Cell Nucleus Vacuole Cell wall Objective: Achievers on the ROAD to college learn more extensively about the respiratory and circulatory systems and the tissues that make them The BIG ideas 1. Structure determines function. 2. Cells are the building blocks of life. 3. Our health and survival depend on the interactions of our cells. Let’s start our notes. Please take out a sheet of lined paper and write. Your Name Mr. Vo August 28, 2012 Respiratory and Circulatory Sytem We have 5 KP’s today. • KP1: The function of the respiratory system is to breath in oxygen and get rid of carbon dioxide – In normal breathing, we easily breathe in oxygen and breathe out carbon dioxide. – This process is known as gas exchange which occurs in the lungs • KP2: The lungs and trachea are the major organs in the respiratory system • KP3: Oxygen pathway: Oxygen enters from the nasal/mouth cavity pharynx larynx trachea bronchi alveoli • KP4: The functions of the circulatory system is to: 1. 2. 3. transport materials to and from cells such as oxygen, nutrients and wastes Fights infection Helps control body temperature • KP4: The functions of the circulatory system is to: 1. 2. 3. transport materials to and from cells such as oxygen, nutrients and wastes Fights infection Helps control body temperature • KP6: The main organs are the heart and the blood vessels! • These blood vessels help carry the nutrients to your cells and remove wastes from your cells KP7: How are the respiratory and circulatory systems related? • Heart pumps blood into the lungs where gas exchange occurs when the alveoli release the carbon dioxide from the body and takes in oxygen Oxygenated blood is then returned to the heart and the newly oxygenated blood is circulated to the rest of the body. • The circulatory system then transports the oxygen blood to cells in our tissues where the oxygen is used to help burn fuel! How are the respiratory and circulatory systems related? VIDEO! Road Check What is the oxygen pathway? a. Oxygen enters from the pharynx larynx bronchi trachea b. Oxygen enters from the nasal/mouth cavity pharynx larynx trachea bronchi alveoli c. Oxygen enters from the larynx pharynx trachea alveoli d. Oxygen enters from the mouth cavity bronchi alveoli lungs Road Check What is the oxygen pathway? a. Oxygen enters from the pharynx larynx bronchi trachea b. Oxygen enters from the nasal/mouth cavity pharynx larynx trachea bronchi alveoli c. Oxygen enters from the larynx pharynx trachea alveoli d. Oxygen enters from the mouth cavity bronchi alveoli lungs Road Check What is the purpose of the circulatory system? a. To transport oxygen from our cells and take in carbon dioxide b. To help our body move using muscles c. To transport nutrients to our cells and remove wastes from our cells d. To transport oxygen to the alveoli Road Check What is the purpose of the circulatory system? a. To transport oxygen from our cells and take in carbon dioxide b. To help our body move using muscles c. To transport nutrients to our cells and remove wastes from our cells d. To transport oxygen to the alveoli Road Check What are the main organs for the respiratory system? a. The lungs and the smooth muscles b. The skeletal muscles and the blood c. The pharynx and the blood d. The lungs and the trachea Road Check What are the main organs for the respiratory system? a. The lungs and the smooth muscles b. The skeletal muscles and the blood c. The pharynx and the blood d. The lungs and the trachea Please take out a sheet of lined paper and write. Your Name Mr. Vo September 7, 2012 Independent Practice Answer in your own words: 1. What is the function of the respiratory system? 2. What is the function of the circulatory system? 3. How are the respiratory and circulatory system related (how do they work together)? Have an awesome Rest-of-the-Day!
