What is the role of the mucous in the body?
The secreted mucous traps the pathogens in the body preventing any further activities of disease. The pathogens get expelled when the moucous is expelled.
What is the function of the synovial membrane?
Lines the joint cavity and produces synovial fluid which helps the bones move and prevent them from rubbing together.
Rheumaoid arthritis results in part from an infection and immune response in the synovial membrane. What effects does this have on the ability of this membrane to carry out its function?
It lowers the amount of synovial fluid secreted so joints arent able to move as freely.
Cutaneous Membrane: Tissue Types/ Common Location/ Functions
stratified squamous epithelium/ skin/ thick (protective), water proof, dry.
Mucous Membrane: Tissue Types/ Common Location/ Function
epithelium/ lines passageways and chambers that communicate with the exterior (digestive, respiratory, reproductive, and urinary tracts)/ reduce friction and facilitate absorption and secretions.
Serous Membrane: Tissue Types/ Common Location/ Function
areolar tissue/ internal sub divisions of ventral cavity/ minimize friction.
Synovial Membrane: Tissue Types/ Common Location/ Function
connective/ lines joint cavity/ produces synovial fluid, allows for lubrication and movement.
Occurs when the double membrane of that lines your chest cavity and surrounds each lung become inflamed. It affects homeostasis in the body because it alters breathing function.
Bacterial or fungal infection of the peritoneum (silk like membrane that lines the inner abdominal wall and covers the organs whithin the abdomen). Left intreated it can lead to severe, potentially, life threatening infection throughout your body and causing disruption in homeostasis.
The swelling and irritation of the paricardium; the thin sac that surrounds the heart.
