FUNCTION
Pumps blood to and
from the heart to
supply oxygen to the
body.
STRUCTURES
•Blood
•Heart
•Arteries
•Capillaries
•Veins
How does this system relate to others?
Connected to almost all other
systems. Works very closely with
the respiratory system and the
immune system.
FUNCTION
Collection of glands
that secrete hormones
into the blood which
regulate growth,
development, and
homeostasis.
STRUCTURES
•Hypothalamus
•Pituitary gland
•Thyroid
•Adrenal glands
•Ovaries
•Testes
How does this system relate to others?
The endocrine system works closely with the
reproductive system, the digestive system and
the excretory system. Several hormones
originate in the brain, part of the nervous
system.
How does this system relate to
others?
The immune system
works closely with the
circulatory system
and the
integumentary
system.
FUNCTION
Protects the body from
pathogens.
STRUCTURES
•Thymus
•Spleen
•Lymph nodes
•Lymph vessels
•White blood cells
FUNCTION
Protects the body
from infection and
injury, regulates body
temperature.
STRUCTURES
•Hair
•Skin
•Nails
•Sweat glands
•Oil glands
How does this system relate to others?
The integumentary contains blood vessels
(circulatory system) and nerves (nervous
system) and works closely with the immune
system (helping keep pathogens out) and the
excretory system (excreting waste via sweat).
FUNCTION
The hard structure
that provides a frame
for the body of an
animal.
STRUCTURES
•Bones
•Cartilages
How does this system relate to others?
Muscular system – bones and muscles work
together for movement
Circulatory system and immune system – all
blood cells (red and white) are made in the bone
marrow
How does this system
relate to others?
The nervous system
works with many other
systems, but works most
closely with the:
Digestive system and
Muscular system to
coordinate movement
FUNCTION
The body's speedy,
electrochemical
communication system,
consisting of all the nerve cells
of the peripheral and central
nervous systems.
STRUCTURES
•Brain
•Nerves
•Spinal cord
FUNCTION
Creates movement,
regulates body
temperature and
protects the body.
STRUCTURES
•Muscles
•Tendons
How does this system relate to others?
Works closely with the:
Skeletal system – Supports the muscle
Circulatory – brings O2 to muscles and
waste products such as lactic acid away
Nervous – how muscles contract
How does this system
relate to others?
Muscular – contains
smooth muscle
Nervous – gets signals
that control the rate of
digestion
Circulatory – broken down
food travels through blood
vessels to cells
Endocrine – hormones
(ex. Insulin) control blood
sugar levels
FUNCTION
Breaks down food and
delivers the products
to the blood for
dispersal to the body
cells.
STRUCTURES
•Gallbladder
•Oral cavity
•Pancreas
•Esophagus
•Small intestine
•Stomach
•Large intestine (colon)
•Liver
•Rectum
How does this system relate to others?
Circulatory – waste products are
carried from the cells to the
kidney through blood vessels
Endocrine – hormones are sent
that control water levels and
homeostasis
Respiratory – expels toxic CO2
out of body
FUNCTION
Removes wastes from
the body and helps to
maintain water and
electrolyte balance.
STRUCTURES
•Kidneys •Urethra
•Ureters •Lungs
•Bladder •Skin
•Liver
How does this system relate to
others?
The reproductive system
works most closely with
the endocrine system
(hormones)
FUNCTION
Organ system which
functions in creating
offspring and
producing sex
hormones.
STRUCTURES
Males: Females:
•Penis
•Ovaries
•Testes •Uterus
•Vagina
How does this system relate to
others?
Circulatory – brings O2 to
the cells and CO2 back to
the lungs
Excretory – part of the
excretory system to get rid
of toxic CO2 from the body
FUNCTION
Responsible for gas
exchange.
STRUCTURES
•Lungs
•Bronchi
•Pharynx •Diaphragm
•Larynx •Trachea
