mass transport

• What does mass transport refer to in biological systems?

  Mass transport refers to the movement of particles, molecules, or substances from one location to another within a system.
• How does mass transport function in plants?

  In plants, mass transport moves water and nutrients from the roots to the leaves.
• Why is mass transport crucial in biology?

  It is crucial for the distribution of nutrients, waste products, and other essential molecules throughout an organism.
• How does mass transport function in humans?

  In humans, mass transport is responsible for delivering oxygen from the lungs to various body tissues.
• What is a simple analogy for mass transport in living organisms?

  - Mass transport is like a delivery system. - It carries important substances like food, water, and oxygen to where they are needed in the body.
• What is the primary function of mass transport in fish?

  Mass transport in fish refers to how important substances like oxygen, nutrients, and waste products move around inside a fish's body.
• How do fish take in oxygen from their environment?

  Fish take in oxygen from the water through their gills.
• What happens to oxygen after it enters a fish's gills?

  The oxygen enters the fish's bloodstream and is transported throughout the fish's body by the circulatory system.
• What are the two main mechanisms of mass transport in biological systems?

  1. Bulk flow: Movement of substances in large quantities through vessels or tubes. 2. Diffusion: Movement of particles from an area of high concentration to an area of low concentration.
• What is bulk flow in the context of mass transport?

  Bulk flow is the movement of substances in large quantities through vessels or tubes, such as blood circulation in fish.
• How does diffusion occur in fish gills?

  Diffusion occurs when oxygen moves from the water (high concentration) into the blood (low concentration) across the gill membranes.
• What is the role of pressure differences in mass transport?

  Pressure differences created by the heart drive blood flow in the circulatory system.
• How do osmotic gradients affect mass transport in fish?

  Osmotic gradients are important for water movement across cell membranes and in processes like osmoregulation in fish.
• What role do concentration gradients play in mass transport?

  Concentration gradients drive diffusion, allowing substances to move from areas of high concentration to areas of low concentration.
• What is active transport in the context of mass transport?

  Active transport is the movement of specific molecules against their concentration gradients, using energy (ATP).
• What are the key areas where mass transport is important in biological systems?

  1. Nutrient distribution 2. Waste removal 3. Gas exchange 4. Temperature regulation 5. Hormone circulation
• Why is mass transport particularly vital for fish?

  Mass transport is vital for fish due to their aquatic environment, which requires efficient oxygen delivery and waste removal.
• What is the countercurrent exchange system in fish gills?

  The countercurrent exchange system is a highly efficient mass transport mechanism that maximizes oxygen uptake from water.
• How does mass transport relate to fish migration?

  Mass transport is crucial for long-distance swimmers like salmon or tuna, allowing for sustained swimming over vast distances.
• How do deep-sea fish adapt their mass transport systems?

  Deep-sea fish often have specialized hemoglobin to efficiently transport oxygen in low-oxygen environments.
• Why is understanding mass transport important in aquaculture?

  Understanding mass transport is vital for designing efficient fish farming systems, ensuring proper oxygenation and waste removal.
• How can changes in fish physiology indicate environmental issues?

  Changes in fish physiology, particularly in their mass transport systems, can be indicators of environmental pollution or climate change effects.
