Flashcards in Lecture 5 Deck (42):
before birth, blood leaves the right atrium to bypass the lung through:
Ductus arteriosus and
A connection between the 6th aortic arch:
A hole between the right and left atria, allowing blood to pass from the right side to the left side and not ever get pumped into the lungs:
Allows blood to skip past the lungs and join up with partially oxygenated blood that is being pumped out of the left ventricle:
Where does the spent blood from the fetus go?
The distal end of the internal iliac artery is an old connection of the _________ which goes towards the placenta
Oxygenated blood returning to the fetus returns via the:
Where does more oxygen-rich blood pass through on the fetus?
Foramen ovale over to the left side
A pathway from the placenta to the upper region of the IVC bypasses the liver through the:
The _____ umbilical vein eventually degenerates
Closes at the moment of birth:
Foramen ovale and ductus arteriosus
What closes the foramen ovale?
interatrial flap valve
The umbilical vein becomes the:
round ligament of the liver
Ductus arteriosus turns into what in the adult?
Ductus venosus turns in what in the adult?
The thinnest, smoothest part of the interatrial wall:
When the foramen ovale fuses into the interatiral wall, it then becomes:
4 functions of the integumentary system:
Removal of cellular debris and invading micro-organisms:
2 types of phagocytes:
Natural killer cells adhere to abnormal cells and tear them open with an enzyme called:
Responsible for "cell-mediated immunity"
-a specific defense against invading foreign cells:
Responsible for "humoral immunity"
-defense by means of antibodies:
Specific antibodies and natural antibodies
Proteins that have the shape of a letter "Y":
4 types of T-lymhpocytes:
Matures in bone marrow
Matures in thymus gland
Made up of 5 antibodies:
Made up of 2 antibodies :
Main antibody in blood:
A new class of antibodies that begins production before birth :
Part of a waste removal system that helps clean up dead, dying, and damaged cells of "self"
