Answer:
No adaptive immune responses would occur during pathogen attack
Explanation:
The lymphatic vessels are required in the migration of dendritic cells and to transport antigens from the interstitium of peripheral tissues to the lymph nodes, in which the T cells are activated to become effector cells. Moreover, the T (and B) effector cells move through lymph vessels to encounter those antigens presented by dendritic cells. In consequence, the lymphatic vessels have critical functions during adaptive (acquired) immune responses.
According to Sigmund Freud, human personality is complex and has more than a single component. In his famous psychoanalytic theory of personality, personality is composed of three elements. These three elements of personality—known as the id, the ego, and the superego—work together to create complex human behaviors.
Each component not only adds its own unique contribution to personality, but all three elements interact in ways that have a powerful influence on each individual. Each of these three elements of personality emerges at different points in life.
