with 100% Correct Answers
BEGIN 17.1 - ✔✔BEGIN 17.1
Blood performs a number of functions, all concerned in one way or another
with what? - ✔✔Transporting substances, regulating blood levels of
particular substances, or protecting the body
Transport functions of blood - ✔✔- Delivering oxygen from the lungs and
nutrients from the digestive tract to all body cells
- Transporting metabolic waste products from cells to elimination sites (to
the lungs to eliminate carbon dioxide, and to the kidneys to dispose of
nitrogenous wastes in urine)
- Transporting hormones from the endocrine organs to their target organs
Regulatory functions of blood - ✔✔- Maintaining appropriate body
temperature by absorbing and distributing heat throughout the body and to
the skin surface to encourage heat loss
- Maintaining normal pH in body tissues. Many blood proteins and other
bloodborne solutes act as buffers to prevent excessive or abrupt changes

, in blood pH that could jeopardize normal cell activities. Blood also acts as
the reservoir for the body's "alkaline reserve" of bicarbonate ions
- Maintaining adequate fluid volume in the circulatory system. As we will
see, blood proteins prevent excessive fluid loss from the bloodstream into
the tissue spaces. As a result, the fluid volume in the blood vessels
remains ample to support efficient blood circulation to all parts of the body
Protection functions of blood - ✔✔- Preventing blood loss. When a blood
vessel is damaged, platelets and plasma proteins initiate clot formation,
halting blood loss
- Preventing infection: Drifting along in blood are antibodies, complement
proteins, and leukocytes (white blood cells), all of which help defend the
body against foreign invaders such as bacteria and viruses
END 17.1 - ✔✔END 17.1
BEGIN 17.2 - ✔✔BEGIN 17.2
Blood is the only ____ tissue in the body - ✔✔Fluid
What type of tissue is blood? - ✔✔Connective
Components of blood - ✔✔Blood is a specialized connective tissue in
which living blood cells, called the formed elements, are suspended in a
