Answer: Option A

Explanation:

The rectum is the final straight portion of the large intestine in humans and some other mammals, and the gut in others.

The adult human rectum is about 12 centimetres (4.7 in) long, and begins at the rectosigmoid junction, the end of the sigmoid colon, at the level of the third sacral vertebra or the sacral promontory depending upon what definition is used.

Its caliber is similar to that of the sigmoid colon at its commencement, but it is dilated near its termination, forming the rectal ampulla.

It terminates at the level of the anorectal ring (the level of the puborectalis sling) or the dentate line, again depending upon which definition is used.

In humans, the rectum is followed by the anal canal which is about 4 centimetres (1.6 in) long, before the gastrointestinal tract terminates at the anal verge. The word rectum comes from the Latin rectum intestinum, meaning straight intestine.

The Sun is a star. There are lots of stars, but the Sun is the closest one to Earth. It is the center of our solar system.

The Sun is a hot ball of glowing gases. It keeps our planet warm enough for living things to thrive. It gives us light so we can see.

Eight planets move around the Sun. We call that an orbit. The planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Lots of smaller worlds orbit the Sun. Pluto is a dwarf planet beyond Neptune. There are many asteroids and comets that go around the Sun, too.

Explanation:

Macrophages that reside in adult healthy tissues either derive from circulating monocytes or are established before birth and then maintained during adult life independently of monocytes. By contrast, most of the macrophages that accumulate at diseased sites typically derive from circulating monocytes.
