- Colourless tissue fluid
- Digestive juice
- Hormone
Q2.Which vessels transport lymph throughout the body?
- Arteries
- Veins
- Lymph vessels
- Capillaries
Q3.One important function of the lymphatic system is to:
- Pump blood throughout the body
- Produce digestive enzymes
- Help defend the body against infections
- Carry oxygen to body cells
Q4.Which structure filters lymph and helps fight disease-causing microorganisms?
- Alveoli
- Nephrons
- Lymph nodes
- Villi
Q5. A student sprains an ankle while playing football. The injured area becomes swollen after some time. Which body fluid is mainly associated with this swelling?
- Saliva
- Lymph
- Gastric juice
- Sweat
Q6.The lymphatic system helps in the absorption of:
- Proteins from the stomach
- Fats from the small intestine
- Water from the kidneys
- Oxygen from the lungs
Short questions
Q1.What is lymph? Mention any two of its functions.
Q2. State any two differences between blood and lymph.
Q3.Why are lymph nodes important for maintaining good health?
Q4.A student notices swelling near the neck during an infection. Explain how the lymphatic system may be involved in this situation.
Q5.Describe the role of the lymphatic system in maintaining the balance of body fluids.
Q6.Explain how the lymphatic system helps in the absorption and transport of fats.
Q1.Describe the structure and functions of the lymphatic system. Explain how lymph vessels and lymph nodes work together to maintain the body's health.
Q2.Compare blood and lymph with respect to:
Colour
Composition
Circulation
Main functions
Type of vessels involved
Present your answer in a suitable table.
Q3.During a school awareness programme, a doctor explains that a healthy immune system depends on the proper functioning of the lymphatic system. Discuss how the lymphatic system protects the body from infections and supports overall health.
Q1.Read the following case:
A doctor explains to a patient that after a minor injury, some tissue fluid enters lymph vessels before eventually returning to the bloodstream.
Based on your understanding of the lymphatic system:
Explain how lymph is formed.
Describe how lymph returns to the blood.
Discuss the importance of this process in maintaining body fluid balance.
Q2.A biology teacher prepares the following flow chart:
Blood Capillaries → Tissue Fluid → Lymph Vessels → Lymph Nodes → Bloodstream
Explain each stage of the flow chart and describe the role of each component in maintaining the normal functioning of the body.
Q3.Read the following observations:
Tissue fluid collects around body cells.
Some fluid enters lymph vessels.
Lymph passes through lymph nodes before returning to the bloodstream.
Fats absorbed in the small intestine are transported through lymph.
Using these observations, explain how the lymphatic system contributes to fluid balance, immunity, and nutrient transport in the human body.
