ADH is produced in the hypothalamus and released by the posterior pituitary gland. It causes the kidneys to retain water, constricts arterioles in the peripheral circulation, and affects some social behaviors in mammals. Source: OpenStax Anatomy and Physiology OpenStax Anatomy and Physiology Antidiuretic hormone (ADH), also known as vasopressin, controls the amount of water reabsorbed … Continue reading The Role of Antidiuretic hormone (ADH)
Source: https://www.webmd.com/urinary-incontinence-oab/ss/slideshow-why-it-hurts-to-pee OpenStax Anatomy and Physiology Water loss from the body occurs predominantly through the renal system. A person produces an average of 1.5 liters (1.6 quarts) of urine per day. Although the volume of urine varies in response to hydration levels, there is a minimum volume of urine production required for proper bodily functions. … Continue reading Regulation of Water Output in Our Body
The thirst response begins when osmoreceptors detect a decrease in water levels in the blood. Source: OpenStax Anatomy and Physiology OpenStax Anatomy and Physiology Osmolality is the ratio of solutes in a solution to a volume of solvent in a solution. Plasma osmolality is thus the ratio of solutes to water in blood plasma. A … Continue reading The Regulation of Water Intake in Our Body
An allergic reaction can cause capillaries in the hand to leak excess fluid that accumulates in the tissues. (credit: Jane Whitney) OpenStax Anatomy and Physiology Edema is the accumulation of excess water in the tissues. It is most common in the soft tissues of the extremities. The physiological causes of edema include water leakage from … Continue reading What is an Edema?
The graph shows the composition of the ICF, IF, and plasma. The compositions of plasma and IF are similar to one another but are quite different from the composition of the ICF. Source: OpenStax Anatomy and Physiology OpenStax Anatomy and Physiology The compositions of the two components of the ECF—plasma and IF—are more similar to … Continue reading Composition of Body Fluids
The intracellular fluid (ICF) is the fluid within cells. The interstitial fluid (IF) is part of the extracellular fluid (ECF) between the cells. Blood plasma is the second part of the ECF. Materials travel between cells and the plasma in capillaries through the IF. Source: OpenStax Anatomy and Physiology The chemical reactions of life take … Continue reading The Body Fluid Compartments

Under certain conditions, they may differentiate into tissue-specific or organ-specific cells with special functions. In some cases, stem cells may continually divide to produce a mature cell and to replace themselves. Stem … Continue reading Stem Cells and Repair of Kidney Damage
