How does ADH play a role in a fluid volume deficit?
How does ADH play a role in a fluid volume deficit?
- ADH is secreted from the pituitary gland and acts as a compensatory mechanism by excreting excess fluid.
- ADH is secreted from the adrenal gland and acts as a compensatory mechanism by excreting excess fluid.
- ADH is secreted from the adrenal gland and acts as a compensatory mechanism by retaining essential fluid.
- ADH is secreted from the pituitary gland and acts as a compensatory mechanism by retaining fluid. (correct)

Study Notes
Genetics and Inheritance
- A mother with homozygous recessive genotype and a heterozygous father may have varied chances for offspring inheriting PKD.
- Fetal alcohol syndrome is a teratogenic disorder linked to excessive alcohol consumption during pregnancy.
Hormonal Regulation and Disorders
- Antidiuretic hormone (ADH) is secreted from the pituitary gland and compensates for fluid volume deficit by retaining fluid.
- Diabetic ketoacidosis (DKA) in Type 1 diabetics is primarily due to the inability to transport glucose into cells, leading to ketone accumulation.
Pathophysiology of Trauma
- Cold extremities in massive bleeding patients arise from peripheral artery constriction, reducing blood flow to limbs.
Tumor Types and Locations
- Rhabdomyosarcoma is a tumor predominantly found in skeletal muscle.
Stress Responses
- Stress hormone responses to hypoglycemia include cortisol, epinephrine, and glucagon; ADH is not released in this context.
Cellular Adaptation
- Epithelial changes in chronic smokers that revert upon cessation indicate metaplasia, an adaptive response where one cell type transforms into another.
Aging and Health Outcomes
- Increased age correlates with poorer prognosis potentially due to a deteriorating immune system.
Glycogen Metabolism Disorders
- McArdle’s disease impacts glycogenolysis, preventing glycogen breakdown.
Cellular Electrical Activity
- A shorter polar gap (RMP = -60 mV) may indicate symptoms like lethargy and weakness due to altered cellular excitability.
Disease Mechanisms
- Sickle Cell Disease involves pathophysiology characterized by abnormal cellular proliferation.
Metabolic Processes
- The conversion of glycogen to glucose by glucagon is referred to as glycogenolysis.
Antioxidative Agents
- Superoxide dismutase, Vitamin C, and Vitamin E are key substances utilized to counteract free radicals.
