Blood vessels Lab

These three combine to form the Hepatic portal vein.

*splenic vein *Inferior mesenteric vein *superior mesenteric vein

Internal Carotid arteries

A These arteries are the lateral branches of common carotid arteries. They carry blood to the brain.

Name tissues of C, D, and E?

A: Arterioles B: Vein C: tunica externa D: tunica media E: tunica intima F: artery

Carotid artery, external jugular vein, left jugular vein

A: External carotid artery: supplies blood to the face & neck B: left external jugular vein: drains the head, face & part of the pectoral region. drains to subclavian vein from cranium, face. C: left internal jugular vein: collects blood from the brain & superficial parts of the face & neck. drains to brachiocephalic vein

Blood vessels

A: Subclavian vein: drains the upper extremity, arising from the axillary veins. B: Brachiocephalic vein: drains from L & R internal thoracic vein C: Left common carotid artery: supply head & neck.

Can you name which body parts/organs these vessels supply or drain?

A: hepatic artery, B: splenic artery, C: abdominal aorta, D: inferior vena cava, E: right renal artery, F: right renal vein.

Can you identify which vessels precede or follow each of these vessels? What does each supply?

A: inferior vena cava, B: abdominal aorta, C: left common iliac artery, D: right common iliac vein, E: left femoral artery.

Where do they go? What do they do? Where did they come from?

A: right brachial artery B: right ulnar artery C: right radial artery

Can you name the tissue types for each of these layers?

Adventitia (tunica externa): Dense Irregular connective tissue Tunica Media: smooth muscle tissue Endothelium (tunica intima) inner layer: Simple squamous epithelium

Note the major differences between arteries and veins.

Arteries have a proportionally thicker tunica media than do veins. Veins often flatten during slide preparation due to the thinner walls.

Circle of Willis

B anastomosis (redundant pathways to/from a structure)

Which blood vessels emerge from the aortic arch? Where was the blood just before it entered the arch? left ventricle

Brachiocephalic artery, left common carotid artery, left subclavian artery. supply blood to the head, neck, thorax & upper limbs. Arch-shaped region of the aorta just after emergence from the heart.

1st blood vessel: emerge from the aortic arch. What two arteries does this artery branch into? What is the meaning of the word "brachiocephalic."

Brachiocephalic artery: Right common artery & Right subclavian artery Supply right arm & head Definition: Of or involving the arm & head.

Basilar artery

C An artery, formed by the fusion of the vertebral arteries, that supplies blood to the brainstem and to the posterior cerebral arteries.

Vertebral arteries

D Arteries that ascend the vertebrae, enter the base of the skull, and join together to form the basilar artery.

Blood Vessels 1

D: Left subclavian artery: supplies blood to left arm E: left axillary artery: supplies blood to upper limbs axilla F: left brachial artery: supply the biceps brachii muscle, triceps brachii muscle, and coracobrachialis muscle.

Blood Vessels 2

G: superior vena cava: drains to right atrium. H: aortic arch: supply blood to head, neck, thorax & upper limbs. I: pulmonary trunk: supplies blood to the middle & inferior lobes of the lungs.

2nd artery to branch off of the aortic arch. Supplies blood to the left side of the head.

Left common carotid artery

1st to emerge from the abdominal aorta. Which three major blood vessels does the celiac trunk branch into?

Left gastric, Splenic, Common hepatic Supplies blood to the stomach, liver, spleen, duodenum, and pancreas.

One of two branches of the brachiocephalic trunk. What does the right subclavian artery supply blood to?

Right arm & shoulder. branching to head and thorax.

One of two branches of the brachiocephalic trunk. What is the other branch of the brachiocephalic trunk?

Right subclavian artery supplies to right arm. **right common carotid artery supplies the right side head & neck

2nd to emerge from the abdominal aorta. Why is it called the anterior mesenteric artery in rats, but the superior mesenteric artery in humans? Why is the word "mesenteric" in its name?

Supplies large portions of the small and large intestines

Capillaries

any of the fine branching blood vessels that form a network between the arterioles and venules. They only have the tunica intima.

Inferior mesenteric vein

drains parts of the large intestine

superior mesenteric vein

drains the small intestine and parts Ig. Int.

Splenic Vein

drains the spleen and part of the stomach

Last arteries (L and R) to branch off from the abdominal aorta. Which artery on your list do the iliac arteries become? What does the word "iliac" refer to?

femoral artery Iliac: to or near the ilium bone The abdominal aorta ceases to exist with the formation of these arteries. They supply the hips and legs.

3rd artery to branch off of the aortic arch.

left subclavian artery: supplies the left shoulder and arm. It goes on to become the axillary artery, then the brachial artery.

Usually the 3rd major branch off of the abdominal aorta, the L and R renal arteries supply the kidneys. What does "renal" mean?

of or relating to, involving or located in the kidney region

Hepatic portal system

system of veins that transport nutrient rich blood from the digestive system to the liver
