Carbohydrates on the surface of leukocytes play an important role in responding to infection or inflammation. Place the following steps of the response in the correct orderA. Endothelial cells express selectins on their plasma membrane. B.Selectins bind to carbohydrates on the surface of leukocytes, causing them to stick. C.Leukocytes crawl out of vessel into adjacent tissue. D.Leukocytes roll along vessel walls. E.Cytokines are released at sites of infection or inflammation and stimulate endothelial cells of blood vessels.

The steps of the response in the correct order are:

E) Cytokines are released at sites of infection or inflammation and stimulate endothelial cells of blood vessels.

A) Endothelial cells express selectins on their plasma membrane.

B) Selectins bind to carbohydrates on the surface of leukocytes, causing them to stick.

D)Leukocytes roll along vessel walls

C)Leukocytes crawl out of vessel into adjacent tissue.

Explanation: Inflammation is defined as the reaction of vascularized living tissue to local injury ( trauma). Cell involved in inflammatory responses includes:

- leucocytes

- macrophages

-lymphocytes and

- vascular endothelial cells.

There are sequence of events that leads to leucocytes extravasation( that is, movement of leucocytes from blood vessels into tissue spaces) in response to inflammation. These includes the steps listed above in their correct order. I hope this helps.

answer: c

explanation:

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
