|
Pumps blood to service the cells
|
Heart
|
|
|
Where the blood flows
|
Blood Vessels
|
|
|
Blood exchanges substances with it and not directly with cells. blood removes waste products 4rm it. blood brings it the oxygen and nutrients cells need to continue their existence
|
Tissue Fluid
|
|
|
Assistance to the cardiovascular system b/c lymphatic vessels collect excess tissue fluid and return it to the cardiovascular system
|
Lymphatic System
|
|
|
What are 3 types of blood vessels?
|
Arteries, Capillaries, Veins
|
|
|
Comes from the heart and consists of 3 layers: endothelium, middle layer, and outer layer
|
Arteries
|
|
|
Small arteries composed mostly of smooth muscle
|
Arterioles
|
|
|
Is the exchange and An extremely narrow, microscopic tube w/a wall composed only of endothelium w/a basement membrane. Arterioles branch into them.
|
Capillaries
|
|
|
Goes to the heart. Consist of Venules
|
Veins
|
|
|
Small veins that drain blood from the capillaries and then join to form a vein.
|
Venules
|
|
|
Generate blood pressure, transport blood, Exchange of nutrients and wastes at the capillaries, and regulates blood flow as needed
|
Cardiovascular System
|
|
|
What is the main pathway of blood in the body?
|
Hears, arteries, arterioles, capillaries, venules, veins, back to the heart
|
|
|
A muscular organ consisting of mostly cardiac tissue.
|
Heart
|
|
|
Cardiac Tissue
|
Myocardium
|
|
|
A sac that surrounds the heart
|
Pericardium
|
|
|
What are the four chambers the heart consist of?
|
2 atrium, and 2 ventricle
|
|
|
What are the two cardiovascular pathways in the body?
|
Pulmonary and systematic circuit
|
|
|
The right side of the body that brings blood from the body to the heart and to the lungs
|
Pulmonary circuit
|
|
|
The left side of the body that brings blood to the entire body to deliver nutrients and rid it of wastes
|
Systematic circuit
|
|
|
How does the heartbeat occur?
|
During Systole, the atria contract together followed by the ventricles contracting together. This is followed by the Diastole which is the resting phase.
|
|
|
On average, how many times do the cardiac cycle occur?
|
about 70 times/minute
|
|
|
A record of the electrical changes in the heart muscle during the cardiac cycle
|
Electrocardiogram (ECG)
|
|
|
The contracting of of the ventricles
|
QRS Complex
|
|
|
The recovery of the ventricles
|
T Wave
|
|
|
The pressure against a blood vessel wall
|
Blood pressure
|
|
|
What is the average blood pressure
|
120/80
|
|
|
What is blood pressure controlled by?
|
arterioles
|
|
|
What is high blood pressure called? Low?
|
Hypertension, Hypotension
|
|
|
If blood pressure is so low in the veins, why does the blood flow increase?
|
They have help by skeletal muscle contraction, breathing, and valves
|
|
|
A system that brings blood from the digestive tract rich in amino acids, and glucose to the liver
|
Hepatic Portal System
|
|
|
What is the most common death in the Western World?
|
Cardiovascular Disease
|
|
|
A cardiovascular disorder that conssists of high blood pressure that can lead to a heart attack, stroke, or kidney failure.
|
Hypertension disorder
|
|
|
A build up of plaque in blood vessels. It is associated with a stroke, heart attack, and aneurysm
|
Atherosclerosis
|
|
|
Occurs when a craniel artery is blocked and bursts. Part of the brain dies due to lack of oxygen. Also known as Cerebrovascular accident.
|
Stroke
|
|
|
Part of the heart dies due to lack of oxygen. Also known as myocardial infarction
|
Heart attack
|
|
|
A ballooning of a blood vessel
|
Aneurysm
|
