kahoot 3.4 - 3.10
-
after passing the axilla, the axillary artery becomes the (brachial artery)
-
in the forearm, the brachial artery becomes the (radial and ulnar artery
-
the internal carotids and the basilar artery are inerconnected by an anastomosis called the (circle of willis)
-
-
-
near the level of verebra L4, the aorta branches to form the (common iliac arteries)
after recieving the internal jugular vein, the subclavian vein becomes the (brachiocephalic vein

vicki has a disabled posterior pituitary. what type of cardiovascular affects might you expect (decreased blood volume)
-
in response to hemmorrhage, there is (mobilization)

kahoot 13.3
which of the following factors is the most likely to result in an increase in blood pressure (decrease in blood flow to the kidneys)
which of the following is greater (blood pressure when symopathic stimulation to the heart increases)
-
-
-
the barorecptor reflex causes changes in (blood and stroke volume, and heart rate)
-
which of the following changes will result in increased nutrient delivery to a specific tissue ( relaxation of precapillary spincters)
-
-
when a capillary bed decrases in blood flow due to locally high oxygen levels, it is caused by (autoregulation)

-
compared to veins, arteries (are more elastic)
the vessels that permit exchange of materials between the cells and the blood are termed (capillaries)
kahoot 13.2

-
which of the following conditions would completely stop all NET filtration ( the blood hydrostatic pressure and the blood osomotic pressure are equal in magnitude but opposite in direction)

13.1 arteries, arterioles, capillaries, venules, and veins differ in size, structure, and function
-
arteries
elastic arteries: large, extremely resilient vessels with diameters of up to 2.5 cm
muscular arteries: medium size arteries or distribute arteries, distribute blood to skeletal muscles and internal organs
-
venules
the smallest venules resemble expanded capillaries, and venules with diameters smaller than 50 lack of a tunica media altogether
capillaries
capillaries are the only blood vessels whose walls permit ex-change between the blood and the surrounding interstitial fluid

13.6 in the pulmonary circuit, deoxygenated blood enters the lungs in arteries, and oxygenated blood leaves the lungs in veins
pulmonary arteries
as the pulmonary trunk curves over the superior border of the heart, it gives rise to the left and right pulmonary arteries
alveoli of the lungs
the smallest branches, the pulmonary arterioles, provide blood to capillary networks that surround small air pockets or the alveoli
pulmonary trunk
after traveling through the right atrium and ventricle, blood enters the pulmonary trunk, the start of the pulmonary circuit
pulmonary veins
as oxygenated blood leaves the alveolar capillaries, it enters venules, which it turn unite to form larger vessels leading to the pulmonary veins
13-3 cardiovascular regulation involves auto regulation, neural mechanisms, and endocrine responses
-
neural regulation
baroreceptors
the barorecptors involved in cardiovascular regulation are located in the aortic sinuses, pockets in the walls of the aorta adjacent to the heart
chemorecptors
the chemoreceptors reflexes respond to changes in carbon dioxide, oxygen, or pH in blood and cerebrospinal fluid
-
13.8 modifications of fetal and maternal cardiovascular systems promote exchange of materials, and independence is achieved at birth
placental blood supply
the fetus's blood reaches the placenta through a pair of umbilical arteries, which arise from the internal iliac arteries before entering the umbilical cord
fetal circulation
one of the most interesting aspects of circulatory development reflects the differences between the life of an embryo or fetus and that of an infant
changes at birth
at birth, dramatic changes occur. when an infant takes its first breath, the lungs expand, and so do the pulmonary vessels
-
-
13.7 The systemic circuit carries oxygenated blood from the left ventricle to tissues other than the lung's exchange surfaces, and returns deoxygenated blood to the right atrium
-
-
13.5 the pulmonary and systemic circuits of the cardiovascular system exhibit three general functional patterns
-
13.9 aging affects the blood, heart, and blood vessels
the capabilities of the cardiovascular system gradually decline with age. major changes affect all parts of the cardiovascular system: blood, heart, and vessels
