cardiovascular, immune, lymphatic, blood Flashcards
pathway of the blood through the body
a closed loop circulation between the heart and body tissue
pathway of blood through heart
Blood comes into the right atrium from the body,
moves into the right ventricle and is pushed into the pulmonary arteries in the lungs.
After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.
pathway of blood through lungs
pulmonary circulation; a closed loop circulation b/w the heart and lungs for gas exchange
Heart
pumps blood throughout the circulation system
where is the atria
top of heart
where is the ventricles
bottom of heart
hematopoiesis
Stem cells in the bone marrow develop into different types of blood cells (hematopoiesis) which are rbcs, wbcs, and thrombocytes (platelets).
arteries
Arteries are blood vessels that carry blood AWAY from the heart
arterioles
tiny arteries that carry blood AWAY from heart
venules
tiny veins that carry blood TOWARD the heart
venae cavae
Venae cavae is the largest vein the body. (inferior and superior)
aorta
largest artery in body; in left ventricle; in neck
veins
carry blood TOWARD heart; carry co2 rich blood because they carry blood from LUNGS to HEART
myocardium
the muscular tissue of the heart.
pericardium
2 layer sac surrounding the heart; contains the epicardium and the parietal pericardium
epicardium
outer lining covering the heart
endocardium
inner lining of the heart
myocardium
the muscular tissue of the heart.
plasma
Plasma is the part of your blood that carries platelets, red blood cells and white blood cells around the body. It contains antibodies, known as immunoglobulins, which fight infection. Plasma makes up approximately 55% of your blood.
thrombocytes (platelets)
blood clot formation and tissue repair (located in the buffy coat after centrifuge)
spleen
left of abdominal cavity b/w stomach and diaphragm; largest lympathic organ in the whole body; destroys old RBCs, stores blood. Blood flows through the spleen to be cleansed of microogranisms
thymus gland
on top of aorta, behind the sternum and b/w the lungs; important role in development of body’s immune system from child to adult; shrinks in puberty and after is no longer that important
lymph
colorless tissue fluid full of lymphocytes and monocytes; collected extracurricular fluid that travels away from body tissue to heart in a one way system; is drained into cardiovascular system through ducts in the chest
lymph nodes
small spherical bodies composed of lymphoid tissue; filter lymph to keep bacteria etc from entering the blood
