Today is Thursday, September 27, 2012 Homework: - Read Chapter 3, Lesson 2 for tomorrow -Chapter 3 Packet (Due SATURDAY) -Complete heart diagram Warm-Up: Copy the following definitions into your notebook…..
RBC = Red Blood Cell, transports oxygen, nutrients, carbon dioxide, and other waste. WBC = White Blood Cell, fights germs (literally eats them). Platelets = Parts of cells that clot the blood, cause scabs, help in the healing process. Plasma = The liquid part of your blood that carries the blood cells (REMEMBER, MOST OF YOUR BODY IS WATER).

Parts of the circulatory system Part of the circulatory system?
Artery
Transports blood?
Keeps blood flowing in one direction?
Smallest blood vessel
Goal • SWBAT Demonstrate an understanding of the structure and function of the circulatory system by taking notes and discussing this system. Today’s focus will be blood vessels and the heart.

- Thick walls -Under extreme pressure from heart (remember, the heart is the central pump for the whole system) - If artery is cut you will bleed out and die very quickly – blood can shoot out of your body up to one or two meters - Job is to take oxygen-rich blood away from your heart and into all parts of your body -Protected deep in body

YES
-Smallest blood vessel in your body -Capillaries in the lungs are only ONE RED BLOOD CELL (RBC) WIDE. -Incredibly small -Oxygen/nutrient and carbon dioxide/waste exchange occurs in capillaries

- Generally near the outside of body - Have thinner walls than arteries - Not under as much pressure as arteries - If you cut a vein, you will bleed, but blood will not come shooting out - Veins have valves to prevent backwards flow of blood - Veins are blue or purplish blue because blood in the veins is full of carbon dioxide

Review
Types of Blood Cells
Review
• RBC = Red Blood Cell, transports oxygen, nutrients, carbon dioxide, and other waste • WBC = White Blood Cell, fights germs (literally eats them) • Platelets = Parts of cells that clot the blood, cause scabs, help in the healing process • Plasma = The liquid part of your blood that carries blood cells (REMEMBER, MOST OF YOUR BODY IS WATER)
-RIGHT ATRIUM Collects blood full of carbon dioxide and other waste from body from Vena Cavas.
Right Ventricle Collects blood from Right Atrium and pumps it to the Pulmonary Artery, which leads to the lungs. In the lungs carbon dioxide will be removed and oxygen will be added. Only artery in your body that contains carbon dioxide rich blood.
Left Atrium Collects oxygen rich blood from the Pulmonary Veins. Pulmonary Veins are the ONLY veins in your body that carry oxygen-rich blood!!!!!!
Left Ventricle Collects oxygen rich blood from the Left Atrium and pumps it into the Aorta, your body’s largest artery, which will carry it out into your body.
The Goal….AGAIN!!!! • SWBAT Demonstrate an understanding of the structure and function of the circulatory system by taking notes and discussing this system. Today’s focus will be blood vessels and the heart.
Turn to your shoulder partner….
…..and tell them one thing you learned today about the circulatory system.
Right now…. • Complete handout • Draw a picture of the human heart in your OWN SCIENCE NOTEBOOK. Please label your diagram.
