Soc16: Structure Of The Blood Flashcards
Capilleries
Any of the tiny blood vessels that connect the smallest arteries (arterioles) to the smallest veins (venules).
Veins
Veins are an important part of our circulatory system. They are responsible for returning deoxygenated blood back to the heart after arteries carry blood out.
Arteries
A vessel that carries blood high in oxygen content away from the heart to the farthest reaches of the body. Since blood in arteries is usually full of oxygen, the hemoglobin in the red blood cells is oxygenated
Vascular shunting
Process that increases blood flow to active areas during exercise by diverting blood away from inactive areas ; achieved by vasodilation and vasoconstruction
Immune system
The structures and processes in your body that stop disease
Serotonin
Hormone that triggers the clotting process
Thrombokinase
Substance involved in blood clotting
Plasma
The fluid part of blood
Erythrocyte
Red blood cells
Haemoglobin
A red protein in
Cardio-respiratory system
The interaction of the heart and lungs to supply oxygen to muscles during exercise
Cardiovascular
To do with the heart, blood and blood vessels together
Vasodilation
When veins swell up or dilate
Vasoconstriction
When veins shrink down, narrowing of the blood vessel to decrease blood flow
Cusp
A triangular fold or flap of a heart valve
