Multiple Choice

How can a fractured diaphysis release fat globules into the bloodstream?

By causing muscle tissue to break down into fatty acids

By stimulating the liver to produce more lipids

By rupturing the bone marrow, allowing fat to enter blood vessels

By increasing calcium absorption in the intestines

Verified step by step guidance

Understand the anatomy of a long bone: The diaphysis is the shaft of a long bone, and it contains the medullary cavity, which houses yellow bone marrow. Yellow bone marrow is rich in fat cells (adipocytes).

Recognize the physiological impact of a fracture: When the diaphysis is fractured, the structural integrity of the bone is compromised, potentially rupturing the medullary cavity and exposing the yellow bone marrow.

Learn how fat globules enter the bloodstream: The rupture of the medullary cavity can allow fat from the yellow bone marrow to escape into nearby blood vessels, leading to the release of fat globules into the circulatory system.

Understand the consequences of fat embolism: Fat globules in the bloodstream can lead to a condition called fat embolism syndrome (FES), which may obstruct blood flow and cause complications in organs such as the lungs, brain, or skin.

Clarify why other options are incorrect: Muscle tissue breakdown into fatty acids, liver stimulation to produce lipids, or increased calcium absorption in the intestines are unrelated to the mechanism of fat globule release following a diaphysis fracture.
