In Order Phagocytosis is a process whereby an antigen is engulfed, digested and disintegrated by a phagocytic cell
1 The process starts by the antigen coming in contact with the phagocytic cell 2 Phagocyte-antigen adherence takes place 3 The antigen enters the phagocytic cell, after which the antigen is engulfed forming a phagosome. The phagosome and lysosome form phagolysosome 4 Digestion of the antigen 5 Remains of the digestion process are expelled out of the cell in the form of debris
In the correct order 3 stages of hemostasis When a blood vessel is injured, the injury initiates a series of changes in three stage:
1 Vasoconstriction 2 Platelet plug formation 3 Coagulation of Blood
The average life span of RBC is about
120 days
Each hemoglobin molecule can hold up to _________ oxygen molecules.
4
The normal range of RBC for women is from
4.2 to 5.4 million cells/microliter
The normal range of RBC for men is approximately
4.7 to 6.1 million cells/microliter
Increase in number of WBCs indicate all the following except
Any condition that affects the nervous system of the human body
Red blood cells are also known as
Erythrocytes
True or False Proportion of Blood The plasma in the blood is on an average about 80% of the blood, and the formed elements form the remaining 20% of the blood
False
True or False The white blood cells are the major portion of the formed elements
False
True or False Study of the body functions is known as Anatomy
False, Study of the body functions is known as Physiology
True or False Study of the body structure is known as Physiology
False, Study of the body structure is known as Anatomy
Hemoglobin is a combination of
IRON (heme) and PROTEIN (globin)
White Blood cells are also known as
Leukocytes
Monocytes
Performs the function of phagocytes by the process of phagocytosis, however, they are less phagocytic in nature than the neutrophils. They help other white blood cells in recognizing the pathogens.
Thrombocytes
Platelets
Eosinophils
Provide immune response against parasitic infection. They are also seen in response to an allergic reaction.
Neutrophils
Provides immunity by protecting the body against bacteria and fungi. They are phagocytic in nature
Erthrocytes
Red Blood Cells
Basophils
Releases heparin and histamine. Heparin inhibits coagulation (clotting) making it possible for the other white blood cells to flow and Histamine cause vasodilation for increasing the blood flow to the area.
B & T Lymphocytes
They are of 3 types: T cells, B cells, and Natural killer cells. T cells provide immunity by the release of cells such as phagocytes and proteins such as cytokines etc. B cells provide immunity by producing antibodies. Natural killer cells are activated in response...
The platelets are present in fragments; their main function is to seal the injured blood vessel
Thrombocytes
True or False Blood has the ground substance, plasma. it also has fibers that are proteins that assists in clotting of blood and the cells are the formed elements.
True
True or False The constituents of the blood also differ depending on whether the blood is in the arterial system or the venous system. If the blood is in the arterial system, it mainly consists of oxygenated blood which simply means blood that contains oxygen, while the blood in the venous system mainly consists of deoxygenated blood which simply means blood that contains carbon dioxide
True
True or False Connective tissue has the following characteristics: 1 Ground Substance 2 Fibers 3 Cells
True
True or False Platelets is one of the constituents of the formed elements. Their main function is to clot blood. They are colorless cells within the human blood. They are present in fragments. Platelets also known as thrombocytes.
True
True or False Proportion of Blood From the 45% of the formed elements, less than 1% is the White Blood Cells and the Platelets, whereas the rest is the Red Blood Cells
True
True or False The blood is a type of connective tissue
True
True or False The blood is mainly red in color and differs in volume due to factor such as gender, age, weight, and etc. The volume of blood is usually higher in males.
True
True or False The vital function of the blood cells mainly the red blood cells is to carry oxygen and other constituents required by the tissues and on the other hand collect carbon dioxide and waste materials from the tissues and the vital functions of the white blood cells is to protect the body.
True
WBC 1 Neutrophils 2 Eosinophils 3 Basophils 4 Monocytes 5 B & T Lymphocytes
Type 1 Granulocyte 2 Granulocyte 3 Granulocyte 4 Agranulocyte 5 Agranulocyte
Leukocytes
White Blood Cells
Cytes means
cells
Deoxyhemoglobin
has higher compatibility for carbon dioxide than oxygen
Oxyhemoglobin
has higher compatibility for oxygen than carbon dioxide
RBC's are red due to the iron content of the
hemoglobin
Erythr- means
the color red
Leuk means
the color white
