HAPPY FRIDAY, SCHOLARS! Write “No HW” in your agenda and take out last night’s homework. Put everything under your desk except for a pencil. Silently complete the Do Now on your desk.

HW Review blood heart artery muscle cell muscle cell carbon dioxide The _________ is pumped through the body by the ________. It moves away from the heart and towards the _____________ in an _________ . When it reaches the ______________, it exchanges the oxygen for ___________________ in a _____________. It then carries the carbon dioxide to the lungs in a ______. When it reaches the lung, it exchanges the carbon dioxide with __________. Then it moves to the heart to be pumped again. heart artery muscle cell muscle cell carbon dioxide capillary vein oxygen

Do Now Review What should you do if you disagree with a partner? How should you work when working with a partner?

What is our AIM today? SWBAT differentiate between functions and parts of the respiratory, digestive, and circulatory systems.

Body Systems Review Today, we will work in pairs to complete timed review activities. Use your notes to help you complete your work successfully.

Section 1: Respiratory System You will have 10 minutes to complete this section with a partner. Do not move on to other sections if you are finished.

Section 1: Respiratory System What is the main function of the respiratory system? What are the important parts of the respiratory system? What happens to the oxygen once it is in the lungs? What is the job of the diaphragm?

Section 1: Respiratory System nose trachea lungs diaphragm

Section 1: Respiratory System Sometimes when I get frustrated, I take deep breaths. I _________ for ten seconds and then __________ for ten seconds. When I inhale, I breathe __________. The oxygen goes in my nose, and travels down my ___________ to get to my _________. Once it is in my lungs, red blood cells pick it up to be taken to ________ all over my body. Then, red blood cells bring carbon dioxide back to my lungs. This carbon dioxide is _________. I breathe it out. After I take my deep breaths, I usually feel much better. inhale exhale oxygen trachea lungs cells waste

Section 1: Respiratory System TRUE ________ The main function of the respiratory system is to breathe in oxygen and out carbon dioxide. _________ The diaphragm helps your lungs contract when you breathe in and expand when you breathe out. _________ The main parts of the respiratory system are the nose/mouth, trachea, lungs, diaphragm, and the red blood cells. _________ Carbon dioxide is waste created when body cells have used oxygen as energy. expand FALSE contract FALSE TRUE

Section 2: Circulatory System You will have 10 minutes to complete this section with a partner. Do not move on to other sections if you are finished.

Section 2: Circulatory System What is the main function of the circulatory system? What are the three important parts of the circulatory system? Why do red blood cells deliver oxygen to body cells all over your body? Explain the differences between arteries and veins.

Section 2: Circulatory System blood vessels heart blood cells arteries red BC veins white BC capillaries platelets

Section 2: Circulatory System B D F E A C

Section 2: Circulatory System Yesterday, I went for a long run. As I was running, my ________ started pumping harder and harder. It did this because my muscle cells were working extra hard and needed more __________. The __________________ would pick up oxygen from the ________ and deliver it all over my body to be used as energy. The red blood cells would leave the heart in an artery and then return towards the heart in a vein. They would exchange the oxygen for carbon dioxide inside of a ____________. heart oxygen red blood cells lungs capillary

Section 2: Circulatory System FALSE ________ The main function of the circulatory system is to take oxygen all over the body . _________ The 3 main parts of the circulatory system are arteries, veins, and capillaries. _________ When you are exercising, your heart starts pumping harder to deliver carbon dioxide all over your body. ^ and nutrients FALSE blood, the heart, and vessels FALSE oxygen

Section 3: Digestive System You will have 10 minutes to complete this section with a partner. Do not move on to other sections if you are finished.

Section 3: Digestive System What is the main function of the digestive system? What are the important parts of the digestive system? What is the difference between digestion and absorption? What happens to the nutrients, water, and minerals once they are absorbed into the blood?

Section 3: Digestive System mouth esophagus stomach large intestine small intestine

Section 3: Digestive System B F D C A

Section 3: Digestive System Last night, I had the most delicious dinner! I had chicken tacos and ice cream for dessert. First my _________ broke down the food into smaller pieces. Then, it traveled down my _____________ into my ___________. In there, the food was ___________ into smaller nutrients by stomach acid. After the stomach, the food moved into my __________________ where nutrients will be ____________ into my blood stream. My red blood cells will deliver ____________ to cells all over my body. Finally, the remains will move into the __________________ where water and minerals will be absorbed into the blood stream. Anything remaining will leave my body as waste. mouth esophagus stomach digested small intestine absorbed nutrients large intestine
