The innermost layer of the heart is called the endocardium. The endocardium lines the chambers where the blood circulates and covers the heart valves. If you had an arrhythmia youd feel it.

The middle layer the tunica media is primarily smooth muscle and is usually the thickest layer. In certain regions the. The heart contains three basic layers similar to those seen in arteries and veins.

Or they may beat too quicklymore than 100 beats per minute. The second or middle layer known as the myocardium is made up of contractible muscles and it is this contraction which creates the pumping and beating effect which we call the heart rate. The outermost layer is the epicardium which is derived from the proepicardium from the septum transversum.

The heart also has a wall that is composed of three layers. The outer layer is the tunica adventitia or tunica externa. Layers of GI tissue.

The stomach is capable of dilating to accommodate more than one litre about one quart of food or liquids without increasing pressure on the stomach. It is composed of collagen and elastic fiber connective tissues. The epidermis is the outermost layer and the hypodermis or subcutaneous layer is the innermost layer.

The primary function of the hypodermis is to act as an insulator for regulating the body temperature.

It lines the lumen of the digestive tract. The innermost layer the tunica intima also called tunica interna is simple squamous epithelium surrounded by a connective tissue basement membrane with elastic fibers. The sac which surrounds the heart called the pericardium can become inflamed in a condition known as pericarditis.

The middle layer is composed of smooth muscle and is called the tunica media. Serous layer or serosa. Smooth muscle in this layer allows the venae cavae to receive input from the nervous system.

The skin consists of layers called the epidermis dermis and hypodermis. The third and innermost layer endocardium combines with the endothelium or inner surface of the blood vessels that envelop the valves of the heart. This layer hosts fat and connective tissues that house larger blood vessels and various nerves.

It is made of simple squamous epithelium called. Germ layer any of three primary cell layers formed in the earliest stages of embryonic development consisting of the endoderm inner layer the ectoderm outer layer and the mesoderm middle layer. The mucosa consists of epithelium an underlying loose connective tissue layer called lamina propria and a thin layer of smooth muscle called the muscularis mucosa.

Since the mucosa is the innermost layer within the GI tract it surrounds an open space known as the lumen. Innermostdeepest layer of the heart Lines the heart chambers and the valves Smooth thin lining to reduce friction of blood flow through the chambers Cardiac conduction system located in this layer Image source See slide 28. The inner layer is.

The innermost layer of the heart wall the endocardium is joined to the myocardium with a thin layer of connective tissue. The germ layers form during the process of gastrulation when the hollow ball of cells that constitutes the blastula begins to differentiate into more-specialized. Most carry oxygen-rich blood away from the heart and deliver it to various organs and tissues.

Arteries are blood vessels. Layers of the Heart Endocardium. The outer layer epicardium thin layer the middle layer myocardium thick layer and the innermost layer endocardium thin layerThe.

Subcutaneous layer is also known as hypodermis. On the mucosa layer small finger-like projections called villi and microvilli help to increase surface area for nutrient absorption. Note the mucosa located at the innermost layer.
