Myocardium
<span>The heart has
four chambers, four valves. It is composed of cardiac muscles which all
in all pumps blood throughout the human body through the blood vessels.
When something gets injured around the heart, well it will
automatically, in high possibility stop functioning. Take not of the
valves and the most important is the sinoatrial node which is the pace
maker of the heart. It is what triggers the heart to pump itself and the
valves then function and the blood travels and then gets cleansed out
of carbon dioxide in the alveoli.<span> </span></span>
Answer:
Multicellular
Explanation:
Unicellular, as the prefix "uni" implies, only have ONE cell. Unicellular organisms can include bacteria, yeast, protists, etc. Multicellular organisms have many cells and are any plant or animal, as they are much larger and complex than unicellular organisms.
As for the second question, the frilled lizard is a perfect example of the ways that organs work together to form necessary organ systems. In the instance of the heart, there are cardiac muscle cells that branch and connect to each other to form cardiac muscle tissue, which has special junctions that cause the cells to contract together and in turn keep the heart pumping and the circulatory system moving.
