Question

1. An 85 year old white woman is hit by a car while crossing the street and suffers many serious injuries. She is suspected to be homeless, and the only belongings she has are empty liquor bottles. At the hospital, it is discovered that she is severely anemic. List all the factors you can think of that may contribute to her anemia. 2. In ventricular systole, the right ventricle is the first to expel blood, but the left ventricle is the first to begin contracting. Aside from the obvious fact that the pulmonary valve opens before the aortic valve, how can you explain this difference? 3. Explain how coagulation differs from agglutination.

Answer 1

1. List all the factors you can think of that may contribute to her anemia. Anemia Causes:

Causes for anemia for this client may incorporate the following:

• Anemia from dynamic dying: Loss of blood through serious wounds
• Anemia identified with poor nourishment:

• Vitamins and minerals are required to make red platelets. Notwithstanding iron, vitamin B12 and folate (or folic corrosive) are required for the correct generation of hemoglobin (Hgb).
• Deficiency in any of these may cause weakness as a result of deficient creation of red platelets.
• Poor dietary admission is a vital reason for low folate and low vitamin B12 levels.
• Strict vegans who don't go for broke adequate vitamins are in danger to create vitamin B12 insufficiency.

2. In ventricular systole, the right ventricle is the first to expel blood, but the left ventricle is the first to begin contracting. Aside from the obvious fact that the pulmonary valve opens before the aortic valve, how can you explain this difference?

The after load in the aspiratory trunk is much lower than the afterload in the aorta, so the pneumonic valve does not need to overcome as much protection as the aortic valve. This is the reason the pneumonic valve opens first and blood is ousted from the correct ventricle somewhat sooner than from the left ventricle.

3. Explain how coagulation differs from agglutination.

Agglutination and coagulation are two extremely specialized terms which seldom come up unless you are a therapeutic expert. These two terms allude to two unique marvels; in any case, agglutination makes just a minor part in the coagulation course.

Agglutination

Agglutination is the way toward clustering of particles. There are numerous cases of agglutination. Hemagglutination is the meeting up of red platelets. Leukoagglutination is the clustering of white platelets. Bacterial antigens agglutinate with antibodies making finding less demanding. Blood gathering is another basic illustration where agglutination is utilized to make a determination. There are unpredictable instruments behind these particles meeting up and shaping a bunch.

Cells have receptors on their surfaces. These receptors tie with specific atoms outside the cells. Blood gathering is a decent illustration that can be utilized to clarify this basically. There are four noteworthy blood classifications. They are A, B, AB and O. A, B and AB allude to the nearness of particular antigens (An antigen, B antigen) on red cell surfaces. O implies that there is neither An or B antigen on red cell surfaces. On the off chance that An antigen is there on the red cell surfaces, hostile to An immune response isn't there in plasma. B blood amass has hostile to An antibodies in plasma. Abdominal muscle blood assemble does not have either. O blood aggregate has both An and B antibodies. An antigen ties with An immune response. At the point when B blood is blended with A blood, because of the nearness of against An antibodies in plasma, red cells tie with these antibodies. More than one red cell tie with one neutralizer, so there is a cross linking; this is the premise of red cells meeting up. This is the premise of clustering.

Coagulation

Coagulation is the procedure of blood thickening. Thickening has three noteworthy advances. They are platelet plug arrangement, natural or extraneous pathways, and the regular pathway. Injury to platelets and endothelial cells covering the veins discharges chemicals, which actuate and total platelets. Injury to cells discharges histamine first. At that point other fiery middle person like serotonin, real essential proteins, prostaglandin, prostacyclin, leukotrienes, and platelet acting variable become possibly the most important factor. Because of these chemicals, there is an agglutination of platelets. The final product is the development of the platelet plug.

Presentation of responsive extracellular grid material triggers two chain responses, specifically the extraneous and inherent pathways. These two pathways end by actuating factor X. Factor X enactment is the underlying advance of the normal pathway. The normal pathway prompts the arrangement of a fibrin work, on which platelets get caught, and a conclusive coagulation is framed.

Certain maladies influence coagulation. Hemophilia is where an absence of coagulation factors prompts poor thickening and over the top dying. Irregular coagulating and improper thickening lead to decimating conditions like strokes and myocardial localized necrosis.

What is the difference between Agglutination and Coagulation?

• Agglutination implies the meeting up of particles while coagulation implies the arrangement of a complete blood clump.
• Many particles can agglutinate while no one but blood can coagulate.
• Agglutination is because of an antigen-counter acting agent response while coagulation is because of actuation of numerous plasma factors.
