Which organ's blood flow pattern results in low oxygen levels causing vasoconstriction and high oxygen levels causing vasodilation?
lungs
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.
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.
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
Low oxygen in blood?
hypoxemia
In a mammal blood with low oxygen content enters the of the heart?
The blood with high oxygen content enter the heart in left atrium through right and left pulmonary veins, combined together.
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
What makes the concentration of oxygen low in the alveolus?
Oxygen diffuses into the blood capillary
Cause for low blood oxygen?
Low blood oxygen has many causes, often respiratory disorders, and can cause tissue hypoxia as the blood is not supplying enough oxygen to the body. Hypoxemia is the medical term used to refer to this condition.
Where does the heart pump blood low in oxygen and high in carbon dioxide?
The heart pumps blood low in oxygen and high in carbon dioxide to the lungs, where blood releases carbon dioxide and picks up oxygen.
Lack of oxygen in a person's blood?
The term for a low amount of oxygen in blood is called cyanosis. It refers to the bluish color of some body tissues, like the lips, because cyan is the name of a shade of the color blue. Or it can be called anemia if it is due to the low number of healthy red blood cells that carry oxygen.
Where does oxygen pass into your blood?
Oxygen diffuses into the blood in the lungs and binds to the hemoglobin since the oxygen concentration is high and the carbon dioxide concentration is low. The blood is pumped to the body. The hemoglobin releases the oxygen to the tissues because here, the concentration of oxygen is low and that of carbon dioxide is high.
