Overview of Blood
These are the three main functions of the blood.
What are transportation, defense, and maintenance of homeostasis?
The production of blood cells and platelets
What is hemopoiesis?
This protein gives red blood cells their color
What is hemoglobin?
The common name for a leukocyte
What is a white blood cell?
The name for excessive bleeding that will occur if hemostasis fails.
These are the TWO main elements that blood is made of.
What are formed and fluid elements?
Hemopoiesis occurs in these structures in our body, such as the proximal epiphyses.
What are bones?
This type of shape gives the red blood cell more surface area, allowing for the absorption of more oxygen.
What is biconcave?
When a white blood cell squeezes through cells in a blood vessel wall in order to get from the blood stream to a tissue.
What is emigration?
The formation of a blood clot
What is coagulation?
The pH of blood
What is 7.4?
Stem cells are classified by their ability to diversify. A hemopoietic stem cell is this type of stem cell.
What is a multipotent stem cell?
After a red blood cell has lived out its roughly 120 day lifespan, it goes to these two organs to be broken down.
What are the liver and the spleen?
Leukocytes are classified into these TWO categories.
What are granular and agranular?
When the wall of a vessel is damaged, the smooth muscle in the walls of the vessel contract dramatically, also known as this.
What is a vascular spasm?
When performing a hematocrit test, a centrifuge separates the blood into these three parts.
What is plasma, buffy coat, hematocrit (RBCs)
Lymphoid stem cells diversify into lymphocytes. Myeloid stem cells diversify into monocytes, granular leukocytes, and this type of formed element.
What are platelets?
These types of cells break down red blood cells that are at the end of their life cycle.
What are macrophages?
Another name for a platelet
A thrombus is a clot that obstructs blood flow and results in dead tissue. This is a clot that has broken free, travels to, and lodges in another part of the body
What is an embolus?
Plasma contains 92% water, albumin, globulins, and these plasma proteins that play an essential role in blood clotting.
What is fibrinogen?
During this section we watched a video about Erythropoiesis (EPO) which is another term for this enhancement for athletes and a treatment for blood disorders such as anemia.
What is blood doping?
Trace elements help contribute to the synthesis of hemoglobin. Name one of them.
What are iron, copper, zinc, and B Vitamins?
The two purposes of platelets are that they help in homeostasis by stopping blood flow due to injury, and this function, that is essential for growth and repair of tissue.
What is secrete growth factors?
This is an important process that restores normal blood flow by gradual degradation of the clot.
What is fibrinolysis?
