The Circulatory System Its 4 Main Parts and How They Work Owlcation

Your heart is the primary organ of your circulatory system. It pumps blood throughout your body, controls your heart rate and maintains blood pressure. Your heart is a bit like a house. It has walls, rooms, doors, plumbing and an electrical system. All the parts of your heart work together to keep blood flowing and send nutrients to your other.

Heart & Circulatory System Diagram, Parts & Function, For Kids

Function The main function of the circulatory (or cardiovascular) system is to deliver oxygen to the body tissues, whilst simultaneously removing carbon dioxide produced by metabolism. Oxygen is bound to molecules called haemoglobin that are on the surface of the red blood cells in the blood.

Circulatory System Charts

Main Features of the Human Circulatory System. A liquid, blood, to transport nutrients, wastes, oxygen and carbon dioxide, and hormones. Two pumps (in a single heart): one to pump deoxygenated blood to the lungs and the other to pump oxygenated blood to all the other organs and tissues of the body; A system of blood vessels to distribute blood throughout the body

Circulatory function

heart, organ that serves as a pump to circulate the blood.It may be a straight tube, as in spiders and annelid worms, or a somewhat more elaborate structure with one or more receiving chambers (atria) and a main pumping chamber (ventricle), as in mollusks. In fishes the heart is a folded tube, with three or four enlarged areas that correspond to the chambers in the mammalian heart.

Blood, by definition, is a fluid that moves through the vessels of a circulatory system. In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets.. At the top of the diagram is a cell labeled hematopoietic stem cell. There are 2 arrows pointing down from.

As seen in the diagram above, the circulatory system spans the entire body. As it moves blood around the system, it is both bringing oxygen to the tissues and carrying away the waste products they create.The circulatory system also has many functions related to delivering hormones, allowing the passage of immune cells, and other functions related to coordinating and maintaining a multicellular.

The Circulatory System CanadiensSchool

Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body. The journey might begin and end with the heart, but the blood vessels reach every vital spot along the way. These arteries, veins, and capillaries make for a vast network of pipes. If you were to lay out all the blood vessels of.

Definition of Coronary Heart Disease 17

1. The Heart Wall Is Composed of Three Layers The muscular wall of the heart has three layers. The outermost layer is the epicardium (or visceral pericardium). The epicardium covers the heart, wraps around the roots of the great blood vessels, and adheres the heart wall to a protective sac. The middle layer is the myocardium.

Heart wall There are three layers of the heart wall. The epicardium is the heart wall's outer layer, the myocardium is the middle — and muscular — layer, and the endocardium is the heart's.

The Heart and Circulatory System Teaching Resources

Heart anatomy. The heart has five surfaces: base (posterior), diaphragmatic (inferior), sternocostal (anterior), and left and right pulmonary surfaces. It also has several margins: right, left, superior, and inferior: The right margin is the small section of the right atrium that extends between the superior and inferior vena cava .

How does the Circulatory System Work? (with pictures)

1. Heart Heart is the primary muscular pumping organ which pumps out the blood in the artery (known as aorta) from where the blood is supplied to the whole body via a number of arterial tributaries. The total amount of blood pumped out from heart per unit time is known as 'cardiac output'

Pulmonary Circulation Recall that blood returning from the systemic circuit enters the right atrium ( Figure 20.23) via the superior and inferior venae cavae and the coronary sinus, which drains the blood supply of the heart muscle. These vessels will be described more fully later in this section.
