Sustained elevated arterial pressure of 140/90 mm Hg indicates which condition?

How are gases and nutrients exchanged via the capillaries?

Fluid movement at capillary beds depends on the difference between the two pressures- what forces fluid and solutes out of capillaries?

Fluid movement at capillary beds depends on the difference between the two pressures- what pressure draws fluid into capillaries?

Which end of the capillary bed has higher blood pressure vs osmotic pressure?

Which end of the capillary bed has lower blood pressure vs osmotic pressure?

During which week of pregnancy does the fetus develop a 4 chambered heart that is capable of acting as a double pump?

During fetal development, the umbilical cord via one _______ carries nutrient and oxygen rich blood to the fetus.

During fetal development, two of these carry wastes and carbon dioxide-rich blood from the fetus to the placenta.

What are present in a fetus that bypass the lungs and liver?

When the fetus is still developing, blood flow bypasses the liver through the ductus venous and enters the inferior vena cava which is in which chamber?

In fetal development, blood flow bypasses the lungs, and the blood upon entering the right atrium is shunted directly into the __________ through foramen ovule (which becomes fossa ovals after birth)
