SFSU BIO 230 FINAL EXAM 2026 EXAM
QUESTIONS AND ANSWERS | 100%
PASS
Why is homeostasis important? - 🧠 ANSWER ✔✔to maintain a relatively
stable environment, within limits.
How does the body maintain homeostasis? - 🧠 ANSWER ✔✔through
cooperation of multiple organ systems, including the endocrine and
nervous system
What is a homeostatic set point? - 🧠 ANSWER ✔✔The level in where the
temperature of the body is maintained.
,Which organs are involved in water, and glucose balance? - 🧠 ANSWER
✔✔The small intestine is involved with balancing water. The pancreas is
involved in balancing glucose.
Where do different molecules enter your body? - 🧠 ANSWER ✔✔The Blood
Stream.
How are they absorbed? - 🧠 ANSWER ✔✔osmosis
How do they get to other regions of the body? - 🧠 ANSWER ✔✔Through
the blood stream
What are capillaries? - 🧠 ANSWER ✔✔any of the fine branching blood
vessels that form a network between the arterioles and venules.
What is interstitial space? - 🧠 ANSWER ✔✔space/fluid in BETWEEN cells
How do different types of molecules (water, glucose, oxygen, sodium,
chloride) cross cell membranes and travel between different organs? - 🧠
ANSWER ✔✔Cell membrane is semipermeable to water. Oxygen move
across cell membranes simple diffusion, a process that requires no energy
input and is driven by differences in concentration on either side of the cell
, membrane. Food is broken up through digestion and diffuse into the blood
through microvilli in the intestinal wall.
How is water regulated in your body? - 🧠 ANSWER ✔✔Homeostasis
What is osmosis and what does it have to do with water balance? - 🧠
ANSWER ✔✔The diffusion of water to create an equilibrium with salt.
Where does the water in your body come from? - 🧠 ANSWER ✔✔Liquids,
foods and cellular respiration.
How does your body eliminate water? - 🧠 ANSWER ✔✔Through urinating,
sweating, and feces.
Which organ systems are involved in water balance and what is their role?
- 🧠 ANSWER ✔✔kidney regulates by controlling water concentration in
blood plasma
What happened to Cynthia Lucero? - 🧠 ANSWER ✔✔Through the
consumption of too much water she flooded her cells to balance the
equilibrium of solutes and thus caused swelling of the cells
