Summary Introduction
To examine: Whether the statement “Some heart cells and kidney cells secrete hormones” is true or false.
Introduction: In multi-cellular organisms, hormones are a certain class of signaling molecules that are produced by glands and transported throughout the body by the circulatory system. Hormones have specified the physiological and behavioral function. They travel through blood vessels and reach their target organs to perform their regulatory function. Different cells present in body secrete hormones for executing allotted functions. Heart and kidney cells also secrete some hormones to perform specific functions.

Hormones are special lipids. They are big molecules that circulates through systems in limited time and quantity. Account for this fact.
QUESTION 1
Which statement is accurate?
Hormones that differ in effect reach their target cells by different routes through the body
Pairs of hormones that have the same effect are said to have antagonistic functions
Hormones are often regulated through feedback loops
Hormones of the same chemical class usually have the same function
I choose : They have large effects on target tissues relative to their concentrations. And I got it wrong please help.

Group of answer choices Blood can carry all the same hormones throughout the body simultaneously, producing responses all over the body; nerve cells can only target a small number of cells. Nerve cells and blood work together. The endocrine has nothing to do with the nervous system. Endocrine hormones only target a very small number of precise responses. A single hormone can target many different responses, whereas a nerve only targets a single response.arrow_forwardWhich of the following best explains how hormone antagonists work?
