Blood quiz/assignment
Each heme can carry ____ molecule of oxygen
4
Formed elements make up about what percentage of blood?
45 percent
when oxygen molecules have diffused from the hemoglobin to the tissues and cells that need oxygen
Deoxyhemoglobin
Platelets stick to where the tear is The aggregation causes a platelet plug because the platelets are sticking together This closes off the tear Platelets release clotting compounds such as serotonin, calcium ions, adenosine diphosphate Chemicals limit the platelet plug so it breaks off and doesn't grow and cause issues
Platelet phase
when oxygen molecules are attached to hemoglobin
Oxyhemoglobin
clotting factors. Required for normal clotting. Proteins or ions in plasma.
Procoagulants
when red blood cells stack together (aggregate) to get to distal tissues
Rouleaux
Why does blood have a high viscosity compared to water
The formed elements
The most abundant proteins in blood plasma are
albumins.
Which of these is not one of the formed elements of blood?
antibodies
White blood cells that release histamine at the site of an injury are
basophils.
Red blood cell production is regulated by the hormone
erythropoietin.
All of the following are true of neutrophils, except that they are phagocytic. important in coagulation. active in fighting bacterial infections. also known as polymorphonuclear leukocytes. granular leukocytes.
important in coagulation.
Which organ secretes most of the plasma proteins?
liver
The most numerous white blood cells in peripheral circulation are the
neutrophils.
Which of these descriptions best matches the term B lymphocytes? produce antibodies in response to antigens kill bacteria using hydrogen peroxide helper cells are one type adhere to collagen beneath endothelium often elevated in allergic individuals
produce antibodies in response to antigens
Most of the cells are made in
red bone marrow (myeloid stem cells in tissue).
People with type AB blood are considered the "universal recipient" for transfusions because
their blood lacks A or B agglutinins.
Which of the following vitamins is needed for the formation of clotting factors?
vitamin K
The most abundant component of plasma is
water.
low охуgen
Нурохiа
Compare and contrast myeloid stem cells and lymphoid stem cells
•Compare: both myeloid and lymphoid stem calls undergo the process of hemopoiesis to form blood cells. Both produce the "formed elements" •Contrast: Myeloid tissue produces RBCS and all other WBCS except lymphocytes. Lymphoid stem cells produce lymphocytes, a type of WBC.
the clumping of antigens and opposing antibodies (will hemolyze)
Agglutination
Which of the following is a function of the blood? defense against toxins and pathogens transport of body heat transport of nutrients and wastes transport of gases
All of the answers are correct.
a condition in which the oxygen-carrying capacity of the blood is reduced.
Anemia
Bill wants to determine his blood type, so he takes a few drops of blood from a puncture wound in his finger and mixes it with various antisera. His blood cells agglutinate when mixed with the anti-A sera but not with the anti-B or anti-D sera. This means
Bill's plasma contains B antibodies.
when carbon dioxide binds to hemoglobin and is carried to the lungs
Carbaminohemoglobin
movement toward a certain chemical (WBCS moving through blood vessel walls, out of bloodstream, and to damaged tissue in response to the specific chemical secreted.)
Chemotaxis
blood clotting. Last phase of hemostasis. Seals the tear off to stop the bleeding and mesh is created for repair.
Coagulation
- The tear seals off with fibrinogen and fibrin - This creates a mesh that allows for repair.
Coagulation phase
What drives the production of blood cells
Colony-stimulatinf factors (CSFs)
Hemoglobin is found it what type of cell
Erythocyte
the formation of stem cells maturing to become red blood cells. Occurs only in myeloid tissue (red bone marrow).
Erythropoiesis
whole red blood cells in the urine caused by kidney or tissue damage.
Hematuria
hemoglobin is in the urine due to too much red blood cell hemolysis
Hemoglobinuria
breaking down and tearing apart of red blood cells. The RBC's are engulfed by macrophages and the iron and protein are recycled. Waste exits the body through urine.
Hemolyze
formation of formed elements (blood cells).
Hemopoiesis
Which of the following statements about blood is false? The normal pH of blood is 6,8 to 7.0. Blood contains buffers that control pH. Blood is more viscous than water. Cells in blood comprise the formed elements. Blood is about 55 percent plasma.
The normal pH of blood is 6.8 to 7.0.
A spasm of the endothelial cells of the blood vessel wall occurs. Chemical factors such as ADP, prostacyclin, tissue factors, and the hormone endothelins are released. This stimulates the accumulation of platelets (sticky clotting).
Vascular phase
The function of hemoglobin is to
carry dissolved blood gases.
The function of red blood cells is to
carry oxygen to the cells and then carry away carbon dioxide.
Platelets are
cytoplasmic fragments of large cells.
White blood cells that are increased in allergic individuals are the
eosinophils.
