Circulatory system Functions, Parts, & Facts Britannica
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.
The Heart and Circulatory System Teaching Resources
Key terms The circulatory system The circulatory system is a network consisting of blood, blood vessels, and the heart. This network supplies tissues in the body with oxygen and other nutrients, transports hormones, and removes unnecessary waste products. The heart
The Circulatory System CanadiensSchool
Overview What is the circulatory system? Your heart and blood vessels make up the circulatory system. The main function of the circulatory system is to provide oxygen, nutrients and hormones to muscles, tissues and organs throughout your body.
The Circulatory System Basicmedical Key
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.

How Open vs Closed Circulatory Systems Function
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.

Science CIRCULATORY SYSTEM
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.

Section 3 The Cardiovascular System Nitty Gritty Science
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.
Heart Anatomy ยท Anatomy and Physiology
The circulatory system is a network of blood vessels that transport blood throughout the body. The heart pumps blood through the arteries to the tissues of the body, and veins return blood from the tissues back to the heart. The circulatory system also helps to regulate the body's temperature and pH. Every minute, our heart pumps anywhere.
How does the Circulatory System Work? (with pictures)
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.

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.
