What will happen if a man runs out of sperm?

If a man runs out of sperm, he will no longer be able to ejaculate during sexual activity. This may result in infertility and make it difficult to conceive a child. However, it should be noted that sperm production is a continuous process, and the body can typically regenerate sperm over time.

What does a white blood count show?

The "white blood count" is the number of white blood cells (WBCs) per cubic millimeter. Normal counts range from 4000 to 10,500. (Normal red blood cell counts are in the range of three to five million per cubic millimeter, which is why blood is red.) The white blood cells are differentiated into 5 major subgroups or "lines," each of which has a different function. Mostly, they are involved in protecting the body from disease, dectroying invaders, cleaning up after injuries and such things. Hence, one can tell if a disease process is present by looking at the total WBC count and the proportions of the different WBC lines. One can also detect the presence of leukemia or other blood disorders from the WBC count. Doctors will watch the WBC count changes over time to gauge the efficacy of disease treatments.

What type of energy does the earth emit?

The Earth emits thermal energy in the form of heat as a result of its core's high temperature. This thermal energy is primarily generated by the decay of radioactive isotopes and residual heat from Earth's formation.

How long can blood be kept in the blood bank?

Blood can generally be stored in the blood bank for up to 42 days. However, different components of blood, such as red blood cells and platelets, have varying storage durations. Red blood cells can be stored for up to 42 days, while platelets have a much shorter shelf life of around 5 days. Plasma can be frozen and stored for up to a year.

What cpk stands for in blood test?

what is cpk. How is it increased by crestor?

what is crestor?

CPK, also known as CK and Creatine phosphokinase, is more formally called Creatine Kinase. This is a test performed to determine whether or not the individual has had a heart attack. Higher levels of CK indicate injured muscles or heart cells. Very heavy exercise, excessive drinking, injury to person via car accident or fall or etc., and drugs that lower cholesterol can all increase the level of CK in the blood.

CK levels can be increased by drugs such as Crestor because it damages muscle. Crestor is a cholesterol-lowering medication or statin.

What is copath?

Not sure if this is the right CoPath but here goes anyway.

CoPath is (or was) an anatomic pathology laboratory system. So, from the beginning then....

Anatomical pathology is the diagnosis of diseases/illnesses through the examination of body tissues/organs/cells either on a macro scale (i.e. looking at a body or whole organ like in an autopsy) or micro scale (i.e. tissue parts like a biopsy).

The folk who do this use an IT system to log the requests and sample IDs, record results, have results checked and then authorised and then store those records for the future.

CoPath is one such system. Created by Dynamic Healthcare Technologies Inc.who were subsequently taken over by Cerner Corporationin 2001 and renamed Cerner DHT Inc.

Note dht's website now is redirected to Cerner's website. (This take over also created two (2) CoPaths if you will. One is owned by Cerner and the other is owned by Sunquest Information Systems

What are the two most common blood types in the US?

The two most common blood types in the US are O positive and A positive.

Is there a condition where a man is born without the ability to produce sperm?

Yes, a condition called congenital bilateral absence of the vas deferens (CBAVD) can result in a man being born without the ability to produce sperm. This condition is typically caused by abnormalities in the development of the male reproductive system. A man with CBAVD may still have functional testicles but is unable to transport sperm due to missing or blocked vas deferens.

Bone cells that liquefy bone matrix and release calcium to the blood are called?

Osteoclasts are bone cells responsible for breaking down and resorbing bone tissue, releasing calcium and minerals into the bloodstream. They play a crucial role in bone remodeling and maintenance.

What is a complete blood count CBC?

The complete blood count (CBC) is one of the most commonly ordered blood tests. The complete blood count is the calculation of the cellular (formed elements) of blood. These calculations are generally determined by special machines that analyze the different components of blood in less than a minute.

A major portion of the complete blood count is the measure of the concentration of white blood cells, red blood cells, and platelets in the blood.

How long does a culture test take?

A culture test can take anywhere from a few days to a few weeks to produce results, depending on the type of test being done and the specific organism being cultured. Some tests may provide preliminary results sooner, but final results may require a longer incubation period.

What is the class of antibody first secreted in response to a new antigen?

IgM is the class of antibody first secreted in response to a new antigen. It is produced during the initial immune response and helps to activate other components of the immune system.

What are white blood cells called when found in urine?

pyuria, means that pus and abnormal levels of leukocytes are present in the urine; a postitive result when testing for a urinary tract infection (UTI).

What happens if urea accumulates in the blood?

If urea accumulated in the blood, then you would probably die, because urea is technically a diluted version of ammonia, which is highly toxic.
You would die because urea comes from the toxic nitrogenous waste in our body, and although less toxic, is still harmfull.

A RBC has a 120 day life span if an average adult has 5 L of blood and each microliter contains 5 million red blood cell's how many new cells must be produced each second to replace RBC population?

To calculate the number of new red blood cells that must be produced per second to replace the RBC population, you would need to consider the total number of red blood cells in the body and their lifespan. Given that an average adult has 5 liters of blood (which is equivalent to 5,000,000 microliters) and each microliter contains 5 million red blood cells, you would multiply these values to find the total number of red blood cells in the body. Then, you would divide this total by the 120-day lifespan of red blood cells to determine how many cells need to be produced each second.

Why isn't protein normally found in urine?

Protein isn't normally found in urine, because so many people these days are on

Methamphetamine, a very strong drug used by individuals seeking an easy escape. If this drug is abused, the protein from the mitochondria in your cells don't diffuse through the cells into the stream of urine.

Can white blood cells ingest pathogens?

Yes, white blood cells can ingest pathogens through a process called phagocytosis. This allows white blood cells to destroy and eliminate harmful pathogens, such as bacteria and viruses, from the body.

What is baso in hematology test?

Baso or basophils are cells in the blood that are usually relatively low. When there is an increase in basophils, this could signal an allergic reaction, and inflammatory process, or rarely leukemia.

In an experiment a group that receives treatment is called what?

The group that receives treatment in an experiment is typically referred to as the "treatment group" or "experimental group." This group is exposed to the intervention or manipulation being studied to determine its effect.

What is the first wbc to arrive at the site of tissue damage?

Neutrophils are the first white blood cells to arrive at the site of tissue damage. They are specialized in engulfing and destroying pathogens, debris, and damaged cells to help initiate the inflammatory response and promote tissue repair.

Can a DNA test be conducted between a brother and a sister who have a common mother to see if they have the same father?

In creation a zygote from a father and mother ..DNA is made from 21 chromosomes from a father and 21 others from amother which the sperm and the ovule contains .. so every zygote from the same mother and father have at least 21 chromosomes common in their DNA because they came from the same source but they will differ in some characters according to the sequences of the bases on The DNA so the answer is yes

What is the evidence against therapeutic cloning?

Arguments against therapeutic cloning include concerns about the destruction of human embryos, ethical considerations regarding the creation and manipulation of human life, and potential risks of genetic abnormalities or unintended consequences in the cloned cells. Additionally, there are challenges in regulating and overseeing the use of therapeutic cloning to ensure it is used responsibly and ethically.

Diagnosis 793.1 means what?

Diagnosis code 793.1 refers to "nonspecific (abnormal) findings on radiological and other examination of body structure." It is not specific to any particular condition or disease, and further evaluation may be needed to determine the underlying cause of the abnormal findings.

When the elodea leaf is moved from salt solution n placed back in water what happens to the cells?

When you deal with problems like this, you need to consider diffusion and osmosis. In this case, you would refer to diffusion, which is the movement of water across a membrane from high concentrations to low concentrations (to try to balance the concentrations). First consider what happens to the cells when you place the elodea leaf in the salt solution; the water in the cells tries to balance the high concentration of salt (sodium chloride) in the surrounding solution, so the water leaves the leaf, thus the cells shrink. Now when you put the elodea leaf into regular water again, there is a higher concentration of water in the surrounding environment compared to inside the leaf's cells, so in attempt to balance concentrations, water goes INTO the cells, thus the cells in the elodea leaf swell (expand).
