PHA Biology 9 Moretti & Dickson CIRCULATORY SYSTEM

 Transport O 2 and nutrients to the different cells of the body  Remove CO 2 and other waste materials from the bloodstream  Link to CELL RESPIRATION: Cells need to get the Oxygen from the lungs to cell respiration to produce ATP Cells need to get the Oxygen from the lungs to cell respiration to produce ATP Carbon Dioxide produced from cell respiration needs to get to the lungs to be exhaled through Respiratory System (gas exchange). Carbon Dioxide produced from cell respiration needs to get to the lungs to be exhaled through Respiratory System (gas exchange). Purpose of the Circulatory System Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body

Structures of the Circulatory System: Heart  Almost entirely muscle.  Two pumps:  Right side: pumps blood to Lungs  Left side: pumps blood to Body  Atria: upper chambers/ receive blood  Ventricles: lower chambers/ pump blood to body Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body

 Arteries:  Function  Bring blood away from the heart to the body (highway)  Most have strong walls to handle high blood flow/ pressure  Structure:  Range in size from very large to quite small  Walls are lined with smooth muscle & elastic tissue Structures of the Circulatory System: Blood Vessels Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body

 Capillaries:  Function:  Exchange materials from the blood with other body tissues  Deliver nutrients and oxygen to body tissues  Absorb waste products (like CO 2 ) from body tissues  Structure:  Smallest type of blood vessels (side streets)  Thin walls = easy for materials to move across wall  Thickness = big enough for 1red blood cell to fit single file Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body Structures of the Circulatory System: Blood Vessels

 Veins:  Function  Bring blood toward the heart after it has passed through the capillaries. (highway)  Most have strong walls  Blood moves in a one-way loop back to heart  Structure  One way valve system that keeps blood flowing towards the heart  Range in size from very large to quite small  Walls are lined with smooth muscle & elastic tissue Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body Structures of the Circulatory System: Blood Vessels

 Homework:  Tonight: Heart Dissection Reflection Paragraph – on separate paper  Do Now:  Get an apron and gloves  Sit with your lab group  Clear tables of everything else  Complete the Heart Dissection Pre-Lab  Today’s Objectives:  Explore the anatomy of a real heart!  Compare what you know about the heart to the real thing. Bio 9C: Wednesday, Title: Heart Dissection Lab

Function of the Circulatory System: Circulation

Heart Dissection – Materials  Aprons, goggles & gloves  Dissecting tray  Extra beaker – for dumping excess liquid  Scalpel – caution, these are sharp! Never cut towards fingers!  Scissors – often these are better for cutting than the scalpel  Adult pig heart

Heart Dissection - Rules  Respect for the animals that donated these hearts  Safety  Raw meat… keep hands away from mouth, wash hands after.  Scalpels are sharp!  Patience – this might be confusing. That’s OK! You can learn a lot even if you can’t figure out all the parts.  Zero tolerance for fooling around, horseplay, etc.  You WILL be asked to leave

Heart Dissection: Reference Materials

 Homework: *Do this on a separate sheet of paper or type it!  Revise the essay you began by writing on Tuesday and “completed” for today. For the continuation of the story, follow the molecule of oxygen from the alveoli in the lungs through the circulatory system. The story should end with a molecule of oxygen being “dropped off” at the mitochondrion of a cell in the body for cell respiration. Your story should use and make connections between the following vocabulary: Capillary, Vein, Heart, & Artery  Do Now:  What are the major differences between arteries and veins? Answer: Arteries bring blood away from the heart; Veins bring blood to the heart (remember A = AWAY (arteries); Vein – “in” the heart)  Today’s Objectives:  Describe the major structures and functions of all organs in the Circulatory System  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body Bio 9C: Thursday, Title: Circulatory System: Structures & Functions

Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body Blood:  Components  Red Blood Cells  Contain Hemoglobin  Carry Oxygen  White Blood Cells  Fight Infection  Platelets  Proteins that clot blood  Plasma  The fluid all of these float in  90% water  10% other stuff: salts, gases, enzymes, hormones, etc. Structures of the Circulatory System: Blood White Blood Cell w/ Red Blood Cells

Blood: White Blood Cell w/ Red Blood Cells Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body Structures of the Circulatory System: Blood

 Start on Right Side of the Heart:  Blood is pumped from heart to the lungs by arteries.  No Oxygen – full of CO 2  Blood drops off carbon dioxide. Gets oxygen.  Oxygen rich blood returns to left side of heart by veins  Full of Oxygen Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body Function of the Circulatory System: Circulation

Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body Structures of the Circulatory System: Circulation

 Left Side of the Heart:  Blood is pumped from heart to the rest of the body by arteries.  Full of Oxygen  Blood drops off oxygen for other cells to do cell respiration. Picks up carbon dioxide.  Blood returns to Right Side of Heart by veins  No Oxygen – full of CO 2 Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body Function of the Circulatory System: Circulation

Circulatory System Activity: Roadmaps and the Circulatory System The Task: Examine maps from different cities, towns, and countries. Identify how the transportation systems have been created to move goods and services from place to place. Describe how this is similar to the human circulatory system Option 1: Group Analysis Every person in the group needs to have the following in their notebooks: What are the maps your group examined? Imagine you needed to deliver a package from the outskirts of the city to the downtown area. On one of the maps, trace a path you would take to do so. Think about how these transport systems have been created to move things around based on road sizes, direction of traffic, density of people, etc… How is our internal “transportation system” similar and different than our actual transportation system? Option 2: Group Activity One product per group: As a group, develop a song, rap, poem, or short story to describe how goods and services move throughout the body. As a group, present this to the class. The more creative the better! Objectives for Class:  Describe the major structures and functions of all organs in the Circulatory system  Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO 2 from body
