CARDIOVASCULAR SYSTEM Objectives
Identify the parts of the heart and the pathway of the blood through cardiopulmonary circulation.
Describe how peripheral resistance, (e.g. blood vessel diameter, viscosity and vessel length) affects blood flow through resistance.
Identify and explain the effect of blood borne vasoconstriction factors like Epinephrine, Angiotensin II Vasopressin on blood vessels.
Explain how diseases like arteriosclerosis reduce the vessel elasticity and the effect of vessel elasticity on blood pressure.
Analyze the effects of decreasing or increasing blood volume and its correlation on blood pressure

7. Day 1: Cardiovascular System How does it do it
The heart is a muscular organ that is responsible for pumping blood to all parts of the body
Click on this image to activate an interactive look at the heart, it’s function and blood flow pathways.

8. Day 1: Cardiovascular System: 2-Way Circulation
There are two Circulatory Pathways:
systemic circulation,
pulmonary circulation.
First click on the video and have students take guided notes. Next, they can put their knowledge to the test by completing the attached worksheet on the anatomy of the heart. The two activities should take no longer than 30 minutes.
Briefly compare and contrast the two circulatory circuits

Blood Vessels, Pulmonary and Systemic Circulation

9. Day 1: Cardiovascular System: Right Heart Chambers: Pulmonary Circuit
Pulmonary circulation involve the flow of blood poor in Oxygen from the right chambers into the lungs.
Right Atrium
Receives O2-poor blood from body via IVC, SVC
First click on the video and have students take guided notes. Next, they can put their knowledge to the test by completing the attached worksheet on the anatomy of the heart. The two activities should take no longer than 30 minutes.
Right Ventricle
Receives O2-poor blood from right atrium through tricuspid valve
Pumps blood to lungs

10. Day 1: Cardiovascular System: Left Heart Chambers: Systemic Circuit
Systemic Circulation involve the flow of blood rich in Oxygen from the left heart chambers to other parts of the body
Left Atrium
Receives O2-rich blood from Pulmonary Veins
First click on the video and have students take guided notes. Next, they can put their knowledge to the test by completing the attached worksheet on the anatomy of the heart. The two activities should take no longer than 30 minutes.
Left Ventricle
Receives blood from Left Atrium via bicuspid valve
Pumps blood into aorta via Aortic Semilunar Valve to body

13. Day 1: Cardiovascular System The vessels
The Vascular System is made up of many connective tunnels through which blood flows
Capillary is the bridge between veins and arteries…they are so small that materials in blood cell diffuse through them
The vascular system is made up of three main types of blood vessels:
1. ARTERIES
3. VEINS
HEART
CIRUCLATION OF BLOOD THRU THE VESSLES
ARTERIOLES
(smaller Arteries)
VENULES
(smaller Veins)
Exchange of materials through diffusion
CAPILIARIES
2. CAPILIARIES

14. Day 1: Cardiovascular System Arteries
Arteries are blood vessels that carry blood, rich in oxygen, from the heart to other parts of the body.
The large arteries have thick walls of elastic-like tissue that enables them to withstand the blood pressure created by the heart’s beating.
