What is chorda-tendinae and what is their function |
Fibrous cords that connect free edge of AV valves to papillary muscles, prevent valves from everting into the artium and prevent leakage of blood into atria at time of ventricular contraction |
|

Name the veins which bring oxygenated blood to left atrium |
pulmonary veins |
|
|
Major veins that bring unoxygenated blood to the right atrium |
cranial and caudal vena cava |
|
|
What is the main function of semilunar valves? |
prevent backflow of blood from aorta and pulmonary arteries into the ventricles |
|
|
Membrane that encloses the heart |
pericardium |
|
|
Where are papillary muscle located and what is their function? |
conical projections in the ventricles, each valve receives chorda-tendinea from at least 2 papillary muscles |
|
|
Name the veins which carry oxygenated blood |
pulmonary |
|

Other name for bicuspid valve which guards left AV opening |
mitral |
|

yes, it is part of visceral pericardium |
|
|
Name the 3 layers of the heart |
epicardium , myocardium, endocarduim |
|
|
What is the diff between AV and semilunar valves in location? |
AV- located at junction of artia and ventricles Semilunar- guard opening of aorta and pulmonary artery in ventricles |
|
|
Name the arteries which supply blood to the small and large intestines |
anterior and posterior mesenteric |
|
|
What is ductus arteriosus |
duct that connects the pulmonary artery to the aorta during fetal life |
|
|

opening in inter-atrial septum between R and L atrium during fetal life |
|
|
Name 2 short cuts from R to L side of heart during fetal life. |
foramen ovale and ductus arteriosus |
|
|
Liver receives blood from how many blood vessels |
hepatic artery (oxygenated blood) and portal vein (nutrients from stomach and intestines) |
|
|
What is the main function of hepatic portal cirulation |
detoxification, modification and storage on nutrients |
|
|
What is portal circulation |
special arrangement of blood vessels where a vein breaks up into capillaries and then recombines again to form another vein |
|
|
Which side of the heart contains pure oxygenated blood |
left |
|
|
Name the artery that supplies blood to the kidneys |
renal |
|
|
Name the artery that carries unoxygenated blood |
pulmonary |
|
|
Which major branch of the abdominal aorta provide blood to the stomach, liver, and spleen |
celiac |
|
|
What is systemic circulation |
movement of blood from heart to body tissues and back to the heart |
|
|
What is pulmonary circulation |
movement of blood from the heart to the lungs and back to the heart |
|
|
Name the part of the circulatory system which allows the exchange of gases and waste products at tissue level |
capillary bed |
|
|
Why are arterioles highly muscular structures |
Arterioles are surrounded by smooth muscle and control the flow of blood into capillaries |
|
|
What is ductus venosus |
duct that connects umbilical vein directly to vena cava, bypassing the liver during fetal life |
|
|
Name the arteries that supplies blood to the ovaries |
ovarian arteries |
