    Study Notes

    Lymphatic System

    • Main functions: Fluid capture, fluid balance, infection fighting (using lymph nodes to capture bacteria).
    • Supports circulatory system by removing toxins and waste products via a parallel system.
    • Lymphoid organs: Tonsils, spleen, thymus, lymph nodes.

    Digestive System

    • Function: Process food, extract nutrients, eliminate waste.
    • Major organs: Stomach, small intestine, large intestine.
    • Accessory organs: Liver, gallbladder, pancreas, spleen, appendix.
    • Pathway: Mouth → esophagus → stomach → small intestine → large intestine (colon) → rectum → anus.
    • Nutrient extraction begins in small intestine.
    • Bile from liver aids in food breakdown.
    • Large intestine processes waste culminating in excretion from anus.
    • Abdominal quadrants:
      • Right upper: Liver, gallbladder
      • Left upper: Stomach, spleen, pancreas
      • Right lower: Appendix, female reproductive structures
      • Left lower: Large and small intestines (spanning all four quadrants).

    Integumentary System (Skin)

    • Functions: Protection (barrier from environment), water balance, temperature regulation, excretion, shock absorption, impact protection.
    • Layers:
      • Epidermis: Outermost (dead cells).
      • Dermis: Functional layer (nerve endings and structures).
      • Subcutaneous layer: Fatty layer (insulation, shock absorption, energy storage).

    Endocrine System

    • Function: Distribute hormones throughout the body.
    • Organs release hormones into bloodstream, triggering responses in other body parts.
    • Examples:
      • Adrenal glands: Epinephrine and norepinephrine (fight-or-flight).
      • Pancreas: Insulin (glucose regulation/digestion).
      • Ovaries: Estrogen (female functions).
      • Testes: Testosterone (male functions).
    • Epinephrine and norepinephrine effects:
      • Beta-1 receptors: Increase heart rate and force.
      • Beta-2 receptors: Dilate bronchioles.
      • Alpha-1 receptors: Constrict peripheral blood vessels.

    Renal (Urinary) System

    • Function: Regulate fluid levels, filter toxins, maintain pH balance.
    • Primary organ: Kidneys (located in retroperitoneal space, adjacent to lower back).
    • Pathway: Blood filtration by kidneys → waste products into bladder → excretion through urethra.
    • Ureter: Tubes transporting urine from kidneys to bladder.
    • Urethra: Tube excreting urine from bladder.

    Reproductive Systems

    • Male: Testes (produce sperm), penis (external reproductive organ, urination).
    • Female: Ovaries (release eggs), fallopian tubes (connect ovaries to uterus), uterus (houses fetus), vagina (birth canal).
    • Egg fertilization, embryo/fetus development in uterus, culminating in birth through vagina.
