Macrophages are the first line of defense against a foreign substance. The macrophage cell envelopes and begins to break down the foreign substance into smaller pieces allowing the lymphocytes (T cells and B cells) to attack and destroy the foreign substance.
There is structural difference between xylem and phloem. This is because their function is also different. Had there been no difference in structure, how these could have performed different function?
What is the difference between structuralism and functionalism in Psychology Schools?
Phagocytes, such as neutrophils and macrophages, can pass from the blood to tissue fluid through a process called diapedesis. This involves the phagocytes adhering to the endothelial cells lining blood vessels, then squeezing between these cells to exit the bloodstream. Factors like chemokines and other inflammatory signals help attract phagocytes to areas of infection or injury, facilitating their movement into the tissue fluid. Once in the tissue, they can perform their role in immune defense by engulfing pathogens and debris.
Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
The amount of increase or decrease in a function is determined by the difference between the final value and the initial value of the function. If the final value is greater than the initial value, there is an increase; if the final value is less than the initial value, there is a decrease. The magnitude of this difference indicates the extent of the change in the function.
well...phagocytes are mainly part of the immune systems defense system, like when there is an inflammatory response. While lymphocytes are mainly for when the immune system attacks a foreign organism. However, lymphocytes can become phagocytes that's why i didnt say that they were part of a certain sector of the immune system.
Lymphocytes and some mononuclear phagocytes can recirculate between lymphoid and non-lymphoid tissues. This helps in allowing lymphocytes to be exposed to the antigens which they recognise and is, therefore, valuable in the distribution of effector cells of the immune response to the sites where they are needed http://www.fasebj.org/cgi/reprint/02-0787fjev1.pdf
Lymphocytes are a type of white blood cell that plays a crucial role in the immune system, helping to fight infections and diseases. Absolute lymphocytes refer to the total count of lymphocytes in a specific volume of blood, usually expressed as cells per microliter. The term "lymphocytes" can refer to their presence and function generally, while "absolute lymphocytes" provides a quantitative measure of their concentration. This distinction is important for diagnosing various medical conditions, as abnormal lymphocyte counts can indicate underlying health issues.
fundamental difference between a polynomial function and an exponential function?
the difference is ,a structure is where it is placed and the function is what it daos

Monocytes are granulocytes, meaning they have small granules in them. Lymphocytes do not. Histologically, you should be able to see some peripheral cytoplasm on a lymphocyte but not on a monocyte.
the reactive : change in morphology but without malignant atypical : also chagne in morpholgy but with malignant
A function has no repeated x values
A function has no repeated x values
