BIO 202 Midterm Exam 2026/2027 | 120+ Questions & Answers | Endocrine, Blood, Cardiovascular, Immunity, Respiratory, Renal & Digestive Systems

This comprehensive BIO 202 Midterm Exam Compilation 2026/2027 contains 120+ multiple-choice questions with answers across 64 pages, providing focused preparation for students studying human biology, anatomy and physiology, or related biomedical sciences. The material begins with endocrine physiology and metabolism, including glycogenesis, steroid hormones, growth hormone, insulin, hormone receptors, FSH, paracrine signaling, adrenal hormones, PTH, estrogen, testosterone, aldosterone, and hypothalamic-pituitary regulation. It then progresses into blood physiology and hematology, including erythrocytes, leukocytes, hemoglobin, plasma proteins, erythropoiesis, coagulation, blood groups, transfusion compatibility, platelets, and humoral and cell-mediated immunity. Cardiovascular material covers cardiac anatomy and physiology, preload and afterload, venous return, blood pressure regulation, cardiovascular centers, coronary perfusion, vascular resistance, vasodilation, capillary structure, ventricular filling, the Frank-Starling mechanism, cardiac muscle, intercalated discs, and the cardiac cycle. The document specifically reminds students to review the Wiggers diagram, making integration of cardiac pressure, volume, valve, and electrical events an important review area. The immunity and lymphatic sections address nonspecific defenses, inflammation, fever, lymphatic tissues and organs, B cells, T cells, cytokines, phagocytosis, vaccination, antibody-mediated immunity, and lymphatic functions. Respiratory physiology receives extensive coverage, including respiratory anatomy, alveoli, pulmonary ventilation, gas exchange, partial pressures, Dalton’s and Henry’s laws, surfactant, lung volumes, anatomical dead space, respiratory control centers, central and peripheral chemoreceptors, carbon dioxide transport, the chloride shift, alveolar ventilation, and ventilation responses during exercise. The final pages also identify the hemoglobin dissociation curve as material students should specifically review. Renal physiology topics include glomerular filtration, nephron function, secretion and reabsorption, GFR regulation, renin, ADH, aldosterone, aquaporins, the juxtaglomerular apparatus, renal corpuscle, vasa recta, acid-base regulation, urine concentration, and glucose reabsorption. The digestive-system portion covers GI anatomy and epithelium, phases of digestion, CCK, secretin, intrinsic factor, Brunner’s glands, gastric regulation, pancreatic enzymes, liver functions, bile salts, carbohydrate and lipid digestion, and gastrointestinal motility.

A university name or external APA citation should therefore not be added as if it were documented in the source.
