diffusion
Some animals lack a _______ - answer- circulatory system
A gastrovascular cavity - answer- functions in both digestion and distribution of
substances throughout the body
A circulatory system has - answer- a circulatory fluid, a set of interconnecting
vessels, and a muscular pump called the heart
function of the circulatory system - answer- connects the fluid that surrounds cells
with the different organs of the body
Circulatory systems can be ___ or _____ and vary in the number of ____ in the body
- answer- open, closed, and circuits
In insect, arthropods, and some molluscs, circulatry fluid called ______ bathes the
organs in an _______ - answer- hemolymph, open circulatory system
In a _______ circulatory system ____ is confined to vessels and is distinct from the
interstitial fluid - answer- closed, blood
Humans and other vertebrates have a closed circulatory system called the - answer-
cardiovascular system
Three main types of bloods vessels - answer- arteries, veins, and capillaries
Arteries branch into _____ and carry blood away from the heart to _______ -
answer- aterioles capillaries
Networks of capillaries called ______ are the sites of chemical exchange between
the blood and interstitial fluid - answer- capillary beds
Venules converge into _____ and return blood from the capillaries to the heart -
answer- veins
Arteries and veins are distinguished by the direction of blood flow - answer- arteries
carry blood away from heart; veins to heart
blood enters through an _____ and is pumped out through a _____ - answer- atrium
and ventricle
, Bony fishes, rays, and sharks have a _____ circulation with a _____ chambered
heart - answer- single, two
Single circulation - answer- blood leaving the heart passes through two capillary
beds before returning
Amphibians, reptiles, and mammals have _______ - answer- double circulation
Oxygen poor and oxygen rich blood are pumped separately from the - answer- right
and left sides of the heart
Oxygen rich blood delivers oxygen through the - answer- systemic circuit
frogs and other amphibians have a three chambered heart - answer- two atria and
one ventricle
Turtles snakes and lizards have a three chambered heart - answer- two atria and
one ventricle, partially divided by an incomplete septum
mammals and birds have a four chambered heart - answer- two atria and two
ventricles
the left side of the heart pumps and receives - answer- oxygen rich blood
the right side receives and pumps - answer- oxygen poor blood
Cardiovascular system - answer-
Mammalian heart - answer-
The heart contracts and relaxes in a rhythmic cycle called the - answer- cardiac
cycle
the contraction or pumping phase is called - answer- systole
the relaxation or filling phase is called - answer- diastole
The number of beats per minute is called the - answer- heart rate
the amount of blood pumped in a single contraction is called the - answer- stroke
volume
The volume of blood pumped into the systemic circulation, it depends on both the
heart rate and stroke volume - answer- cardiac output
atrioventricular valves - answer- separate each atrium and ventricleg
semilunar valves - answer- control blood flow to the aorta and pulmonary artery
