  1. Circulatory System Rosalind Kuang, Farida Sidikova, Jerome Manigo, Vadim Aktur, and Ivonne Davalos Class-704

  2. What are the major organs of your system? • The major organs of the system are the heart, arteries, blood vessels and thecapillaries.

  3. What are their jobs? • The heart pumps the blood. The arteries carry blood away from the heart and the veins carry blood to the heart. The capillaries are small blood vessels that connects the arteries and the veins.

  4. What are the functions of your system? • Transport blood throughout the body. The veins carries the blood to the heart. The arteries carry the blood away.

  5. What does the system do? • The system provides a way for glucose, oxygen, and hormones to reach certain organs around the body.

  6. How does it do it? • The blood vessels carries blood to the lungs to be oxygenated and then back to the heart. In the lungs carbon dioxide is removed from the blood.

  7. Why is the circulatory system important to survival? • The circulatory system is important for survival because our system includes the blood. The blood keeps us alive. The circulatory system pumps oxygen throughout the body. The oxygen carries blood to the brain and other organs.

  8. Diseases and Disorders • Fatty deposits can block the coronary arteries and the blood cannot flow to the heart. Then the heart muscles start to die. When this happens a person suffers a heart attack. The brain needs oxygen pumped by the heart constantly otherwise you would get irreversible damage.

  9. Vocabulary • Arteries- blood vessels that carry blood away from the heart to every part of the body. • Blood Vessels-tubes that carry blood throughout the body. • Brain- the center of the nervous system in all vertebrate and invertebrate animals. • Capillaries-tiniest blood vessels in the body. • Coronary Artery- supplies oxygenated and nutrient filled blood to the heart muscle. • Fatty Deposits- made by fatty foods that blocks the blood vessels

  10. More Vocabulary • Glucose- A sugar having several optically different forms. • Heart -an organ that pumps blood. • Heart Attack- when coronary artery becomes blocked blood cannot flow to the heart, which causes a heart attack. • Heart Muscle- heart is a muscle located a little to the left of the middle of the chest. • Hormones- Chemicals that act as a catalysts for changes in cells.

  11. Even More Vocabulary • Irreversible Damage- Damage caused by various damage that is impossible to reverse. • Organs- a differentiated structure consisting of cells and tissues and performing same specific function in an organ. • Oxygen-gas in our air that we need to breathe in order to live; our body’s cells use it to make energy. • Pulmonary Circulation- flow of blood through the heart to the lungs and back to the heart. • Veins-Blood vessels that carry blood back to the heart from everywhere in the body.
