Human Body Systems Cards
Teacher Instructions: Print out these cards onto cardstock (in color, if possible). Print enough for
each pair of students to receive one set. Laminate, cut apart, and bag the cards.
ENDOCRINE SYSTEM
Made up of a series of glands that release
chemicals directly into bloodstream
Controls body through release of hormones
Hormones provide information to body cells
about metabolism, growth, development,
and behavior.
Works with the nervous system to maintain
homeostasis
Organs include: thyroid, pituitary gland, and
hypothalamus

EXCRETORY SYSTEM
Responsible for waste removal
Includes: kidneys, urinary tract, bladder,
ureters, and urethra
Kidneys filter blood to remove wastes from
it, helping to maintain homeostasis of body
fluids.
Kidneys also help control level of sodium
level in the blood.

INTEGUMENTARY SYSTEM
Main organ is the skin and covers body
surfaces
Flexible and responsive organ
Exterior layer of epidermis helps protect
from exposure to bacteria, heat, and
chemicals
Interior layer of epidermis has melanin to
help protect body cells from damage by
solar radiation
Helps maintain homeostasis by regulating
internal body temperature
Functions as a sense organ
Produces essential vitamins

NERVOUS SYSTEM
Includes: nerves, brain, and spinal cord
Relays information to and from skin and
skeletal muscles
Relays information to internal organs
Controls organs in times of stress and when
body is at rest
Basic structure unit is the neuron

MUSCULAR SYSTEM
Three types: skeletal, smooth, and cardiac
Smooth: involuntary; lines organs; and most
often squeezes to exert pressure on the
space inside the tube or organ it surrounds
in order to move material through it
Cardiac: involuntary; interconnected
network that helps heart contract efficiently
Skeletal: voluntary; attaches to and moves
bones
Able to contract to do work and move the
body

DIGESTIVE SYSTEM
Breaks down food you eat into molecules
that can be used as energy for your body
cells
Breaks down food both mechanically and
chemically
Includes: mouth, stomach, small and large
intestines, and esophagus

RESPIRATORY SYSTEM
Includes: mouth, nose, lungs, and
diaphragm
Involved in getting oxygen to your body
cells and removing carbon dioxide
Cleans the dirty air you breathe
Controlled partially by chemistry of the
blood

CIRCULATORY SYSTEM/
Includes: heart, veins, and arteries
CARDIOVASCULAR
SYSTEM
Veins carry blood to the heart.
Arteries carry blood away from the heart.
White blood cells: large; several types; all
have nuclei; defend body against disease
Red blood cells: transport oxygen and
some carbon dioxide; lack a nucleus;
contain hemoglobin
Platelets: cell fragments needed for blood
clotting
Plasma: liquid; has proteins; transports red
and white blood cells, platelets, nutrients,
enzymes, hormones, gases, and inorganic
salts

REPRODUCTIVE SYSTEM
Includes: testes and ovaries
Controlled by hormones
Males produce sperm via meiosis.
Females produce eggs via meiosis.
Events in meiosis help maintain
chromosome number in humans.

IMMUNE SYSTEM
Variety of white blood cells to defend
against invasion of pathogens
Skin, mucus, oil, sweat, tears, and saliva
also work to prevent pathogens from
entering body
Consists of lymphatic vessels, lymph
nodes, tonsils, spleen, and thymus

SKELETAL SYSTEM
Includes: bones, ligaments, tendons, and
joints
Produces red blood cells in marrow
Stores minerals and fat
Allows for body movement by providing
points of attachment for muscles
Protects internal organs
Provides a framework for body tissues
Two types of bone tissue (compact bone
and spongy bone) that differ in density
