De-oxygenated blood enters the right atrium from the vena cava and then passes through the tricuspid valve into the right ventricle. It is then sqeezed/pumped through the right semi lunar valve into right pulmonary artery which transports blood to the lungs. Oxygenated blood returns to the heart via pulmonary veins and enters the left atrium, passes through the bicuspid valve to enter the left ventricle which contracts, sqeezing/pumping the oxygenated blood through the left semi lunar valve into the aorta from where it is transported to all the body's cells.

Do viens carry the blood back to the heart?
Yes, the veins are responsible for carrying blood from the body and back to the hearth, but you should be careful not to get confused by the pulmonary artery and the pulmonary vein!! the pulmonary artery carries De-oxygenated blood from the hearth to the lungs while pulmonary veins carry oxygenated blood from the lungs back to the hearth.
What is the function of the hearth?
The heart is a muscle that functions as the bodies circulatory pump. It pumps blood through veins and deliverers it to the lungs.
What phase of the heart cycle is the blood pumped out of the heart?
it is pumped out of the lungs
What happens after blood returns to the lungs?
it carrys on the same cycle over and over again hope dis helps
What is a pulmonary cycle?
Oxygenated blood leaving the lungs through the Pulmonary Veins, which return it to the left side of the heart thus completing the cycle
How is oxygendistrubuted to the different areas of the body?
Oxygen is inhaled to the lungs were a cleaning process occurs. The oxygen is mixed into the blood stream and this is carried by the blood flow around the body. Designated blood returns to the lungs for the cycle to restart
Function of the crdiaac tissues?
Cardiac tissue is the heart muscle and its function is to pump blood between the heart-lungs cycle and the heart-body cycle.
Why do humans need ribs?
To protect the internal organs (such as the hearth and lungs) from damage.
Where does the blood with no oxygen go?
Back to the lungs to pick up more oxygen so it can continue in a cycle to fuel the body.
What gas does the body need for the heart and lungs?
Heart has two sides (4chambers) separated by a septum.One side it collects the impure blood ie from all the parts of our body and pumps it to lungs. At lungs through alveoli the co2 diffuses out and oxygen enters the blood. this pure blood (oxygenated blood) enters the other side of heart from where it is pumped to all body parts AND cycle continues.
What do the blood cells do in the cardiovascular system?
Provide oxygen to the entire body, from the brain to the pinky toe. Blood is circulated via the Pulmonary Artery from the heart to the lungs, and from the lungs (where oxygen is absorbed by the red blood cells) to the rest of the body. After the oxygen has been dispersed, the blood cells begin the cycle anew.
How does blood entering the lungs differ from blood leaving the lungs?
The blood leaving the lungs is loaded with oxygen, while blood entering the lungs is about to get oxygen from the respiratory system.
