In the human circulatory system, deoxygenated (low-oxygen) blood returns to the heart from various parts of the body through the veins. This deoxygenated blood is then pumped into the right atrium of the heart. From the right atrium, it is pushed into the right ventricle, and then the right ventricle contracts, sending this deoxygenated blood to the lungs through the pulmonary artery.
In the lungs, this deoxygenated blood receives fresh oxygen and gets rid of carbon dioxide through the process of respiration. Once oxygenated in the lungs, this blood is returned to the left atrium of the heart through the pulmonary veins. From the left atrium, it enters the left ventricle, and then the left ventricle contracts to pump this oxygenated blood out into the body through the aorta and various arteries, delivering oxygen to the body's tissues and organs.
The specific details of how this process is taught or explained at Brain Discovery Global School, or any other school, may vary, but the general flow of blood in the circulatory system remains consistent in human Biology.

Which organ's blood flow pattern results in low oxygen levels causing vasoconstriction and high oxygen levels causing vasodilation?
lungs
How can the oxygen you bring in to your body get into your circulatory system?
your lungs have structures called alveoli. The alveoli are surrounded by capillary beds which carry blood. The oxygen enters the alveoli when you inhale. The oxygen then diffuses from high concentration in your alveoli to low concentration the blood in the capillaries surrounding the alveoli.
Why do you need more nitrogen than oxygen?
Nitrogen is an inert gas it maintains a proper ratio of oxygen requred by living organisms if oxygen is in higher ratio the respiratory organs become oxidized and more oxygen in blood is harmful as low concentration of oxygen.
Is oxygen's reactivity high or low?
Oxygen stays as diatomic molecules in the atmosphere. These 2 oxygen atoms are bond with a double bond. So reactivity of oxygen is low.
How do you explain how oxygen gets into your blood?
We should first start at the beginning. As you know, you breathe oxygen in when you contract your diaphragm and air fills your lungs. The walls of your lungs are filled with capillaries (tiny blood vessels) that look kind of like feathers. If you were to stretch out the entire surface area of the capillaries in your lungs, it would be about equal to the size of a tennis court! So, in the capillaries flows your de-oxygenated blood. It has been on a complete cycle through your body, and is now low on O2. When the erythrocytes (red blood cells) enter the capillaries, the oxygen gets chemically stuck to them. It attaches to a large protein called hemoglobin, a 4 piece protein with a single iron atom at the center. (this explains why an iron deficiency can lead to anemia, or a low red blood cell count) Each red blood cell contains as many, many hemoglobin molecules. The oxygen is at a HIGH concentration in your lungs, and so flows into the LOW concentration in the blood. As the laws of nature would predict, as the red blood cells move into areas of lower oxygen concentration, the oxygen leaves the hemoglobin and enters its new tissue.
What side of the heart receives blood that is low in oxygen?
right
What is the name of the chamber that receives low-oxygen blood back to the heart?
Right Atrium
Chamber containing deoxygenated blood?
which of the following structures receives deoxygenated blood from the body via the vena cavae
Which heart chamber receives oxygen poor blood from all tissues except the lungs?
The right side of the heart (right atrium and right ventricle) receives blood low on O2.
What type of blood has low oxygen and high carbon dioxide?
Deoxygenated blood is low in oxygen and high in carbon dioxide.
What if oxygen-rich blood mixes with your oxygen-poor blood?
the quality of our blood that rich with oxygen will become low
One of two thin-walled chambers that receieve blood into the heart from the veins?
Atrium
Low oxygen in blood?
hypoxemia
The vein that bring blood low in oxygen from the head and upper limbs is called?
Left Atrium. Chamber that receives oxygenated blood from the pulmonary veins and pumps it into systemic circulation. Superior Vena Cava. Carries (drains) blood from the head, neck, and upper limbs and empties in the right atrium.
What blood vessel normally transport blood that is low in oxygen?
Low oxygen/de-oxygenated blood is carried by:all the veins (except the pulmonary vein)the pulmonary artery.
What kind of blood does lungs have?
Same blood as everywhere else. The difference is the gases in the blood: it enters the lungs low on oxygen and high in CO2, it leaves high in oxygen and low in CO2.
A decrease in the blood's ability to transport oxygen is called what?
The correct name for low levels of oxygen in the blood is hypoxaemia. Low levels of oxygen in the body tissues is called hypoxia
