Kupffer cells are phagocytes located in the?
Kupffer cells are phagocytes located in the liver. They help clear debris, pathogens, and aged blood cells from the bloodstream, contributing to the liver's overall function in immune surveillance and detoxification.
Where do macrophages destroy old red blood cells?
Macrophages primarily destroy old red blood cells in the spleen, although this process can also occur in the liver and bone marrow. The spleen serves as a key organ for filtering the blood and removing aged or damaged erythrocytes. Once engulfed, macrophages break down the hemoglobin within red blood cells, recycling iron and other components for future use.
Which function do skin stem cells perform?
Skin stem cells replace lost skin cells.
Were the aged crown there comet wisdom in the story of aged mother?
Yes, in the story of "The Aged Mother" wisdom is portrayed through the aged mother's experiences, teachings, and selflessness. The aged mother imparts valuable lessons about love, sacrifice, and nature, highlighting the deep wisdom that comes with age and experience.
Explain how apoptosis can prevent abnormal cells from becoming tumors?
Apoptosis might be seen as part of the body's overseeing/managing/protecting mechanism. Apoptosis is associated with cell death; a programmed cell death, where "abnormal" cells, which either cannot function properly (aged, injured, etc), or are potential threat to the organism (infected, mutated), have to die. By activating apoptosis of those cells, the body stops their proliferation. If this mechanism gets impaired (for example tumour suppressor genes, like p53, cannot promote apoptosis), the uncontrolled proliferation of the abnormal cells could lead to malignancy.
How are aged and damaged erythrocytes removed from circulation?
Aged and damaged erythrocytes are primarily removed from circulation by the spleen, where specialized macrophages recognize and phagocytize these defective cells. The liver also plays a role in this process, filtering blood and removing senescent red blood cells. In addition, the reticuloendothelial system contributes by breaking down hemoglobin from these cells, recycling iron and producing bilirubin as a byproduct. This ensures the maintenance of healthy red blood cell populations and proper metabolic functions.
What is the blood component filtered out by the spleen?
the aged red blood cells and antigen-antibody complex
What cells do you have in the liver?
hepatic cells.
What is the fate of aged or damaged red blood cells?
After about 90 to 120 days they get brittle and are filtered from the blood (mainly) by the liver and the spleen. Most of the chemicals are released into the blood where they are taken up by the bone marrow and used in the production of new red blood cells. But a fair amount of hemoglobin is broken down by the liver and is added to the bile - where its only function is to color your solid waste.
Define the meaning of ebagoctosis?
The process by which a cell engulfs particles such as bacteria, other microorganisms, aged red blood cells, foreign matter, etc. The principal phagocytes include the neutrophils and monocytes (types of white blood cells).
True or false older red blood cells may be destroyed in the spleen?
True. There are blood capillaries within the red pulp of the spleen. Older, more fragile red blood cells may rupture as they pass through these capillaries and the resulting cellular debris is removed.
Can spleen destroy normal RBC's?
Yes, one of the major functions of the spleen is to remove aged or damaged red blood cells (erythrocytes) from the circulating blood stream. If the body has produced antibodies against red blood cells, the spleen will remove the red blood cells with antibodies on them from circulation, destroy them and package the bits and pieces for recycling into new red blood cells.
Which of the spleen functions in the adult can be performed by bone marrow?
Bone marrow can perform the function of producing and storing blood cells, which is one of the main functions of the spleen in adults. Both bone marrow and the spleen play crucial roles in the immune system by producing and maturing white blood cells.
Dead and injured white blood cells are removed from circulation by the?
spleen and liver. The spleen filters out damaged or aged white blood cells, while the liver helps in breaking down and recycling their components. This process is essential to maintain a healthy immune system.
Kupffer cells are phagocytes located in the?
Kupffer cells are phagocytes located in the liver. They help clear debris, pathogens, and aged blood cells from the bloodstream, contributing to the liver's overall function in immune surveillance and detoxification.

What organs acts most directly to remove old red blood cells frm circulation?
The organs that act most directly to remove old red blood cells from circulation are the spleen and the liver. The spleen filters the blood, identifying and destroying aged or damaged red blood cells, while the liver processes the byproducts of red blood cell breakdown, such as bilirubin. Together, these organs play a crucial role in maintaining healthy blood composition and recycling iron for new red blood cell production.
