Comparing B and T lymphocytes (TH = helper T lymphocytes, TC = cytotoxic T lymphocytes) Select one: a. Both T lymphocytes and B lymphocytes are not involved in the adaptive immune response to viral pathogens, like corona virus causing Covid-19 b. Both B and T lymphocytes only mature in the bone marrow c. B lymphocytes do not have nuclei, while T lymphocytes all have nuclei d. B cell plasma cells are responsible for the production of antibodies, T cells are involved in helping coordinate the humoral response or mediating cellular adaptive immunity e. T lymphocytes belong to two categories: TH cells that coordinate the humoral immune response and TC lymphocytes that lyse and phagocytose dead bacterial cells

Transcript

00:01 The comparison about b cells and t cells, that is b lymphocytes and the lymphocytes is given and it is to select the one.

00:07 The first option says that both b cells and t cells are not involved in adaptive responses like viral pathogens for example that is corona which is caused in the recent times the coronavirus correct so this statement is not true or we eliminate this we adaptive response is what which has been adopted by attack of any pathogen or by vaccination so it has been adopted one after pathogen attack or after a vaccination process so which is done during the attack of coronavirus pandemic correct and during the adaptive responses both t cells and b cells are involved so this is an incorrect statement therefore we eliminate this secondly b cell and t cell both mature in bone marrow it's incorrect since t cells matures in thymus.

01:05 Further, b cell does not have nuclear rest t cells and nuclear again incorrect.

01:12 Only rbcs in the human rbc and thrombocytes are having no nucleus.

01:25 These are the cells with no nuclear rest all of them will have nuclear.

01:29 So again a wrong statement.

01:31 Next b cell is going to produce antibody.

01:34 That is involved in a humoral response sorry that is it's not involved in human response it is involved in production of antibodies whereas t cells they are either involved in humorous humoral response or cellular adaptive immunity now this is a correct statement because t cells have again two types of cells that is t helper cells called as t h cells and tc cells called as cytotoxic cells so these cytotoxic cells are doing a patrolling kind of work which will give the immunity by directly attacking a compromised cell and it is going to release some chemicals and that's how it will digest the compromised or attacked cell...
