Question

For a cell to respond to a ligand released from a cell and uses the circulatory system to get to the responding cell, it is called ______ communication.

A) Paracrine
B) Autocrine
C) Juxtacrine
D) Endocrine

Answer 1

In endocrine communication, ligands travel through the circulatory system to reach distant responding cells, playing a key role in long-distance cellular communication.

Step-by-step explanation:

For a cell to respond to a ligand released from a cell and uses the circulatory system to get to the responding cell, it is called endocrine communication. This type of chemical signaling involves hormones secreted into the extracellular fluid that diffuse into the blood or lymph and travel throughout the body to distant target cells. The endocrine system is responsible for this form of long-distance communication in the body.
