Circulation Flashcards
Major circulatory systems
- Cardiopulmonary
- Systemic circulation
Specialized circulatory systems
- Coronary
- Portal
- Fetal circulation
Red blood is
Oxygenated blood
Blue blood is
Deoxygenated blood
Coronary circulation
Bring red blood to the heart muscle
Portal circulation
- A branch of the general circulation
- Digestive organs (pancreas, stomach, small intestine, colon, spleen) spills blood into hepatic portal vein which goes to the liver
- Blue blood leaves the livers to go the hepatic vein
During fetal circulation through what do the mother and baby exchange nutrients
The placenta
Do the blood of the mother and baby mix
No they do not
What are three blood vessels
- Arteries
- Capillaries
- Veins
What is the smallest blood vessel
The capillaries
Arteries
Carry red blood away from the heart to the capillaries
What carries blue blood to the lungs
Pulmonary arteries
What does the capillaries transport
O2, CO2, nutrients, waste
What do the veins do
Carry blue blood from the capillaries to the heart
What carries red blood to the heart
Pulmonary veins
What is the largest artery
Aorta
What is the largest vein
Vena Cava
When does pressure change occur and what does it help do
Occurs when we breath and it brings back venous blood to the heart
Aneurysm
Ballooning out and thinning of the artery walls which is caused by weakening of the blood vessel
Arteriosclerosis
Thickening of the artery walls also known as hardening
Atherosclerosis
Build up of fat along the artery walls
What do both arteriosclerosis and atherosclerosis result in
Narrowing of the vessels
Gangrene
Death of tissue due to insufficient blood supply
Varicose
Swollen vein due to insufficient blood flow
Peripheral vascular disease (PVD)
Blockage of arteries usually in legs
Hypertension
High blood pressure which is higher than 120/80
Hypotension
Low blood pressure which is lower than 90/60
Transient ischemic attack (TIA)
Temporary interruption of blood flow to the brain
Cerebral vascular accident (CVA)
Also known as a stroke which is a sudden interruption of blood flow to the brain
Aphasia
Loss of speech
Dysphasia
Difficulty in speech
