Question | Answer |
---|---|
What is the order of the levels of organization? | Atom -> Molecule -> Cell -> Tissue -> Organ -> Organ System -> Organism -> Population -> Community -> Ecosystem -> Biome -> Biosphere |
What are biomolecules? | Large, organic molecules that make up living. |
What are the biomolecules? | Carbohydrates, Lipids, Proteins, and Nucleic Acids |
What is nervous tissue? | Tissue that reacts to stimuli and transmits signals throughout the body. |
What is muscular tissue? | Tissue that is specialized to contract and allow for voluntary movement of the body and its parts. |
What is epithelial tissue? | Tissue that lines the surface of the organs and the body cavities. |
What is connective tissue? | Tissue that is specialized to connect and support other tissues. It is the most widespread tissue in the body and can range from bones, to blood, to fat tissue. |
What combines together to make different tissues? | Cells |
What combines together to make different organs? | Tissues |
Are organs made of different tissues? | Yes, and organ can be made of different types of tissues, like the eye, which is made of all 4. |
What are all the organ systems? | Nervous, Integumentary, Immune/Lymphatic, Muscular, Circulatory, Skeletal, Respiratory, Digestive, Excretory, Endocrine, and Reproductive. |
What is the nervous system made of? | Brain, Spinal Cord, and Nerves. |
What does the nervous system do? | It recognizes and coordinates the body's response to changes in the internal and external environments. |
What is the integumentary system made of? | Skin, Hair, Nails, Sweat, and Oil Glands. |
What does the integumentary system do? | Guards against infection and ultra-violet radiation from the sun; helps to regulate body temperature. |
What is the immune/lymphatic system made of? | White Blood Cells, Thymus, Spleen, Lymph Nodes, and Lymph Vessels. |
What does the immune/lymphatic system do? | Helps protect the body from disease; collects fluid lost from blood vessels and returns it to the circulatory system. |
What is the muscular system made of? | Skeletal Muscle, Smooth Muscle, and Cardiac Muscle. |
What does the muscular system do? | Works with the skeletal system to produce voluntary movement; helps to circulate blood and move food through the digestive system. |
What is the circulatory system made of? | Heart, Blood Vessels, Blood. |
What does the circulatory system do? | Transport oxygen, nutrients, and hormones to cells; fights infection; removes cell waste; helps to regulate body temperature. |
What is the skeletal system made of? | Bones, Cartilage, Ligaments, and Tendons. |
What does the skeletal system do? | Supports the body; protects internal organs; allows movement; stores mineral reserves; contains cells that produce blood cells. |
What is the respiratory system made of? | Nose, Mouth, Pharynx, Larynx, Trachea, Bronchi, Bronchioles, and Lungs. |
What does the respiratory system do? | Brings in oxygen needed for cellular respiration and removes excess carbon dioxide from the body. |
What is the digestive system made of? | Mouth, Pharynx, Esophagus, Stomach, Small Intestine, Large Intestine, and rectum |
What does the digestive system do? | Breaks down food; absorbs nutrients; eliminates wastes. |
What is the excretory system made of? | Skin, Lungs, Liver, Kidneys, Ureters, Urinary Bladder, and Urethra. |
What does the excretory system do? | Eliminates waste products from the body. |
What is the endocrine system made of? | Hypothalamus, Pituitary, Thyroid, Parathyroids, Adrenals, Pancreas, and Ovaries(in females) or Testes(in males). |
What does the endocrine system do? | Controls growth, development, and metabolism; maintains homeostasis. |
What is the reproductive system made of? | In males: Testes, Epididymis, Vas Deferns, Urethra, and Male genitalia. In females: Ovaries, Fallopian Tubes, Uterus, and Female Genitalia. |
What combines together to make different organ systems? | Organs |
Can an organ be in more than one organ system? | Yes, for example, they lungs are in both the repository and the excretory systems. |
What is a population? | A group of individuals that belong to the same species and live in the same area. |
What is a community? | An assemblage of different populations that live in a defined area. |
What is an ecosystem? | All the organisms that live in a place, together with the abiotic factors. |
What is a biome? | A group of ecosystems that share similar climates and typical organisms. |
What is the biosphere? | Our entire planet, with all its organisms and abiotic factors. |
What are abiotic factors? | Non-living things. |
What are biotic factors | Living things. |
