(25 cards)
Hypothesis
A supposition or proposed explanation made on the basis of limited or limited evidence as a starting point for further investigation.
Constant Variable
A constant variable is one whose value cannot be updated or altered anywhere in your program. A constant variable must be initialized at its declaration.
Excretory System
Excretory systems regulate the chemical composition of body fluids by removing metabolic wastes and retaining the proper amounts of water, salts, and nutrient. Components of this system in vertebrates include the kidneys, liver, lungs, and skin.
Circulatory System
The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The hear then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
Respiratory System
The respiratory system is the network of the organs and tissues that help you breathe. It includes your airways. Lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
Cell
The smallest unit of an organism that can carry out the basic functions of like.
Organ System
The 11 organ systems include the respiratory system, digestive and excretory system, circulatory system, urinary system, integumentary system, skeletal system, muscular system, endocrine system, lymphatic system, nervous system, and reproductive system.
Carbohydrates
One of the three basic food types. May be in the form of starch, sugar, or fiber. Found in cereals, breads, and vegetables.
Sugar
A sweet crystalline substance obtained from various plants, especially sugar cane and sugar beet, consisting essentially of sucrose, and used as a sweetener in food and drinks.
Independent Variable
A variable (often denoted by x) whose variation does not depend on that of another.
Digestive System
The digestive system includes the mouths, pharynx (throat), esophagus, stomach, small intestines, large intestines, rectum, and anus. It also includes the salivary glands, liver, gallbladder, and pancreas, which make digestive juices and enzymes that help the body digest food and liquids.
Endocrine System
The endocrine system, made up of all the body’s different hormones, regulates all biological process in the body from concept through adulthood and into old age, including the development of the brain and nervous system, the growth and function of the reproductive system, as well as the metabolism and blood sugar.
Integumentary System
The integumentary system is the largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain. The integumentary system includes the epidermis, dermis, hypodermics, associated glands, hair, and nails.
Reproductive System
The tissues, glands and organs involved in producing offspring.
Tissue
A group of similar cells that work together to carry out a specific function. The function of muscle tissue, for example, is to contract.
Accessory System
Accessory organs of digestion are organs that secrete substances needed for the chemical digestion of food, but through which food does not actually pass as it is digested. The accessory organs include the liver, gallbladder, and pancreas.
Benedict’s Solution
Benedict’s reagent, also known as Benedict’s solution, is a chemical reagent which is made up of a complex mixture of sodium citrate, sodium carbonate, and the pentahydrate of copper sulfate.
Starch
An odorless, tasteless white substance occurring widely in plant tissue and obtained chiefly from cereals and potatoes. It is a polysaccharide which functions as a carbohydrate store and is an important constituent of the human diet.
Dependent Variable
A variable (often denoted by y) whose value depends on that of another.
Muscular System
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
Lymphatic/Immune System
The lymphatic system is important for the optimal functioning of our general and specific immune responses. The lymph nodes monitor the lymph flowing into them and produce cells and antibodies which protect our body from infection and disease.
Nervous System
The nervous system has two main parts: the central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
Organ
A part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in humans.
Sphincter
A ring of muscle surrounding and serving to guard or close an opening or a tube, such as the anus or the openings of the stomach.
