Nutrient Procurement & Processing Flashcards
Nutrients help living organisms develop their bodies, grow, heal damaged body parts, and give energy for life and activity
Nutrition
Can produce their own food
Autotrophic
Cannot produce their own food
Heterotrophic
The mechanical and chemical process by which complex food substances are broken down into simpler substances
Digestion
Parts of the Digestive System
Produces saliva where
mechanical mastication of
food takes place to form
bolus
Mouth
Parts of the Digestive System
A muscular tube that
conducts peristalsis and
served as passageway for
food
Esophagus
Parts of the Digestive System
A muscular sac that contains
gastric juices that helps to
break down the food
chemically
Stomach
Parts of the Digestive System
Produces bile that helps in the
digestion of fats
Liver
Parts of the Digestive System
Helps in the storage of bile
and discharging it from the
cystic duct
Gall Bladder
Parts of the Digestive System
Release pancreatic juices and
enzymes which help in the
digestion of protein and
starch
Pancreas
Parts of the Digestive System
A tube that absorbs water and
salts from the material that has
not been digested as food, and
gets rid of any waste product
Large Intestine
Parts of the Digestive System
A tube that contains villi
which absorbs the nutrients
and water coming from food
Small Intestine
Digestive Process
_____ - taking in food materials
Ingestion
Digestive Process
_____ - breaking down food molecules into smaller pieces
Digestion
Parts of the Digestive System
- Temporary storage of feces
- An opening that eliminates
feces in the body
Rectum and Anus
Digestive Process
_____ - movement of nutrients, water and electrolytes from small intestine to the cell, then into the blood
Absorption
Digestive Process
_____ - undigested material passes out of the system
Elimination
Enumerate the Digestive Process
Ingestion, Digestion, Absorption, Elimination
Feeding Mechanisms (Animals)
- Animals that live on the
source of their food and eat
through it. - Earthworm, caterpillars,
and termites
Substrate-feeders
Formula of photosynthesis
6CO2 + 6H2O + Sunlight –>
C6H12O6 + 6O2
Feeding Mechanisms (Animals)
- Animals suck fluid
containing nutrients from
another animals - Aphids, leeches, and
mosquitoes
Fluid-feeders
Feeding Mechanisms (Animals)
- Aquatic animals strain the
food particles from the
water - Clams, Whale shark, Hydra
Filter-feeders
Feeding Mechanisms (Animals)
- Animals break-down and
swallow large amount of
food particles - Lion, wolves, cats
Bulk-feeders
Plant Nutrition
It absorbs and transports
water and nutrients from
the soil to the rest of plant.
Roots
