Study Notes

Tissue Types and Functions

  • Epithelial tissue is responsible for secretion and absorption.
  • Connective tissue includes tendons and holds organs in place.
  • Muscle tissue is involved in contraction.
  • Nervous tissue is responsible for communication within the body.

Feedback Loops

  • Thermoregulation is an example of a negative feedback loop.
  • Blood clotting is an example of a positive feedback loop.

Homeostasis

  • Homeostasis refers to the body's ability to maintain a constant internal state despite external changes.

Blood Vessels

  • Arteries carry blood away from the heart.
  • Capillaries are involved in the exchange of materials by diffusion with nearby cells.
  • Veins carry blood back to the heart and have one-way valves to prevent backflow.
