what are the different parts of your heart?

Heart Chambers, Valves, Vessels, Wall and Conduction System. The heart is made up of four chambers. The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides.

Inner layer of the heart (lines the atria and ventricles and covers the heart valves) and contains blood vessels. Has 3 sublayers: Endothelium - innermost portion a simple squamous epithelium. Smooth Muscle and Connective Tissue - middle layer of the endocardium is mix of connective tissue and smooth muscle.

The heart consists of four chambers, two atria (upper chambers) and two ventricles (lower chambers). There is a valve through which blood passes before leaving each chamber of the heart. The valves prevent the backward flow of blood.

The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels.

Your heart is actually a muscular organ. An organ is a group of tissues that work together to perform a specific function. In the case of your heart, this function is pumping blood throughout your body. Additionally, the heart is largely made up of a type of muscle tissue called cardiac muscle.

Cardiovascular system. The cardiovascular system is made up of three main parts - the heart, the blood vessels and the blood that flows through them.

Happy Heart Month, everyone! The human heart is the most incredible muscle in the body, beating about 100,000 times to send 3,600 gallons of blood through 75,000 miles of blood vessels each day.

The Heart. The heart itself is made up of 4 chambers, 2 atria and 2 ventricles. De-oxygenated blood returns to the right side of the heart via the venous circulation. It is pumped into the right ventricle and then to the lungs where carbon dioxide is released and oxygen is absorbed.

The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.

The Heart Wall: The wall of the heart is composed of three layers, the thin outer epicardium, the thick middle myocardium, and the very thin inner endocardium.

['Epicardium (outer layer) consists of epithelium + connective tissue.', 'Myocardium (middle layer) cardiac muscle layer.', 'Endocardium (inner layer) consists of endothelium + connective tissue.']

The essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood.

['The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.', 'The right ventricle pumps the oxygen-poor blood to the lungs.', 'The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.']

Humans have a four-chambered heart consisting of the right atrium, left atrium, right ventricle, and left ventricle. The atria are the two upper chambers.

The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).

The heart's location is erroneously thought to be the left side of the chest, but your heart is actually located nearly in the center of your chest, behind your sternum and between your two lungs.

['The heart is located in the center of the chest, and its function is to keep blood flowing through the body. ... ', "The brain is located in the head and functions as the body's control center. ... ", 'The two kidneys are located in the back of the abdomen on either side of the body.']
