BIO 202L Rat Practical 2025/2026 | 70+ Q&A | Muscles, Organs, Circulation, Reproductive System

This detailed study guide provides 70+ clearly answered practical exam questions for the BIO 202L Rat Practical in the 2025/2026 academic year. It is designed to help students prepare for lab-based practicals focused on the anatomical structures and physiological functions of the rat — a standard model in biology and pre-health lab courses. The document thoroughly covers major systems and anatomical features, including: Muscular system: masseter, sternomastoid, biceps/triceps brachii, gluteus, gastrocnemius, spinodeltoid, latissimus dorsi Digestive and excretory systems: liver, stomach, pancreas, small intestine, cecum, colon, kidneys, ureters, bladder Cardiovascular and respiratory systems: heart chambers, aorta, vena cava, carotid arteries, pulmonary arteries, lungs, trachea Endocrine and immune system: thymus, hormonal regulation, spleen Reproductive system (male and female): testis, epididymis, prostate, seminal vesicle, penis, ovary, uterine horn, vagina Nervous and support structures: diaphragm, esophagus, external jugular veins, subclavian artery Each entry includes the anatomical term followed by a concise, exam-focused description of its function or location, making this document ideal for rapid review or in-depth lab practical prep. Relevant for: Students in Biology, Anatomy & Physiology, Zoology, Pre-Med, Veterinary, and Health Science Laboratory programs Courses including BIO 202L, Comparative Anatomy, Animal Physiology Labs, and Dissection Practicals Keywords: rat anatomy, rat dissection, BIO 202L practical, muscular system, circulatory system, digestive organs, respiratory structures, male reproductive, female reproductive, thymus, spleen, kidney, bladder, ureter, aorta, atria, femoral muscles, pre-med lab exam
