Example Question #11 : Connective Tissue
Which of the following is true of connective tissue?
It does not contain any blood vessels
Cells are tightly packed together
None of these
It is responsible for producing many hormones
Cells are separated by a large amount of extracellular material
Cells are separated by a large amount of extracellular material
Connective tissue is mostly extracellular material, with cells scattered sparsely throughout. One of the main components of the extracellular material involved in most connective tissue is collagen, a fibrous protein that plays a structural role.
Example Question #3 : Understanding Properties Of Connective Tissue
Which of the following is a type of connective tissue cell?
White blood cell
All of these
Adipocyte
Fibroblast
Plasma cell
All of these
Most connective tissue cells are fibroblasts (fiber-producing cells), which secrete the proteins that comprise the extracellular matrix. All blood cells are considered connective tissue, including white blood cells and plasma cells (mature B-lymphocytes). Adipocytes (fat cells) are responsible for connecting and surrounding body organs, and providing structural support, as well as storing energy for the body.
Example Question #12 : Connective Tissue
Which of the following is not a type of blood cell?
Pinocyte
Erythrocyte
Thrombocyte
Neutrophil
Leukocyte
Pinocyte
Blood cells, also called hematocytes, fall into three general categories: red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Erythrocytes primarily carry oxygen and collect carbon dioxide through hemoglobin. Leukocytes are involved in the immune system, defending the body against infections and foreign materials. One type of leukocyte is a neutrophil. Thrombocytes are very small cell fragments that are involved in hemostasis (stopping bleeding) and the formation of blood clots.
Pinocytes do not exist. However there is a mechanism called pinocytosis by which cells ingest extracellular fluid and its contents.
