In a developing human, the first organ to form is thea. heart.b. brain.c. notochord.d. liver.
Hearts of mammals are described to have double pump structure. Which choice explains the functional and structural basis for the said description?
A. Blood enters the atrium and pumped into ventricle.
B. Blood pressure alternates between systolic and diastolic at all times.
C. Atrium provide 1 pump, ventricle provides 2nd pump.
D. Heart pumps blood simultaneously in systemic and pulmonary circuit.
In some reptiles, the two layers of dura mater fuse together in the brain. What is a likely consequence of this finding?
Group of answer choices
a. Because the two layers are fused, it will form a stronger blood-brain barrier.
b. Arteries are not able to pass through the two layers, so they must be rerouted around the dura mater.
c. With no space between layers, blood cannot be collected here for return to the venous system.
d. There will be increased damage to the tissue compared to mammals because in mammals, serous fluid between the layers reduces friction.
