The patient is in progressive stage of shock.
What are the stages of shock?
When reduced blood flow (perfusion) is first noticed during Stage I shock, a number of processes are engaged to maintain/restore perfusion. This activation causes the blood arteries throughout the body to narrow (vasoconstriction), the heart to beat more quickly (tachycardia), breathing to speed up (tachypnea), and the kidneys to work harder to keep fluid in the circulatory system. On the AVPU scale, the patient is most certainly awake but may have altered mental status, such as bewilderment, irritation, or lethargy.
These compensatory techniques start to fall short in shock Stage II. The patient's symptoms demonstrate that the body's processes are no longer able to increase perfusion. On the AVPU scale, the patient becomes V, P, or U due to oxygen deprivation in the brain. Blood pressure may be near or below normal yet heart rate, breathing rate, and blood pressure are all still over average.
The duration of the poor perfusion starts to permanently damage the body's organs and tissues in Stage III of shock. The kidneys typically fully shut down, and the heart's performance continues to deteriorate. Heart and respiratory rates are significantly higher than average before collapsing to low rates that are not compatible with life. Additionally, the patient's blood pressure is dangerously low. The body's organs and tissues all contain damaged and dying cells. The patient's death is the eventual result of Stage III shock.

Answer:
Umbilical cord
Explanation:
Allantois is a hollow sac like structure. Its primary role is to eliminate liquid waste from the fetus and help in exchange of gases. Amniote is the group of organisms which contain allantois, amnion and chorion. Reptiles, birds and mammals are part of this group.
In mammals, allantois develops into umbilical cord. Umbilical cord is present between the fetus and the placenta. Human umbilical cord has two arteries and one vein. The vein brings nutrient rich, oxygenated blood from the placenta to fetus. The arteries brings back nutrient depleted, deoxygenated blood to placenta.
