Topic: Circulatory System Aim: Explain the function and structure of the circulatory system. Do Now: Multiple Choice question (take out your numbers) HW: Respiratory System Reading notes due Monday Digestive and Circulatory Castle Learning due Wednesday
The main function of the digestive system is to 1.rid the body of cellular waste materials 2.process organic molecules so they can enter cells 3.break down glucose in order to release energy 4.change amino acids into proteins and carbohydrates
What is the primary function of the large intestine? 1.To digest proteins 2.To absorb nutrients 3.To break down complex carbohydrates 4.To remove water from undigested waste
Identify the blood vessel being described (A, V or C). 1.Largest and most muscular blood vessels. 2.The smallest blood vessels. 3.Capillaries carry blood to these blood vessels. 4.Blood vessel used to feel your pulse. 5.Carry blood to other organs. 6.Where the exchange of substances between the blood and cells occurs. 7.Most of these carry deoxygenated blood back to the heart. 8.Contain valves to prevent the backflow of blood. 9.Carry blood under high pressure. 10.Red blood cells travel move in single file.
Function TRANSPORT substances throughout the body
Where is oxygen transported? Where are wastes transported? What other substances are transported by the circulatory system?
Heart Facts Hold out your hand and make a fist. If you're a kid, your heart is about the same size as your fist, and if you're an adult, it's about the same size as two fists. Your heart beats about 100,000 times in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times.
Right atrium (DB) Right ventricle (DB) Pulmonary arteries (DB) Lungs (OB) Pulmonary Veins (OB) Left atrium (OB) Left ventricle (OB) Aorta (OB) Rest of the body Vena Cava (DB) Right atrium (DB)
Let’s summarize… 1.Explain the function of the circulatory system. 2.Describe the four chambers of the heart. 3.Explain the importance of heart valves. 4.Why is the septum so important? 5.Where is deoxygenated blood pumped to? 6.Where is oxygenated blood pumped to?
Review: Identify the part of the heart being described. 1.Chamber that receives oxygenated blood. 2.Wall that separates the right and left side of the heart. 3.Chamber that pumps out deoxygenated blood. 4.Chamber that receives deoxygenated blood. 5.Prevents the backflow of blood between atria and ventricles. 6.Chamber that pulps out oxygenated blood.
