Organ system - CORRECT ANSWERS Integrated collection of organs in the body that
work together to perform a function. Organ systems contribute to at least 1 of 4 vital functions
of life.
Four vital functions of life - CORRECT ANSWERS 1) exchange with the environment 2)
transport fluid and materials throughout the body 3) provide structure, support, protection and
movement 4) regulate and control processes
Exchange with environment - CORRECT ANSWERS To sustain life, body must take in
oxygen and nutrients and release carbon dioxide and other wastes into the environment. The
respiratory and digestive systems are the primary organ systems that provide these exchange
functions.
Fluid transport - CORRECT ANSWERS Distributes oxygen and nutrients to cells. It is the
cardiovascular and lymphatic systems (made up of vessels) that provide this delivery. Urinary
system also helps regulate the level of fluids in other systems as well as removes waste (also
plays a role in exchange with environment)
Structure, support, protection and movement - CORRECT ANSWERS These systems
include integumentary system (skin is main organ), skeletal system and the muscular system
Control and regulation - CORRECT ANSWERS Nervous and endocrine systems are main
systems that provide communication and control among the body's organs and tissues.
Digestive system - CORRECT ANSWERS Organs of digestive tract extend in a roughly
superior to inferior direction from mouth to anus in the following order: mouth, esophagus,
stomach, small intestine, large intestine and anus

Stomach - CORRECT ANSWERS Muscular sac which contains glands that secrete
enzymes and acids that break down food.
Small intestine - CORRECT ANSWERS Digestion continues within the small intestine
with digestive juices that are produced by the pancreas, liver and intestinal walls
Large intestine - CORRECT ANSWERS Reabsorbs excess water and removes waste
from the body
Skeletal system - CORRECT ANSWERS Major structure of system include: bones,
cartilage, ligaments and tendons
Bones - CORRECT ANSWERS Major structures of the skeletal system that contain living
cells called osteocytes. Osteocytes allow bones to sense and respond to stress. The inorganic
matrix of the bone gives it rigidity and acts as a storage deposit for calcium and phosphorus.
Cartilage - CORRECT ANSWERS Firm, flexible and smooth connective tissue found at
the end of bones. This tissue protects bones and evenly distributed forces to the underlying
bone.
Ligaments - CORRECT ANSWERS Band-like elastic structures that surrounds joints to
hold them together. These structures connect one bone to another and allow movement in
specific directions.
Tendons - CORRECT ANSWERS Band-like structures that connect muscle or bone.
Most commonly classified as belonging to muscular system but also play a function in the
skeletal system. These structures generate tension and movement.

Hematopoiesis - CORRECT ANSWERS Process of creating new blood cells in the body.
Haematopoietoc stem cells (HSCs) reside in the medulla of the bone (bone marrow) and have
the unique ability to give produce all different blood cell types and tissues.
Collagen - CORRECT ANSWERS Collagen is the main structural protein found in bones,
muscles, skin and tendons. It is the main component of connective tissue.
Renal system - CORRECT ANSWERS Comprised of the kidneys, ureters, urinary bladder
and urethra.
Kidneys - CORRECT ANSWERS Main organs of renal system located against the
posterior wall of the abdomen. They serve as a filtration and reabsorption system, where
soluble substances are filtered and those the body needs to keep are reabsorbed. Wastes are
excreted via urine.
Ureters - CORRECT ANSWERS Duct through which urine passes from the kidney to the
bladder
Bladder - CORRECT ANSWERS Urinary or renal bladder stores the urine from the
kidneys
Urethra - CORRECT ANSWERS Duct or tube by which urine is conveyed out of the body
from the bladder. In males it also connects to the ductus deferens for the ejaculation of sperm.
Function of renal system - CORRECT ANSWERS Filters and adjusts composition of
blood and interstitial fluid by removing excess water, electrolytes, salt, acid and metabolic
waste via urine. The renal system controls body fluid volume, blood pressure, pH and
electrolyte balance.

Nervous system - CORRECT ANSWERS Divided into 2 functional parts 1) central
nervous system 2) peripheral nervous system
Central nervous system or CNS - CORRECT ANSWERS Processes incoming information
and initiates a response and is comprised of the brain and spinal cord
Peripheral nervous system or PNS - CORRECT ANSWERS Comprised of the cranial
nerves and spinal nerves, brings sensory information to or carries motor output from the CNS
to initiate a reaction. Contains 3 types of nerves 1) sensory 2) motor 3) mixed
Sensory nerves - CORRECT ANSWERS Carry sensory input to the brain or spinal cord
from the environment
Motor nerves - CORRECT ANSWERS Carry motor impulses from the brain or spinal
cord to the muscles or glands
Mixed nerves - CORRECT ANSWERS Have a combination of sensory and motor
neurons in one nerve
Neurons - CORRECT ANSWERS Specialized cells that carry signals via electrical
impulses. These are the basic functional units of the nervous system and release chemical
substances called neurotransmitters.
Neurotransmitters - CORRECT ANSWERS Chemical substance that transmits
information to other neurons, muscles or glands.
