The Circulatory System is manifested by the Astral Body
in the physical body. The Circulatory System is the energy pathway of fluids
in the body. The circulatory system is made up of the Cardiovascular system
and the Lymphatic System.
The Cardiovascular
System
-
The arteries- carry nutrient- rich, oxygenated blood from the heart to
capillaries which nourish the tissues in all parts of the body. Venules
take blood from the capillaries to the veins.
-
The veins carry the blood on its return journey to the heart.
-
The kidneys filter the blood and eliminate waste products into the urine
which goes to the urinary bladder where it is stored and then expelled
through the urethra. The kidneys regulate the plasma volume in the blood,
the concentration of waste products in the bloodstream, the pH of
the blood and the levels of electrolytes, (acids, bases and salts), in
the blood. One function of electrolytes is that they carry electrical current
in the body. The kidneys return water, electrolytes, glucose and other
vital substances to the blood in correct proportions to keep the blood
stable.
-
The blood transports oxygen from the lungs, nutrients from the digestive
system and hormones from the endocrine system to all the cells and tissues
in the body. The blood carries carbon dioxide from the cell tissues back
to the lungs for expulsion. The blood also carries waste products from
the cells and tissues to the excretory organs. Blood helps regulates pH
balance, interstitial fluid balance (fluid in between cells) as well as
maintain body temperature. The blood also contains a clotting mechanism
as well as immune system components. Blood is made up of three kinds of
cells which are suspended in a fluid called plasma.
-
Red blood cells or erythrocytes transport oxygen and carbon dioxide and
are formed in the bone marrow.
-
White blood cells or leukocytes destroy dead cells, produce antibodies
that fight viruses, detoxify foreign materials, and eat bacteria. They
are produced in the bone marrow, the thymus, the lymph nodes, various other
parts of the lymph system, the spleen and tonsils.
-
Platelets are cells that cause clotting of the blood when a blood vessel
has been damaged or cut and blood is escaping.
-
Plasma makes up a little over half of the blood. Plasma is about ninety
percent water. It contain thousands of substances such as vitamins, minerals,
glucose, electrolytes, hormones, antibodies and waste products. Because
of plasma, blood and the materials it carries flows freely to all parts
of the body.
-
The Heart - is the pump of the cardiovascular system. Electrical impulses
stimulate the pumping of the heart. The heart pumps the nutrient rich,
oxygen- depleted blood to the lungs where it releases carbon dioxide and
picks up oxygen and returns to the heart. From the heart it is then
pumped in two directions, upward and downward. The upward route goes to
the upper chest, arms, neck, head and brain and then returns to the heart
through the venus system. The downward route goes to the liver, spleen,
stomach, kidneys, small intestines the pelvic area and the legs. All the
blood that goes to the spleen, stomach, small intestines, and large intestines
then goes to the liver through the portal vein. All the nutrients obtained
from the digestive system are carried in the blood to the liver for final
processing before the blood returns to the heart through the venus system.
The blood going to the kidneys is filtered by the kidneys and returned
through the venus system to the heart. The rest of the blood going to the
lower body and legs returns to the heart via the venus system.
-
The pericardium is a fluid filled sack around the heart reduces friction
and keeps the heart from rubbing against the chest wall.
The Lymphatic System
The Lymphatic System has two main functions: the balance of body fluid
and immunity. As blood flows through the capillaries, dissolved materials
and fluid seep through the capillary walls into the intercellular space
of the tissues. Most of the fluid is returned to the capillaries but some
remains in the intercellular space. When this fluid enters the lymphatic
capillaries it is then called lymph.
The lymph travels in a one way direction through the lymphatic capillaries
then through the lymphatic vessels and lymph nodes. The lymphatic vessels
that drain the right arm , the right side of the head, neck, thorax, lung,
heart and liver flow into the right lymphatic duct. The right lymphatic
duct drains into the bloodstream through the right subclavian vein where
it joins the right jugular vein.
The rest of the lymph from left arm, left side of the head, neck, thorax,
lung, heart and the entire lower part of the body including the legs drain
into the thoracic duct. The thoracic duct drains into the bloodstream through
the left subclavian vein where it joins the left jugular vein.
The processed lymph that enters the bloodstream through the right and
left subclavian veins then flows into the superior vena cava which goes
to the right atrium of the heart.
The lymphatic system has no pump to move the lymph through the system.
The movement of lymph is promoted by many factors. The constant pressure
exerted by new fluid that is continually entering the intercellular space,
the pressure from expansion and contraction of nearby arteries, pressure
from the expansion and contraction of the lungs and the very important
pressure from the expansion and contraction of muscles during exercise
all work together to move the lymph through the lymphatic system.
Lymph comes from blood plasma, but it is clearer and more watery. Lymph
contains many substances such as fats, fat soluble vitamins, macrophages
(scavenger cells), and lymphocytes (white blood cells) and waste. Before
it reaches the bloodstream, the lymph is filtered by the lymph nodes of
most of its waste, bacteria and other harmful substances . The remaining
wastes are filtered out and eliminated by the kidneys.
The tonsils, the spleen and the thymus are organs of the lymphatic system.
The body is protected from harmful substances that enter the nose and mouth
by the tonsils. The spleen filters the blood and produces white blood cells
that clear up debris, destroy old blood cells and harmful substances.
The spleen also serves as a reserve blood supply. The thymus is responsible
for the development of the immune system and lymphocytes (T- cells) that
protect the body tissues.
The Sense of Touch
Sensory receptors convert stimulus into nerve impulses which
are interpreted as sensation by the central nervous system. Nerve impulses
may trigger a reflex response. Sensory receptors are located on the body
surface or skin, within muscles, joints, organs and body systems. They
are sensitive to vibrations, pressure, touch, temperature, stretch, tickle,
itch, pleasure and pain. There are many sensory receptors in the skin which
is the organ of touch.
The Skin is the largest organ of the body. Skin tissue, nerve endings,
blood vessels, hair, nails, and sweat glands are all part of the Integumentary
System or "covering." The skin protects the body, makes possible
sensations of the environment, helps regulate body temperature, excretes
waste, and manufactures vitamin D. The skin not only covers the body on
the outside, it also protects the eyes, lines the inside ears, nose, mouth
and digestive system.
