How does the blood pumped from the heart to the rest of the body and back again?
The heart sends deoxygenated blood to the lungs, via the pulmonary arteries - thus this system is called the pulmonary circuit De-oxygenated blood flows from right ventricle of heart to lungs through two pulmonary arteries for oxygenation. After oxygenation the blood now travels through the pulmonary veins to left auricle of heart. Two pulmonary veins from each lung reach the heart making a total of four pulmonary veins. This circulation of blood to and from lungs is called pulmonary circulation. The pulmonary vein is thus the only vein which carries oxygenated blood and pulmonary artery in the same way the only artery to carry deoxygenated blood.
What protects your brain and your heart and lungs?
The breastbone (sternum) and the ribs are connected by cartilage to form the "thoracic cage" that covers the heart and lungs. It is not unusual for ribs to be fractured when using exterior compression on the heart, as is done in CPR.
How does positive feedback mechanism affect congestive heart failure?
Congestive heart failure simplified: The lungs are a low-pressure system. The right ventricle pumps blood to the lungs under little resistance within the lungs. If the lungs fill with enough fluid to increase the lung resistance to blood pumped from the right ventricle, and this resistance exceeds the ability of the right side of the heart to overcome this increased pressure, the heart will decrease its output of blood. The decrease in the heart’s output of blood causes less blood to flow to the kidneys and the kidneys expel less fluid in the urine. This causes more fluid to build up in the blood and in the lungs. This increased fluid in the lungs exacerbates the pressure backup cycle. This cycle of one system leading to an increase in another in life systems is often a death cycle—scientifically referred to as a positive feedback cycle. If something is not done to bring homeostasis back, the system will fail...heart failure. The first line of treatment is often a diuretic to help the kidneys expel excess fluid.
How do the arteries of the pulmonary circulation differ structurally from the systemic arteries?
The pulmonary arteries have walls that are more thin than the systemic arteries. This is because the pulmonary arteries do not serve the metabolic needs of the body tissues, but only the lungs. The function of these arteries is to bring blood into close contact with the alveoli of the lungs.
How is the human heart related to te circulatory system?
the heart is related to the circulatory system because the circulatory and the heart sirculate blood through the veins and the whole entire body
Which organ transports oxygen to other body parts?
It is done by veins and arteries (known as blood capilleries) vien take impure blood from different body parts to heart which then carry to lungs for purification and from lungs this pure blood carry again to hear which is pumped by arteries to the different body parts. So blood capelleries, and heart help in transporting the blood.
Why does blood go from the right ventricle to the lungs?
The blood coming from your body tissues is low in oxygen (O2) and needs to be pumped to your lungs to reduce their content of carbon dioxide and pick up more oxygen. Once it has done that, it returns to the heart to be pumped throughout your body.

Why does blood from the right ventricle go to the lungs?
Yes. Then, the artery forms to a aertiole, then to a capillary. After that the process continues, the capillary will turn into a venule then to the vein. If you didn't arteries travel from the heart and veins carry blood to the heart. So then the vein will bring the blood to the left atrium... bicuspid valve... left ventricle... aortic valve... aorta

Where does blood travel to and from pulmonary circulation?
after it is done with the pulmonary circulation it goes directly to the lungs
Where does the blood go after the exchange of carbon dioxide and oxygen?
Blood flows from the venous system to the right atrium of the heart to the right ventricle of the heart through the pulmonary arteries, to the lungs (where the CO2/O2 exchange is done) through the pulmonary veins, and back to the left atrium of the heart, to the left ventricle of the heart, and out through the aorta and to the rest of the body. It then returns through the veins and repeats the process.

Where does blood travel to and from during pulmonary circulation?
after it is done with the pulmonary circulation it goes directly to the lungs
What is done to a boy during a physical exam?
A boy, who is having a physical exam, will have his blood pressure taken. They will also check the heart rate, listen to the lungs and heart, check respiration, and temperature. They will look at the overall appearance including the ears, lymph nodes, and abdomen.
Why does blood pressure decrease after exercising?
Because when you exercise, your heart works harder to get blood to the muscles and when your're done, there is no need for the heart to beat fast.
