Organ Systems and Homeostasis Skeletal Urinary Muscular Lymphatic Nervous Reproductive Cardiovascular Endocrine Respiratory Digestive Integumentary Homeostasis Input: Information Output: Information sent along afferent Control sent along efferent pathway to control Center pathway to effector. center. Brain Receptor Effector Receptor detects change. Skin, blood Sweat glands Response of effector feeds temp back to reduce Stimulus the effect of produces stimulus and change in returns variable variable. VARIABLE (in homeostasis) to homeostatic level. Running Cooling 2 Organ systems What processes occur in the Skin that might be considered a homeostatic ( self regulating ) mechanism Deters pathogens from entering our body Protects against injury, infection, fluid loss Helps regulate body temperature. 3  Organ systems Skeletal What processes occur in the bones that might be considered a Provide support for the body (structures). homeostatic Protects internal organs and tissue. (self regulating) mechanism Stores calcium, phosphorus, and magnesium (minerals) and fats in yellow bone marrow. Makes red blood cells Gets stronger or weaker based on need 4  Organ systems Muscles What processes occur in the muscles that might be considered a homeostatic ( self regulating ) mechanism? Maintain posture and enable various movement. Produce and regulate heat through cellular respiration. 5  Organ systems- Nervous System What processes occur in the nervous system that might be considered a homeostatic ( self regulating ) mechanism? Overall survival response through flight or fight or freeze response Body temperature Blood pressure Senses (visual, auditory, equilibrium, gustatory, and olfactory Hormone levels 6 Organ Systems What processes occur in the cardiovascular system that might be considered a homeostatic ( self regulating ) mechanism Pump blood to the body, supply body with oxygen take s away carbon dioxide transportation for hormones, nutrients, waste assists in maintaining body temperature, protect body from infections- antibodies, white blood cells Detects abnormalities in fluid levels 7 Organ Systems - Respiratory What processes occur in the respiratory system that might be considered a homeostatic ( self regulating ) mechanism? Bring oxygen to blood vessels from atmosphere Produce vocal sounds or vibrations (larynx). Expulsion of carbon dioxide Protects from illness by trapping threats (mucus) Warms/cools air to body temp 8  Organ Systems Lymphatic What processes occur in the lymphatic/ immune that might be considered a homeostatic ( self regulating ) mechanism? Absorb fluid that not able to be absorbed be picked sucked up by the CV system Regulate access fluid levels and immunity Target, destroy dangerous: bacteria, fungi, parasites and viruses Recycle dead cells and debris in our CV system 9
