Name the 3 layers of a blood vessels in the cardiovascular system. | Tunica Interna, Tunica Media, Tunica Externa |
Tunica Interna is what kind of tissue | Endothelium and Connective Tissue |
Tunica Externa is what kind of tissue | Tough fibrous layer |
Tunica Media is what kind of tissue | Smooth Muslce |
What vessel has a thicker tunica media | Arteries |
What vessel has a one way valve to prevent backflow | Veins |
Why do Arteries have a thicker tunica media | Higher pressure in arteries due to force of the contraction in L ventricle. |
What is the function of the blood moving through the arteries | Pressure expands arterial wall, left ventricle relaxes, arteries shrink back to normal, pushing blood along. |
what vessel has lower pressure. | Veins |
Blood returning to the heart has to work (with or against) gravity | against |
what is the purpose of the valve in the vein. | to prevent backflow since pressure is lower |
name the three main arteries that branch directly from the aortic arch. | Brachiocephalic trunk, left common carotid, left subclavian artery |
The brachiocephalic trunk splits into... | right subclavian and common carotid |
pulmonary truck splits into.. | right and left pulmonary arteries |
the lungs received blood from the right ventricle through what blood vessel | Pulmonary trunk |
common carotid splits into? | Internal and external carotid arteriers |
name vessel that enters skull to reach brain | Internal carotid |
superficial vessels that branches to the face and scalp | External carotid |
The external carotid artery branches to ------ and ------,( artery names not location) | facial artery and superficial temporal artery |
Subclavian arteries are branched from? | Vertebral arteries |
The basilar artery is known as | brain stem artery |
vertebral arteries join to form | Basilar artery |
blood flow through the brain is known as | Circle of Willis |
Axillary artery is a vessels continuation from what artery | subclavian |
what are the small branches that exit axillary artery | brachial artery |
brachial artery splits into how many arteries | 2 |
what artery (ies) forms deep and superficial palmar arches | radial and ulnar arteries |
what is the first major artery on the abdonimal (descending) aorta | Celiac Truck |
the celiac trunk branches into what organs | liver, stomach, spleen |
Celiac trunk branches into how many locations | 3 |
name the artery the celiac trunk branches into. | Hepatic Artery, left gastric artery, splenic artery |
The hepatic artery is located in the | liver |
the splenic artery is located in the | spleen |
which gastric artery is branched from the celiac trunk | left gastric artery |
the left gastric artery is located in the | stomach |
name the abdonimal arteries from the aorta | celiac trunk, left and right renal arteries, right and left gonadal arteries, superior mesenteric artery, inferior mesenteric artery, middle sacral artery |
renal arteries are located in the | kidney |
gonadal arteries are located in | ovaries and testes |
superior mesenteric artery is located | ascending colon & transverse colon |
inferior mesenteric artery is located | descending & sigmoid colon |
middle sacrum artery is located | sacrum |
what artery splits into external and internal iliac arteries | common iliac artery |
external iliac continues down ----- as the ------ | thigh, femoral artery |
artery that travels behind the knee is | popliteal artery |
the popliteal artery is from ------- artery | femoral |
deep femoral stays within thigh and does not travel down leg. (true or false) | True |
you can feel your pulse in what location of lower leg | ankle |
the popliteal artery splits into | anterior tibial, posterior tibial and fibular arteries |
posterior tibial splits into | medial and lateral plantar arteries |
medial and lateral plantar arteries are located in the | foot |
what does the anterior tibila becomes ----- | dorsalis pedis artery |
dorsalis pedis artery is located | on top of the foot |
the vessels that enters the skull to reach the brain is | internal carotid |
name the 6 abdominal arteries from the aorta | celiac trunk, left & right renal arteries, left & right gonadel arteries, superior mesenteric artery, inferior meseteric artery, middle sacrel artery |
process of blood moving through the artery | 1) pressure expands artery walls 2) left ventricle relaxes 3) arteries shrink back to normal pushing blood along |
