Body systems

• The formula for anaerobic respiration is C6H12O6 -> 2C3H6O3 (Glucose -> Lactic acid)
• The formula for aerobic respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water)
• Lactate buildup can cause muscle fatigue, cramps, or soreness.
• Veins carry deoxygenated blood back to the heart, the exception of the pulmonary vein
• The biggest bone in your body is the femur, in your leg
• Antagonistic muscles are muscles that opposes the action of another. For example, when the bicep contracts, the tricep relaxes, and vice versa
• Alveoli are tiny air sacs at the end of the bronchioles. The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
• Oxygenated and deoxygenated blood diffuse in and out of the capillaries into the alveoli and vice versa
• Capillaries are small vessels with thin walls that allow for easy diffusion between tissues and blood
• Arteries have thicker walls than veins because they need to be able to handle high pressure as they pump blood away from the heart
• Aorta is the largest artery in the human body
• The right side of the heart pumps blood to the lungs while the left side of the heart pumps blood to the rest of the body
• Valves prevent backflow by allowing blood to flow forward but not backward
• Pulmonary artery carries deoxygenated blood from the heart to the lungs
