Document Summary
Ventral- thoracic, diaphragm, abdominal cavity pericardial cavity (heart), Dorsal- pleural cavity (lung), cranial cavity, spinal cavity.

Serous: lines every organ in the ventral cavity (except spinal cord) Secretes fluid to prevent friction between organs and body wall. Synovial: lines moveable joints (knees, ankles, elbows) to reduce friction. Cutaneous/skin: serves as membrane for entire body, protection and water loss prevention. When the desired value/rage of hormone release is reached, effectors are shut off. What are the receptors, control center, and effectors in regulating body temperature: receptor detects change, control center in the brain decides response, effector: carries out plan from control center. Control center: sweat, increase blood to skin, decrease blood to core. Effectors: sweat glands produce sweat, dilate blood vessels to skin, constrict blood vessels to core.
