— digestive: constipation, diarrhea
— respiratory: asthma, bronchitis, emphysema
— excretory: kidney disease, gout
• — hardening of arteries: raises blood pressure
— diarrhea: results in dehydration

Structure 1
• ribosome • site of protein synthesis • amino acid — used to make proteins • nucleus — the ribosome gets
instructions from the nucleus determining which proteins are produced by the cell
Structure 2
• nucleus • control of cell processes • DNA — makes up the chromosomes in the nucleus
• ribosome — nucleus sends instructions to ribosomes for protein synthesis
Structure 3
• mitochondrion • site of energy release/cell respiration • ATP — produced in the mitochondrion
• cell membrane — allows glucose to enter cell and be used by the mitochondrion for energy release
