Cardiovascular Lab Flashcards
Umbilical Arteries/ Veins
Vessels that bring oxygenated blood from the placenta to the fetus and take deoxygenated blood from the fetus to the placenta respectively.
Interventricular Septum
structure in the heart that separates the ventricles.
Pulmonary Veins
vessels that carry oxygenated blood from the lungs to the left atrium
In the pulmonary circuit, what carries deoxygenated blood and oxygenated blood?
Oxygenated blood- veins
Deoxygenated blood- arteries
In the systemic circuit, what carries deoxygenated blood and oxygenated blood?
Oxygenated blood- arteries
Deoxygenated blood- veins
Right and Left Subclavian Arteries
carry oxygenated blood; right subclavian branches off brachiocephalic trunk; left subclavian artery branches off the aorta
Femoral Veins/Arteries
Carries deoxygenated/oxygenated blood from lower limbs to external iliac veins
Umbilical Cord
flexible tube of blood vessels that connects the fetus to the placenta
Apex
the bottom of your heart that is point- shaped
Bicuspid Valve
AKA mitral valve; blood flows from left atrium to left ventricle through this valve; valve ensures blood flow in one direction
Which chamber of the heart is the largest? Why?
Left ventricle; it pumps high pressured blood to the aorta which is then taken to the rest of the body
Papillary Muscles
cardiac muscle
Coronary Veins
vessels that take the deoxygenated blood away from the heart muscle; can see them on the outside of the heart
Left and Right External Jugular Veins
carries deoxygenated blood from face and brain; carries this blood to the subclavian veins
Aorta
the largest artery; carries high pressured oxygenated blood from the left ventricle to the systemic circuit
Celiac Artery
comes off the descending aorta to provide oxygenated blood to digestive tract
External Iliac Veins
carries deoxygenated blood from femoral veins to the inferior vena cava
External Iliac Arteries
carries oxygenated blood to the femoral arteries
Where do the left and right external iliac arteries split from?
they are the splitting of the aorta
Tricuspid Valve
blood flows from right atrium to right ventricle through this valve; valve ensures blood flows in one direction
Heart
organ that pumps blood through the rest of the circulatory system; contains four chambers- left and right atrium and left and right ventricle
Chordae Tendineae
tendons that connect the heart muscle to the tricuspid and bicuspid valves
Pulmonary Arteries
vessels that carry deoxygenated blood from the right ventricle to the lungs
Brachiocephalic Trunk (artery)
carries oxygenated blood from the aorta; first branch off aorta; divides into right subclavian artery; right common carotid artery (and in pigs the left common carotid artery)
Renal Veins
carries deoxygenated blood from kidneys to inferior vena cava
Pericardial Sac
contains the heart and pericardial fluid which cushions and lubricates the outer heart
Spleen
stores blood; filters blood; produces some white blood cells
Pulmonary Semilunar Valve
found between the right ventricle and the pulmonary trunk; this valve stops blood flowing from pulmonary trunk into right ventricle
Coronary Arteries
vessels that bring oxygenated blood to the heart muscle
Right and Left Auricle
extensions of the right and left atria on the outside of the heart
Left and Right Subclavian veins
carries deoxygenated blood from other smaller veins; carries this blood to brachiocephalic vein
Right and Left Common Carotid Arteries
carry oxygenated blood; in pigs both branch off the brachiocephalic artery; in humans the left common carotid artery branches off the aorta
Aortic Semilunar Valve
found between the left ventricle and the aorta; this valve stops blood flowing from the aorta into the left ventricle
Hepatic Portal Vein
carries blood from digestive tract, pancreas, spleen, and gallbladder to liver
Left and Right Brachiocephalic Veins
carry blood from the internal jugular veins and subclavian veins; carry deoxygenated blood to the superior vena cava
Ductus Arteriosus
shunts blood from right ventricle to aorta thus by passing lungs as fetus will exchange gases in placenta
Renal Artery
branches off descending aorta to provide oxygenated blood to kidneys
Superior Vena Cava
large vein that beings deoxygenated blood from the anterior (or inferior in human) part of the body to the right atrium
Inferior Vena Cava
large vein that bring deoxygenated blood from the posterior (or inferior in human) part of the body to the right atrium
Blood Flow
right atrium ➡️ tricuspid valve ➡️ right ventricle ➡️ pulmonary valve ➡️ pulmonary arterioles ➡️ capillaries of the lungs ➡️ pulmonary venules ➡️ pulmonary veins ➡️ left atrium ➡️ bicuspid valve ➡️ left ventricle ➡️ aortic valve ➡️ aorta ➡️ systemic arteries ➡️ systemic arterioles ➡️ systemic capillaries ➡️ systemic venules ➡️ systemic veins ➡️ inferior and superior vena cava ➡️ right atrium
