Woven bone Select one: a. has its collagen fibers randomly oriented. b. has a porous appearance. c. is organized into thin sheet

kogti [31]

Answer: A . Has its collagen fibers randomly orientated.

Explanation:

In the microscopic anatomy of the bone, an osteon (basic microscope unit of the bone) can be arranged into two categories; woven bone or lamellar bone.

As the name suggests woven bone is characterized by the random orientation of the collagen fibers . These collagen fibers haphazardly form to give the visual appearance of an intertwined (woven) network of collagen fibers.

Due to the randomness of the collagen fibers orientation woven bone is thus mechanically weaker than lamellar bone. Woven bone is formed/produced when osteoblasts produce osteoids rapidly within the bone matrix thus woven bone has the ability to form quickly as needed.

Woven bone is thus immature bone or pathologic bone with no stress orientation, it has a high percentage of osteocytes per unit volume and a high rate of turnover.

Answer:

The increase in the amount of carbon dioxide in in blood will lead to respiratory acidosis

Explanation:

Carbon dioxide in its normal level between 38 to 42 mm Hg plays vital roles in the human body like regulating the PH of the human blood, breathing regulation and other things. If the amount of carbon dioxide is high more than the range level, it will cause what is called respiratory acidosis.

Respiratory acidosis is a situation in cause by decrease in ventilation i.e Oxygen level leading to increase in carbon dioxide and drop in PH level of the blood.
