Use the figures, tables, and text from chapters13-15 & 26 in Tortorato correctly complete this bonusassignment. Be as complete as possible in finding anylocations and functions of structures, since this material will surface on Exam 4.

Heart Blood Flow Learning Exercise

Blood flows through the heart in a specific sequence (1-way flow). Venous blood first enters the heart via the right atrium. In the exercise below, number the structures according to when blood passes through them. Some of the structures have already been numbered for you. Use Fig. 14.7 (pg. 434) in your text to assist you.

_____ Right Ventricle

_____ Left Ventricle

_____ Pulmonary trunk and pulmonary arteries

_____ exchange of gas occurs in the lungs

_____ aorta and arteries throughout

_____ pulmonary veins

__1__ right atrium

_____ left atrium

__9__ veins throughout body, back to right atrium

NOW, make your own flowchart, and rewrite this sequence out in order - this will help you remember the blood pathway!

Are there any structures within the heart or vessels that prevent the backflow of blood? If so, what are they and where are they located? (Hint: text pg. 432-434 and Fig. 14.6)

BIOLOGY 2423: BLOOD VESSELS Memory Matrix

Use text pg. 454-458& Fig. 15.1to assist you.

Blood Vessel / Characteristics / Which tunic is the largest? / Does gas/nutrient exchange occur here? / This vessel takes blood to ____
Elastic Artery
Muscular Artery
Arteriole
Capillary
Venule
Vein

BIOLGOY 2423: Blood Pathway Learning Exercise

Fill in the boxes with the blood vessels of the system circuit that take blood to the tissues, and back to the heart again. Use text pg. 454-458 and Fig. 14.7 (pg. 434-435) to assist you.

Heart

sends blood to

(and main elastic branches)

which send blood to

(these are muscular)

which send blood to

(these are the smallest arteries)

which send blood to

(gas/nutrient exchange occurs here!!)

which send blood to

(these are the smallest veins)

which send blood to

(these join the above & become the venae cavae)

Blood is drained back into heart (and the cycle repeats)

HEPATIC PORTAL SYSTEM Learning Exercise

Blood flows through the hepatic portal system in a specific sequence. In the exercise below, number the structures according to when blood passes through them. Some of the structures have already been numbered for you. Use text pg. 500-501 and Fig. 15.15 to assist you.

_____ Inferior Vena Cava

_____ Superior Mesenteric, Inferior mesenteric,and splenic veins

__1__ tiny veins in walls of GI tract

_____ Hepatic portal vein

_____ Liver

KIDNEYBLOODFLOW Learning Exercise

Blood flows through the arteries and veins of the kidney in a particular sequence. In the exercise below, number the structures according to when blood passes through them. Some structures have already been numbered for you. Use text pg. 813-814, along with Fig. 26.4 to assist you.

_____ arcuate arteries

_____ afferent arteriole

_____ interlobular artery

_13__ renal vein (drains into inferior vena cava)

_____ interlobar artery

_____ glomerulus

_____ interlobar vein

__1__ renal artery (receives blood from aorta)

_____ efferent arteriole

_____ segmental artery

_____ peritubular capillaries or vasa recta

_____ interlobular vein

_____ arcuate vein

NOW, make your own flowchart, and rewrite this sequence out in order - this will help you remember the kidney blood flow pathway! Are there any structures omitted from the above sequence? If so, add them to your flow chart in the correct order.
