collects from tissue spaces the fluid that is filtered out of the blood vessels and conveys it back to the vascular system.
lymphatic system
transports blood
blood vascular system
What does the blood vascular system consist of?
the heart and 2 circulatory systems that branch out and return blood back to the heart.
What are the 2 circulatory systems?
pulmonary cirulation and systemic circulation
Which circulatory system is shorter and which is longer.
pulmonary is shorter, systemic longer
discharges carbon dioxide and takes up oxygen
pulmonary circulatory system
heart serves as pumping mechanism to keep blood in constant circulation through out system
systemic circulation
conveys blood from the heart
conveys blood to the heart
arises from heart for pulmonary circulation
pulmonary artery
arises from heart for systemic circulation
Arteries diminish into ______, then _______, and then reversed to form ________ and then ________.
arterioles, capillaries, venules, veins
The systemic veins have superficial and deep vessels opening into the heart, what are these

from the heart to lungs
Where does the superior vena cava send blood to?
head and arms
Where does the inferior vena cava send blood to?
trunk and legs
Where does the aorta go to?
all parts of the body
receives blood from the body and pumps it through the pulmonary artery to the lungs where it picks up fresh oxygen
right heart
receives oxygen full blood from the lungs and pumps it through the aorta to the body
left heart
inside lining of the heart
heart muscle?
bag of tissue surrounding heart
Central organ of blood vascular system and functions as a pump to keep the blood in circulation?
Where is the heart located?
left of the median sagittal plane, apex resting on diaphragm
muscular wall of heart?
narrow fluid containing space between the 2 walls of the sac.
Pericardial Sac
Lines inside chambers of heart?
adheres the heart
right and left distributing chambers
The left ventricle pumps oxygenated blood into where?
right and left, receiving chambers
tricuspid, mitral
What supplies blood to the myocardium?
right and left main arteries
Where in the heart does the aorta come from, and what does it divide into?
superior portion of the left ventricle, divides into the right and left common iliac arteries, internal and external iliac arteries, and femoral artery.l
what arteries branch off the aorta to all parts of the body.
Oxygenated blood leaves the left ventricle by way of aorta and is carried to all parts of the body except where?
Deoxygenated blood is collected by the veins and returned to where?
right atrium
involves the travel of blood from the pulmonary arteries to the lungs and back.
Pulmonary circulation
What do veins have that arteries do not?
what does a veinogram look for?
embolus or thrombus
Fatty plaque could cause loss of blood to myocardium which could result in what?
Heart attack
A blockage in artery could cause what?
heart attack
If you catheterize the heart, what does the problem have to do with?
chambers of the heart
if you take a blood vessel from another part of the body and use it for the heart, what is it called?
systole is?
pumping blood
relaxing, receiving blood
what is normal for systole and diastole?
120 systole

180 diastole
complete circulation of blood through both systemic and pulmonary circuits requires about how much time and how many heart beats?
23 seconds, and an average of 27 heartbeats
when it comes to the heart why does a simpe injection not work, and what kind of injection must it be?
it dilutes the medication, interarteriole
how is lymph moved?
extrinsic pressure from surrounding organ and muscles
What does the lymphatic system do?
manufactures lymphocytes (white blood cells) and antibodies. Filtration of carbon particles, bacteria, and malignant cells occur in the system.
Lymph is clear, colorless and is continually produced by what?
tissue fluid
microscopic vessels that are located in the intracellular spaces and in various organs.
collecting vessels similar to veins in structure and contain valves to ensure movement towards the heart
Where do the lymphatic vessels drain into?
thoracic duct and subclavian vein
Right and Left main are what?
Coronary arteries
What are the 2 types of lymph vessels?
capillaries, and lymphatics
lymph vessels empty into what and is maintained there for how long?
lymph nodes, 3 to 4 weeks
What are the functions of of lymphy nodes?
defense functions, (filtration and phagocytosis of cancerous cells**tumors can block these and cause swelling. Production of lymphocytes.
radiologic exam of vascular structures in the body after administration of contrast media.

Where is it injected?
deep vein thrombosis

veins of feet
What is a lower limb arteriogram used for?
