Unit 4 – Animal Systems This unit will focus on human systems This unit will focus on human systems In unicellular (single-celled) organisms, the single cell performs all life functions - it functions independently. In unicellular (single-celled) organisms, the single cell performs all life functions - it functions independently. However, multicellular (many celled) organisms have various levels of organization within them. Individual cells may perform specific functions and also work together for the good of the entire organism. The cells become dependent on one another. However, multicellular (many celled) organisms have various levels of organization within them. Individual cells may perform specific functions and also work together for the good of the entire organism. The cells become dependent on one another. Multicellular organisms have the following 5 levels of organization ranging from simplest to most complex: Multicellular organisms have the following 5 levels of organization ranging from simplest to most complex: levels of organization: levels of organization: cells → tissues → organs → organ systems → organism cells → tissues → organs → organ systems → organism
Level 1 - Cells Are the basic unit of structure and function in living things. Are the basic unit of structure and function in living things. May serve a specific function within the organism May serve a specific function within the organism Examples- blood cells, nerve cells, bone cells, etc. Examples- blood cells, nerve cells, bone cells, etc.
Level 2 - Tissues Made up of cells that are similar in structure and function and which work together to perform a specific activity Made up of cells that are similar in structure and function and which work together to perform a specific activity Examples - blood, nervous, bone, etc. Examples - blood, nervous, bone, etc. Humans have 4 basic tissues: connective, epithelial, muscle, and nerve. Humans have 4 basic tissues: connective, epithelial, muscle, and nerve.
Level 3 - Organs Made up of tissues that work together to perform a specific activity Made up of tissues that work together to perform a specific activity Examples - heart, brain, skin, etc. Examples - heart, brain, skin, etc.
Level 4 – Organ Systems Groups of two or more organs that work together to perform a specific function for the organism. Groups of two or more organs that work together to perform a specific function for the organism. Examples - circulatory system, nervous system, skeletal system, etc. Examples - circulatory system, nervous system, skeletal system, etc. The Human body has 11 organ systems - circulatory, digestive, endocrine, excretory (urinary), immune (lymphatic), integumentary, muscular, nervous, reproductive, respiratory, and skeletal. The Human body has 11 organ systems - circulatory, digestive, endocrine, excretory (urinary), immune (lymphatic), integumentary, muscular, nervous, reproductive, respiratory, and skeletal.
Level 5 - Organism Entire living things that can carry out all basic life processes. Meaning they can take in materials, release energy from food, release wastes, grow, respond to the environment, and reproduce. Entire living things that can carry out all basic life processes. Meaning they can take in materials, release energy from food, release wastes, grow, respond to the environment, and reproduce. Usually made up of organ systems, but an organism may be made up of only one cell such as bacteria or protist. Usually made up of organ systems, but an organism may be made up of only one cell such as bacteria or protist. Examples - bacteria, amoeba, mushroom, sunflower, human Examples - bacteria, amoeba, mushroom, sunflower, human

8 Human Body Systems 1. Immune System 2. Nervous System 3. Excretory (Urinary) System 4. Respiratory System 5. Circulatory System 6. Digestive System 7. Muscular System 8. Skeletal System - 3 not covered – Integumentary, Endocrine, Reproductive
Items to remember: question quiz (3-5 vocab terms, short answer question, 10 multiple choice) 2. Keep it basic, try not to “cut and paste”! 3. Copernicus theme 4. Map of your system required 5. 5 minutes minimum, 15 minutes maximum in length 6. Practice pronunciation of terminology 7. All group members should participate in preparation & presentation 8. Follow the evaluation rubric Journey Through the Human Body Systems
