ANATOMY OF THE HUMAN ABDOMEN
The abdominal wall Encloses the abdominal cavity. Divided into anterolateral and posterior sections. The abdominal wall Functions Forms a firm flexible containment for the abdominal viscera in the abdominal cavity and assists the viscera in maintaining their anatomical position against gravity. Protects the abdominal viscera from injury. Assists in forceful expiration by pushing the abdominal viscera upwards. Involved in actions like coughing, vomiting, defecati...

ADAPTATIONS OF THE RESPIRATORY SYSTEM TO ITS FUNCTIONS
PopularHistological Adaptations of Respiratory system to its Functions General Organizational Pattern of Respiratory System Respiratory system is organized into the following layers; 1. Mucosa Layer • The respiratory mucosa is made up of the epithelium and supporting lamina propria (a thin layer of connective tissue) • Lamina propria contains elastin and collagen fibers, which provide the trachea with support and elasticity. NB/ Along the respiratory pathway, the epithelial lining changes t...
