Which statement about erythrocytes is false

There are other organs and systems in our bodies that help regulate blood cells. The lymph nodes, spleen, and liver help regulate the production, destruction, and function of cells. The production and development of new cells in the bone marrow is a process called hematopoiesis. Blood cells formed in the bone marrow start out as stem cells. A stem cell or hematopoietic stem cell is the first phase of all blood cells.

As the stem cell matures, several distinct cells evolve. These include red blood cells, white blood cells, and platelets. Immature blood cells are also called blasts. Some blasts stay in the marrow to mature.

Others travel to other parts of the body to develop into mature, functioning blood cells. The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs.

Hemoglobin Hgb is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body. The main job of white blood cells, or leukocytes, is to fight infection. There are several types of white blood cells and each has its own role in fighting bacterial, viral, fungal, and parasitic infections. Types of white blood cells that are most important for helping protect the body from infection and foreign cells include the following:.

Help heal wounds not only by fighting infection but also by ingesting matter, such as dead cells, tissue debris, and old red blood cells. The main job of platelets, or thrombocytes, is blood clotting. Platelets are much smaller in size than the other blood cells. They group together to form clumps, or a plug, in the hole of a vessel to stop bleeding. Study Materials. Why use Doubtnut? Instant Video Solutions. Request OTP.
