(a) Describe the system of lymph vessels. (b) Explain how lymph is returned to the blood. How does the structure of a lymph node allow lymphocytes and macrophages to perform their protective function? Describe how the cardiova...
4. Immune and Inflammatory Responses to COVID-19 Host innate and adaptive immune cells, particularly lymphocytes (T cells, B cells, and natural killer (NK) cells), are called upon to defend against SARS CoV-2 viral invasion and tissue damage [12,15]. The optimal immune response in humans...

[167]. The function of tumour-specific CD8+T lymphocytes is impaired under acidic conditions, which manifests in decreased cytokine secretion and cytolytic activity [168]. Intriguingly, acidic niches in lymph nodes have a physiological role in suppressing resident T cells [169], and this mechanism...
