23-1 And 23-2 Flashcards
What is the size of your heart
Fist
What are the five parts of the cardiovascular system
Heart blood arteries veins capillaries
Where is the heart
Center of the chest below the sternum
What type of tissue is the heart made of
Cardiac muscle
What type of blood is artery
Oxygenated
What is the universal type of blood
O
What’s the difference between antigen and antibody
Antigen on the cell and determines blood type
Antibody floating around the cell and kill pathogens
What’s the difference between superior and inferior vena cava
Superior has deoxygenated from upper body to heart and inferior carries deoxygenated blood from lower body to heart
What do arteries do
Send blood away from heart to body
What does the right atrium do
It pumps blood into aorta to be carried to body
Veins do
Carry blood to heart
Capillaries do
Carry oxygen to cells and takes away co2 and wastes
Aorta
Carries oxygenated blood to body
Right atrium
Collects deox from the body
Pulmonary valve
Prevents blood from going to right atrium
Right ventricle
Pumps blood to pulmonary artery
Pulmonary artery
Carries deoxygenated blood to the lungs
Pulmonary vein
Oxygenated blood to the heart from the lungs
Left atrium
Collects oxygenated blood from lungs
Aortic valve
Prevents blood from going into left ventricle
Left ventricle
Pumps blood to body
The superior and inferior do what
Bring deox blood to right atrium
Right atrium pumps into
Right ventricle
Right ventricle does what
Pumps doex blood to pulmonary artery and ten to lungs
What happens after the blood gets oxygenated
Exits lungs and goes to left atrium through pulmonary vein
Left atrium does what
Pumps to left ventricle
Left ventricle pumps to
Aorta
What does aorta do
Carries blood to body then goes to arteries that goes to capillary that exchanges materials
After discussion the blood goes where
Blood returns to veins then to vena cava and then heart
Red blood cells
- oxygen
- hemoglobin with iron
- no nucleus
- lives for 120 days
White blood cells
- kill pathogens
- make antibodies
- Have nucleus
- can leave bloodstream
- 1 for every 500 red blood cells
Platelets
- Clot bleeding
- fibers pull
- lack in hemophiliacs
Plasma has
Nutrient water hormones proteins but gets rid of waste
Pulmonary circulation
Lung with heart
Systematic circulation
Body with heart
Atherosclerosis
Cholesterol builds up and blocks blood flow
Hypertension
Abnormally high heart pressure
Stroke
Blood vessel in brain gets stuck
Heart attack
Heart muscle cells are die or heart muscle is damaged
Heart failure
Cannot pump enough blood to support body
Hemoglobin
Oxygen carrying protein
Systolic pressure
Ventricle contract
Diastolic pressure
Ventricles relax
