BIOD 151 – Lab 8 Exam: Histology of Connective
Tissue (Portage Learning) | 2025/2026 Verified
Questions with Correct Answers | Graded A+
The BIOD 151 Lab 8 Exam focuses on the histology of connective tissue, emphasizing tissue
classification, structural features, and functions. This updated 2025/2026 edition provides 40
verified, exam-style questions with correct answers, ensuring mastery of connective tissue
identification and application in anatomy/physiology contexts.
Overview
This resource enables learners to distinguish connective tissue types, recognize structural
features (fibers, ground substance, cells), and apply knowledge to physiological functions. Rated
A+ for accuracy, it aligns with Portage Learning BIOD 151 objectives and the exam’s format of
40 multiple-choice and identification questions.
Answer Format
Correct answers are highlighted in bold green. Each question includes a rationale to reinforce
learning and explain histological principles.
Exam Questions
Connective Tissue Classification
1. What is the primary function of connective tissue?
A. Contraction
B. Support and structure
C. Secretion
D. Absorption
Rationale: Connective tissue provides structural support, binding, and anchoring,
unlike muscle (contraction) or epithelial (secretion/absorption) tissues.
2. Which connective tissue has a dense matrix with tightly packed collagen
fibers?
A. Adipose tissue
B. Dense regular connective tissue
C. Loose areolar tissue
, D. Cartilage
Rationale: Dense regular connective tissue, found in tendons, has parallel collagen
fibers for strength.
3. What is the most abundant fiber in connective tissue?
A. Elastic fibers
B. Collagen fibers
C. Reticular fibers
D. Fibronectin fibers
Rationale: Collagen fibers provide tensile strength and are the most common in
connective tissues.
4. Which connective tissue stores fat?
A. Cartilage
B. Adipose tissue
C. Blood
D. Dense irregular tissue
Rationale: Adipose tissue, composed of adipocytes, stores fat for energy and insulation.
5. What characterizes loose connective tissue?
A. Rigid matrix
B. Abundant ground substance
C. Tightly packed fibers
D. No cells
Rationale: Loose connective tissue, like areolar, has abundant ground substance and
fewer fibers.
6. Which connective tissue forms a supportive framework for lymphoid
organs?
A. Dense regular
B. Reticular connective tissue
C. Adipose tissue
D. Elastic cartilage
Rationale: Reticular fibers form a network in organs like the spleen and lymph nodes.
7. What is a feature of dense irregular connective tissue?
A. Parallel collagen fibers
B. Randomly arranged collagen fibers
C. No fibers
D. Elastic fibers only
Rationale: Dense irregular tissue, as in the dermis, has collagen fibers arranged in
multiple directions.
8. Which connective tissue is considered a fluid connective tissue?
A. Cartilage
