  1. The CirculatorySystem

  2. Warm Up: Compare and Contrast the following systems in complete sentences ~ Excretory System ~ Urinary System

  3. Function Transportation system by which oxygen and nutrients reach the body's cells, and waste materials are carried away. Also carries substances called hormones, which control body processes, and antibodies to fight invading germs.

  4. Circulatory System Works with…. • Digestive System ~ breaks down food and nutrients • Respiratory System • ~ provides oxygen that cells need to release energy • Transports materials from the digestive system and the respiratory system to the cells

  5. Parts of the Circulatory System • Divided into three major parts: • The Heart • The Blood • The Blood Vessels

  6. The heart, the lungs, and the bloo dvessels work together toform the the circulatory system.

  8. 3 Types of Circulation: Pulmonary circulation Coronary circulation Systemic circulation

  9. Pulmonary Circulation Movement of blood from the heart, to the lungs, and back to the heart again

  11. Coronary Circulation Movement of blood through the tissues of the heart

  13. Systemic Circulation Supplies nourishment to all of the tissue located throughout the body , except for the heart and lungs

  14. http://sln.fi.edu/biosci/systems/systemic.html

  15. Blood Vessels Hollow tubes that circulate your blood

  16. Three Types of Blood Vessels Arteries Veins Capillaries

  17. Arteries Carry blood AWAY from the heart Heart pumps blood Main artery called the aorta Aorta divides and branches Each region of your body has system of arteries supplying it with fresh, oxygen-rich blood.

  18. Arteries • Tough on the outside • Smooth on the inside • Muscular wall helps the heart pump blood

  19. Have strong, muscular walls The inner layer is very smooth so that the blood can flow easily http://hes.ucf.k12.pa.us/gclaypo/circdia.html

  20. http://sln.fi.edu/biosci/systems/circulation.html

  21. Capillaries • Very thin • Only one cell thick • Connect arteries & veins

  22. Capillaries Food and oxygen released to the body cells Carbon dioxide and other waste products returned to the bloodstream

  25. Valves are located inside the veins. The valves only allow blood to move in one direction. http://hes.ucf.k12.pa.us/gclaypo/circdia.html

  26. Veins Carry blood to the heart Receive blood from the capillaries Transport waste-rich/ oxygen-poor blood back to the lungs and heart Valves are located inside the veins Allow blood to move in one direction

  28. Close up of heart valveHeart sounds are made by the valvesas they open and close http://hes.ucf.k12.pa.us/gclaypo/circdia.html

  29. Blood Pumped by your heart. Travels through thousands of miles of blood vessels Carries nutrients, water, oxygen and waste products to and from your body cells. Made up of liquids, solids and small amounts of oxygen and carbon dioxide.

  30. Red Blood Cells • Red blood cells carry oxygen from the lungs to all the cells of the body. • Takes carbon dioxide and transports it back to the lungs • About 5,000,000 Red Blood Cells in ONE drop of blood. • Made in red bone marrow • Circulate for 120 days

  31. http://hes.ucf.k12.pa.us/gclaypo/circdia.html

  32. White Blood Cells • White blood cells protect the body from germs • Guard against infection, fight parasites, and attack bacteria • Number of WBC’s increases when body is fighting

  34. Platelets • Platelets are blood cells that help stop bleeding • Forms a net-like structure for clotting

  35. user.gru.net/clawrence/ vccl/chpt7/plate.htm

  36. Plasma • Plasma is the liquid part of the blood • About half of your blood is made of plasma • The plasma carries the blood cells throughout the body • 10% dissolved gases, salts, nutrients, enzymes, hormones, wastes, and proteins. • 90% water • Plasma is made in the liver.

  38. What is the Scenario? • A person cannot get out of the bed early in the morning. The person is feeling very tired throughout the day, which causes their work habit to be low.
