Microscope observations
__ 1.Tap water __ I saw many cells that I couldn’t name. __ 2.Pond water __ I noticed that it had more cell that the tap water. __ 3.Leaf __ I noticed that it had some kind of worm on it. __ 4.Deal leaf __ I saw water cells even tough it looks dry. ** Conclusion: ** Everything seems to be made up of cells and smaller pieces. Such as water, air and maybe other things you cant see with the naked eye.

Human Cells Challenge
 How do human cells get the things they need to survive?

How do they get food? From the food our bodies digest. The blood carries the food to the cells.  How do they get water?  I think they get water from the water we drink  From the blood around it How do they get oxygen? I think they get the oxygen from the water or the oxygen we take in.  The blood caries the gases the cells need. How do they get rid of waste? I think the waste goes through the disposal system or anus. The blood takes away the waste. 

Circulatory&Respiratory Systems
Video
 * 3 hundred million air sacs in lungs
 * lungs look like upside down tree
 * lung tubes are called bronchi
 * cardiovascular system is made up out of blood the heart and bronchi
 * people donate blood
 * blood types a b o ab
 * white cells only live a couple of days
 * scab is made by plasma
 * 1/5 of the air around you is oxygen
 * left side of the heart has oxygenated blood
 * left side of the heart has deoxygenated blood
 * each drop of blood contains 8 million white blood cells and 5 million red blood cells

CIRCULATORY SYSTEM REVIEW
Answer these questions: 1. What are the basic needs of all living cells? 2. How do the cells in multicellular organisms get the resources they need to stay alive?  The blood carries it for them. Good 1/2 3. What is the main function of the left side of the human heart?  The left side of the heart receives oxygenated blood from the lungs and pumps it to the rest of the body. Good x 4. What is the main function of the right side of the human heart?  The right side of the heart receives deoxygenated blood from all parts of the body except for the lungs. Good 1/2 5. What is the function of the red blood cells?  They carry oxygen around your body .Good x 6. What are the main kinds of blood vessels and what functions do they perform?

Food, water, gas exchange, and waste removal! 2. Blood flowing through the circulatory system delivers nutrients and removes waste 3. It collects blood from the lungs and pumps it to the body tissues. 4. It collects blood returning from the body tissues and pumps it out to the lungs. 5. They carry oxygen from the lungs to the cells, and carbon dioxide from the cells to the lungs. 6. Arteries carry blood away from the heart. Veins carry blood to the heart. Capillaries touch all cells and carry out gas exchange and nutrient delivery. 7. Red blood cells release carbon dioxide for elimination and pick up oxygen for delivery. 8. Cells take water, food (sugar), minerals, and oxygen from the blood and transfer wastes to the blood.

Discussion after Video
1. Your heart beats faster when you play sports because you need more oxygen. 2. The lungs need to have oxygen so they can give to red blood cells to pass it on. 3. They need oxygen to keep active and to get rid of the carbon dioxide. 4. Platelets rush to make a fibrin which blocks the rest of the platelets and the red blood cells. 5. If you lose to much blood the cells can't live because the blood is needed to give water, food, oxygen and to take away the waste. 6. White blood cells which kill bacteria. == Pigs Heart Dissection

== 1. Why do people eat food? <span style="font-size: 120%; color: rgb(232, 33, 225);"> People eat food because it is a necessary of life ad it provides energy. 2. What happens to food in the digestive system? <span style="color: rgb(232, 33, 225);">In the digestive system food is broken up into food the cells can use. <span style="color: rgb(232, 33, 225);"> 3. Describe the path taken by food as it passes through the digestive system. <span style="color: rgb(232, 33, 225);">First it goes down the esophagus than to the stomach then the small and large intensities and finally out the anus. <span style="color: rgb(166, 8, 8);">Teeth cut mash and grind large pieces of food into small particles. Saliva mixes with the food to start the chemical breakdown. Then it is swallowed. Then it heads down he esophagus.The food moves into the small and large intestines. 4. Explain what happens to food at each place in the digestive system. <span style="font-size: 110%; color: rgb(166, 8, 8);">In the mouth the food is broken into smaller pieces. In the small intestine the he food i changed into nutrients the cells can use. In the large intestine the water is taken out of the food and the remaining material is composed of fiber indigestible material an dead bacteria. <span style="font-size: 120%; color: rgb(232, 33, 225);">5. How does digested food get to cells? Through the blood. <span style="color: rgb(166, 8, 8);">The food pass through the millions of capillaries in the small intestine. 6. Why do people need kidneys? <span style="color: rgb(232, 33, 225);">People need kidneys because they are need to keep the body clean. <span style="color: rgb(166, 8, 8);">If the waste builds up the environment would soon be unfit ti support living cells. <span style="color: rgb(166, 8, 8);"> 7. Describe how kidneys work. <span style="color: rgb(232, 33, 225);">Kidneys clean the cells. <span style="color: rgb(166, 8, 8);">Kidneys act like filters separating the cellular waste from the blood. ==

Digestive and Excretory
the food to get through the small intestine
 * a lot of hydrochloric acid
 * digestive system starts when thought smell or taste of food is present
 * stomach has thick layer mucus to protect itself from acid
 * more than 1.5 liters of salvias produced in one day
 * the tube that the food goes through is the esophagus
 * takes 3-10 hours for
 * people produce more than 1 liter of glass a day
 * kidneys hardly as big as your hand

Glossary == Cell- Is the basic unit of life Oxygen- Is an atmospheric gas needed to support life. Carbon Dioxide- A waste gas made by every living things Pulse- The result of the blood being pushed through blood vessels by the beating of the heart. Heart- The organ that pumps the deoxygenated blood to the lungs and the oxygenated blood around the body Blood Vessels- The arteries, veins and the capillaries that carry the blood around the body Blood- Is a liquid that flows to and from the cells in the blood vessels. The human heart has four chambers-right atrium,left atrium,left ventricle and the right ventricle. Circulatory System- includes tissues( blood and blood vessels)and organs(heart) that transport life-support substances to cells AND removes waste. Respiratory System- includes the tissues and organs (lungs) tat provide gas exchange(02 & CO2)
