Question 1

_____________ perform phagocytosis,especially when out of the blood and in tissues.

Accepted Answer

Monocytes are known for performing phagocytosis when they are out of the blood and in tissues. Neutrophils also perform phagocytosis, but they are found in greater numbers in the blood than in tissues. Lymphocytes, eosinophils, and basophils do not perform phagocytosis.

Question 2

Normally,the volume of the blood plasma

Accepted Answer

The volume of blood plasma remains fairly constant as the intake and loss of water through various routes stay roughly equal. This is due to the homeostatic mechanisms in the body that regulate the balance of fluids and electrolytes. Therefore, options B, C, D, and E are incorrect.

Question 3

An 8-year old boy has periodic trouble breathing.A complete blood count is performed on the boy to determine if he has stress-anxiety syndrome or asthma (an allergic reaction).With which type(s)of white blood cells should you be most concerned?

Accepted Answer

E

Question 4

Plasma proteins

Accepted Answer

Plasma proteins include albumin, globulins, and fibrinogen, and are a major factor in determining osmotic pressure of blood. Some plasma proteins, such as fibrinogen, are responsible for clot formation. Additionally, plasma proteins include antibodies and many other chemicals that function in immunity. Therefore, all of these properties apply to plasma proteins.

Question 5

Globulins in the plasma

Accepted Answer

Globulins in the plasma function as transport molecules and clotting factors.

Question 6

Serum

Accepted Answer

Serum is blood plasma without the clotting factors.

Question 7

The white blood cells called granulocytes are

Accepted Answer

Granulocytes are a type of white blood cell characterized by the presence of granules in their cytoplasm. The three types of granulocytes are neutrophils, basophils, and eosinophils. Choice A is incorrect because red blood cells, thrombocytes, and megakaryoblasts are not types of granulocytes. Choice B is incorrect because monocytes and macrophages are not types of granulocytes. Choice D is incorrect because lymphocytes and monocytes are not all types of granulocytes. Choice E is incorrect because thrombocytes, monocytes, and macrophages are not types of granulocytes.

Question 8

___________ are the most common leukocytes and their dead cells are part of pus.

Accepted Answer

Neutrophils are the most common leukocytes and their dead cells are part of pus.

Question 9

Erythropoietin

Accepted Answer

Erythropoietin stimulates red bone marrow to produce more red blood cells. It does not require vitamin B12 as a cofactor, is not produced in the intestines, and is actually produced when low blood oxygen levels occur. Therefore, choices A, B, and D are incorrect.

Question 10

What is the function of water in the plasma?

Accepted Answer

Water in the plasma acts as a solvent and suspending medium for blood components such as red and white blood cells, platelets, and proteins.

Question 11

________________ release histamine and heparin.

Accepted Answer

Basophils are a type of white blood cell that are involved in allergic reactions and release chemicals such as histamine and heparin, which contribute to the inflammatory response.

Question 12

Red blood cells

Accepted Answer

Red blood cells contain large quantities of hemoglobin, which is what allows them to carry oxygen throughout the body. They are not biconvex disks, do not have several nuclei in each cell, and do not divide frequently.

Question 13

Which of the following constituents of the blood plasma help to maintain the osmotic pressure of the blood?

Accepted Answer

Albumin and sodium chloride are the constituents of the blood plasma that help to maintain the osmotic pressure of the blood. Albumin is the most abundant plasma protein, and it helps to regulate the movement of water between the blood and the tissues. Sodium chloride, on the other hand, helps to maintain the electrolyte balance in the blood, which is critical for maintaining the osmotic pressure. Dissolved waste products and nutrients are not directly involved in maintaining the osmotic pressure of the blood.

Question 14

________________ are involved in the destruction of worm parasites.

Accepted Answer

Eosinophils are white blood cells that are primarily involved in the destruction of parasitic worms. They do this by releasing granules that contain various enzymes and toxins which damage the parasite's surface, leading to its death. Neutrophils and monocytes are also involved in the immune response to parasites, but they play a more general role in fighting infections. Lymphocytes and basophils play a role in the immune response but are not specifically involved in fighting parasitic infections.

Question 15

__________________ are the largest of the leukocytes.

Accepted Answer

Monocytes are the largest of the leukocytes and are characterized by their single, large kidney-shaped nucleus. They play a key role in the immune response by differentiating into macrophages and engulfing and digesting pathogens and cellular debris. Neutrophils, eosinophils, basophils, and lymphocytes are all smaller than monocytes.

Question 16

In contrast to red blood cells,leukocytes

Accepted Answer

Leukocytes, also known as white blood cells, are larger than red blood cells and have a nucleus. Unlike red blood cells, leukocytes are able to leave the bloodstream and move through the body's tissues by amoeboid movement to fight infection and foreign substances. Leukocytes do not contain hemoglobin and therefore do not have iron in the same way that red blood cells do.

Question 17

Red blood cell production

Accepted Answer

Red blood cell production occurs from cells called proerythroblasts and is stimulated by erythropoietin. Other factors that help in the production of red blood cells include iron, vitamin B12, and folic acid. Oxygen levels in the blood indirectly affect red blood cell production by regulating the release of erythropoietin.

Question 18

The major component of plasma is

Accepted Answer

The answer of The major component of plasma is
...

Question 19

Blood

Accepted Answer

Blood has a total volume of approximately 5 liters in the average human body. None of the other options accurately describe blood.

Question 20

Which of these leukocytes is NOT correctly matched with its function or description?

Accepted Answer

Basophils are a type of white blood cell that release histamine and other chemicals that contribute to inflammation and allergic reactions. They do not synthesize or produce antibodies. That role is primarily performed by B lymphocytes.
