From the sinus venosus the blood flows into the atrium. Blood flowing through the circulatory system transports nutrients oxygen and water to cells throughout the body.

Circulatory system blood flow through the heart. Your heart is divided into four chambers. Veins are vessels of the circulatory system that support circulation by conveying blood to the heart. Blood is then ejected ejection phase when the ventricles contract and pump the blood into the arteries.
After moving through the pulmonary circuit oxygen-rich blood in the left ventricle leaves the heart via the aorta. Blood is pumped into the aorta which carries oxygenated blood around the body. So when the blood initially flows into the heart it needs to be stopped in the Atrium and the Ventricle before being pushed out of the heart.
Blood is what keeps the rest of our body alive. It must be continuously pumped through the body by the heart. This blood is circulated from the aorta to the rest of the body by various major and minor arteries.
Blood flows from the right atrium into the right ventricle through the tricuspid valve. The atrium is the largest of the chambers in the fish heart and only weakly muscular. Blood then flows from both upper atriums left atrium and right atrium into the two lower chambers left and right ventricles which then expand.
Blood leaves the heart through the pulmonic valve into the pulmonary artery and flows to the lungs. As the heart beats it pumps blood through a system of blood vessels called the circulatory system. The heart normally extracts 70 to 75 percent of the available oxygen from the blood in coronary circulation which is much more than the amount extracted by other organs from their circulationseg 40 percent by resting skeletal muscle and 20 percent by the liver.
Blood flows through the heart in the following order. For more information visit. The journey might begin and end with the heart but the blood vessels reach every vital spot along the way.
DEOXYGENATED blood returns to your heart through the SUPERIOR VENA CAVA and INFERIOR VENA CAVA to your RIGHT ATRIUM Capillaries separate oxygenated blood from deoxygenated blood and arteries from. This animation features the heart and circulatory system and how they work. Blood circulation begins when the heart relaxes between heart beats.
The systemic circuit is the path of circulation between the heart and the rest of the body excluding the lungs. The cardiovascular system delivers nutrients throughout the body. The vessels are elastic tubes that carry blood to every part of the body.
The ventricle is the only well muscled chamber nearly as large as the atrium. The vessels are elastic tubes that carry blood to every part of the body. It pushes the blood with weak contractions in the ventricle.
It is the work horse of the heart its contractions drive the blood around the body. The three main components of the cardiovascular system are the heart blood vessels and blood. As the heart beats it pumps blood through a system of blood vessels called the circulatory system.
This unidirectional flow of blood through the heart shows that mammals have a double circulatory system. This means that there needs to be a reliable barrier between the Atrium and Ventricle which is why there are three flaps. When the ventricle is full the tricuspid valve shuts to prevent blood flowing backwards into the atrium.
Together your heart and blood vessels make up your cardiovascular system which circulates blood and oxygen around your body. The circulatory system also called the cardiovascular system or the vascular system is an organ system that permits blood to circulate and transport nutrients such as amino acids and electrolytes oxygen carbon dioxide hormones and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases stabilize temperature and pH and maintain homeostasis. These include two on the right called the right atrium and right ventricle and two on the left called the left atrium and left ventricle.
