2HomeostasisHomeostasis is the regulation of an organisms internal, life-maintaining conditions despite changes in the environment.
3SystemsSystems are groups of interacting components that perform a certain function.Examples: Organ System, Solar System, and working technological parts.
4Matter Matter is anything that takes up space and has mass. Examples: Solids, Liquids, and Gasses. And pretty much anything!!!
5Atoms Atoms are the smallest basic particles of matter. Examples are hydrogen atoms, oxygen atoms, and nitrogen atoms.
6Molecules Molecules consist of two or more atoms put together. Examples: Water (H20), Carbon Dioxide (CO2), and Methane (CH4).
7CellsCells are the smallest basic unit of life. Cells are the building blocks of life.Examples: Eukaryotic Cells and Prokaryotic Cells
8TissuesTissue is a group of cells working together to perform a specific function.Examples: Muscle Tissue, Nervous Tissue (brain, spinal cord)
9OrgansOrgan is two or more tissues working together to perform a specific function in the body.Examples: Heart, Lungs, Brain, Kidneys, Eye, Stomach, Skin, and Bones.
10Organ SystemsSystem: A group of interacting components that perform a certain function.Example to the left is the Skeletal SystemOther Examples: Circulatory System, Digestive System, Immune System, Nervous System, and Respiratory System.
11Organisms Organism is an individual living system or creature. An organism maybe unicellular or multi-cellularExamples: Crocodiles, Frogs, Plants, Bacteria, Humans, Lizards
12Which is the correct order from smallest to largest? A. Tissue, Cell, Organ, Organ System, OrganismB. Cell, Tissue, Organ System, Organ, OrganismC. Cell, Tissue, Organ, Organ System, OrganismD. Cell, Organ, Tissue, Organ System, Organism
13Types of TissuesEpithelial Tissue: Covers and protects the underlying tissue.Example of this is Skin
14Types of TissuesNervous Tissue sends electrical signals throughout the body.Examples of nervous tissue are your brain tissue and spinal cord tissue.
15Types of TissuesMuscle Tissue is made of cells that contract and relax to produce movement.Your Arms, Heart, and Stomach have muscle tissue
16Types of TissuesConnective Tissue helps join, supports, protect, insulate, nourish and cushion organs.
18OrgansOrgan is two or more tissues working together to perform a specific function in the body.Examples: Heart, Lungs, Brain, Kidneys, Eye, Stomach, Skin, and Bones.
19Organ SystemsSystem: A group of interacting components that perform a certain function.Example to the left is the Skeletal SystemOther Examples: Circulatory System, Digestive System, Immune System, Nervous System, and Respiratory System.
20Organ Systems Integumentary System protects tissues and cells beneath So what types of tissues does the integumentary system primarily composed of?
21Organ Systems Muscular System helps you move Made up primarily of muscle tissues.Muscles are found nearly every where throughout your body.Any place you can move or that naturally moves inside your body has muscle
22Organ Systems Skeletal System helps support and protect body parts Have you ever broken part of your skeletal system?How did it feel?Does it take the same amount of time to heal as another injury
23Organ SystemsCardiovascular System helps circulate blood throughout the body.Includes the heart, veins, and arteries.
24Organ SystemsRespiratory Systems helps absorb oxygen and release carbon dioxide.Perform the process of respiration!
25Organ SystemsUrinary System (Excretion System) filters or removes waste from your body.
26Organ SystemsMale Reproductive System produces sperm needed for reproduction.
27Organ SystemsFemale Reproductive System produces eggs needed for reproduction.
28Organ SystemsNervous System sends and receives electrical signals throughout the body.
29Organ SystemsDigestive System breaks down food into nutrients that the body can absorb.The cells absorb this nutrients by diffusion.
30Organ SystemsLymphatic System helps return leaked fluids to blood and gets rid of bacteria and viruses.
31Organ SystemsEndocrine System has glands that help send out chemical messages.Let’s you know when your hungry, tired, etc.
32Organisms Organism is an individual living system or creature. An organism maybe unicellular or multi-cellularExamples: Crocodiles, Frogs, Plants, Bacteria, Humans, Lizards
33What’s a System?A set of inter-related components working together to perform a specific function is a system.A function is a job of a person or an object.
34Question #11Which of the following statements describes how tissues, organs, and organ systems are related?A. Organs form tissues, which form organ systems.B. Organ Systems form organs, which form tissues.C. Tissues form organs, which form organ systems.D. None of the Above
35Question #12The human skeleton has 206 bones. The human skull has 22 bones. What percentage of human bones are skull bones?Skull Bones/Skeleton Bones=? Then take that answer and multiply it by 10022/206 X 100/1 = 10.68%
36Question #13 How is the human body and a car alike? Both the human body and a car contain several different systems. A car has an exhaust system to take in air and remove waste products. The human body has a respiratory system to take in air and a digestive system to get rid of waste products.
