Transcript
Structures, Functions, and Interactions
Structures: Mouth, esophagus, liver, stomach,
gallbladder, pancreas, large intestines, small
intestines, rectum
Function: breaks down food into molecules the
body can use, and eliminates waste
Interactions: Uses the circulatory system to take
food to the individual cells, forms the end of the
excretory system to expel solid waste.
Structures: Heart, blood vessels
Functions: Heart pumps blood through all
blood vessels.
Interactions: Highway system of the body,
carries food (digestive) and oxygen
(respiratory) to the cells and carries waste
away.
Structures: brain, spinal column,
nerves.
Functions: detects & interprets info from
inside and outside the body; control
center
Interactions: Tells muscles to contract
(voluntary), tells heart to pump
(involuntary)
Structures: kidney, urinary bladder,
urethra, anus, large intestines
Functions: Blood is filtered through the
kidneys and removed from the body.
(Urinary) Unused digested foods are
removed through the anus (Excretory)
Interactions: Cleans waste from the
circulatory system and digestive system
Structures: Nose, Lungs, Wind Pipe
Function: Moves oxygen into the body
and removes carbon dioxide and water
from the body.
Interactions: Circulatory system carries
oxygen to the cells and carbon dioxide
away.
Structures: bones, cartilage, joints, marrow
Functions: provides shape and support,
enables you to move, protects your
internal organs
Interactions: bones make your red blood
cells (cardiovascular).
Structures: skeletal muscle, smooth muscle,
and cardiac muscle
Functions: Involuntary muscles are
responsible for activities such as
breathing and digesting food; Voluntary
muscles are under your control
Interactions: All systems, all of your organs
are made of muscle
Organs: glands, hypothalamus, thyroid,
ovaries, testes
Functions: Sends out chemical messages
Interactions: Sends growth hormones to
skeletal system.
Structures: white blood cells, skin, stomach,
phagocytes, lymphocytes
Function: defends the body against germs
and microorganisms
Interactions: All systems, Lymphatic system
gets rid of bacteria and viruses
