What is the relationship between the heart and the lungs?
both make sure the body has oxygen rich blood
What is the pathway of blood in and out of the heart in pulmonary and systemic circulation?
Systematic- Left Atrium- Left Ventricle- Aorta- arteries- Arterioles- Capillaries- Venule's -Veins-Right Atrium-Right Ventricle
How do the structure of arteries, veins and capillaries relate to their function in the body?
Arteries- expand and contract to handle high pressure. Veins- prevent backflow. Capillaries- allow movement of material
What unique features of veins help move blood back to the heart?
The one layer of smooth muscle
What are varicose veins

What are the major arteries and veins in the body and which regions do they serve?
Aorta , Coronary Artery, Pulmonary Arteries. Superior vena Cava, Inferior Vena Cava, Pulmonary Veins
What is cardiac output?
Volume of blood the heart pumps per min (ml/min)
How does cardiac output help assess overall heart health?
Needed to move oxygen and nutrients to all the body's tissue
How does an increased or decreased cardiac output impact the body?
Lower- tissues suffer or blood pressure is unheathly. Increases- can strengthen the heart
What is blood pressure?
Measure of how fast molecules in blood are hitting artery walls
How can the measurement of blood pressure in the legs be used to assess circulation?
Measure how well blood is circulating to the limbs
What is peripheral artery disease?
Partial or total blockage of an artery
Why can smoking lead to peripheral artery disease?
damages the artery which allows for plague to build up on the artery
Know the feedback loop
Diagram of the heart
calculated using systolic pressure and measures how well your blood is flowing
muscle cramping that happens after or during movement
Cardaic output equation
stroke volume (ml/beat) x heart rate (beats/min) + 1000 (to get L)
