Summary Introduction

To review:

The role of antidiuretic hormone (ADH) on the epithelial cells of the kidney in making it more permeable to water.

Introduction:

Hormones are the chemical signals that regulate different physiological processes. They are secreted by the exocrine and endocrine glands. The exocrine glands release their chemicals in the ducts that transport them to the required sites, whereas the endocrine glands release their secretions into the blood from where they are carried to the sites.

Answer a, Anti-Diuretic Hormone (ADH) and Aldosterone both target kidney cells and increase water retention (keeping water in the blood, letting less go out with urine).  ADH causes water retention directly- kidney cells let more water move from the urine back into the blood (the cells are a barrier between those two spaces).  Aldosterone enhances water retention by causing more sodium to be retained, creating a stronger osmotic gradient.  However, aldosterone also causes a loss of potassium to the urine for every sodium that is kept in the blood. a. Are these hormones both water-soluble or fat-soluble, or is there one of each? b. What chemical class does each belong to? c. Draw a picture hypothesizing how each might cause its target cells to have their effects.  Don't look it up!  You have all the information you need from the notes and explanation in this question to come up with a reasonable, logical hypothesis. d. If somebody has hyper-aldosteronism (secrete too much aldosterone,…
Atrial Natriuretic Peptide helps to reduce overall blood pressure in a variety of ways.  One way is by increasing Glomerular Filtration Rate. a. Why/how would increasing GFR cause decreased blood pressure? b. To increase GFR, would Atrial Natriuretic Peptide cause constriction or dilation of afferent arterioles at the kidneys?  The efferent arterioles?
Renin is secreted in response to hypovolemia or to an increase in the osmolality of the blood. Provide three possible mechanisms by which these conditions may stimulate rennin secretion. What are the consequences of increased rennin secretion that lead to increased aldosterone secretion? Present this sequence of events. Why are angiotensin converting enzyme inhibitors (ACEIs) used as a common therapy for hypertension? How do they influence blood pressure? Are plasma levels of renin elevated or depressed in a patient with Conn’s disease? Why?
