Multiple Choice

Which of the following statements best describes the process of hormonal signaling?

Hormones are stored in the lymphatic system until needed by the body.

Hormones are secreted directly into the digestive tract to aid in nutrient absorption.

Hormones are released into synaptic clefts to transmit nerve impulses.

Hormones are released into the bloodstream and travel to target organs to exert their effects.

Verified step by step guidance

Understand the role of hormones: Hormones are chemical messengers produced by glands in the endocrine system. They regulate various physiological processes by traveling through the bloodstream to target organs.

Identify the incorrect statements: Hormones are not stored in the lymphatic system, nor are they secreted directly into the digestive tract or released into synaptic clefts. These statements do not accurately describe hormonal signaling.

Recognize the correct pathway: Hormones are released into the bloodstream, which serves as the transport system to carry them to specific target organs or tissues where they exert their effects.

Consider the mechanism of action: Once hormones reach their target organs, they bind to specific receptors, triggering a response that can alter cellular activity, metabolism, growth, or other functions.

Review examples of hormonal signaling: For instance, insulin is released into the bloodstream by the pancreas and travels to cells throughout the body to regulate glucose uptake and metabolism.
