The Circulatory System Structure, Function, and Information Processing Unit: MS.LS 1-3 ~ Use argument supported by evidence for how the body is a system of interacting subsystems composed of group of cells. Greek word: CARDIO means heart VASCULAR means vessel Location of Heart I. Function of Circulatory or Cardiovascular System A. Circulatory System – Keeps the body working by delivering oxygen to body cells and removing waste (CO2) from the cells. Delivering Removing Questions 1. What is the main job of the Cardiovascular System? Questions 1. What are the one main job of the Cardiovascular System? a. Transport nutrients and oxygen ll. Sub-systems and the components that work together to support this system: A. Blood – connective tissue made of cells, cell parts and plasma. Blood is made up of about 45% solids (cells) and 55% fluids (plasma). i. Parts of the Blood 1. Red Blood Cells – Made in bone marrow; carries oxygen, food, and rids body of CO2 and waste 2. White Blood Cells – Help fight disease and infection by destroying bacteria and germs that enter the body. Made in the lymph nodes Parts of the Blood 3. Platelets – Help blood to clot, to prevent excess bleeding. 4. Plasma – Water portion of the blood; 55% of blood is plasma ii. Four Types of Blood • • • • • Type A: 42% Accepts A and O Type B: 10% Accepts B and O Type AB: 3% Accepts AB and O Type O: 45% Universal Donor RH Factor = is the + and – of the blood Questions 1. What is blood? 2. What are the four parts of the blood AND tell what each part does. a. b. c. d. Questions 1. What is blood? connective tissue made of cells, cell parts and plasma. Blood is made up of about 45% solids (cells) and 55% fluids (plasma). 2. What are the four parts of the blood AND tell what each part does. a. Red blood cells – carry oxygen b. White blood cells – fight disease c. Platelets – help blood clot d. plasma- liquid part of blood Parts of the Circulatory System B. The Heart - is divided into FOUR Chambers 1. Two Types of Arteries • Arteries start with A takes blood away !! • Aorta – Largest blood vessel in the heart • Pulmonary Artery – Carries blood containing carbon dioxide from your heart to your lungs • Pulse - each time the heart beats, blood is pumped out of the heart with pressure. 2.Three Types of Veins • Veins start with V brings blood back to me – 1. Inferior Vena Cava – Where the blood enters the heart from the body. – 2. Superior Vena Cava – Where the blood enters the heart from the body. – 3. Pulmonary Vein – Carries blood-containing oxygen from your lungs to your heart. 3. Capillaries a. Connect arteries and veins b. Smallest blood vessels in our body c. Blood cells pass through capillaries in single file d. Allows nutrients, oxygen and other substances through the capillary walls. 4. Blood Pressure – the force exerted by the blood on the walls of a blood vessel. The Four Valves of the Heart • Tricuspid Valve – Lets the blood fill in the right atrium before it enters the right ventricle. • Bicuspid Valve – Lets the blood fill in the left atrium before it enters the left ventricle The Four Valves of the Heart • Right Semi lunar ValveLets the right ventricle fill before releasing the blood into the pulmonary artery. • Left Semi lunar Valve – Lets the blood fill in the left ventricle before sending it to the aorta • Septum – Divides the heart in half The American Heart Association reports that a normal heart will beat 100,000 times a day. About 2,000 pints of blood is pumped through the body on each day. The average human heart will beat about 2 billion times throughout the life of a 70year-old person. 2. Viens 1. Arteries Three Kinds of Blood Vessels • Arteries – Carries blood away from the heart • Veins – Carries blood back to the heart • Capillaries – Delivers low-oxygen blood to veins (Smallest) Questions
