Question

1. which types of connective tissue belong in loose connective tissue? a. areolar, reticular, adipose b. reticular, elastic, adipose c. regular, elastic, irregular d. regular, irregular, reticular e. areolar, adipose, elastic 22. what is the difference between loose and dense connective tissue proper? a. dense has many spaces in the matrix, loose has few spaces in the matrix b. loose has many spaces in the matrix, dense has few spaces in the matrix 23. which the most common type of connective tissue in the entire body? a. regular dense ct b. reticular ct c. irregular dense ct d. areolar ct 24. plasma is a. the liquid matrix within all types of connective tissue b. the liquid matrix of blood c. the cellular portion of blood d. the liquid contained within bone where blood cells are produced 25. which type of blood cell transports oxygen and co2? a. leukocyte b. thrombrocyte c. erythrocyte d. chondroblast e. osteocyte 26. which is not a function of bone? a. support b. protection c. store calcium d. fight infection e. produce blood cells 27. which does not describe the matrix of bone? a. rigid b. abundant in collagen fibers c. abundant in elastic fibers d. abundant in calcium salts

Explanation:

1. Areolar, adipose, and reticular tissues are types of loose connective tissue.
2. Loose connective tissue has many spaces in the matrix, while dense connective tissue has few spaces.
3. Areolar connective tissue is the most common type in the body.
4. Plasma is the liquid matrix of blood.
5. Erythrocytes (red - blood cells) transport oxygen and CO₂. Among the options, erythrocyte is not listed, but it is the correct cell type.
6. Bone provides support, protection, stores calcium, and produces blood cells. Fighting infection is not a function of bone.
7. The matrix of bone is rigid, abundant in collagen fibers and calcium salts, but not abundant in elastic fibers.

Answer:

1. a. Areolar, reticular, adipose
2. b. Loose has many spaces in the matrix, dense has few spaces in the matrix
3. d. Areolar CT
4. b. The liquid matrix of blood
5. c. Erythrocyte (not in options but correct type)
6. d. Fight infection
7. c. Abundant in elastic fibers
