What types of muscle help move blood around the body?
The heart is the primary muscle that helps move blood & is made of cardiac muscle tissue. It is responsible for the circulation of blood & all the materials in it.
The heart and lungs work together to get oxygen to the tissues. The heart pumps the blood, and the lungs put oxygen into it. This oxygen-rich blood then circulates throughout the body to nourish the cells; oxygen-depleted blood gets collected from the tissues to be oxygenated in the lungs
The right side of the heart collects deoxygenated blood into its atrium & then passes it into the ventricle. The right ventricle then pushes the blood to the lungs, where the CO2 is dropped off and O2 is picked up.
Three layers of thick, fairly rigid walls to allow them to expand/contract & to handle high pressure (blood has greatest pressure as it's leaving the heart)— one layer is smooth muscle

What unique features of veins help move blood back to the heart?
Valves
Venule
Cappillary
Arteriole
What are varicose veins?
are big, twisty veins near the skin's surface that are caused by weakened valves.
Any of the minute veins connecting the capillaries with the larger systemic veins
A bodily structure that closes temporarily a passage or orifice or permits movement of fluid in one direction only
A regularly recurrent wave of distension in arteries that results from the progress through an artery
What are the major Superior Vena Cava vein in the body and which regions do they serve?
carries deoxygenated blood from the upper body (arms and head) back to the heart
The volume of blood the heart pumps perminute (mL/min) out of the left side
Normal cardiac output is needed to move oxygen and nutrients to all the body's tissues.
If a person's cardiac output is lower than normal, the tissues can suffer or blood pressure can become unhealthy. An increased cardiac output from exercise can help strengthen the heart.
What is cardiac output?
carries deoxygenated blood from the upper body (arms and head) back to the heart
The volume of blood the heart pumps perminute (mL/min) out of the left side
Normal cardiac output is needed to move oxygen and nutrients to all the body's tissues.
If a person's cardiac output is lower than normal, the tissues can suffer or blood pressure can become unhealthy. An increased cardiac output from exercise can help strengthen the heart.
How does cardiac output help assess overall heart health?
carries deoxygenated blood from the upper body (arms and head) back to the heart
The volume of blood the heart pumps perminute (mL/min) out of the left side
Normal cardiac output is needed to move oxygen and nutrients to all the body's tissues.
If a person's cardiac output is lower than normal, the tissues can suffer or blood pressure can become unhealthy. An increased cardiac output from exercise can help strengthen the heart.
How does an increased or decreased cardiac output impact the body?
carries deoxygenated blood from the upper body (arms and head) back to the heart

How do the structure of veins relate to their function in the body?
Three layers of elastic/collapsible walls with valves to prevent the back flow of blood as it moves toward the heart— one layer is smooth muscle
Thin walled (one cell layer thick) & microscopic in size to allow exchange of materials, often have pores to allow movement of materials
blood is pushed out of the heart by the left ventricle & then it branches into all other arteries in the body
this is the artery that runs across the ventral side of the heart, nourishing the cardiac tissue itself
