The first organisms believed to have developed a heart-like structure are thought to be early vertebrates, specifically within the group of jawless fish known as agnathans, which emerged over 500 million years ago. These primitive hearts were simple muscular tubes that pumped blood, evolving over time into the more complex structures seen in modern vertebrates. The development of the heart was crucial for efficient circulation, supporting increased metabolic demands as organisms became larger and more active.

What is the first organism to develop in the embryo?
The first organ to develop in the embryo is the heart. In a fetus, there is a brain, but it isn't fully developed and can't understand signals from the nervous system. Therefore the first functional organ would be the heart. But the first thing to start developing in a fetus is the nervous system. ( no that isn't an organ )
What is the first organ formed in the fetus?
The heart is the first organ to develop in a fetus. Together, blood and the circulatory system, that is powered by the heart, form the first organ system.
What is the first organ in the fetus to develop?
The Heart.
What organism is a heart?
The heart is not an independent organism, but a muscle.
Which is develop first heart or brain?
Both at the same time but the brain works before the heart pumps
Is a heart an organism?
It is organ, not an organism.
Is a heart a organism?
It is organ, not an organism.
Does the heart or brain develop first in the fetus?
Both the same time but the brain functions before the heart pumps

The heart is one of the first parts on the embryo to develop. what part of the stem cell provides instructions for building the heart?
DNA
What will happen to an organism if it does not grow or develop?
what will happen to organisms if they do not grow and develop
How does a cell develop into a multicellular organism?
as a multicellular organism develops, its cells as a multicellular organism develops, its cells
