5th Science Q2

Heterotrophs Consume plants and other animals
Autotrophs Produce their own food
What does food provide for organisms? It provides the building blocks for growth, development and system repair (nutrients).
What level of consumer are humans? Humans are 4th level
Information that a food pyramid provides that a food web DOES NOT? Levels & whether its a composer, decomposer, producer and consumer.
Digestion Process of breaking down food into simple chemicals called nutrients.
How are human and painted lady butterfly digestive systems similar? They both have stomachs and intestines
Why is digestive system called a system? It has a ton of interacting parts.
What do your mouth and teeth do as their part of digestive system? Moisten and crush the food to prepare it.
What does your esophagus do as its part of the digestive system? Move the food from the mouth to the stomach.
What does your stomach do as its part of the digestive system? Adds gastric juices to the food.
What do the small and large intestine do as its part of the digestive system? They help release nutrients into the bloodstream that is delivered to every cell in the body.
What does the colon do as its part of the digestive system? Compacts and dehydrates food waste.
What do the kidneys do as their part of the digestive system? Filters cellular waste from the blood and turns it into urine stored in the bladder.
What do the rectum & anus do as their part of the digestive system? Move indigestible material and dead bacteria called feces into the rectum and eliminate through the anus.
How are nutrients transported in a plant? Nutrients are transported from the xylem and the phloem to the cells in the plant.
Leaf veins Pathways found in and on leaves made up of tiny tubes which water and sap flow.
Sap Water carrying different kinds of dissolved plant nutrients / provides food to plant cells that make their own food.
Plant tube types: Xylem and Phloem
Xylem Transport water & minerals from vascular plant roots throughout the entire plants cells.
Phloem Delivers sugar to all the cells and tiniest of roots.
3 Leaf Vein Patterns: Parallel, Pinmate, Palmate
Describe Leaf Pattern Parallel Numerous veins extending the length of the leaf that all are parallel to one another.
Describe Leaf Pattern Pinmate Feather shaped leaves with one main vein running the length of leaf and smaller veins branching off it.
Describe Leaf Pattern Palmate Shaped like the palm of a hand with several large veins starting from a central point and extending out in several directions and smaller branched out veins.
Leaf Classification (3) Venation patterns, Edges/Margins, Shape
Process of Transportation (leaves) Water is removed from cells and passed into the environment.
Outside Investigation (leaves) Plastic bags placed over leaves of outdoor plants and moisture is found several hours later. Moisture is evidence for process of transportation.
How does water get to the cells at the top of the plant? From the Xylem system
How does sugar get to the cells that can't make their own food? Sap through the Phloem system.
How do humans transport nutrients to all the cells? Through the bloodstream.
Tricuspid heart valve Blood flows INTO RIGHT ventricle into heart FROM body.
Pulmonary heart valve Blood flows FROM RIGHT ventricle as its pumped TO LUNGS.
Mitral heart valve Blood flows FROM LUNGS into LEFT ventricle.
Aortic heart valve Blood flows FROM LEFT ventricle and pumped OUT to body.
Human Circulatory System does: Pumps blood through vessels called arteries, veins and capillaries.
Arteries Blood vessels that carry blood FROM heart to the body.
Veins Blood vessels that carry blood TO heart from the body.
Capillaries Smallest blood vessels where gases, nutrients and waste are exchanged between capillaries and cells in order to survive.
Heart and role in the circulatory system 4 chamber pump made of muscles that pushes blood around in the circulatory system.
Right Ventricle function Pumps blood to the lungs. Blood flows from the lungs into the LEFT side of the heart.
Left Ventricle function Pumps blood to all the cells in the human body.
Heart valves function Act as one way doors making sure blood moves in only one direction.
Red blood cells function Carry oxygen to cells.
How do we breathe? We breathe to exchange gases, breathe in oxygen and release carbon dioxide.
Parts of the respiratory system: Lungs, system of lungs to the outside air and the diaphragm.
What is respiratory system function? Bring oxygen to the red blood cells and get rid of the waste carbon dioxide.
Alveoli Tiny air sacs at end of the bronchioles that receive the waste carbon dioxide from the body's cells.
Alveoli function To transfer carbon dioxide from the red blood cells into air within the sacs.
