Y3V-T1-LSN8

Homeostasis & water regulation

Learning Goals LSN7:

• I know examples of homeostasis in the human body.
• I know how our body regulates sugar levels.

Apply the sensor-controller-effector model to blood glucose regulation. name all three.

Learning Goals LSN8:

• I know how our body regulates water levels.
• I can name and explain how nutrients and diets can have an effect on your kidneys

Key words:

• Endocrine system 
• Hypothalamus
• Pituitary gland
• Kidney
• ADH

• homeostasis
• negative feedback
• positive feedback
• sensor
• controlor
• effector

Homeostasis

All organs and organ systems working together,creating a balance inside your body.

Negative and positive feedback loops are used to maintain this balance. 

Receptors: The process begins with osmoreceptors in the hypothalamus that monitor blood osmolarity. 

Control Center: The hypothalamus serves as the control center, processing the information from the osmoreceptors. 

Effector: The posterior pituitary gland is the effector, which either increases or decreases the secretion of ADH. 

Response: The kidneys are the final target, adjusting their water reabsorption based on the levels of ADH.
