Which of the following inflammatory signs specifies pain?
Tumor — swelling (puffiness, edema). Calor — heat. Dolor — pain.
Which of the following blood cells function primarily as phagocytes *?
Neutrophils are the most phagocytic of these cells: they are the most abundant white blood cell, and can be identified by their granular cytoplasm and lobulated nuclei (usually 2-5 lobules). They are formed from myeloid stem cells found within bone marrow.
Which of the following is an example of a chemical barrier to infection?
Chemical barriers against infection include enzymes in tears, saliva and mucus that break down the surface of bacteria. The acid in sweat and in the stomach kills cellular pathogens and there are anti-bacterial proteins in semen (the fluid that contains male sperm).
Which white blood cells functions primarily as Phagocytotic cells?
In humans, and in vertebrates generally, the most-effective phagocytic cells are two kinds of white blood cells: the macrophages (large phagocytic cells) and the neutrophils (a type of granulocyte).
Which type of WBC is involved in the inflammatory response?
The main phagocytes involved in acute inflammation are the neutrophils, a type of white blood cell that contains granules of cell-destroying enzymes and proteins. When tissue damage is slight, an adequate supply of these cells can be obtained from those already circulating in the blood.
Which leukocyte is responsible for inflammation response?
Basophils are chiefly responsible for short-term inflammatory response (particularly from allergy or irritation) by releasing the chemical histamine, which causes the vasodilation that occurs with inflammation.
What two types of defense cells are phagocytic?
There are two types of phagocytes namely macrophages and neutrophils. These cells are found in the tissues and blood. In the beginning, phagocytes recognize and bind pathogens and then use the plasma membrane to surround and engulf pathogens inside the cell.
What are the two types of phagocytes associated with innate defense?
Two types of phagocytes are macrophages and neutrophils, which are both essential cells involved in immunity. They are particularly involved in the innate immune system, which is effective from the beginning of an individual’s life.
What is a nonspecific defense?
Nonspecific defense mechanisms include the skin, mucous membranes, secretions, excretions, enzymes, inflammatory responses, genetic factors, hormonal responses, nutritional status, behavior patterns, and the presence of other diseases.
What type of barrier is the skin chemical or physical?
Skin. The skin covers almost all parts of your body to prevent infection from pathogens. If it is cut or grazed it immediately begins to heal itself, often by forming a scab, which prevents infection as the skin acts as a physical barrier.
Are phagocytic have a Trilobed nucleus and make up the largest percentage of leukocytes?
E) neutrophils. __________ are phagocytic, have a trilobed nucleus, and make up the largest percentage of leukocytes. These leukocytes produce heparin and histamine; they play a role in inflammatory and allergic reactions.
