1. CELLULAR RESPIRATION CONNECTIONS
The purpose of cellular respiration is to make ATP, energy storage molecules used to provide the energy for all reactions and processes in all of the cells throughout the organism

2. Cellular Respiration is connected to the RESPIRATORY system
O2 IN
CO2
OUT
The RESPIRATORY system and cellular RESPIRATION both are involved with gas exchange. Oxygen is in input and carbon dioxide is an output. Your lungs/breath pull air into the body to send oxygen to the cells, and the carbon dioxide waste from the cells is delivered to the lungs so that you can breath/exhale it out of the body. The cells take in oxygen to use for cellular respiration in the mitochondria and carbon dioxide waste leaves the cell.

3. Cellular Respiration is connected to the CIRCULATORY SYSTEM
ALL CELLS TAKE IN OXYGEN, AND GET RID OF CARBON DIOXIDE WASTE
The circulatory system is all of your blood vessels carrying all kinds of molecules throughout the body to wherever they are needed, and carrying away any wastes so the body can get rid of them. This is connected to cellular respiration because the blood carries oxygen from the lungs to the cell, and carries carbon dioxide from the cells to the lungs.
BLOOD VESSELS DELIVER THE OXYGEN AND CARRY AWAY THE CARBON DIOXIDE

4. Cellular Respiration is connected to the DIGESTIVE SYSTEM
Your digestive system (which includes what?) breaks your food down into smaller particles, small enough to be able to enter a cell This process starts with chewing and continues through the stomach and intestines. Enzymes in your saliva, stomach, and intestines help to chemically break down food, while the organs churn and squeeze the food to mix it with these enzymes. Eventually, when all the food is tiny molecules, like sugars, it can then be used for cellular respiration.

5. Cellular Respiration is connected to the CIRCULATORY SYSTEM
OUTSIDE of INTESTINE
INSIDE of
INTESTINE CONTAINING FOOD
(Orient students to the inside and outside of the intestine as shown in this image) In order to get to the cells, millions of tiny blood vessels carry blood throughout the lining of the intestine to pick up the tiny food molecules and carry them to all the cells all over the body. This is how glucose molecules get to each cell for cellular respiration.
BLOOD VESSELS PICKING UP FOOD MOLECULES

6. Cellular Respiration is connected to the MUSCULAR system

7. Cellular Respiration is connected to PHOTOSYNTHESIS
Inputs of one are outputs of the other
Special structures with membranes
Matter is recycled
Energy flows through from light to ATP
Special structures, involving special membranes

8. Cellular Respiration is connected to EXERCISE
Uses up oxygen and ATP quickly
FERMENTATION: KEEPS MAKING ATP WITHOUT OXYGEN
Anaerobic
Makes less ATP per glucose molecule
Produces lactic acid
Makes muscles sore
Switches back to aerobic respiration when oxygen replenishes
