The circulatory system is a really important part of our body. The word ‘circulatory’ means something that is going : Round and round in a circle or loop. This is exactly what is happening in our bodies Title: The Circulatory System What is the circulatory system? The circulatory system is made up of : 1.The Heart 2.all the blood vessels in the body (3 types) Its function: It carries oxygen, nutrients, and hormones to cells, and removes waste  Title: The Circulatory System What circulates and why? The blood is doing a really important job – it is taking nutrients, hormones and oxygen all around the body to all the places they need to go. The oxygen comes into your body when we breathe in and it goes into our lungs. Then, inside the lungs, this oxygen goes into our blood and starts its journey around the body. You could think of the blood cells a bit like delivery drivers that drop off substances to where it needs to be. Oxygen is dropped off all around the body to thinner blood vessels, which move the Title: Quick Fire Quiz 1. Blood cells are a bit like… A. Delivery drivers B. Guards C. Cooks D.

The first goes to and from the heart visiting the lungs to collect oxygen and get rid of carbon dioxide. 2. The other loop is much larger and goes from and to the heart, but travels all around the body in between. This is often called a 'figure of eight system'. Title: True or False 1. Humans have a 3. Blood first travels to DOUB single LE circulatory the lungs then back to system the heart 2. The function of the circulatory system Is to carry oxygen, nutrients, and hormones to cells, and remove waste products Learning Objectives: Explain what is meant by the circulatory system ​ Label a diagram of the heart To Describe the three types of blood vessel, and the blood vessels in the heart Title: The Heart 1. The Heart The heart is at the heart of it all! Without the heart, no blood would get anywhere around your body. The heart is basically a big pump (made of muscle tissue) that constantly pumps the blood around the circulatory system. This has to happen all the time (even when you Title: The Heart 1. The Heart The heart is a large muscular organ which pumps blood to the lungs and then the rest of your body. It has four chambers: Top Chambers (collect blood): 2. right atrium 3. left atrium Bottom chambers (pump out NOTE: blood) : -Left and right are reversed because it is looking at your own heart from the outside 3. right ventricle -Pulmonary means it is associated with the lungs 4. left ventricle Title: Parts of the Heart 1. The Heart Chamber Function 1) Right Atrium Receives deoxygenated blood from the body. Pumps deoxygenated 3) Right Ventricle​ blood to the lungs. 2) Left atrium Receives oxygenated blood from the lungs. Pumps oxygenated 4) Left Ventricle​ blood around the body. Title: The Heart 1. The Heart The Atria collect blood and then pump them to the ventricles below. The Ventricles then pump the blood to the body. It looks as though the ventricles are bigger but the four chambers Did You Know...? The average persons' heart will beat 2.5 billion times during a lifetime. inside are the same size. It is the Amazingly, it takes under 20 seconds for one red blood cell to go round the whole body. muscular lining of the Red blood cells last about 4 months before your body makes new ones. ventricles that are bigger because they have to pump the Title: Quick fire quiz Why do the ventricles have thicker walls than the atria? A. The ventricles are smaller B. They have to pump the blood further than the atria. C. It is just how the heart is made Learning Objectives: Explain what is meant by the circulatory system ​ Label a diagram of the heart To Describe the three types of blood vessel, and the blood vessels in the heart Title: Blood Vessels We normally use the word vessel for a tube/container, so… Blood vessels are tubes that carry blood throughout the body and are part of the circulatory system. What E.G: objects can you think of, that are like toothpaste tube ‘vessels’? food container drinking straw hose  Title: Blood Vessels 2. There are three types of Blood Vessel:  Title: Blood Vessels 2. There are three types of Blood 1. ArteriesVessel: carry blood away from the heart straight after it has been pumped. This means it is under high pressure, so the walls of arteries are made of thick muscle to withstand this pressure. This muscle is also elastic to allow a pulse of blood to travel along when your heart beats. Arteries in the heart: 1. Pulmonary artery = takes deoxygenated blood to lungs  Title: Blood Vessels 2. There are three types of Blood 2. Veins Vessel: carry blood back to the heart. This blood is under lower pressure because some of it has been lost as it travelled around your body. The walls of veins are made of thinner muscle and are less elastic than arteries. Because the blood is under lower pressure, one-way valves in your veins stop it flowing backwards. Veins in the heart= 1. Pulmonary vein (lungs) takes oxygenated blood from lungs to heart  Title: Blood Vessels 2. There are three types of Blood Vessel: 3. Capillaries are the tiny blood vessels that branch out into every tissue in your body carrying substances your cells need like oxygen and glucose for respiration, and for removing waste products like carbon dioxide. They have very thin walls to allow these substances to move by diffusion in and out of Pulmonary means it is associated with the lungs Title: Blood Vessels Summary Table of blood vessels Blood Vessel Function and appearance 1.Arteries - Carry blood away from heart - High pressure - Thick elastic muscle 1.Veins - Carry blood to the heart - Lower pressure - Thinner and less elastic - Contains valves 1.Capillaries - Branch out to every tissue - Connect arteries and veins - Very thin walls (one cell thick!)  Title: Blood Vessels The three types of Blood Vessel: Let’s practice! 1. Arteries = AWAY (from the heart) 2. Veins = RETURN (back to the heart) 3. Capillaries = CONNECTION (to tissues in body and other 2 blood vessels) NOTE: usually arteries carry oxygenated blood and veins carry deoxygenated blood, however the ONLY exception is the pulmonary artery and vein in the heart- it’s the opposite! Title: Complete the sentences activity Fill in the missing sentences with the words at the bottom : 1.
