what are the different parts of the heart and their function?

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. On the right side of the heart, the right atrium and ventricle work to pump oxygen-poor blood to the lungs.

functions: separates the abdominal and thoracic cavities and it draws air into the lungs. function: pumping chambers of the heart; the right side pumping oxygen-poor blood to the lungs and the left side pumping oxygen-rich blood to the body.

The cardiovascular system can be thought of as the transport system of the body. This system has three main components: the heart, the blood vessel and the blood itself. The heart is the system's pump and the blood vessels are like the delivery routes.

There are many functional units in the human heart. Unlike the skeletal muscles, we cannot call the sarcomere of the cardiac muscles as the only functional unit. The cardiac muscles of the left atrium and the right atrium have are primarily designed to receive and store blood.

The right part of our heart has an atrium and one ventricle, while the case is the same for the left side too. The walls of the ventricles are thicker, while that of the atria are thinner. They however contain valves to pump the blood in and out of the heart.

The primary function of the heart is to pump oxygen rich blood to organs such as the brain, liver, and kidneys as well as all other tissue. The heart of the frog is different from the hearts of warm-blood animals such as humans.

Things to remember. The circulatory system delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood on different sides. The types of blood vessels include arteries, capillaries and veins.

An Introduction to the Cardiovascular System The cardiovascular system can be thought of as the transport system of the body. This system has three main components: the heart, the blood vessel and the blood itself. The heart is the system's pump and the blood vessels are like the delivery routes.

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

Major Functions of the Cardiovascular System. On this page we take a closer look at the four major functions of the cardiovascualr system - transportation, protection, fluid balance and thermoregulation.

Your heart is made up of three layers of tissue: Pericardium – a thin outer lining that protects and surrounds your heart. Myocardium – a thick muscular middle layer that contracts and squeezes blood out of your heart. Endocardium – a thin inner lining.

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.

Find out all about the blood, lungs and blood vessels that make up the circulatory system. 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 circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.
