What function in the earthworm has a similar function as the human heart?
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.
What is the function of the ventricle?
The ventricles of the heart function to pump blood to the entire body. Right ventricle: receives blood from the right atrium and pumps it to the pulmonary artery (to lungs). Left ventricle: receives blood from left atrium and pumps to aorta (to rest of body). Hoped this helped byee!! :)
Which layer of the heart is responsible for contraction in order to pump blood?
myocardium
How many walls does the heart has?
The heart wall is richly supplied with blood vessels, and it is composed of three layers: the epicardium, the myocardium, and the endocardium.First layer--Epicardium is the visceral layer of the serous pericardium. It is often infiltrated with fat, especially in older people.Middle layer--Myocardium ("muscle heart") is composed mainly of cardiac muscle and forms the bulk of the heart. It is the layer that contracts.Third layer--Endocardium ("inside the heart") is a glistening white sheet of endothelium (squamous epithelium) resting on a thin connective tissue layer. Located on the innermyocarial surface, it lines the heart chambers and covers the fibrous skeleton of the valves. Endocardium is continuous with the endothelial linings of the blood vessels leaving and entering the heart.
What is the medical term meaning muscular layer of the heart?
Myocardium.
Functions of myocardium?
pumping blood and gives morphine
The layer of the heart responsible for pumping blood is called the?
myocardium
What does enlarged myocardium indicate?
It indicates that the heart is pumping against resistance and is undergoing stress. It can show high blood pressure or hypertension.
What is the function of a cardiac muscle?
Helps in pumping the blood
Trace the pathway of a drop of blood from the myocardium of the heart to the arm?
The myocardium does not have blood flow to the arm. The myocardium is the muscle of the heart and therefore only supplies blood to the heart.
Function of cardiac muscles?
The function of cardiac muscle is to pump blood.
What does myocardium receive it's blood supply directly from?
The myocardium receives blood from the coronary arteries.
Which coronary artery supplies blood to the inferior myocardium?
The Right Coronary Artery supplies blood to the inferior myocardium
Where is myocardial tissue?
You have three layers in the heart. Outer layer is pericardium, middle layer is myocardium and inner layer is endocardium. Myocardium is composed mainly of cardiac muscles, connective tissue and blood vessels.
Where does heart get energy to pump blood?
From the blood it is pumping, the blood pervades are organs and carries food /energy for those organs to function.
What layer of the heart actually pumps blood?
The myocardium (middle layer) has the bulk of the muscle which pumps blood from the ventricles.
Where does blood enter the myocardium?
Oxygenated blood is brought to the myocardium by coronary arteries. These arteries are located all around he surface of the heart.
