What three types of tissue make up your heart?
epicardium = the top layer that is actually 2 layers myocardium= the middle layer also the muscle endcardium= the inner most layer that seperates blood from muscle
What are segments of the walls of the Heart?
The walls of the heart are made up of three layers of cardiac muscle called epicardium, myocardium, and endocardium. These muscle layers are made up of different things. The outermost layer is the thin epicardium muscular covering of the heart. This layer is made up of mostly connective tissue and fat. The inside layer is a thick layer of muscle called the myocardium which is made up of cardiomyocytes, excitable cells that can propagate quickly and can spread their action potentials to surrounding cells. Each cell can physically contract to make the heart muscle shorten. This is the largest layer and accounts for about 80% of the heart. The inner lining muscle layer of the heart is a smooth membrane called endocardium. It is made up of endothelial cells just like the linings of the blood vessels.
Is Earth's weather the thin layer of gases that surrounds Earth?
No, the weather is weather. The ATMOSPHERE is the thin layer of gases.
What is The thin outer layer of the earth?
the crust
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.
Are there layers of the heart?
The layers of the HEART {outermost-innermost} 1. Epicardium {This is the outer layer is also known as VISCERAL PERICARDIUM and contains fat, which helps to cushion the heart} 2. Myocardium {This middle layer is the thickest layer of the wall and is made primarily of cardiac muscle} Endocardium {This innermost layer is thin and very smooth, and stretches as the heart pumps blood}
What it the smooth shiny innermost lining of the heart?
The smooth layer of cells lining the inside of the heart is the endocardium. It provides protection for the heart chambers and valves.
Which is the innermost layer of heart which is in contact with blood flowing through its chambers?
The innermost layer of the heart that is in contact with the blood flowing through its chambers is the endocardium. This layer is a thin membrane that lines the inner surface of the heart chambers and valves, helping to regulate blood flow and prevent clot formation within the heart.
Which description of the endocardium?
The endocardium is the innermost layer of the heart, lining the heart chambers and covering the heart valves. It is composed of a thin layer of endothelial cells and a supporting layer of connective tissue, providing a smooth surface that minimizes friction as blood flows through the heart. This layer also plays a role in regulating heart function and maintaining the overall health of the cardiac tissue. Additionally, the endocardium is involved in the formation of the heart's electrical conduction system.
The innermost layer of the pleura is known as the?
The innermost layer of the pleura is known as the visceral pleura. It is a thin membrane that covers the lungs and attaches to the surface of the lungs.
Lining of the heart is called what?
Endocardium

Where is the pina mater located?
I think you mean pia mater which is the innermost layer of the meninges. It is a thin layer that is attached to the brain and spinal cord and has many blood vessels and neurons.
Innermost layer of the pleura is known as?
The innermost layer of the pleura is known as the visceral pleura. This thin membrane covers the surface of the lungs and is in close contact with the lung tissue.
What is the thin layer of tissue which surround the human heart is known?
The pericardium.
Where is endocardium located?
The endocardium is a thin layer of tissue that lines the inside of the heart chambers and heart valves. It is located beneath the myocardium (muscle layer) and covers the inner surface of the heart.
What are the walls of the aorta made of?
The aorta is the largest artery in your body.It is made up of 4 significant sections:Lumen - The gap in which the blood travels away form the heart. In an artery this is smaller than a vein.Tunica intima - This is a thin layer on the innermost section of the artery. It is made up of squamous epithelium cels, allowing the blood to move quickly across them at a high pressure.Tunica media - This is the layer in the middle of the artery. This is the thickest layer of the three. It is mostly made up of smooth muscle fibres and collagen fibres.Tunica externa - This is the outermost layer. It is mostly made up of collagen fibres, though it does have a few smooth muscle fibres.This applies to all arteries, not just the aorta.
