Heart structure and function can also be described by the Cardiac Cycle. The visceral layer of the serous membrane forms the epicardium. It pumps blood around the body at different speeds and at different pressures according go the bodys needs.

The sinuatrial and atrioventricular nodes are connected through the internodal conduction pathways providing fast action potentials transmission. Blood delivers oxygen hormones glucose and other components to various parts of the body including the human heart. Myocardium- Middle muscular layer forming atria and ventricles.

Your heart is the primary organ of your circulatory system. Article in Spanish Author F Torrent-Guasp 1 Affiliation. Name the heart valves and describe their location function and mechanism of operation.

One of the primary functions of the human heart is to pump blood throughout the body. Prevent back flow of blood from left ventricle into left atria. The two small upper chambers are the atria.

The structure and function of the heart arteries veins and capillaries is vital for the circulatory system to work. The two little smaller upper chambers are called atria and the larger lower chambers are called. Your heart is a bit like a house.

The human heart is a four-chambered muscular organ shaped and sized roughly like a mans closed fist with two-thirds of the mass to the left of midline. The right-hand side of the heart is responsible for pumping deoxygenated blood to. It has four chambers which contract in a specific order allowing the human heart to pump blood.

During the time that the SA Node has the electricity the Atria in the heart contract. Describe the structure of the human heart with a neat labelled diagram. These layers are surrounded by the pericardium a thin outer lining protecting your heart.

The heart is a large muscular pump and is divided into two halves - the right-hand side and the left-hand side. The functions of each part are as follows. Endocardium- Covers inner surfaces of heart including valves Describe the structure and functions of the four heart chambers.

Think of the hearts position like an upside down pyramid with the apex below the base. It has walls rooms doors plumbing and an electrical system. The right ventricle is the major pumping chamber on the lower right side of the heart that ejects.

One of the primary pumping chambers of the heart located in the lower portion of the heart. The right atrium links to the right ventricle by the tricuspid valve. It sends electricity currents to the AV Node in the heart.

The heart consists of four chambers right and left atria above right and left ventricles. A small body of specialized muscle tissue in the wall of the right atrium of the heart that acts as a pacemaker by producing a contractile signal at regular intervals.
