Transportation in Human Beings Video Lecture - Class 10

transportation in human beings hello
students in our previous section we have
about nutrition and respiration now let
us discuss about transporting human
beings and transporting plants as we've
learned earlier blood transports food
oxygen and salt takes away waste
materials from our body blood is a fluid
connective tissue in Luud medium in
blood is cold as plasma in which cells
are suspended the plasma in the blood
helps in transportation of food oxygen
carbon dioxide and nitrogen as wastes in
dissolved form the oxygen in the blood
is carried by red blood cells to perform
all the functions of circulation a
pumping organ called heart it is present
in human body which consists of network
of tubes to reach all the tissue of the
system let us discuss about heart in
detail heart is a muscular organ which
is conical in shape it sizes as a fist
and located on the left side of the
chest let us discuss about structure of
heart in detail structure of heart the
heart is divided into four chambers one
right upper chamber two right lower
chamber three left upper chamber four
left lower chamber upper chambers of the
heart are called as Oracle's or atrium
lower chambers of the heart are called
as ventricles ventricles have thicker
muscles than Oracle's to prevent
backward flow of blood voles are present
between Oracle's and ventricles the
blood in the body is differentiated into
two types of rich contents oxygen rich
content blood is called as oxygenated
blood
carbon dioxide rich content blood is
called as deoxygenated blood to prevent
both types of blood mixing in the heart
heart is divided into chambers
oxygenated blood which is oxygen rich
content reaches from lungs to heart and
distributed the rest of the parts of the
body deoxygenated blood which is carbon
rich content collected from all parts of
the body to heart for purification
