Introduction to Anatomy and Physiology Lesson 6.1 Study Questions Questions
Question 1 of 5
Bones are primarily composed of:
Correct Answer: D
Rationale: Bones blend calcium for rigidity and collagen for flexibility, forming a durable framework. Unlike cartilage or muscle, this composition supports and protects. Clinicians rely on it for fracture care, understanding its mineral-organic balance ensures skeletal strength and resilience throughout life.
Question 2 of 5
What is the name for the process by which cells break down food molecules to release energy?
Correct Answer: A
Rationale: Respiration breaks down nutrients in cells to release energy, powering all functions. Unlike replication or division, it's the metabolic engine. Nurses address its disruptions like in COPD ensuring energy production sustains life's demands.
Question 3 of 5
What is the name for the process by which cells reproduce to create new cells for growth and repair?
Correct Answer: C
Rationale: Mitosis duplicates cells for growth and repair, maintaining tissue integrity. Unlike meiosis's reproductive role, it's for renewal. Nurses leverage this in wound healing, ensuring cell division restores function and structure effectively.
Question 4 of 5
The process by which an egg cell and a sperm cell fuse to form a zygote is known as:
Correct Answer: C
Rationale: Fertilization unites egg and sperm into a zygote, launching development. Unlike division or diffusion, it's the reproductive spark. Clinicians monitor this in fertility, ensuring successful conception initiates life's cellular journey.
Question 5 of 5
What is the name of the process by which blood cells are formed?
Correct Answer: A
Rationale: Hematopoiesis crafts blood cells in bone marrow, sustaining oxygen transport and immunity. Unlike clotting or breakdown, it's creation. Clinicians track it like in anemia ensuring blood supply meets bodily needs.
