INSTANT PDF DOWNLOAD – This comprehensive study guide for the BIOD 151 Final Exam at Portage Learning (Latest 2026/2027 Update) features verified exam questions with correct answers and detailed rationales covering all seven modules . This A+ Graded resource covers all key topics required for the cumulative final assessment at Geneva College / Portage Learning . Key Topics & Practice Questions Q1: What are the six levels of structural organization in the human body? Answer: Atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism. Rationale: The body is organized in a hierarchy from the simplest level (chemical) to the most complex (the whole organism). Each level builds upon the previous one . Q2: What system provides the necessary life function that protects our internal environment from our external environment? Answer: The integumentary system. Rationale: The integumentary system (skin, hair, nails) acts as a physical barrier protecting internal organs from mechanical damage, pathogens, UV radiation, and dehydration . Q3: List two organs contained in the abdominal cavity. Answer: The stomach, intestines, spleen, liver, gallbladder, pancreas, and kidneys. Rationale: The abdominal cavity extends from the diaphragm to the pelvic brim and houses most digestive organs, spleen, and kidneys . Q4: What is the primary purpose of cellular respiration? Answer: To produce ATP. Rationale: Cellular respiration is the complex process in which cells make adenosine triphosphate (ATP) by breaking down organic molecules, primarily glucose. ATP is the energy currency used to drive processes requiring energy . Q5: The frontal plane is also known as the: Answer: Coronal plane. Rationale: Both terms are used interchangeably in anatomy. This plane divides the body into anterior (ventral) and posterior (dorsal) portions . Q6: Is the elbow proximal or distal to the hand? Answer: Proximal. Rationale: Proximal means closer to the point of attachment or trunk; distal means farther away. The elbow is closer to the shoulder (attachment point) than the hand, so the elbow is proximal to the hand . Q7: What is tonicity? Answer: Tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a partially-permeable cell membrane. Rationale: Tonicity depends on the relative concentration of selective membrane-impermeable solutes across a cell membrane, which determines the direction and extent of osmotic flux . Q8: What are osteoblasts and osteoclasts? Answer: Osteoblasts are the cells responsible for the synthesis and mineralization of bone matrix. Osteoclasts are large, multinucleated cells responsible for the resorption of bone. Rationale: Bone tissue is constantly turned over by these two cell-mediated processes. Osteoblasts form new bone, while osteoclasts break down old bone tissue .
