    What is the role of the lymphatic system?

    The lymphatic system is a vital network that works alongside the circulatory system, primarily focused on maintaining fluid balance, removing toxins and waste, and fighting infections.

    What is the main purpose of the digestive system?

    The digestive system's primary function is to process ingested food, break down nutrients, and absorb them into the body. It also eliminates waste products.

    What are some accessory organs of the digestive system?

    The liver, gallbladder, pancreas, spleen, and appendix are considered accessory organs of the digestive system, contributing to nutrient absorption and waste elimination.

    Describe the pathway of the digestive system.

    The digestive system follows a specific pathway: Mouth -> Esophagus -> Stomach -> Small Intestine -> Large Intestine -> Rectum -> Anus.

    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.
