Transcript of The Circulatory System

The Circulatory System


- forms skin, blood vessels
- heals wounds
- repairs bones and teeth
- scurvy is a form of deficiency
Vitamin D

- maintains strong bones
- controls blood pressure
Vitamin D
Found in:
- fatty fish
- eggs, milk
- cereals
- 90% made when body is exposed to sunlight
Vitamin K
- fat soluble
- clots blood
- can be made up of K1 0r K2
- K1 made by plants
- K2 made in gastrointestinal
tract
Vitamin K
Found in:
- green leafy vegetables
- beans and soybeans
- meat, eggs
- not used as a supplement

Vitamin C
- water soluble
- antioxidant
- protects from free radicals
Vitamin C
Highest sources found in:
- citrus fruits
- cantaloupe
- mangoes
- broccoli, peppers
- tomatoes
- all fruits + veggies have some vitamin C
- fat soluble
- fights off viruses
Hemophilia
-Rare bleeding disorder
-Causes blood to not clot normally because of decreased amounts of clotting factor


Effects
-Bleed for a longer time after injury
-More likely to have internal bleeding
Causes
-Inherited genetically
-Can be (rarely) aquired
-Body forms anti-bodies that attack clotting factor
-Can cause clotting factor not to work
Clotting Factor
-Protein needed for blood to clot
-Works together with platelets
Angina
-Chest pain occurring when heart doesn't get enough blood
-Can be sign of coronary heart disease
Effects
-Feels like pressure/squeezing of the chest
-Pain can also occur in shoulders, neck, arms, jaw, or back
-Another pain can feel like indigestion
Types of Angina
Stable Angina
-Most common type
-Occurs when heart is working harder than usual
-Has regular pattern
-Heart attack more likely in future
Unstable Angina
-Doesn't follow pattern
-More severe and pain occurs more often than stable angina
-Rest/medicine may not relieve pain
-Dangerous and requires emergency treatment
-Heart attack may occur soon
Microvascular Angina
-Caused by spasms in walls of very small arterial blood vessels
-More severe and lasts longer than other types
Variant (Prinzmetal's) Angina
-Rare
-Caused by spasm in coronary artery
-Occurs during rest
-Usually very severe
The Heart
Circulates blood through body
Three outer layers
Pericardium: heart sac
Myocardium: muscle layer
Endocardium: inner lining
Atria
Above the ventricle
Receive blood from superior and inferior vena cava
Drives blood down to ventricles
Ventricles
Right ventricle
Gets blood from right atria through tricuspid valve
Left Ventricle
Gets blood from left atria through mitral valve

Ventricles pump blood back into the system
Blood Vessels
Three types
Veins
Carry blood to the heart
Capillaries
Connect veins to arteries
Arteries
Carry blood away from the heart
Aorta
Biggest artery
Four parts
Ascending aorta
Aortic arch
Descending thoracic arch
Abdominal arch
Red Blood Cells
Made in bone marrow
Released into cell after seven days

Circulatory System by Ruth Bjorklund
Vitamins
- Vitamin D

- Vitamin K

- Vitamin C
Example (Right side of the heart)
Michelle Dubovitsky
Blood enters atria through inferior and superior vena cava

Blood flows into right ventricle through tricuspid tube

Blood leaves heart through pulmonic valve into pulmonary artery

Blood is oxegynated in lungs and completes its cycle

FUNCTIONS
RESPIRATION

gives O2, takes CO2 from cells
NUTRITION
carries nutrients through blood
WASTE REMOVAL
carries cellular waste

TRANSPORT OF BLOOD
THROUGH HEART
kaitlyn wang
BLOOD
PROVIDES TO CELLS
nutrition
oxygen
waste removal
what makes up blood?
PLASMA
Half of content of blood
Contains proteins
Aid in clotting
Transporting substances
Contains nutrients like glucose
Makes blood thick
BLOOD CELLS
red carry oxygen
FUN FACT: red because hemoglobin
white fight infections
platelets help clotting

BLOOD VESSELS (CONT.)
Arteries (red)
Oxygen rich blood
Veins (blue)
Oxygen poor blood
kaitlyn wang
BLOOD FLOW
Pulmonary
Blood away from heart to lungs
Back to heart
CO2 released from blood
O2 absorbed
Systemic
Arteries, veins, vessels
Transports blood
From heart
To organs and tissues
two independent systems that work together
kaitlyn wang
FUN FACTS
In one day:
100,000 heart beats
60,000 miles of branching vessels
Power output of heart
1-5 watts per minute
Per day, could drive a truck 20 miles

Pulmonary Artery
Taylor Balfour
Transports deoxygenated blood to the lungs
Main artery splits into right and left
deliver blood to each lung
Begins at right ventricle
Other Blood Vessels
Superior/Inferior vena cava
Superior-carries deoxygenated blood to right atria
Inferior-carries deoxygenated blood to right ventricle
Coronary Artery
Supply blood to heart muscle
