Biological Processes


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.
