40B - Lab - Exercise #30 Flashcards
Right and left coronary arteries
Vascularize myocardium
Near origin of ascending aorta
What blood vessels branch off the aortic arch?
Right to left:
- Brachiocephalic trunk
- Left common carotid artery
- Left subclavian artery
What blood vessels branch off the brachiocephalic trunk?
Right common carotid artery and right subclavian artery
What does the descending aorta turn into?
The thoracic aorta then the abdominal aorta
What is the structural and functional relationship of capillaries to other blood vessels?
Capillaries are smaller than arteries and veins and will exchange substances to diffuse into surrounding tissue
What blood vessel do you press down on to take a pulse?
Right and left common carotid artery
What blood vessels branch off the Ascending Aorta?
The right and left coronary arteries
Specific arteries carry deoxygenated blood
In adult: pulmonary arteries
In fetus: umbilical arteries
Specific veins that carry oxygenated blood?
In adults: pulmonary veins
In fetus: umbilical veins
Aortic hiatus
Opening in diaphragm for aorta
Canal opening
Opening in diaphragm for inferior vena cava
Esophageal hiatus
Opening in diaphragm for esophagus
Openings in diaphragm from anterior to posterior
- Canal opening
- Esophageal hiatus
- Aortic hiatus
What does the brachiocephalic trunk vascularize?
Brain and head
What does the right common carotid artery vascularize?
Right side of neck and head
What does the right subclavian artery vascularize?
Right arm
What does the left common carotid artery vascularize?
Left side of neck and head
What does the left subclavian artery vascularize?
Left arm
What blood vessel is used to take a pulse at the wrist?
Right and left radial artery
Which blood vessel is used to take blood pressure?
Right and left brachial artery
Where is blood usually drawn from?
Right and left median cubital vein
What is the longest vein in body?
Great saphenous vein
Placenta
“Vehicle of exchange”
Umbilical Arteries
Carry oxygenated-poor fetal blood to the placenta
Umbilical Vein
Carrys oxygen-rich blood back to fetus
Foramen Ovale
*HELPS BYPASS LUNGS
Opening in atrial septum that allows blood to pass form right to left atrium
Ductus Arteriosus
*HELPS BY PASS LUNGS
Arterial vessel that connects pulmonary trunk with aorta
What does the Foramen Ovale change into?
Closes and becomes fossa ovalis
What does the ductus arteriosus change into?
Closes and becomes the ligamentum arteriosum
Intercalated Disc
Area where muscle cells “snap”
Gap junction
Within intercalated disc and moves ions across from cell to cell
The placenta is a(n) ________ organ
Endocrine
