flow of blood through an artery

A capillary bed (made of numerous capillaries) has an arterial and venous end. Exchanges of nutrients, gases, and wastes between blood and interstitial space in opposite directions occur specifically at these so-called ends. Explain why amino acids leave the blood through the arterial end, and organic wastes enter it via the venous end?

the plasma protein not made by the liver is: A. Fibrinogen B. albumin C. low density lipoprotein D. Immunoglobulins

An infl ated catheter is used in balloon angioplasty to open up arteries that are occluded with plaque formation. Stents are placed in the arteries to support the arterial wall. Radioisotopes have been incorporated into the stents to inhibit the reclosing of the artery (called restenosis). Almost a half million patients in the United States receive intravascular therapy each year. (a) Research the current status of using radioisotopes in this process. How many patients are treated in the United States each year using it? (b) Which radioisotopes are primarily used? Are they beta or gamma emitters? Why would one be favored over the other?

The concentration of cholesterol in the blood serum of a normal adult is approximately 200 mg/dL. How many grams of cholesterol does a person with a blood volume of 5.75 L have circulating in his or her blood? (You may need to review Chapter 1.)

Which of the following options is correct for two visible differences between the maternal red blood cell and the foetal red blood cell? Maternal Red Blood Cell Foetal Red Blood Cell (A) Larger, enclosed by capillary Smaller, not enclosed by capillary (B) Smaller, not enclosed by capillary Larger, enclosed by capillary (C) Smaller, nucleus seen Larger, no nucleus seen (D) Larger, no nucleus seen Smaller, nucleus seen

Describe the nutrient and gas content of the blood flowing in the umbilical vein.  Is this the kind of blood you would expect to find in a vein?  Explain.  Is there another place in the body where a similar situation occurs?  If so, where?

An individual with______ would have an impaired ability to form blood clots because they would be unable to make sufficient quantities of both fibrinogen and the clotting factors. an iron deficiency liver failure megakaryocytes in their bone marrow insufficient cholesterol in their diet

Endurance athletes sometimes try an illegal method of blood doping called autologous transfusion. Some blood from the athlete is removed well before competition, and then transfused back into the athlete just before competition. (a) Why might blood transfusion benefit the athlete? (b) With time, stored red blood cells become depleted in 2,3-BPG. What might be the consequences of using such blood for a blood transfusion?

platelets globulins fibrinogen erythrocytes leukocytes connective plasma fibrinogen coagulation albumin men women formed elements Blood is a tissue that consists of formed elements and an extracellular matrix called The formed elements include red and white blood cells, and cell fragments called Plasma: The fibers of the extracellular matrix are actually fiber precursor molecules called Plasma consists of water, protein, nutrients, electrolytes, wastes, hormones, and gases. Plasma contains a multitude of proteins. However, three proteins predominate. contributes towards blood viscosity and helps transport lipophilic substances in the blood. , otherwise known as antibodies, help combat specific pathogens. Finally, upon activation, fibrinogen forms fibers during the process of are cells and cell fragments found in the blood. serve to transport gases in the blood. are blood cells of the immune system that combat pathogens. are cell fragments that assist in the process of blood clot…
