Pelvic and Pectoral Girdle
Appendages that are attached to our vertebral column so that we can physically interact with our environment.
Provides foundation for attachment of the legs to the vertebral column. Made up of paired coxal bones. Each coxal bone is made up of three individual bones known as the Ilium - ischium - pubis.
Large wing-like bone (similar to the scapula or shoulder blade of the upper body) that provides muscular support for abdominal structures (hip bone). One of the bones that make up the coxal.
Important landmark as the superior point of attachment for the inguinal ligament which runs from the crest of the iliac to the joining of the two pubic bone.
Inferior most segment of the spinal column. Consists of 4 fused vertebrae which articulate at the inferior aspect of the sacrum.
Also called the shoulder girdle includes the scapula and clavicle structures.
Attached to the superior sternum. Runs from that attachment laterally to join with the scapula (winglike structure) and provides anterior support for the shoulder by its articulation with the scapula.
Gas exchange units . Spongy elastic connective tissue with a rich vascular (arterial and venous networks)supply and air sacs.
Communication from the lungs with the external environment is via this respiratory passageway.
Space that occupied the heart, trachea, major blood vessels, nerves, thymus gland, lymph nodes, and conducting portion of the gastrointestinal tract (esophagus).
Posterior to the trachea. Long collapsed tube - food tube - maintains this collapsed condition until food bolus passes through then the bolus is propelled by gravity and peristaltic contractions into the stomach.
Functional units of the lung where the gas exchange takes place. Subdivisions of the Bronchial tree end here.
Highly vascularized and provide the mechanism by which oxygen enters the blood stream and carbon dioxide is removed.
