What collects blood from the lungs?
Blood that has perfused the lungs and is now oxygenated collects into the pulmonary veins to travel back to the heart. Once reaching the heart, oxygenated blood from the lungs enters the left atrium. The left atrium collects blood from the lungs
How does blood travel to the muscle?
Blood moves from the heart. The heart is a pump and it moves the blood to the lungs where it picks up oxygen. The blood carries oxygen by way of large arteries into smaller arteries, into even smaller arterioles, into capillary beds. At this point oxygen is lost into tissues (like muscles). The blood is now low on oxygen and must pick up more in the lungs. It also has to deliver carbon dioxide to the lungs. Back to the capillary bed, into very small venules and then larger veins and larger veins and even larger veins to the heart. Blood moves into the lungs and drops off carbon dioxide and picks up another load of oxygen and back down and around again. The Circulatory System with the heart as a pump.
Which of the three major parts of the circulatory system can now be replaced by surgery?
The heart, individual heart valves, and blood vessels can be replaced by surgery.
What does the pulmonary circuit Carry blood to?
The pulmonary circuit carries deoxygenated blood from the heart to the lungs. In the lungs, carbon dioxide is exchanged for oxygen, and the now oxygenated blood returns to the heart. This process is essential for replenishing the blood's oxygen levels and removing carbon dioxide, a waste product of metabolism.
What carry the purplish or blue blood back to the heart to get more oxygen?
Veins carry the blood back to the heart and lungs for more oxygen. then the arteries carry the blood that now has oxygen it it to the rest of the body.
How will you describe the blood flow and gas exchange within the heart?
Blood flow within the heart follows a specific pathway: deoxygenated blood returns from the body to the right atrium, moves into the right ventricle, and is pumped to the lungs via the pulmonary arteries for gas exchange. In the lungs, carbon dioxide is released, and oxygen is absorbed into the blood. The now oxygenated blood returns to the left atrium, flows into the left ventricle, and is then pumped out to the body through the aorta. This continuous cycle ensures that oxygen-rich blood is delivered to tissues while facilitating the removal of carbon dioxide.
What is the function of vein?
Veins are the blood vessels responsible for returning blood to the heart. They carry deoxygenated blood (with the exception of the pulmonary vein) back to the heart whence it goes to the lungs to be re-oxygenated.
What supplies oxygen and eliminates carbon dioxide from the blood stream?
Lungs and Lungs. Blood that contains carbon dioxide means it is lacking oxygen, and the carbon dioxide was put into the blood as a waste product by all the other organs. The blood then reaches the lungs and exchanges the carbon dioxide for oxygen. The now oxygen-rich blood is transported to the heart where it is pumped throughout the body, and the carbon dioxide is exhaled from the lungs.
How do the heart and lungs work?
When we breathe in our lungs fill with oxygen rich air. Membranes in the lungs exchange the oxygen from the air with carbon dioxide in the blood. Then we breathe out the spent air to inhale fresh. The blood, now replenished with oxygen, is pumped by the heart through the arteries to all cells in the body where the oxygen is exchanged with the cells for carbon dioxide and returned through the veins to the lungs.
What is the process of blood starting at the superior-and inferior of the vena cava and the flow of pulmonary bloods and veins?
Blood flow begins when deoxygenated blood from the body returns to the heart through the superior and inferior vena cava, entering the right atrium. From there, it moves into the right ventricle, which pumps it through the pulmonary arteries to the lungs for oxygenation. In the lungs, carbon dioxide is expelled, and oxygen is absorbed. The now oxygen-rich blood returns to the heart via the pulmonary veins, entering the left atrium, and subsequently flows into the left ventricle to be distributed throughout the body.
What happens if the ductus arteriosus does not fully close after birth?
The infant will have abnormal blood flow between the aorta and pulmonary artery (those are the two major blood vessels in the heart). The ductus arteriosus is not needed after birth, since the lungs now fill with air (before birth, the pulmonary artery supplied blood to the lungs and aorta to be sent to the rest of the body).
How does the blood on the right side of the heart differ from the one on the left heart?
On the right side of the heart there is deoxygenated blood which has already been pumped round the body and is now returning to the heart. On the left side of the heart there is oxygenated blood which has just come from the lungs and is about to be pumped round the body Hope this is useful can't quite renember the names and technical words.. sorry...
