Blood Flow
Blood vessels that carry blood away from the body
Arteries
Smallest and most numerous blood vessels
Capillaries
What can happen if you leave coronary artery disease untreated?
HEART ATTACK!!!!!
If a person has grossly swollen thigh/leg and is is diagnosed with a large tumor in her lower pelvis. The tumor has compressed the lymphatic vessels, thereby impairing the drainage of lymph; impaired lymph drainage causes the accumulation of fluid in the interstitium
Edema
What are the organs of the lymphatic system?
Lymph nodes, thymus gland, and spleen.
What carries deoxygenated blood to the heart?
Veins
The capillaries are called exchanged vessels because they allow for exchange between what thing?
Nutrients and waste
What is DVT and where in the body does it usually happen?
Blood clots form in the veins and usually happen in the legs
If a patient takes a drug that causes Veno dilation (widening of the veins). This causes blood pools in veins, less blood return to heart, myocardial contraction/cardiac output decreases, hypotension(decreases in BP). If a patient attempts to change positions quickly, as in rising from supine position to a standing position insufficient blood to brain causes dizziness, fainting and falling. This series of events if called what?
Postural Hypotension also known as orthostatic hypotension
Which artery feeds the leg?
Common iliac
Which of the following blood vessels runs parallel to the femoral artery?
Femoral artery
What is connected to capillaries?
Arteries and veins
What is the insufficient blood supply to the tissues or organ?
Ischemia
In an attempt to rid the body of all cancer cells, the surgeon removes the breast and associated axillary lymph nodes. The lymph nodes are then biopsied; further treatment often depends on how many of the lymph nodes are positive. Removal of the axillary lymph nodes frequently impairs lymphatic drainage.
The woman developed edema of the affected arm and shoulder. What is this called?
Lymphedema
Baroreceptors are located where?
Aortic arch and carotid sinus
Is the blood vessel carrying blood toward the heart an afferent or efferent blood vessel?
Afferent blood vessel.
What are the 3 characteristics that make the capillaries good exchange vessels?
Thin capillary walls, large numbers of capillaries, and slow blood flow.
The excess filtration of water into the lungs is called? Usually resulting in impaired oxygen.
Pulmonary edema
Patient complains of leg pain, heaviness and aching, her legs look swollen, bulging and veins are clearly visible. She states that she does stand for long periods. When veins are distended, twisted, dark purple and swollen due to pressure they can become damaged or weak. What are these veins called?
Varicose veins
How does the brain drain blood?
Jugular Veins
There is one exception to this rule: the pulomonary arteries (usually carries oxygenated blood) but these arteries carry deoxygenated blood when?
These arteries carry deoxygenated blood from the heart to the lungs, where it is oxygenated.
What forces are used to move water, nutrients, and waste in and out of the capillaries?
Diffusion and filtration osmosis
What is the abnormal bulging or ballooning of the walls of blood vessels especially the arteries?
Aneurysm
A 44 year old patient diagnosed with aplastic anemia. Goes in for a procedure receiving an allogenic bone marrow transplant from a donor 28 days ago. Patient presents with widespread skin rash, persistent diarrhea, and jaundice.
What immune disease would this be?
Graft-versus-host disease
A interconnected group of arteries at the base of the brain, a crucial backup system for blood flow to the brain.
Circle of Willis
