Textbook Question

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
Hormones that decrease blood volume and blood pressure include antidiuretic hormone and aldosterone.

Verified step by step guidance

Step 1: Begin by understanding the roles of antidiuretic hormone (ADH) and aldosterone in regulating blood volume and blood pressure. ADH promotes water reabsorption in the kidneys, increasing blood volume and pressure. Aldosterone stimulates sodium reabsorption, which also increases water retention and blood pressure.

Step 2: Evaluate the statement provided. The statement claims that antidiuretic hormone and aldosterone decrease blood volume and blood pressure. Based on their physiological roles, this claim appears to be false.

Step 3: Correct the false statement. The corrected statement should reflect the actual function of these hormones: 'Hormones that increase blood volume and blood pressure include antidiuretic hormone and aldosterone.'

Step 4: Review other hormones that decrease blood volume and blood pressure, such as atrial natriuretic peptide (ANP), which promotes sodium and water excretion, reducing blood volume and pressure.

Step 5: Conclude by emphasizing the importance of understanding hormone functions in maintaining homeostasis, particularly in the cardiovascular and renal systems.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Hormones and Their Functions

Hormones are chemical messengers produced by glands in the endocrine system that regulate various physiological processes. They play crucial roles in maintaining homeostasis, influencing metabolism, growth, and mood. Understanding the specific functions of hormones like antidiuretic hormone (ADH) and aldosterone is essential for analyzing their effects on blood volume and pressure.

Antidiuretic Hormone (ADH)

Antidiuretic hormone, also known as vasopressin, is produced by the hypothalamus and released by the posterior pituitary gland. Its primary function is to promote water reabsorption in the kidneys, which helps to increase blood volume and, consequently, blood pressure. Therefore, stating that ADH decreases blood volume and pressure is incorrect.

Aldosterone

Aldosterone is a steroid hormone produced by the adrenal glands that regulates sodium and potassium levels in the body. It promotes sodium reabsorption in the kidneys, which leads to water retention, thereby increasing blood volume and blood pressure. Thus, the assertion that aldosterone decreases blood volume and pressure is also false.
