Blood

120 days for a normal rbc. a sickle cell lasts only about 20 days

They carry oxygen to every cell of the body needing oxygen. Red blood cells are just carriers of the protein hemoglobin, which actually carries the iron heme that attaches the oxygen for transport throughout the body.

The bone marrow, found within bones, supports and protects organs while producing red blood cells through hematopoiesis. Additionally, bones store important minerals like calcium and phosphorus for maintaining overall bone health and metabolic functions in the body.

It takes the body approximately 120 days to produce one liter of blood. Blood is continually being produced in the bone marrow through a process called hematopoiesis, where red blood cells, white blood cells, and platelets are generated.

White blood cells, or leukocytes, are a part of the immune system to protect the body from diseases and foreign organisms or substances. White blood cells are able to pass through the capillary walls to fight infections and germs that find ways into the body. The number of white blood cells make up about 1% of the blood in a healthy adult.

"B cells" are named after the Bursa of Fabricius where they were first discovered in birds. The Bursa of Fabricius is an organ in birds that is involved in the development of B cells. The "B" stands for "bursa-dependent" in reference to this organ.

Emphysema is a type of chronic obstructive pulmonary disease (COPD) that is characterized by damage to the air sacs in the lungs. This can result in decreased oxygen levels in the blood (hypoxemia) and increased carbon dioxide levels (hypercapnia), leading to respiratory acidosis. Over time, these chemical alterations can affect the body's pH balance and lead to further complications.

Red blood cells lose their nucleus as they mature in order to make space for more hemoglobin, the protein that carries oxygen. Even without a nucleus, they are still considered cells because they have a cell membrane and other cellular components necessary for their function of transporting oxygen in the bloodstream.

The cell membrane in a red blood cell helps to maintain the cell's shape and structure, allowing it to be flexible so it can squeeze through small blood vessels. It also controls what substances can enter and exit the cell, playing a crucial role in the regulation of nutrient and waste exchange. Additionally, the cell membrane contains specific proteins that enable red blood cells to carry oxygen throughout the body.

The red blood cell count would be 2.4 million per cubic milliliter (240 x 10,000).

No, the circulatory system does not produce red and white blood cells. Red blood cells are produced in the bone marrow, while white blood cells are produced in various tissues in the body such as the bone marrow and lymph nodes. The circulatory system is responsible for transporting these cells around the body.

leukocytes are the largest white blood cells.

You Must mean White blood cells.

White blood cells kill bacteria by first engulfing them, this process i believe is called

phagocytocis. They literally eat the bacteria and digest it.

The possible blood types of the child would be B and O. Each parent can pass on a B allele or an O allele, resulting in a 50% chance of the child inheriting a B allele from each parent, making them blood type B. If the child inherits an O allele from one parent and a B allele from the other, they would be blood type B.

No, fish typically do not have nuclei in their red blood cells. Most mature fish red blood cells are enucleated, meaning they do not contain a nucleus. This allows for more efficient oxygen transport in their bloodstream.

An elevated red blood cell count, known as polycythemia, can lead to thickening of the blood, which increases the risk of blood clots and can strain the heart by making it work harder. It can be caused by various factors such as chronic hypoxia, kidney disease, or bone marrow disorders, and should be evaluated by a healthcare professional for appropriate management.

Macrophages are large phagocyte white cells that are found throughout the body, both as fixed cells in tissues like the liver, spleen, and lungs, as well as free-roaming phagocytic cells in the bloodstream. They play a crucial role in the immune response by engulfing and digesting harmful pathogens, damaged cells, and debris.

White blood cells attack and destroy tetanus bacteria by recognizing them as foreign invaders. They engulf the bacteria and release chemicals to kill them. Additionally, white blood cells can produce antibodies that specifically target tetanus toxins, neutralizing their harmful effects.

gene control and from the patterns of cellular control for gene product behavior, and play very important role in maintenance number of chromosome in the offsprings against the evaluation changes.

Reticulocytes are immature red blood cells that still contain some organelles, while erythrocytes are mature red blood cells that have lost their organelles and are responsible for oxygen transport. Reticulocytes are typically found in the bloodstream for a short period before maturing into erythrocytes.

Red blood cells contain hemoglobin, a protein that binds to oxygen. Hemoglobin has iron ions that attract oxygen molecules and form a reversible bond with them. This allows red blood cells to transport oxygen from the lungs to tissues throughout the body.
