Blood vessels lab

Describe flow of blood through vessels

Heart to arteries to arterioles to capillaries to venules to veins and back to heart

What are the 3 types of arteries

Elastic, muscular, and arterioles

Describe elastic arteries

Are close to the heart. They stretch and recoil to help propel blood through vessels

Describe muscular arteries

Medium to small sized arteries

Describe arterioles

They distribute blood to the capillary beds

Describe capillariess

Where exchange of gases and nutrients happens

Describe veins

Veins have thinner walls than arteries. Many veins have valves to ensure one-way flow of blood

Label common carotid, external carotid, internal carotid, vertebral, and basilar

Common carotid is second arrow up on left. Is thick and going through neck. External carotid branches off of common carotid to be more anterior. Internal carotid is the branch more posterior. Vertebral artery goes up spinal cord and basilar artery goes up from axis up towards where ear is

Describe basilar artery

Two vertebral arteries fuse to make basilar artery

Label subclavian artery, vertebral artery, axillary artery, brachial artery, radial artery, and ulnar artery

Subclavian artery is below collarbone, vertebral arteries are on sides of neck, axillary artery is bottom of arm through armpit, brachial artery is actually down arm to elbow and then radial goes down thumb side and ulnar goes down pinky side

Label these arteries branching off abdominal aorta: celiac trunk, common hepatic, splenic, superior mesenteric, inferior mesenteric, renal, gonadal, common iliac, external iliac, internal iliac

Celiac trunk is the big artery below liver and stomach tops, common hepatic goes off celiac trunk to right, splenic came off celiac trunk in middle, superior mesenteric is the larger artery that goes off bottom of celiac trunk to the right, inferior mesenteric artery is what branches off left of bottom of celiac trunk, renal arteries branch out to kidneys, gonadal is branch off celiac trunk above inferior mesenteric artery, common iliac is what starts going down right leg, external iliac is more towards outside of leg while inferior is more medial

Where is femoral artery

Large artery that goes down middle of leg. Is very bottom left arrow.

Label popliteal artery, posterior tibial artery, anterior tibial artery, and dorsalis pedis.

Popliteal artery is top left arrow on lateral side of leg above knee. Posterior tibial is second arrow down on the right starting at the knee. The anterior tibial artery is going down more inner calf. Dorsalis pedis is at your ankle.

Label external jugular, internal jugular, brachiocephalic vein, superior vena cava, subclavian vein, axillary vein, brachial vein, radial vein, and ulnar vein

External jugular is bottom of neck more lateral and internal jugular is wider and more anterior at bottom of neck. Brachiocephalic vein is thick coming up from superior vena cava and up to the left. Superior vena cava is coming out of heart and up. Subclavian vein is up and to the right out to the shoulders. Everything else is just with its anatomical part

Label popliteal vein, femoral vein, external iliac vein, internal iliac vein, common iliac vein

Popliteal vein is in knee, femoral vein is in femur, external iliac vein is branching lateral in hip out towards legs. Internal iliac vein branches medial in hips. Common iliac vein branches off of inferior vena cava into right and left and is right before it splits into external and internal iliac veins

Label these veins of hepatic portal system: hepatic portal vein, superior mesenteric vein, and splenic vein

Hepatic goes through liver, superior mesenteric artery is between stomach and pancreas, and splenic vein is from the liver to the spleen

What does the hepatic portal vein do

The hepatic portal vein gets blood from the digestive organs that is nutrient-rich and takes that blood to the liver for storage or conversion of nutrients

Label umbilical vein, ductus venosus, umbilical arteries, foramen ovale, and ductus arteriosus

Umbilical vein leaves liver out to placenta, ductus venosus is umbilical vein just as it is going through the liver, umbilical arteries are at the very bottom right arrow, foramen ovale is in heart and ductus arteriosus is on more left side of heart than foramen ovale

What does umbilical vein do?

Carries oxygenated and nutrient-rich blood

What is the ductus venosus

Is a shunt to bypass the liver

What are the umbilical arteries

Carry blood back to placenta from the fetus

What is the ductus arteriosus

Connector of pulmonary trunk and aorta to bypass lungs

Look at ductus arteriosus and foramen ovale

OooOOoo

What are arteries and veins in head and neck

You have your carotid arteries and jugular veins

What branches off of the common carotid artery?

External carotid and internal carotid are the main ones

Describe branches of aorta.

First celiac trunk, into splenic artery and common hepatic artery, superior mesenteric artery, left and right renal arteries, inferior mesenteric artery, which is where abdominal aorta branches into common iliac arteries and then the internal iliac and external iliac. Gonadal arteries are in the abdominopelvic region to supply the gonads
