Solutions (ch 1-5) Dr. Henry Structural Orangization - Correct Answer -Chemical -Cellular -Tissue -Organ -Organ system -Organism Requirements for Life - Correct Answer maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, growth maintaining boundaries - Correct Answer Separation between internal and external environments must exist Movement - Correct Answer Muscular system allows movement Contractility - Correct Answer refers to movement at the cellular level Responsiveness - Correct Answer ability to sense and respond to stimuli Digestion - Correct Answer Breakdown of ingested foodstuffs, followed by absorption of simple molecules into blood Metabolism - Correct Answer all chemical reactions that occur in body cells, sum of all catabolism & anabolism Excretion - Correct Answer removal of wastes from metabolism and digestion Reproduction - Correct Answer -cellular level, reproduction involves division of cells for growth or repair -organism level, reproduction is the production of offspring 1 / 3
Growth - Correct Answer increase in size of a body part of an organism Humans are ______ individuals, cells must be kept alive - Correct Answer multicellular Intergumentary system - Correct Answer Components: Skin, hair, nails, sweat and oil glands Functions: Protection, regulate body temperature, eliminates some waste, detect sensation skeletal system - Correct Answer Components: Bones and joints of the body and their associated cartilages Functions: Supports and protects, provides a surface area for muscle, aids body movement Muscular System - Correct Answer Components: Muscles composed of skeletal muscle tissue Functions: Produces body movements, such as walking, stabilizes body position, generates heat nervous system - Correct Answer Components: Brain, spinal cord, nerves, and special sense organs, such as the eyes and ears endocrine system - Correct Answer Components: glands, pancreas, ovaries, and hormone producing cells in several other organs cardiovascular system - Correct Answer Components: Blood, Heart, and blood vessels Functions:Heart pumps blood through body vessels, blood carries oxygen and nutrients to cells and carbon dioxide and wastes away from cells and helps regulate acid-base balance. temperature, ad water content of body fluids, blood components help defend against disease and repair damaged blood vessels.digestive system - Correct Answer Components: Organs of gastrointestinal tract, pharynx throat, esophagus, stomach, large and small intestines and anus, also includes accessory organs like liver and gall bladder urinary system - Correct Answer Components: Kidneys, ureters, urinary bladder, and urethra Function: Produces, stores, and eliminates urine, eliminates wastes and regulate volume and chemical composition of blood 2 / 3
lymphatic system - Correct Answer Components: Lymphatic fluid and vessels, including spleen, thymus, lymph nodes, and tonsils
Functions: returns proteins and fluid to blood
respiratory system - Correct Answer Components: Lungs and air passage ways such as the pharynx, trachea, bronchial tubes leading into out of the lungs Functions: transfers oxygen from inhaled air to blood and carbon dioxide from blood to exhaled air Reproductive system - Correct Answer Components: Gonads (testes and ovaries) and associated organs Survival Needs - Correct Answer nutrients, oxygen, water, normal body temperature, appropriate atmospheric pressure Catabolism - Correct Answer the breakdown of complex chemical substances into simpler components Anabolism - Correct Answer the building up of complex chemical substances from smaller, simpler components Polymer - Correct Answer A long molecule consisting of many similar or identical monomers linked together by anabolism Monomer - Correct Answer A simple compound whose molecules can join together to form polymers Homeostatic control of variables involves three components - Correct Answer Receptor, control center, and effector homeostasis - Correct Answer is the maintenance of relatively stable internal conditions despite continuous changes in environment a condition of equilibrium in the body's internal environment
