BLOOD ANATOMY & PHYSIOLOGY Flashcards
Carrier of gases, nutrients, and waste products
BLOOD
enters blood in the lungs and is transported to cells
OXYGEN
produced by cells, is transported in the blood to the lungs, from which it is expelled
CARBON DIOXIDE
Clotting proteins help stem blood loss when a blood vessel is injured.
CLOT FORMATION
Most substances are produced in one part of the body and transported in the blood to another part.
TRANSPORT OF PROCESSED MOLECULES
Antibodies help protect the body from pathogens.
PROTECTION AGAINST FOREIGN SUBSTANCES
Various hormones and enzymes that regulate body processes are carried from one part of the body to another within the blood.
TRANSPORT OF REGULATORY MOLECULES
Warm blood is transported from the inside to the surface of the body, where heat is released from the blood.
MAINTENANCE OF BODY TEMPERATURE
an important blood buffer and contributes to the osmotic pressure of blood, which acts to keep water in the blood stream
ALBUMIN
color of oxygen-rich blood
SCARLET
color of oxygen-poor
DULL RED
TRUE OR FALSE:
Blood is thicker than water
TRUE
TRUE OR FALSE:
Water is thicker than blood
FALSE
how many times is blood thicker than water
FIVE TIMES
ph of blood
7.35 & 7.45
temperature of blood
38 degrees celsius
liquid part of the blood
PLASMA
how many % of water is plasma
90%
are the MOST ABUNDANT SOLUTES in plasma; except for antibodies and protein-based hormones, most ________ are made by the liver.
PLASMA PROTEINS
red blood cells, function primarily to ferry oxygen in blood to all cells of the body.
ERYTHROCYTES
an iron bearing protein, transports the bulk of oxygen that is carried in the blood.
HEMOGLOBIN
shape of red blood cells
CELL SHAPED LIKE BIOCONCAV DISCS
number of RBCs
5 million cells per cubic mm
normal blood
12-18 grams
white blood cells, are far less numerous than red blood cells, they are crucial to body defense against disease.
LEUKOCYTES
form a protective, movable army that helps defend the body against damage by bacteria, viruses, parasites, and tumorcells.
LEUKOCYTES
White blood cells are able to slip into and out of the blood vessels- a process called
DIAPEDESIS
In addition, WBCs can locate areas of tissue damage and infection in the body by responding to certain chemicals that diffuse from the damaged cells; this capability is called
POSITIVE CHEMOTAXIS
Once they have “caught the scent”, the WBCs move through the tissue spaces by ___________ (they form flowing cytoplasmic extensions that help move them along).
AMEBOID MOTION
A total WBC count above 11, 000 cells/mm3 is referred to as
LEUKOCYTOSIS
The opposite condition, is an abnormally low WBC count.
LEUKOPENIA
are granule-containing WBCs; they have lobed nuclei, which typically consist of several rounded nuclear areas connected by thin strands of nuclear material, and includesneutrophils,eosinophils, andbasophils.
GRANULOCYTES
are the most numerous of the WBCs
NEUTROPHILS
neutrophils are avid _________ ( a type of cell within the body capable of engulfing and absorbing bacteria and other small cells and particles) at sites of acute infection, and are particularly partial to bacteria and fungi.
PHAGOCYTES
have blue red nucleus that resembles an old-fashioned telephone; their number increases rapidly during allergies and infections by parasitic worms or entering via the skin.
EOSINOPHILS
the rarest of the WBCs, contain large, histamine-containing granules that stain dark blue; histamine is an inflammatory chemical that makes blood vessels leaky and attracts other WBCs to the inflammatory site.
BASOPHILS
