The circulatory system

divided into:

  • The cardiovascularsystem, which consists of the heart, blood vessels, andblood
  • Lymphaticsystem, which consists of lymphaticvessels and lymphoid tissues within the spleen, thymus, tonsils, and lymph nodes.
functions of the circulatory system
Functions of the Circulatory System
  • Transportation.

a. Respiratory.

b. Nutritive.

c. Excretory.

d. Regulatory.

  • Protection.
  • protects against injuryand foreign microbes or toxins
  • The clotting mechanism protects against blood loss in vessel damage

  • The peripheral portions of the ANS are subdivided into thesympathetic and parasympathetic divisions.

Functions:

(1) movement

(2) heat production

(3) body support andmaintenance of posture

muscle attachment
Muscle Attachment
  • Skeletal muscles are attached to a bone on each end by tendons
  • Tendon: composed of dense regular connective tissue

binds a muscle to the periosteum of a bone.

  • When muscle contractsit shortenstension on its

tendonsand attached

bones

  • Insertion more movable bony attachment of themuscle
  • Originless movable attachment of the muscle
