consists of prostate glands,ductus deferens, scrotum, penis, testes
Production of offspring
Testes produce sperm and male sex hormone
Ducts and glands aid in delivery of sperm to female reproductive tract
Female reproductive system
Consists of mammary glands (breasts), ovary, uterine tube, uterus, vagina
Ovaries produce eggs and female sex hormones
Structure serves as site of fertilisation and development of fetus
Mammary glands produce milk to nourish newborn
