Chapter 19: The Cardiovascular System: The Blood Flashcards
the fluid that circulates in the heart, arteries,
capillaries, and veins carrying nourishment and oxygen
to and bringing away waste products from all parts of
the body.
Blood
What are the three main functions of the blood
- Transportation.
- Regulation.
- Protection
What are the components of blood
- Blood plasma
- Formed elements
a. red blood cells
b. white blood cells
c. platelets
Red blood cells (RBCs) or ___________
transport oxygen from the lungs to body cells
and deliver carbon dioxide from body cells to
the lungs.
erythrocytes
Percentage of total blood
volume occupied by RBCs
HEMATOCRIT
also known as leukocytes
protect the body from invading pathogens and
other foreign substances.
White blood Cells
are fragments of cells that do not have a
nucleus
PLATELETS
Types of White Blood Cells
- GRANULAR
a. neutrophils
b. eosinophils
c. basophils
- AGRANULAR
a. lymphocytes
b. monocytes
s a sequence of responses that stops
bleeding.
HEMOSTASIS
Most cells of a multicellular organism cannot move
around to obtain oxygen and nutrients or eliminate
carbon dioxide and other wastes. Instead, these needs
are met by two fluids:
blood and interstitial fluid.
Blood
is a liquid connective tissue that consists of cells surrounded by a liquid extracellular matrix. The
extracellular matrix is called
blood plasma,
the fluid that bathes body cells and is constantly
renewed by the blood. B
Interstitial
fluid
White Blood Cell Function: Street Cop - rapid response
Neutrophil
White Blood Cell Function: Fumigator (kills parasite)
Eosinophil
