Essential Question
PG 124
How do animal systems interact to
absorb nutrients?
Standard
B.10A - describe the interactions that occur among systems
that perform the functions of regulation, nutrient
absorption, reproduction, and defense from injury or illness
in animals
Presentations
What nutrients are needed
for your body to function?
•Food (carbohydrates, lipids,
proteins, vitamins, minerals)
•Water
•Oxygen
SYSTEMS INVOLVED
NUTRIENT
ABSORPTION

DRAW ALL OF THIS.
Circulatory
DIGESTIVE SYSTEM
• Main Parts:
• Mouth
• Esophagus
• Stomach
• Small intestine
• Large intestine
Getting & Using Food
• Ingest
• taking in food
• Digest
• mechanical digestion
• breaking up food into smaller pieces
• chemical digestion
intracellular
digestion
• breaking down food into molecules small enough to
be absorbed into cells using enzymes
• Absorb
• absorb nutrients across cell membranes
• diffusion
• active transport
• Eliminate
• undigested material passes out of body
extracellular
digestion

DIGESTIVE SYSTEM
• Main Functions:
• Mouth breaks down food into smaller pieces
• Stomach enzyme breaks food into biomolecules
(carbs, lipids, proteins)
• Small intestine breaks food into monomers and
absorbs nutrients
• Large intestine reabsorbs water
Lung Inflation!
How Lungs Work!
RESPIRATORY SYSTEM
• Main Parts:
• Nose
• Mouth
• Lungs
• Diaphragm
RESPIRATORY SYSTEM
• Main Functions:
• Nose & mouth filter air
as it comes in
• Diaphragm contracts and
relaxes to move the lungs
• Lungs expand and
contract for inhaling &
exhaling
• Oxygen diffuses into
blood
• Oxygen necessary to
release energy from food
(glucose)
Circulatory System
CIRCULATORY SYSTEM
• Main Parts:
• Blood vessels
• Heart
• Red blood cells
The Heart

Vein from Head and Body
Right Atrium

what’s in
digested food
red blood cells
white blood cells
oxygen
waste (urea)
platelets
carbon dioxide
plasma
hormones
Red Blood Cells
a biconcave disc
that is round and
flat without a
nucleus
contain
hemoglobin, a
molecule specially
designed to hold
oxygen and carry it
to cells that need it.
can change shape to an amazing extent,
without breaking, as it squeezes single
file through the capillaries.
CIRCULATORY SYSTEM
• Main Functions:
• Heart pumps blood through blood
vessels
• Transports oxygen & carbon dioxide to
and from the respiratory system
• Transports nutrients from the
digestive system to the rest of the
body
INTERACTION: Maintaining Homeostasis
• Balancing glucose levels in blood
depress

glucose
from blood
liver

DEBRIEF:
Explain how all three systems
work together for nutrient
absorption in the body.
