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.
