Answer:
Secondhand smoke is the combination of smoke from the burning end of a cigarette and the smoke breathed out by smokers. Secondhand smoke contains more than 7,000 chemicals. Hundreds are toxic and about 70 can cause cancer.
Explanation:
It is harmful too
Answer:
D
Explanation:
The point of hands only CPR is to make it easier on those with a lack of training a give them a way to give care to someone who needs it even if they do not know how to, the point is that if you are not in sports med or EMT training then you will at least be able to help if no one else is around, otherwise use an AED
Answer: Option D. "Heme"
Explanation:
Deoxyhemoglobin can be defined as a form of which has no oxygen binded to the hemoglobin.
When deoxyhemoglobin is replaced with oxyhemoglobin then the oxygen binds to the heme component of the hemoglobin protein in red blood cells.
Each heme group has iron atom that has the ability to bind to oxygen (02) molecule.
Four oxygen molecules bind to a single hemoglobin protein.
Hence, the correct answer is option D "Heme".
3. PR.
It stands for per rectum
It works according to the guidelines set by the authorities
Answer:
The white blood cells i.e. granulocytes and macrophages are specifically stimulated by GM-CSF in response to chemotherapy in cancer patients.
Explanation:
The colony stimulating factors (CSFs) are the regulators of granulocytes and macrophages in blood. The CSFs has the potential to regenerate the white blood cells damaged during chemotherapy. Thus, CSFs mobilize the stem cells to enhance the immune process and produce hematopoietic cells such as granulocytes, macrophages in cancer patients. The CSFs resemble hormones that are specifically targeted to produce blood cells in specified regions where the quantity of those cells is low. The CSFs belong to a group of regulatory factors also known as cytokines and does not produce only a single cell type but stimulates colonies of different blood cell types for any specific organ. Hematopoietic cells produced by CSF are step-wise and formation of blast colonies take place initially. Afterwards, the blast cells regenerate and differentiated into multiple progenitor cells consisting of granulocytes, monocytes, macrophages, eosinophills, erythroids, and lymphocytes. The progenitor cells in the granulocyte-macrophage lineage matures into neutrophilic granulocytes and macrophages.
Out of all types of CSF colonies, the Granulocyte-Macrophage (GM-CSF) colony is specially involved in regenerating immune responses in cancer patients. These cytokines stimulates the dendritic cell formation and produces dendritic activity against the cancerous cells. These GM-CSF colonies enhance the immune response of host against melanomas, tumors by reducing their growth and inducing remission. Hence, it can be said that granulocytes and macrophages are infection protective cells and elevates dangerously low levels of white blood cells in cancer patients following chemotherapy. The GM-CSF induction regenerates the bone marrow which is damaged and improves stem cells production.
