Oxygenated and Deoxygenated Blood...?

Question

What would the effect be if Oxygenated and Deoxygenated blood would mix? Would this just become semi-oxygenated blood or would it have a bad effect?

Answer 1

If the oxygenated blood and deoxygenated blood mixed, then blood would circulate through the body without being fully oxygenated. Also the deoxygenated blood is supposed to take that trip through the lungs to give up the carbon dioxide. It's not going to be a good idea to bypass that step.

Answer 2

Oxygenated And Deoxygenated Blood

Answer 3

well, many animals still have an incomplete interventricular septum, allowing this to occur. Reptiles (excluding crocidilians) and amphibians have chambered hearts which allow for deoxygenated blood to mix with the oxygenated blood. This would cause the blood to become semi-oxygenated as you asked, which would affect the efficiency of the delivery of O2 to the tissues of the body. The effect would not be bad considering it would not result in death, but activity by the animal would be decreased. Mammals have four chambered hearts because of the increased size and locomotion which requires a more efficient delivery system.
I hope that answers your question!

Answer 4

You're correct, mixing oxygenated and oxygenated blood would have the effect of "semi-oxygenated blood". To be more specific, some of the hemoglobin-bound oxygen would dissociate and bind to the non-oxygenated hemoglobin (in the non-oxygenated red blood cells). Thus, an hemoglobin saturation equilibrium would be reach, as each red blood cell in the mixed blood would now have (approximately) the same oxygen saturation.

This might be bad, for example, in the heart. If oxygenated blood is mixing with oxygenated blood in the heart (such as a child with a ventricular septal defect aka "hole in the heart"), then the blood that should be fully oxygenated and sent to the tissues (via systemic circulation) for oxygen delivery, would no carry less than optimal concentrations of oxygen. The body, therefore, would get less oxygen that normal. This could lead to several symptoms, including: fatigue, shortness of breath, respiratory acidosis.

Answer 5

That has actually happened, and does happen. It causes low blood oxygen, high blood pressure, weakness, and even death. It happens sometimes when there is a hole between the two sides of the heart. It can also happen in genetic defects where certain arteries/veins are connected wrong. It doesn't cause like an explosive chemical reaction, but it can be very dangerous...

Answer 6

Deoxygenated blood has no oxygen in it so it is blue. This is why when someone is choking they turn blue. Oxygenated blood is red.

Answer 7

The blood system of vertebrates is a closed system, i.e. the blood vessels are not open -ended. In the organs the arteries divide to form arterioles (small arteries) which in turn divide to form numerous capillaries. The capillaries unite to form larger vessels, called the venules (small veins). The venules leave the tissues and join with other venules to form veins. Veins leave the organs and eventually join the venae cavae. It is thus clear that the arterial and venous blood link up by means of capillaries in the tissues.

In this section we will discuss the main circulatory system.

Pulmonary Circulation.

The pulmonary artery arises from the right ventricle and tranports deoxygenated blood (oxygen-poor) to the lungs, where the blood becomes oxygenated again. The four pulmonary veins return the oxygenated blood (oxygen-rich) to the left atrium of the heart. The pulmonary circulation is also referred to as the lesser circulation. The summary of the pulmonary circulation is thus:

Right Ventricle - pulmonary artery - lungs - pulmonary veins - left atrium - left ventricle.

Answer 8

semi-oxygenated. Many reptiles, eg crocoldiles and turtles, do this anyway as a means of conserving heat. Bad if oxygenation drops too low!

Answer 9

well it wud surely not become semi oxygenated...oxygenated blood leaves via aorta n deoxy blood with co2 comes to lungs for being purified.....in some case if it gets mixed it wud recirculate and be purified thereof.

Answer 10

It will give you a bad effect, lack of oxygen and may affect your nervous and reporductory system.
