Human Physiology/The cardiovascular system   Deoxygenated blood from the body enters the right atrium. It flows through the tricuspid valve into the right ventricle. Contraction of the ventricle then closes the tri … cuspid valve and forces open the pulmonary valve.Blood flows into the pulmonary artery.fter oxygenation, blood is carried to the left side of the heart via the pulmonary veins. The left ventricle pumps the oxygenated blood through the aorta, the largest artery in the body, to the rest of the body. The aorta branches into smaller arteries, which branch into arterioles, which branch into capillaries.

Heart Anatomy The right ventricle receives blood from the right atrium across the tricuspid valve, which is located in the large anterolateral (ie, sinus) portion of the right ventricle. The right ventricle discharges blood into the pulmonary artery across the pulmonic (semilunar) valve located in the outflow tract (infundibulum). The inflow tract (sinus) and outflow tract (infundibulum) of the right ventricle are widely separated.

- Deoxygenated blood travels through the veins called the inferior vena cava and superior vena cave into the right atrium. Blood flows from the right atrium, through a val…ve and into the right ventricle and into the pulmonary arteries. From the pulmonary arteries the blood is carried to the lungs. So the answer is pulmonary artery.

Heart In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium. The heart pumps blood with a rhythm determined by a group of pacemaking cells in the sinoatrial node. These generate a current that causes contraction of the heart, traveling through the atrioventricular node and along the conduction system of the heart.

Ventricles of the Brain Overview. The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the following images).he largest cavities of the ventricular system are the lateral ventricles. Each lateral ventricle is divided into a central portion, formed by the body and atrium (or trigone), and 3 lateral extensions or horns of the ventricles. The central portion or the body of the ventricle is located within the parietal lobe.

Biology question- how blood flows through the heart? As the left ventricle fills with blood, it contracts. This event is called ventricular systole. The aortic valve located between the left ventricle and aorta opens and closes quickly. This allows blood to flow into the aorta. The aorta is the main artery that carries blood from your heart to the rest of your body.xygen-rich blood returns from the lungs to your heart's left atrium through the pulmonary veins. As your heart's left atrium fills with blood, it contracts. This event is called atrial systole. The mitral valve located between the left atrium and left ventricle opens and closes quickly.

Ventricular system The ventricular system is a set of four interconnected cavities in the brain, where the cerebrospinal fluid is produced. Within each ventricle is a region of choroid plexus, a network of ependymal cells involved in the production of CSF. The ventricular system is continuous with the central canal of the spinal cord allowing for the flow of CSF to circulate. All of the ventricular system and the central canal of the spinal cord are lined with ependyma, a specialised form of epithelium.

How does cerebrospinal fluid circulate in the central nervous system? up vote 27 down vote favorite. 2. Cerebrospinal fluid (CSF) is produced in the choroid plexus of the lateral ventricles and in the 4th ventricle of the brain. CSF then circulates through the ventricles of the brain and the subarachnoid space of the meninges. CSF is returned to the venous system via the arachnoid granulations connecting the subrachnoid space with the superior sagittal sinus at the superior portion of the neurocranium.

- The chambers are known as atria and ventricles. Each side of the heart is composed of one atrium and one ventricle. The atria are the receiving chambers of the heart, receiving blood flowing back to the heart. The ventricles are the chambers of the heart that pump the blood out of the heart. The valves of the heart are located within the chambers of the heart and are critical to the proper flow of blood through the heart.

Lateral ventricles Lateral ventricles. The right and left lateral ventricles are structures within the brain that contain cerebrospinal fluid, a clear, watery fluid that provides cushioning for the brain while also helping to circulate nutrients and remove waste.he separate sections of the ventricular system are connected through small holes known as foramina. The lateral and third ventricles connect through the right and left interventricular foramina, while the third and fourth ventricles connect through a foramen known as the cerebral aqueduct.

- The Right ventricle feeds the Pulmonary artery through the pulmonary valve. There is no connection between them ap…art from, of course, that the blood flows out of the right ventricle through the pulmonary system (the lungs) and back via the pulmonary veins into the left atrium and then the left ventricle. The 2 heart pumps (ventricles) are in series, not in parallel.
