Textbook Question

Match the following hormones with their correct descriptions.
Leptin
Atrial natriuretic peptide
Melatonin
Estrogens
Erythropoietin
Testosterone
a. Produced by the pineal gland; regulates the sleep/wake cycle
b. Produced by the kidneys; regulates red blood cell production
c. Produced by the heart; promotes sodium ion loss in the kidneys and vasodilation
d. Produced by the testes; promotes androgenic and anabolic actions
e. Produced by adipose tissue; promotes satiety
f. Produced by the ovaries; regulate the menstrual cycle and the development of secondary sex characteristics

Verified step by step guidance

Step 1: Identify the hormone 'Leptin' and match it with its description. Leptin is produced by adipose tissue and is responsible for promoting satiety. Match it with description (e).

Step 2: Identify the hormone 'Atrial natriuretic peptide' and match it with its description. This hormone is produced by the heart and promotes sodium ion loss in the kidneys and vasodilation. Match it with description (c).

Step 3: Identify the hormone 'Melatonin' and match it with its description. Melatonin is produced by the pineal gland and regulates the sleep/wake cycle. Match it with description (a).

Step 4: Identify the hormone 'Estrogens' and match it with its description. Estrogens are produced by the ovaries and regulate the menstrual cycle and the development of secondary sex characteristics. Match it with description (f).

Step 5: Identify the hormone 'Erythropoietin' and 'Testosterone' and match them with their descriptions. Erythropoietin is produced by the kidneys and regulates red blood cell production (b), while Testosterone is produced by the testes and promotes androgenic and anabolic actions (d).

Key Concepts

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

Hormonal Functions

Hormones are chemical messengers produced by glands in the endocrine system that regulate various physiological processes in the body. Each hormone has specific functions, such as regulating metabolism, growth, reproduction, and mood. Understanding the role of each hormone is crucial for matching them with their descriptions.

Endocrine Glands

Endocrine glands are specialized organs that secrete hormones directly into the bloodstream. Key glands include the pineal gland, kidneys, heart, testes, and ovaries, each producing hormones that influence different bodily functions. Recognizing which gland produces which hormone is essential for accurately identifying their descriptions.

Hormonal Interactions

Hormones often interact with each other and can have synergistic or antagonistic effects on bodily functions. For example, estrogens and testosterone play roles in sexual development and reproductive health, while leptin influences appetite and energy balance. Understanding these interactions helps in comprehending the broader implications of each hormone's function.
