Cigarettes contain nicotine, which is a stimulant, and is addictive. They can cause damage to the lungs and heart. The circulatory system is centred on the heart, an organ that works constantly to pump blood around the body.\u003Cbr>The heart is made up of four sections, called chambers.There are two sides to the heart (right and left) each of which have an atrium (at the top) and a ventricle (at the bottom). The left atrium receives blood from the lungs and the right atrium receives it from the rest of the body.\u003Cbr>The left ventricle pushes blood to the lungs and the right atrium pushes blood to the rest of the body.\u003Cbr>Circulatory system A system which includes the heart, veins, arteries and blood transporting substances around the body. Blood vessels The tube-like structures that carry blood through the tissues and organs. Veins Carry deoxygenated blood toward the heart. Arteries Carry oxygenated blood away from the heart. \u003Cbr>Parts of Blood Plasma The only liquid part of blood. It carries nutrients round the body. Platelets The help to stop bleeding when the body is cut. Red blood\u003Cbr>cells These carry oxygen around the body. White blood\u003Cbr>cells These fight infection when the body is sick. Capillaries The smallest blood vessels in the body and it is here that the exchange of water, nutrients, oxygen and carbon dioxide takes place. Circulate To move continuously through a system. Drug A substance containing natural or man-made chemicals that has an effect on your body when it enters your system. Alcohol A drug produced from grains, fruits or vegetables when they are put through a process called fermentation. Stimulant Increases activity of the central nervous system and body. Depressant Can help relax muscles and nerves. MAKING LINKS TO PREVIOUS LEARNING\u003Cbr>GOLDEN VOCABULARY Regular exercise • strengthens muscles including the heart muscle;\u003Cbr>• improves circulation;\u003Cbr>• increases the amount of oxygen around the body;\u003Cbr>• releases brain chemicals which help you feel calm and relaxed;\u003Cbr>• helps you sleep more easily;\u003Cbr>• strengthens bones.\u003Cbr>It can even help to stop us from getting ill. Digestive System The human body digests food to absorb the nutrients. digest To break down food into substances that can be absorbed by the body Life Cycle Living things reproduce in different ways. reproduce To produce offspring through sexual or asexual reproduction. Animals including humans The heart pumps blood around human bodies. blood The red liquid that circulates in the arteries and veins of vertebrate animals. Animals including humans The heart is a vital organ that keeps humans alive by pumping blood. heart An organ that pumps blood around the circulatory system\u003Cbr>|\n|  |\n\n© Vocabulary Ninja Ltd 2021","cbCaiiGToHQf4I4B","https://ap.wps.com/l/cbCaiiGToHQf4I4B","pdf",640260,"English","# Essential Human Body Vocabulary\n## Drugs\n## Circulatory system and the heart\n## Blood vessels and blood components\n## Golden Vocabulary and links to previous learning","[{\"question\":\"What is a drug, and how can it affect health?\",\"answer\":\"A drug is a chemical substance that has an effect on the body.
