Anatomy and Physiology- Ch 11 HW
A sample of tissue from an injury shows a large number of eosinophils. This would indicate that the tissue was
infected by parasites
Following a major car accident, the patient is brought to the hospital after losing 3 liters of blood. To save the patient's life, the ER medical staff should transfuse what blood type?
O-
The least numerous white blood cells in peripheral circulation are the
basophils
The function of hemoglobin is to
bind and trasport oxygen and carbon dioxide
The primary function of red blood cells:
carry gases such as carbon dioxide and oxygen
Platelets are
cellular fragments
Other solutes: Essential for vital cellular activities
electrolytes
A drifting blood clot, air bubble, or fat globule is called
embolus
Formation of red blood cells is called
erythropoiesis
Fibrinogen:
functions in clotting and normally accounts for roughly 4% of plasma proteins
Neutropils, eosinophils, and basophils are all ___________.
granulocytes
The percentage of whole blood volume occupied by formed elements is called
hematocrit
The mechanism in the body which stops bleeding and prevents blood loss is known as ___________.
hemostasis
Formed elements that are nucleated and capable of amoeboid movement are
leukocytes
Which organ synthesizes more than 90 percent of plasma proteins?
liver
When foreign cells invade the body, one would most likely expect to see increased numbers of
lymphocytes
Globulins:
make up for about 35% of the proteins in the plasma.
Albumins:
make up roughly about 60% of the plasma proteins
Which of the following is an agranulocyte?
monocyte
The most abundant type of WBC in a normal blood sample is the ___________.
neutrophil
Which of the following are the most active type of leukocytes, phagocytically, and are usually the first to arrive at an injury site?
neutrophils
Which of the following Paris are mismatched?
neutrophils: antibody production
EPO is released when
oxygen levels in the blood decrease
Thrombocytopenia is defined as a deficiency of
platelets
Which of the following initiate the clotting process and help close injured blood vessels?
platelets
The three types of formed elements found in blood are __________.
platelets, red blood cells, and white blood cells
What is the chief difference between plasma and serum?
presence/absence of clotting proteins
Calcium ions and ________ have an effect on nearly every aspect of the clotting process.
vitamin K
The following is a list of the steps involved in the process of hemostasis and clot removal: 1. coagulation phase 2. fibrinolysis 3. vascular phase 4. retraction 5. platelet phase The correct sequence of these steps is
3, 5, 1, 4, 2
The average life span of a red blood cell is about
4 months
________ is the characteristic of WBCs that allow them to enter surrounding tissue by squeezing between adjacent epithelial cells in the capillary wall.
Diapedesis
Leukocytes:
Neutophil, Eosionophil, Basohil, Monocyte, Lymphocyte
Electrolytes:
The major plasma electrolytes are Na+, K+, Ca^2+, Mg^2+, Cl-, HCO3-,HPO4- and SO4^2-
What is a benefit of a vascular spasm at the onset of hemostasis?
a reduction in blood loss
Plasma proteins that are necessary for blood to maintain osmotic pressure are
albumins
Which leukocytes would you expect to increase in response to a parasitic infection?
eosinophils
White blood cells:
eosinophils, neutrophils, basophils, lymphocytes, monocytes
___________ are large phagocytic WBC's that remain in circulation for only about 24 hours before entering peripheral tissues to become tissue macrophages
Monocytes
Which of the following statements is true regarding the blood of an individual with Type AB?
Type AB blood does not contain anti-A or anti-B antibodies
During blood transfusions, which of the following blood types would NEVER cause an agglutination reaction when introduced into an individual with Type A+ blood?
Type O- blood
Organic wastes:
Waste products are carried to sites of breakdown or excretion. Ex: urea, uric acid, creatinine, bilirubin, ammonium ions
Other solutes: carried to sites of breakdown or excretion
Organic wastes
In adults, the stem cells responsible for the production of red and white blood cells originate in the
red bone marrow
