Loss of recoil = "Lack of C Compliance 2. TypeI Lung compliance 3 C Central 4 27. Where is surfactant found?

Answer 1

18.The oxygen is carried to each cells via the blood to the desired tissue.The mixing of this is called as oxyhemoglobin.Nearly 25% of the oxygen is offloaded to the tissues

Ans:A.25%

19.The chief function of the stretch receptor are its response to the expansion of the muscles in important organs. These mechanoreceptors are responsible for sending messages to the respiratory receptor present in the brain.Usually when lung expands ,the respiratory rate decreases this is mainly due to the pressure and stimulated by theHerring Breuer reflex

Ans:H.what breathing receptors responds to changes in pressure in airway?

20.The main function of the Helper T cells is to activate the immune system to release T cells and kill or destroy the specific foreign or abnormal cells usually they are cancerous cells

Ans:E.activate cytotoxic T cells

21.The central receptor are one which responds when the level of CO2 is dramatically increased in the artery

Ans:G.Primarily central chemoreceptors monitor CO2 level

22.The pulmonary surfactant are produced by a type 2 alveolar cells.These cells are lipoprotein in nature having both hydrophilic and hydrophobic actions and this reducing the tension in the alveoli

Ans:B.type II

23.There are certain receptors in the lungs which responds to be even mild stimulation or invasion of foreign organisms either living or non living.They are called as irritant receptors

Ans:C.what breathing receptors are stimulated by noxious gases,smoke, inhaled dust,very cold air, etc.

24.The cytotoxic T cells has the capability to destroy the cancer cells by killing the antigen present in it.

Ans:D.cytotoxic T cells

25.Lung compliance or pulmonary compliance refers to the capability  of the lungs to stretch and expand when the lung is still without any major movement.

Ans:F.is the ease with which the lungs can be inflated
