Describe the Blood Flow of the Heart

The human heart is connected with blood vessels coming from around the body. Blood Throught the Heart Blood Flow Through the Heart Beginning with the superior and inferior vena cavae and the coronary sinus the flowchart below summarizes the flow of blood through the heart including all arteries veins and valves that are passed along the way.

. In summary from the video in 14 steps blood flows through the heart in the following order. The Heart In your body blood flows within a closed circuit of blood vessels. The SVC collects blood from the upper half of the body.

Blood supplies the body with oxygen and nutrition and eliminates carbon dioxide and wastes. Oxygenated blood flows back to the heart through the pulmonary vein back into your left atrium. Blood enters the heart through two large veins the inferior and superior vena cava emptying oxygen-poor blood from the body into the right atrium.

14 Steps of Blood Flow Through the Heart. Describe the flow of blood through the heart of human beings Deoxygenated blood from different organs comes to the right atrium through the vena cava. From right atrium it goes through the tricuspid valve to the right ventricle.

Blood Flow All blood enters the right side of the heart through two veins. From the atrium oxygen-rich blood empties into the left ventricle through another valve mitral valve. This pumping of blood goes through a complex process where in the deoxygenated blood or impure blood is cleansed and oxygenated blood or pure blood is sent throughout the body.

The right side gathers the deoxygenated blood coming from your body. 1 body 2 inferiorsuperior vena cava 3 right atrium 4 tricuspid valve 5 right ventricle 6 pulmonary arteries 7 lungs 8 pulmonary veins 9 left atrium 10 mitral or bicuspid valve 11 left ventricle 12. As we previously learned.

Blood flow through the heart is a result of differences in pressure created by blood flow as well as depolarizationcontraction and repolarizationrelaxation. Blood then enters into the RIGHT VENTRICLE 5. Your blood flows via the heart in two individual loops.

Blood enters the heart through two large veins the inferior and superior vena cava emptying oxygen-poor blood from the body into the right atrium of the heart. Superior and inferior vena cavae and the coronary sinus 2. Describe the flow of blood through the heart.

As blood circulates throughout the body oxygen is used up and the blood becomes oxygen-poor. Oxygen-poor blood returns from the body to the heart through the superior vena cava and. When the ventricles are full the tricuspid valve shuts.

From the right ventricle it goes through the pulmonary semilunar valves to the pulmonary trunk 4. Blood leaves the SVC and the IVC and enters the right atrium RA 3. When the ventricle is full the tricuspid valve shuts to prevent blood flowing backwards into the atrium.

Blood flows from the right atrium into the right ventricle through the tricuspid valve. The heart pumps blood to all parts of the body. Next we will look at each step.

As the atrium contracts blood flows from your. Healthy heart blood flow patterns. The following phase is called the ejection period which is when both ventricles pump the blood into the large arteries.

The blood flows from both atria the upper two chambers of the heart into the ventricles the lower two chambers which then expand. Chambers of the Heart. Blood enters the right atrium from the superior and inferior venae cavae and the coronary sinus.

As the atrium contracts blood flows from your right atrium into your. Pathway of blood through the heart 1. From the body to the heart.

Blood enters into the RIGHT ATRIUM 3. Blood leaves the heart through the pulmonic valve into the pulmonary artery and flows to. The normal blood flow is a cycle that flows like this.

The heart is a large muscular organ which constantly pushes oxygen-rich blood to the brain and extremities and transports oxygen-poor blood from the brain and extremities to the lungs to gain oxygen. The left ventricle is a powerful muscle that contracts to pump blood into the systemic circulation. The IVC collects blood from the lower half of the body.

It pumps it to your lungs where the carbon dioxide is released and oxygen is picked up. From the right atrium blood goes to the right ventricle. Blood circulation starts when the heart relaxes between two heartbeats.

The superior vena cava SVC and the inferior vena cava IVC see figure 3. Blood is able to circulate around your body thanks to a muscular pump known as your heart. Figure B below shows dark bluish blood low in oxygen flowing back to the heart after circulating through the body.

The blood is pumped into the blood vessels through the heart. Blood comes into the right atrium from the body moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. Then it is squeezed through the TRICUSPID VALVE 4.

After picking up oxygen the. This prevents blood from flowing backward into the atria while the ventricles contract squeeze. Blood flows from your right atrium into your right ventricle through the open tricuspid valve.

The tricuspid valve between the right atrium and. Left Side Blood flows from your left atrium into your left ventricle through the open mitral valve. The left side of your heart is your left side and the right one is your right side.

The un-oxygenated blood this is blood that has been used up by your body and needs to be resupplied with oxygen enters the heart through the SUPERIOR AND INFERIOR VENA CAVA. They are known as the right and left side loops.
