Q

External Iliac Veins

A

carries deoxygenated blood from femoral veins to the inferior vena cava

18
Q

External Iliac Arteries

A

carries oxygenated blood to the femoral arteries

19
Q

Where do the left and right external iliac arteries split from?

A

they are the splitting of the aorta

20
Q

Tricuspid Valve

A

blood flows from right atrium to right ventricle through this valve; valve ensures blood flows in one direction

21
Q

Heart

A

organ that pumps blood through the rest of the circulatory system; contains four chambers- left and right atrium and left and right ventricle

22
Q

Chordae Tendineae

A

tendons that connect the heart muscle to the tricuspid and bicuspid valves

23
Q

Pulmonary Arteries

A

vessels that carry deoxygenated blood from the right ventricle to the lungs

24
Q

Brachiocephalic Trunk (artery)

A

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)

25
Q

Renal Veins

A

carries deoxygenated blood from kidneys to inferior vena cava

26
Q

Pericardial Sac

A

contains the heart and pericardial fluid which cushions and lubricates the outer heart

27
Q

Spleen

A

stores blood; filters blood; produces some white blood cells

28
Q

Pulmonary Semilunar Valve

A

found between the right ventricle and the pulmonary trunk; this valve stops blood flowing from pulmonary trunk into right ventricle

29
Q

Coronary Arteries

A

vessels that bring oxygenated blood to the heart muscle

30
Q

Right and Left Auricle

A

extensions of the right and left atria on the outside of the heart

31
Q

Left and Right Subclavian veins

A

carries deoxygenated blood from other smaller veins; carries this blood to brachiocephalic vein

32
Q

Right and Left Common Carotid Arteries

A

carry oxygenated blood; in pigs both branch off the brachiocephalic artery; in humans the left common carotid artery branches off the aorta

33
Q

Aortic Semilunar Valve

A

found between the left ventricle and the aorta; this valve stops blood flowing from the aorta into the left ventricle

34
Q

Hepatic Portal Vein

A

carries blood from digestive tract, pancreas, spleen, and gallbladder to liver

35
Q

Left and Right Brachiocephalic Veins

A

carry blood from the internal jugular veins and subclavian veins; carry deoxygenated blood to the superior vena cava

36
Q

Ductus Arteriosus

A

shunts blood from right ventricle to aorta thus by passing lungs as fetus will exchange gases in placenta

37
Q

Renal Artery

A

branches off descending aorta to provide oxygenated blood to kidneys

38
Q

Superior Vena Cava

A

large vein that beings deoxygenated blood from the anterior (or inferior in human) part of the body to the right atrium

39
Q

Inferior Vena Cava

A

large vein that bring deoxygenated blood from the posterior (or inferior in human) part of the body to the right atrium

40
Q

Blood Flow

A

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
