What is the lining of the heart chambers?

The endocardium, the innermost layer, covers heart valves and acts as a lining of the heart chambers. It is also in contact with the blood that is pumped through the heart, in order to push blood into the lungs and throughout the rest of the body.

What lines the chambers of the heart and covers the heart valves?

The endocardium is the innermost layer of the heart and lines the chambers and extends over projecting structures such as the valves, chordae tendineae, and papillary muscles.

What connects the 4 chambers of heart?

Heart Valves. The heart has four valves - one for each chamber of the heart. The valves keep blood moving through the heart in the right direction. The mitral valve and tricuspid valve are located between the atria (upper heart chambers) and the ventricles (lower heart chambers).

What are ventricles?

ventricle, muscular chamber that pumps blood out of the heart and into the circulatory system. Ventricles occur among some invertebrates. ... In humans, the ventricles are the two lower chambers of the heart.

What is the inner lining of the heart called?

The endocardium forms the inner lining of the heart, and the flaps which form the valves of the heart.

What is fibrous pericardium?

The fibrous pericardium is a layer of connective tissue that provides support and protection for the heart. It has a number of attachments to the diaphragm, the sternum (via the sterno-pericardial ligaments), and the vertebral column.

What is Cuspid valve?

Valves of the Heart

The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves.

What is endocardium myocardium and pericardium?

The heart wall is comprised of three layers. The endocardium is the innermost layer, and the muscular middle layer is the myocardium. The epicardium is the outermost layer of the heart wall, and also the innermost layer of the protective pericardium that surround the heart.

How many chambers are in the heart?

Your heart has four separate chambers that pump blood, two on the right side and two on the left.

What chamber is divided horizontally?

The left cavity pumps blood throughout the body, while the right cavity pumps blood only to the lungs. Each cavity is in turn divided horizontally into two chambers, making a total of four chambers altogether. The two upper chambers are known as the atria, and the two lower chambers as the ventricles.

What is this cerebrum?

(seh-REE-brum) The largest part of the brain. It is divided into two hemispheres, or halves, called the cerebral hemispheres. Areas within the cerebrum control muscle functions and also control speech, thought, emotions, reading, writing, and learning.

Where is the 3rd ventricle?

The third ventricle is a narrow, funnel-shaped structure that lies in the center of the brain. It lies below the corpus callosum and body of the lateral ventricles, between the two thalami and walls of hypothalamus, and above the pituitary and midbrain (Fig. 28-1).

What is ventricular chamber?

Anatomical terminology. A ventricle is one of two large chambers toward the bottom of the heart that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs. The atrium (an adjacent/upper heart chamber that is smaller than a ventricle) primes the pump.

What is the layer of heart?

The wall of the heart separates into the following layers: epicardium, myocardium, and endocardium. These three layers of the heart are embryologically equivalent to the three layers of blood vessels: tunica adventitia, tunica media, and tunica intima, respectively.

What is the upper chamber of the heart called?

The heart has four chambers, two upper (atrium) and two lower (ventricle), with one atrium and one ventricle on both the right and left side of the heart. Blood that is returning from other areas of the body and is no longer oxygen rich, enters through the top right chamber of the heart.

What are the valve in the heart?

The four heart valves, which keep blood flowing in the right direction, are the mitral, tricuspid, pulmonary and aortic valves. Each valve has flaps (leaflets) that open and close once per heartbeat.
