Fluid and Solute Transport in the Human Body

What is the primary goal of the body's homeostatic environment?

• To decrease fluid levels

• To increase solute concentration

• To maintain a balance of fluids and solutes

• To enhance energy production

Which type of molecules can pass through the phospholipid bilayer via simple diffusion?

• Large charged molecules

• Glucose

• Tiny non-charged molecules

• Proteins

How does facilitated diffusion differ from simple diffusion?

• It moves molecules from low to high concentration

• It uses special proteins to transport molecules

• It only transports water

• It requires energy

What is the main characteristic of active transport?

• It only occurs in plant cells

• It moves molecules from high to low concentration

• It requires no energy

• It uses ATP to move molecules against the concentration gradient

In osmosis, water moves through a membrane to achieve what?

• Higher solute concentration

• Lower solute concentration

• Homeostasis of water concentration

• Increased energy levels

What can happen to a cell if too much water enters it during osmosis?

• It will swell and possibly rupture

• It will become more rigid

• It will remain unchanged

• It will shrink

How can healthcare professionals use osmosis to benefit patients?

• By increasing blood pressure

• By enhancing protein synthesis

• By reducing oxygen levels

• By manipulating fluid concentrations to correct imbalances

What is the role of oncotic pressure in the capillaries?

• To decrease solute concentration

• To increase blood flow

• To pull water into the capillaries

• To push water out of the capillaries

What creates hydrostatic pressure in the circulatory system?

• Liver function

• Heart contractions

• Kidney filtration

• Lung expansion

What condition can result from low levels of albumin in the blood?

• Hypoxia

• Hyperglycemia

• Hypoalbuminemia

• Hypertension
