exam 4 lab Flashcards
Identifying Blood cells
Erythrocytes
- has a bi - concave shape which increases surface area and helps facilitate gas exchange
Identifying Blood cells
Neutrophils
Identification: multi-nucleated
Function: first responders to bacterial infections
Identifying Blood cells
Eosinphils
Identification: bi-lobed nucleus w/ red-orange granules
Function: fights off parasitic worms
Identifying Blood cells
Basophils
Identification: bi-lobed nucleus w/ blue-purple granules
Function: release histamine during inflammatory response
Identifying Blood cells
Monocyte
Identification: u-shaped nucleus
Function: phagocytize pathogens and debris as macrophages
Identifying Blood cells
Lymphocyte
Identification: large nucleus
Function: produces antibodies, kills tumor cells, control immune responses
Elavated number of leukocytes
Elavated number of Neutrophils
There is a bacterial infection
Elavated number of leukocytes
Elavated number of Eosinphils
There is a parasitic worm infection or allergic reaction
Elavated number of leukocytes
Elavated number of Basophils
There is generalized inflammation
Elavated number of leukocytes
Elavated number of Monocytes
There is a bacterial infection
Elavated number of leukocytes
Elavated number of Lymphocytes
The infection has been ongoing for at least a week, immune system activated
Blood typing
Agglutination
the clumping of RBC’s when the antibody present binds to its corresponding antigens
Blood typing
Determining blood type
- if agglutination happens in the serum that is the blood type.
- If the Rh group agglutinates it is (+), if it stays the same it is (-)
Blood typing
Mismatched Transfusion
person recieves the wrong blood type, leads to agglutination, causes blood cells to burst, this leads to clogged arties, potentially death
Blood typing
Why is the ABO & Rh system used?
they are important for transfusions because they are the main cause of agglutination
Blood smear
Sickle cell anemia
identification, causes, & symptoms
Identification: sickle-shaped erythrocytes
Cause: mutation in the hemaglobin beta gene
Symptoms: anemia, organ failure
Blood smear
Thalassemia
identification, causes, & symptoms
Identification: translucent blood cells due to lack of hemaglobin
Cause: inherited blood disorder, lack of hemagloblin in each RBC
Symptoms: fatigue, anemia
Blood smear
Myeloid leukemia (chronic)
identification, causes, & symptoms
Identification: an excessive amount of white blood cells in the blood
Cause: accumulation of mature white blood cells
Symptoms: Fatigue, frequent infections
Blood smear
Malaria (plasmodium)
identification, causes, & symptoms
Identification: shows circular forms within red blood cells
Cause: infection by plasmodium parasites
Symptoms: Fever, chills, anemia
Blood smear
What is a vector and what is the vector for Malaria
- a vector is a disease that is transmitted by another host organism
- the vector for malaria is a mosquito
Blood smear
What is the term for a disease
that can be transmitted
Communicable or infectious
Cardiac muscle tissue
Branching Network
term & purpose
Term: synticium
Purpose: forms a large network to distribute signals from one cell to the other
Cardiac muscle tissue
Intercalated discs
term & purpose
Term: Intercalated Discs
Purpose: allow passage of ions and contractile signals to distribute thoughout the heart tissue
