In earthworms, the structure that functions similarly to the human heart is the dorsal blood vessel. This vessel acts as a pump, circulating blood throughout the worm's body. Unlike the human heart, which is a muscular organ, the dorsal blood vessel contracts rhythmically to propel the blood, helping to transport nutrients and oxygen to various tissues.
it acts as a heart for an earthworm.... <3
yes
Blood
The function of a cow's heart is the same as a human heart - to circulate blood throughout the body. The cow's heart is very similar to a human heart in structure.
No heart muscles are different from arm muscles. They are not same either structure vise or by function wise , both have seperate entity and function.
yes
The actual "pumping system" of a worm can be mistaken as a heart, but it has no chambers. They are actually aeortic arches that pump the blood down the ventral side of the worm and it returns on the dorsal vessel.
The heart
Blood
The pulmonary artery is a structure that is located in the heart. Its' function is to transport deoxygenated blood from the heart to the respiratory system.
The structure and function relate because what the structure is made of infuences what the organ's function is. An example is that the heart is made of strong muscle cells. Therefore, it is fit to do the job of pumping blood around the body.
The structure of the heart is very complex. Cardiac myocytes and intercalated discs follow the function of cardiac muscle tissue and the heart make up part of this very complex system
