What is the function of the lymphatic system?
What is the function of the lymphatic system?
- Producing red blood cells and transporting oxygen to the cells
- Digesting food and absorbing nutrients
- Regulating body temperature and maintaining electrolyte balance
- Balancing the fluid content of the blood and surrounding tissues, and participating in the body’s defenses (correct)
How do circulatory systems facilitate the exchange of gases and nutrients in larger animals?
How do circulatory systems facilitate the exchange of gases and nutrients in larger animals?
- Transporting only nutrients to the cells
- Bringing fluids close to the cells for exchange (correct)
- Creating a barrier between cells and fluids
- Removing all fluids from the cells for purification

Study Notes
Circulatory Systems
- Basic elements shared by circulatory systems include a heart, blood vessels, and a specialized fluid.
- In larger animals, circulatory systems facilitate the exchange of gases and nutrients through the transportation of oxygen and nutrients to cells and removal of carbon dioxide and waste.
Lymphatic System
- The primary function of the lymphatic system is to help balance fluids and defend against infection.
- The lymphatic system is also an accessory system that helps to remove waste and excess materials from the body.
Modes of Molecule Movement
- In very small or thin animals, the primary mode of molecule movement is through diffusion, where molecules move from an area of higher concentration to an area of lower concentration.
Circulatory System Functions
- The circulatory system primarily moves oxygen, nutrients, carbon dioxide, and waste from one tissue to another.
- Blood is the specialized medium that carries cells, oxygen, nutrients, carbon dioxide, and waste in the circulatory system.
