Cardiovascular
Cardiovascular system- filled with blood. Contains the heart and the blood vessels.
Lymphatic system is a complex network of lymphoid organs, lymph nodes, lymph ducts,
lymphatic tissues, lymph capillaries and lymph vessels that produce and transport lymph fluid
from tissues to the circulatory system. The lymphatic system is a major part of the immune
system.
The lymphatic system has three interrelated functions: (1) removal of excess fluids
from body tissues, (2) absorption of fatty acids and subsequent transport of fat, as chyle, to the
circulatory system and, (3) production of immune cells such as lymphocytes (e.g. antibody
producing plasma cells) and monocytes.
Тhrombus, or blood clot, is the final product of the blood coagulation step in hemostasis. It
is achieved via the aggregation of platelets that form a platelet plug, and the activation of the
humoral coagulation system (i.e. clotting factors). A thrombus is physiologic in cases of
injury, but pathologic in case of thrombosis.
Blood
Blood scutums- small coreless cells. Their function is to curdle the blood.
Red blood cells are the most common type of blood cell and the vertebrate body's principal
means of delivering oxygen from the lungs or gills to body tissues via the blood.
White blood cells- they have various sizes and cores with various forms. Their main function
is to protect the body.
Functioning
Pulse-the throbbing of their arteries as an effect of the heart beat.
Regulation of hormones- it’s done by some hormones and minerals, made in the exchange of
materials.
Heart
Аorta- the largest artery in the human body, originating from the left ventricle of the heart
and bringing oxygenated blood to all parts of the body in the systemic circulation.
Arterial blood- blood rich in oxygen
Arterial pressure- the pressure made of the blood over the walls of the arteries.
Arteries- muscular blood vessels that carry blood away from the heart. All arteries, with the
exception of the pulmonary and umbilical arteries, carry oxygenated blood.
Endocarditis is an inflammation of the inner layer of the heart, the endocardium. The most
common structures involved are the heart valves.
Heart is a muscular organ responsible for pumping blood through the blood vessels by
repeated, rhythmic contractions, or a similar structure in the annelids, mollusks, and
arthropods.
Мyocarditis is inflammation of the myocardium, the muscular part of the heart. It is
generally due to infection (viral or bacterial). It may present with chest pain, rapid signs of
heart failure, or sudden death.
Vein - blood vessel that carries blood toward the heart. The majority of veins in the body
carry low-oxygen blood from the tissues back to the heart; the exceptions being the
pulmonary and umbilical veins which both carry oxygenated blood.
Vein blood- blood rich in CO2.
Imunsystem
Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS
or Aids) is a collection of symptoms and infections resulting from the specific damage to the
immune system caused by the human immunodeficiency virus (HIV) in humans, and similar
viruses in other species (SIV, FIV, etc.). The late stage of the condition leaves individuals
susceptible to opportunistic infections and tumors.
Artficially acquired immunity- immunity made by a vaccine.
Infections- diseases caused by microorganismes(like plague, cholera etc.)
Тonsils- areas of lymphoid tissue on either side of the throat. An infection of the tonsils is
called tonsillitis. Most commonly, the term "tonsils" refers to the palatine tonsils that can be
seen in the back of the throat.
Vaccine - an immunity booster to a certain disease. Vaccines can be prophylactic (e.g. to
prevent or ameliorate the effects of a future infection by any natural or "wild" pathogen), or
therapeutic (e.g. vaccines against cancer are also being investigated).
Inner liquid environment of the body
Blood plasma- the liquid part of the blood.
Lymph- Blood plasma that escapes from the blood vessels is absorbed into the surrounding
tissue. This tissue fluid collects in tubes throughout the body and is known as lymph.
Tissue liquid- it’s contained in the spaces between the cells. Participates in the exchange
of materials between the blood and cells.
Diseases and hygiene of the cardiovascular system
Anemia or anæmia/anaemia from the Greek meaning "without blood"- a deficiency of red
blood cells and/or hemoglobin. This results in a reduced ability of blood to transfer oxygen to
the tissues, causing tissue hypoxia.
Angina pectoris- chest pain due to ischemia (a lack of blood and hence oxygen supply) of the
heart muscle.
Hypertonia is a condition marked by an abnormal increase in the tightness of muscle tone
and a reduced ability of a muscle to stretch (i.e. an increased stiffness). It is generally
accompanied by (increased) spasticity of the particular muscles.
Leukaemia- increasing or decreasing of the leucocytes in the blood.
Stress- psychic tension.
