What is found in 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.

What membranes are around the heart?

Let's start from the inside of the heart out:Endocardium - the inner layer of the heart that lines the chambers that fill with blood in the heart. This is a single layer of cells called endothelia.Myocardium - this is the muscle of the heart and is a thick layer of muscle cells that contract to create pressure within the chambers of the heart to pump the blood.Epicardium - also called visceral layer of serous pericardium, is a single mesothelial layer of cells that lines the heart and is continuous with the parietal layer of serous pericardium, forming a fluid filled sac.Pericardial cavity - the fluid filled cavity surrounding the heart.Parietal layer of serous pericardium - the serous membrane external to the pericardial cavity.Fibrous pericardium - the tough external layer of the heart that is continuous with the great vessels of the heart and central tendon of the diaphragm.

Where do you find smooth muscle cell?

Smooth muscle cells appear as thin layer of sheets and are found in the the walls of blood vessels.

Blood is carried back to the heart by?

Blood is not carried to the heart. The heart is where all the red blood cells are made. The heart pumps blood that is made directly inside the heard or the second layer of the bones which feels like a sponge.

How does blood move in the arteries?

The movement of blood is caused by the pumping of the heart. The heart is a muscle. Arteries are tough on the outside and smooth on the inside. An artery actually has three layers: an outer layer of tissue, a muscular middle, and an inner layer of epithelial cells. The muscle in the middle is elastic and very strong. The inner layer is very smooth so that the blood can flow easily with no obstacles in its path. The muscular wall of the artery helps the heart pump the blood. When the heart beats, the artery expands as it fills with blood. When the heart relaxes, the artery contracts, exerting a force that is strong enough to push the blood along. This rhythm between the heart and the artery results in an efficient circulation system. Source-

Chamber walls of the heart?

The outside tissue layer of the heart is called the pericardium. The actual muscle of the heart is called the the cardiac muscle, and the inside tissue layer that lines in the the chambers of the heart is called the endocardium.

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}

Do capillaries have more smooth muscle than arteries or veins?

capillaries by definition don't have any smooth muscle in their walls. They are simply made of one layer of endothelial cells.

Do any of the following cells lack a plasma membrane simple squamous epithelium human red blood cells sperm cells teased smooth muscle cells?

Animal cells all have a plasma membrane. Used to just be called the "cell membrane" and separates plants from animals in that plants have a cell wall and animals have the plasma membrane. This is the selectively permeable lipid bi layer found in all cells and is what keeps extracellular material outside the lipid bi layer and keeps the organelles inside the cell.

What is the internal layer of tissue in the heart?

It's a very thin layer, similar to the endothelial cells of blood vessels. It's called endocardium.
