Direct link to Ian Cox's post “Most bacteria is good and...” Most bacteria is good and makes our body function better. If we didn't have any bacteria in our body, we would die. A lot of the bacteria which gets into your body will actually help fight off bad bacteria, viruses, etc! A very small percentage of the bacteria in our body is bad, so when there is one, the white blood cells in addition to some of the good bacteria will help fight it off. 1% is actually plenty, because if the body can get to it before it multiplies constantly, then it can get rid of the bad thing quickly and we won't even know we were sick.

Direct link to SpinosaurusRex's post “The nucleus is a membrane...” The nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. It is commonly the most prominent organelle in the cell. The nucleus is surrounded by a structure called the nuclear envelope. This membrane separates the contents of the nucleus from the cytoplasm. The cell's chromosomes are also housed within the nucleus. Chromosomes contain DNA which provides the genetic information necessary for the production of other cell components and for the reproduction of life. (25 votes) Rosse 8 years agoPosted 8 years ago.

Direct link to Wugee's post “Think of single-celled or...” Think of single-celled organisms. They are among the first of all life-forms, and they are incredibly simplistic. Evolution is the process of becoming better and adapting, therefore advanced beings have advanced biology. It would definitely be hard for an amoeba to formulate the answer to a differential equation with simple flagellate motions. However, our brains are capable of doing so thanks to the multiple support systems, which are complicated biology. Hope this helped! (12 votes) Seye.Solabomi 7 years agoPosted 7 years ago.

Don't they also have to travel through the same capillaries? • (5 votes) Jonathan Widarsa 8 years agoPosted 8 years ago. Direct link to Jonathan Widarsa's post “Firstly, there are three ...” Firstly, there are three types of capillaries in our body - continuous, fenestrated and sinusoid. The major difference n these three types are that continuous capillaries are less permeable than fenestrated, having sinusoid to be the most permeable and big-sized capillaries in our body. Apparently, the main functions of these types vary accordingly with the permeablity of the vessels and for sinusoid, as it is the largest capillary, allows larger molecules to flow through it, including white blood cells of any kind. Another idea unrelated to this also explains that the role of leukocytes are to fend off external breaches by activating immune system, phagocytosis, releasing substances, etc. Thus, leukocytes are able to escape through any vessel walls to arrive at the needed regions of the body ASAP. So they do not have to pass through the capillaries. I've checked some biology sites and these are all informations I could gather, hope it helps :). (8 votes) YEBrandy 8 years agoPosted 8 years ago.

Plasma, for instance, can carry anti-A antibodies, anti-B antibodies, both antibodies, or none depending on blood type. This is why blood type still must be considered for plasma and platelet transfusions. Does that help? (3 votes) gianina carletti 4 years agoPosted 4 years ago.

Direct link to Tybalt's post “While everybody has stem ...” While everybody has stem cells, the cells used for research primarily come from human embryos. Here's the problem: when you harvest stem cells from an embryo, you destroy it. Killing a human being is typically viewed as murder; however, this being an unborn child raises several questions. Would it still be classified as murder if the child was never born? Can it even be classified as murder if the human being was very early in development, to the point where it was still only a mass of cells? Does it feel anything at that point? Is it part of the woman's body, or is it its own being? Much of the questions asked about the matter tie closely to the issue of abortion. It is an ethical issue because when exactly something becomes its own being is unclear, and there is a clear and significant pro (forwarding science for the better) and a clear and significant con (the death of a potential child) to be seen. There is no definite answer to this question, and it is ultimately up to your morals and views to give you the answer. Does this help? (3 votes)Want to join the conversation?
My question is: Where are hematopoietic stem cells produced?
I'm referring to the section: Stem cells and blood cell production.
Approximately 2.4 million new erythrocytes are produced per second in human adults. In a normal adult about half a liter are produced by the bone marrow every week.
High red blood cell count -
high red cells count is caused by a disorder called Polycythemia Vera. This is a genetic condition that causes the bone marrow to produce too many blood cells. People with polycythemia have an increase in hematocrit, hemoglobin, or red blood cell count above the normal limits.
