Functions Flashcards
Integumentary System
- Provides protection
- Regulates body temperature
- Excretes salts and urea through perspiration
- Generates vitamin D
- Senses pain, cold, temperature and pressure
Muscular System
- Movement and support
- Maintain posture
- Produce heat
Skeletal System
- Provide support and protection
- Participates on movement and locomotion
- Provides storage for minerals
- Produces blood cells
Nervous System
- Sensory receptors release information about changes in and around the body
- Controls activity of muscles and glands
- Controls consciousness, intelligence and memory
Cardiovascular System
- Pumps blood to distribute hormones and nutrients and gases
- Removes waste
Lymphatic System
- Returns fluid leaked from the blood bank to the blood vessels
- Cleans and disposes of debris in the lymphatic system
- Provides surveillance sites for immune cells
Respiratory System
- Site of gas exchange in the body
- Oxygen is absorbed into the bloodstream whilst carbon dioxide is removed
Endocrine System
- Produces hormones
- Regulates, coordinates and controls a number of body functions
- Controls moods, growth and development and metabolism
Urinary System
- Filters out excess fluid and other substances from the bloodstream
- Maintains the body’s water and electrolyte balance
- Regulates the acid base balance of the blood
Reproductive System
- Produces the sperm and oocyte
- Produces sex hormones
Digestive System
- Digests and absorb nutrients from food ingested
- Removes undigested food
Glucose
To produce energy
Glycogen
To break down to release glucose when blood glucose levels decrease allowing for an increase in energy
Enzymes
Facilitate and accelerate biochemical reactions in the body
Structural Proteins
Provide support and shape to cells and tissues
Transport Proteins
Move substances within cells or transport them across cell membranes
Hormonal Proteins
Help coordinate certain bodily activities by acting as messenger proteins
Contractile Proteins
Involved in muscle contraction and movement
Antibodies
Key components of the immune system, defending the body against pathogens
Triglycerides
- Store energy
- Provides insulation
- Protect
Phospholipids
Maintains protection through cell membranes
Steroids
- Growth
- Development
- Homeostasis
- Reproduction
Variable Stimulus
Produces the change in variable
Receptors
A type of sensor that monitors the stimulus and sends information to the control centre when there is a change
Afferent Pathway
Brings information from the receptors to the control centre
Control Centre
Interprets information from the receptor and compares the given level to the set point.
Set Point
The range or value of what the variable should be
Efferent Pathway
Sends information from the control centre to the effector
Effector
Provides the response to reduce the effect of the stimulus and return it’s variable back to homeostatic level
Carbohydrates
To store and provide energy
