| Question | Answer |
|---|---|
| an alternate form that a gene may have for a single trait | alleles |
| building block of protein | amino acids |
| blood vessel that carries blood away from the heart | arteries |
| consists of a bone with a rounded end that fits into a cuplike cavity on another bone; shoulder and hip | ball and socket |
| elastic, muscular organ that holds urine until it leaves the body through the urethra | bladder |
| microscopic blood vessels that connect arteries and veins; diffuse waste and nutrients out and into cells | capillaries |
| nutrient that usually is the body's main source of energy | carbohydrates |
| heart muscles | cardiac muscles |
| cartilage = thick, smooth, flexible, and slippery tissue layer that covers the ends of bones, make movement easier by reducing friction, absorbs shocks | |
| cellular respiration = oxygen delivered to the cells is used to release energy from glucose | |
| chemical digestion = occurs when enzymes and other chemicals break down large food molecules into smaller ones | |
| compact bone = strong layer of bone directly under the periosteum | |
| coronary circulation = flow of blood to and from the tissues of the heart | |
| essential amino acids = eight amino acids that cannot be made in your body's cells. they have to be supplied by the foods you eat | |
| fats = nutrient that stores energy, cushions organs, and helps the body absorb vitamins | |
| genetics = section of DNA on a chromosome that contains instruction making specific proteins | |
| genotype = the genetic make-up of an organism | |
| gliding joints one part of a bone slides over another bone---back and forth motion; wrist, ankles, and between vertebrae | |
| heredity = the passing of traits from parent to offspring | |
| heterozygous = describes an organism with two different allels for a trait | |
| hinge joint = back and forth movement; elbows knees, and fingers | |
| homozygous = describes an organism with two alleles that are the same for a trait | |
| immovable joint =joints that do not move, skull | |
| involuntary = you cannot control, it happens automatically like your heart beating. | |
| kidneys = bean shaped urinary system organ that is made up of about one million nephrons and filters blood, producing urine | |
| marrow =located in the cavities of spongy bone; yellow is made of fat and red produces red blood cells | |
| mechanical digestion = breakdown of food through chewing, mixing, and churning | |
| melanin pigment = produced by the epidermis that protects skin from sun damage and gives skin and eyes their color | |
| minerals = inorganic nutrient that regulates many chemical reactions in the body | |
| nephrons = tiny filtering unit of the kidney | |
| nutrients = substances in foods that provide energy and materials for cell development, growth, and repair | |
| periosteum = tough tight fitting membrane that covers a bone's surface and contains blood vessels that transport nutrients into the bone | |
| peristalsis = waves of muscular contractions that move food through the digestive tract | |
| phenotype = outward physical appearance and behavior of an organism as a result of its genotype | |
| pivet joint = rotates; arm and leg | |
| plasma = liquid part of blood, made mostly of water , in which oxygen, nutrients, and mineral are dissolved | |
| platelets = irregular shaped cell fragment that helps clot blood and releases chemicals, thqat help form fibrin | |
| probability = possible outcomes | |
| proteins = large molecule that contains carbon, hydrogen, nitrogen, and sometimes sulfur and is made up of amino acids; used for growth, and replacement and repair of cells | |
| pulmonary circulation = flow of blood through the heart to the lungs and back to the heart | |
| skeletal muscles = move bones | |
| systemic circulation = largest part of the circulatory system, in which oxygen-rich blood flows to all the organs and body tissues, except the heart and lungs, and oxygen-poor blood is returned to the heart | |
| ureters = tube that carries urine from each kidney to the bladder | |
| urethra = tube that carries urine from the bladder to the outside of the body | |
| veins = blood vessel that carries blood to the heart | |
| vitamins = water-soluble or fat-soluble organic nutrient needed in small quantities for growth, for preventing some diseases, and regulating body functions. | |
| voluntary = can be moved by consciously control...you can make it move |
