Homeostasis
Back to Boy Slide
• ALL system work together to maintain the balance
• Homeostasis-Temperature: The skin will begin sweating to
cool down the body.
• Waste and water: The circulatory and Excretory system will
remove waste and excess water from the body, and the
kidneys will conserve water as necessary. The skin also
conserves water by covering the body.
• The ultimate control of homeostasis is accomplished by the
nervous system (for rapid responses such as reflexes to avoid
picking up a hot pot off the stove) and the endocrine system
(for longer-term responses, such as maintaining the body
levels of calcium, etc.)
Back to Girl slide
Excreting Wastes
Back to Boy Slide
• Excretory: The kidneys remove toxins and urea from
the blood as well as excess water and remove it from
the body as urine.
• Digestive: Removes solid undigested waste
• Respiratory: removes carbon dioxide waste and
other gas wastes from the blood
• Circulatory: carries the waste to the lungs and
kidneys.
• Integumentary: The skin can also remove toxins in
the sweat.

Moving and Running

• The nervous system sends signals to the
muscle to contract them, the muscles then
pull on the bones to move the part.
• Respiratory and Circulatory bring the oxygen
to the cells for cellular respiration and then
carry the carbon dioxide away.
Back to Girl slide
Sending Signals
Back to Boy slide
• Nervous: sends ‘electric’ signals to control
almost all bodily functions especially in
response to the environment.
• Endocrine systems sends chemical signals to
control the balance of nutrients and other
substances in the body
• Circulatory system carries the chemical signals
in the blood.
Back To Girl Slide
Exchange of Gases
Back to Boy
Slide
• Respiratory & Circulatory work together to
exchange both Oxygen and Carbon dioxide.
• When we inhale, the lungs bring oxygen into
the body which diffuses into the blood.
• The blood carries the oxygen around the body
where it can diffuse into the cells and it picks
up the carbon dioxide that diffused out of the
cells and carries it back to the lungs where it is
exhaled out.

Slide
Food/Nutrients to cells
Back to Boy
slide
• Food/nutrients are brought into the body
through the digestive system where it is
broken down into very small molecules
• The Circulatory system carries these nutrient
molecules around the body to the cells
• Endocrine: produces substances, like insulin,
which aid in the absorption of the nutrients
into the cells.

Make Offspring
Back to Boy Slide
• Reproductive system has specialized organs to
make gametes (sex cells) and to nurture the
growing fetus until birth.
• Endocrine system: releases hormones which
cause the reproductive organs to develop at
puberty and sends chemicals signals to control
these organs to making and releasing sex cells.
Back to Girl Slide
Fighting pathogens
Back to Boy Slide
• Immune system produces cells which
recognize diseased cells or pathogens and
destroy them.
• Circulatory system carries these immune cells
around the body to fight disease.
• The lymphatic system stores the immune cells
in lymph nodes.
Back to Girl Slide
Barriers to Pathogens
Back to Boy slide
• The integumentary (skin) is the first line of defense,
by covering the body and keeping pathogens out of
the body.
• The digestive system acts to keep food borne
pathogens out of the body by destroying them
through enzymes or acids, or through competition
with the good bacteria in our intestines
• The immune cells are the last line of defense in killing
pathogens when they get in.
