What are the 11 body systems?
- Integumentary
- Cardiovascular
- Respiratory
- Digestive
- Urinary
- Muscular
- Skeletal
- Nervous
- Endocrine
- Reproductive
- Lymphatic+ immune
What are the components of the integumentary system?
Skin, hair, nails, sweat + oil glands
Give 3 functions of the integumentary system?
protection, temperature regulation, eliminating waste
What are the components of the skeletal system?
bones, joints, cartilage
What are the functions of the skeletal system?
- Support and protection
- Muscle attachments
- Houses cells that produce blood cells
- Stores minerals and lipids
What are the components of the muscular system?
skeletal muscle
What are the functions of the muscular system?
- Enables movement
- Stabilises body position (posture)
- Generates heat
What are the components of the cardiovascular system?
blood, heart, blood vessels
What are the functions of the cardiovascular system?
- Transport of substances
- regulation
- defence against disease
What are the components of the lymphatic+ immune system?
lymphatic fluid, lymphatic vessels, lymph nodes, bone marrow, spleen, thymus, tonsils
What are the functions of the lymphatic
+ immune system?
- returns proteins and fluid to blood
- carries lipids from GI tract to blood
- protects against disease and cancer
What are the components of the endocrine system?
hormone producing glands
What are the functions of the endocrine system?
- coordinates body functions
- releases hormones from glands
What are the components of the nervous system?
Brain, Spinal cord, nerves and special sense organs such as eyes and ears.
What are the functions of the nervous system?
- Generation of nerve impulses for regulation of body activities
- detects and responds to stimuli
- initiates muscle contraction/ gland secretion
What are the components of the respiratory system?
The nose, pharynx, larynx, trachea, bronchi, lungs with their alveoli, diaphragm and muscles surrounding the ribs.
What are the functions of the respiratory system?
gas exchange, regulation of blood pH, voice production,
What are the components of the digestive system?
mouth, pharynx, esophagus, stomach, small + large intestine, salivary glands, gallbladder, liver, pancreas
What are the functions of the digestive system?
- physical and chemical breakdown of food
- absorbs nutrients
- eliminates solid waste
What are the components of the urinary system?
kidneys, ureters, bladder, urethra
What are the functions of the urinary system?
Eliminates wastes,
Regulation of blood volume and pressure,
stimulation of RBC (Red Blood Cell) formation,
control of fluid electrolyte
acid-base balance,
What are the components of the reproductive system?
female: ovaries, uterus, fallopian tubes, vagina
male: testes, epididymis, vas deferens, penis
What are the functions of the reproductive system?
- gamete production
- hormone release
