1. Nitric Oxide (NO)

Function: Vasodilation, increases blood flow
Impact: Lowers blood pressure, improves oxygen delivery, prevents clot formation

2. Acetylcholine (ACh)

Function: Neurotransmitter for muscle activation and memory
Impact: Controls muscle contractions, enhances cognitive function, regulates the autonomic nervous system

3. Dopamine

Function: Neurotransmitter involved in reward, motivation, and movement
Impact: Regulates mood, motor control (deficiency leads to Parkinson’s disease), and addiction pathways

4. Serotonin (5-HT)

Function: Mood regulation, appetite, sleep
Impact: Low levels cause depression and anxiety; also regulates bowel movements

5. Epinephrine (Adrenaline)

Function: Fight-or-flight hormone

Function: Neurotransmitter and hormone involved in alertness and blood pressure control
Impact: Increases focus, arousal, and vasoconstriction

7. Cortisol

Function: Stress hormone regulating metabolism and immune response
Impact: Increases glucose levels, suppresses immune system, and affects mood

8. Glucagon

Function: Raises blood glucose levels
Impact: Prevents hypoglycemia by breaking down glycogen in the liver

9. Insulin

Function: Lowers blood glucose levels
Impact: Facilitates glucose uptake into cells, prevents diabetes

10. Histamine

Function: Inflammatory response and allergic reaction mediator
Impact: Causes vasodilation, increases permeability of blood vessels, leads to swelling and itching

11. Prostaglandins

Function: Inflammatory mediators, pain, and fever regulation
Impact: Involved in blood clotting, uterine contractions, and immune response

12. Endorphins

Function: Natural pain relievers
Impact: Reduce pain, induce euphoria (like after exercise – "runner’s high")

Function: Sleep-wake cycle regulator
Impact: Induces sleep, regulates circadian rhythm

14. Oxytocin

Function: "Love hormone" involved in bonding and childbirth
