Worked Solution & Example Answer:Consider the following diagram of a lymph node - VCE - SSCE Biology - Question 5 - 2015 - Paper 1
Step 1
Describe the role of the structure labelled A, found within the efferent lymphatic vessel.
Answer
The structure labelled A in the efferent lymphatic vessel plays a crucial role by ensuring that lymph fluid flows in one direction, away from the lymph node. This directional flow prevents the backflow of lymph, facilitating the efficient transport of immune cells and lymphatic fluid towards the circulatory system.
Step 2
Name and describe the role of one type of immune cell found within these clusters that plays a role in the innate immune response.
Answer
One type of immune cell found within the clusters of the lymph node is a phagocyte. Phagocytes are essential components of the innate immune response, as they engulf and destroy pathogens through a process known as phagocytosis. By doing so, they help eliminate infectious agents and play a significant role in initiating the adaptive immune response.
