Transcript of Blood Vessels

Big Idea 1: Blood vessels Big Idea 2: Major Arteries Big Idea 3: Major Veins Blood Vessels April 26 Cardiac Cycle Review Sponge Commercial Break!!! Commercial Break!!! Commercial Break!!! SWBAT describe the structure and function of the three types of blood vessels Cardiac Cycle Sponge (complete in your composition notebook)
1. Write the daily objective
2. What is the name for heart relaxation?
3. What is the name for a heart contraction?
4. What is the phase in the cardiac cycle when the ventricles contract,
forcing blood up to the lungs/body?
5. Which node is the "pacemaker" node of the heart? Table of Contents 4/26 Cardiac cycle review sponge
Blood vessels notes Homework Week 16 homework on Quia is due Sunday 4/28 by 11:59 pm


Tutorial is Monday of next weeks
There is a speaker on Thursday of next week (5/2) Transport blood to the tissues and back
Carry blood away from the heart
Arteries
Arterioles
Exchanges between tissues and blood
Capillary beds
Return blood toward the heart
Venules
Veins Blood Vessels: The Vascular System Three layers (tunics)
1. Tunic intima
Endothelium
2. Tunic media
Smooth muscle
Controlled by sympathetic nervous system
3. Tunic externa
Mostly fibrous connective tissue Blood Vessels: Microscopic Anatomy Differences Between Blood Vessels Walls of arteries are the thickest
Lumens of veins are larger
Larger veins have valves to prevent backflow
Skeletal muscle “milks” blood in veins toward the heart
Walls of capillaries are only one cell layer thick to allow for exchanges between blood and tissue Most arterial blood is pumped by the heart
Veins use the milking action of muscles to help move blood Movement of Blood Through Vessels Capillary beds consist of two types of vessels
1. Vascular shunt—vessel directly connecting an arteriole to a venule
2. True capillaries—exchange vessels
Oxygen and nutrients cross to cells
Carbon dioxide and metabolic waste products cross into blood Capillary Beds Quick Check!!!
1. Which type of blood vessel is the most muscular?
2. Which type of blood vessels moves blood from the
milking action of skeletal muscles?
3. Which blood vessels allow for the exchange of oxygen and nutrients into cells? Aorta
Largest artery in the body
Leaves from the left ventricle of the heart
Regions
Ascending aorta—leaves the left ventricle
Aortic arch—arches to the left
Thoracic aorta—travels downward through the thorax
Abdominal aorta—passes through the diaphragm into the abdominopelvic cavity Major Arteries of System Circulation Figure 11.12 Major Arteries of Systemic Circulation Quick Check!!!
1. What is one of the branches of the aorta?
2. What is the name of the artery that is used to take your blood pressue? Superior and inferior vena cava enter the right atrium of the heart
Superior vena cava drains the head and arms
Inferior vena cava drains the lower body Major Veins of Systemic Circulation Bill Nye The Science Guy
