Answer:
Kupffer cells, also known as stellate macrophages due to their particular structure while viewed under a microscope, were first identified by scientist Karl Wilhelm von Kupffer, after whom the cells were named, in 1876.
These cells, whose origin is in the yolk sack during fetal development, later on move to the liver where they will stay and further differentiate into their mature versions.
These cells are part of the liver cells, and are found particularly on the walls of the sinusoids, where they perform their two most important tasks. First, these cells are part of the immune system, as they are essentially macrophages. However, their role is pretty unique, as they are responsible not just for phagocytosis of invading bacteria, and other pathogens, and initiating immune responses, but also, this cell plays a role in decomposing red blood cells who are dying, and taking up the hemoglobin from them to further break that into reusable globin, and the heme group, from which iron is further extracted to be re-used and also to create bilirrubin, a part of bile.
Finally, these cells have been found to be connected to hepatic cirrhosis, as in their process of detoxifying ethanol, they produce toxins that force the liver cells to produce collagen, and thus to become fibrous.

Explanation:
Answer:
The correct option is: b. False
Explanation:
The ductus venosus is one of the three shunts of the fetal circulatory system. It is responsible for providing highly oxygenated blood to the inferior vena cava, followed by the right atrium of the fetal heart. Therefore, the main role of this shunt is to bypass the non-functioning liver of the fetus.
Answer:
Benefits will be coordinated.
Explanation:
Since in the question, it is given that both husband and wife are insured under group health insurance plans and it is also under spouse coverage
Now if one of them incurred the expenses so the expenses which are to be incurred are to pay based on the benefits that are coordinated as if an individual covered in two or more plans so it is would be paid as benefits coordination and the same is to be considered in a couple.
The anterior fontanel is a diamond-shaped area where the frontal and parietal bones meet. It closes between 12 and 18 months of age. Vigorous crying may cause the fontanel to bulge, which is a normal finding. A nurse is performing an assessment on a postterm infant.
<h3>What is anterior fontanel?</h3>
- This is the junction where the 2 frontal and 2 parietal bones meet. The anterior fontanelle stays soft until about 18 months to 2 years of age. Doctors can consider if there is increased intracranial pressure by touching the anterior fontanelle.
- The fontanel can broaden in the first few months of life,18 and the median age of closure is 13.8 months. By three months of age, the anterior fontanel is secured in 1 percent of infants; by 12 months, it is closed in 38 percent; and by 24 months, it is closed in 96 percent.
- The fontanelle allows the skull to distort during birth to facilitate its passage through the birth canal and for expansion of the brain after birth. Skull at birth, showing frontal and occipital fonticuli. The anterior fontanelle normally closes between the periods of 12 and 18 months.
