The correct answer is:
D
.Villi in the small intestine have thin-walled capillaries to make the absorption of nutrients more efficient.
Explanation:
The small intestines are well adjusted for absorbing nutrients during digestion by being very long, having villi and microvilli that enlarge surface area, using muscular contractions to move and mix food, and raising and housing digestive enzymes and bile that aid the breakdown of food. The inner surface of the small intestine is not flat but thrown into circular folds, which not only enhance surface area but aid in preparing the ingesta by acting as baffles. Villi: the mucosa makes multitudes of ridges which project into the lumen and are satisfied with epithelial cells.
Answer is number 1........
I will come back to this question tomorrow with the paragraph
12)
receptor cell bodies are found in the dorsal ganglia which is F
relay cell bodies are found in the grey matter which is G
effector neuron bodies are found in the grey matter which is G
so the answer is D
13)
J is the dorsal root of the spinal nerve and contains the axons of the sensitive cells
H is the anterior root of the spinal nerve and contains the axons of the motor cells
therefore the answer is C
14)
F is the dorsal ganglion
I is the spinal nerve
hence, the answer is B
15)
first they come through the spinal nerve which is (I), then they go through the dorsal root, which is (J) then the impulses go through the grey matter(G) , they go through the anterior root(H) and finally through I
the answer is A
