Your spleen’s main function is to act as a filter for your blood. It recognizes and removes old, malformed, or damaged red blood cells. When blood flows into your spleen, your spleen performs “quality control”; your red blood cells must pass through a maze of narrow passages.
When worn out red blood cells are removed from circulation by?
Old or damaged RBCs are removed from the circulation by macrophages in the spleen and liver, and the hemoglobin they contain is broken down into heme and globin.
What is the medical term used to describe any substance that the body regards as being foreign?
Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens.
Which term means a medication which kills or damages cells?
Cytotoxic substances damage or kill cells. Medications like chemotherapy are cytotoxic.
What term describes the function of destroying worn-out erythrocytes and releasing their hemoglobin for reuse?
hemolysis, also spelled haemolysis, also called hematolysis, breakdown or destruction of red blood cells so that the contained oxygen-carrying pigment hemoglobin is freed into the surrounding medium.
What are the 4 main functions of the lymphatic system?
Your lymphatic system, part of your immune system, has many functions. They include protecting your body from illness-causing invaders, maintaining body fluid levels, absorbing digestive tract fats and removing cellular waste.
Is a waste product formed during the removal of worn out red blood cells?
Bilirubin is a breakdown product of the non-iron component of heme, which is cleaved from globin when erythrocytes are degraded.
How is hemoglobin recycled?
Hemoglobin is produced in bone marrow by erythrocytes and is circulated with them until their destruction. It is then broken down in the spleen, and some of its components, such as iron, are recycled to the bone marrow.
What happens to iron that is removed from degraded hemoglobin?
Most of the iron that is removed from degraded hemoglobin is D) recycled to the red bone marrow. This iron is used for the production of new red
What is the medical term for medication capable of inhibiting growth of or killing bacteria?
Bacteriostatic: Capable of inhibiting the growth or reproduction of bacteria.
What medication is capable of inhibiting growth of or killing bacteria?
Antibiotics are generally taken in order to prevent the spread of infections from one person to another. They can either inhibit the growth or kill off certain bacteria types. The most common antibiotics used to treat infections are tetracycline, doxycycline, minocycline, Erythromycin, or Cephalosporin.
Is a medication that is capable of inhibiting the growth of or killing pathogenic bacterial microorganisms?
Antimicrobials is a term used to describe drugs that treat many types of infections by killing or slowing the growth of pathogens causing the infection. Bacteria cause infections such as strep throat, foodborne illnesses, and other serious infections. Antibiotics treat bacterial infections.
Which type of cell eats invading cells?
Neutrophils are phagocytes, cells that consume invading pathogens.
Is a form of treatment that disrupts the blood supply to the tumor?
During chemoembolization, chemotherapy drugs or beads coated with chemotherapy are injected into the artery that supplies blood to the tumor in the liver. This disrupts the blood supply to the tumor and also delivers concentrated doses of chemotherapy to the tumor or tumors.
What is a type of leukocyte that surrounds and kills invading cells?
Some types of white blood cells, called phagocytes (FAH-guh-sytes), chew up invading organisms. Others, called lymphocytes (LIM-fuh-sytes), help the body remember the invaders and destroy them.
What happens to iron when red blood cells are destroyed?
Damaged RBCs can release unbound forms of iron-carrying hemoglobin, which can cause kidney injury, and can lead to anemia, reducing the delivery of oxygen to tissues. If disease-associated RBC damage overwhelms the body’s ability to clear aged RBCs, toxic levels of free iron can be released.
When red blood cells shrink this is called?
A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypotonic solution will swell and potentially burst in a process called hemolysis.
