SCIENCE Circulation And Respiration Flashcards
What are the functions of the cardiovascular system?
- remove waste products
- gaseous exchange
- boosts immunity
- distributes blood through blood vessels
This part of the cycle carries oxygen depleted blood away from the heart,to the lungs and back to the heart
Pulmonary circulation
This is the part that carries oxygenated blood away from the heart and to other parts of the body
Systemic circulation
This type of circulation provides the heart with oxygenated blood so it can function properly
Cornonary circulation
Liquid portion of the blood that contains:
Clotting factors
Hormones
Antibodies
Dissolved gases
Nutrients
Wastes
Plasma
*Carry hemoglobin and oxygen
* live approximately 120 days
Erythrocytes/ red blood cells
- fight infection
Leukocytes/ white blood cells
*Are cell fragments that are formed in the bone marrow
* responsible for blood clotting by sticking together via protein dibers called fibrin
Thrombocytes/ platelets
- largest and thickest type of blood vessels
- carry oxygenated blood away from the cappillaries
Arteries
- carry deoxygenated blood away from cappillaries back to the heart
- veins conatin and muscukar layer but less elastic and muscular then arteries
Veins
- the smallest blood vessels
- is where the exchange of nutrients and gases occurs
Capillaries
- size of a closed fist
- APEX: blunt rounded point of cone
- BASE: flat part at opposite of end of cone
Heart
Located in the thoracic cavity
Heart
Protects the heart( a double-walled sac encloses the heart)
Pericardium
One of the four chambers of the heart * receiving chambers
2 atria/ auricles
