Functions of Blood Flashcards
What role does blood play in nutrient transport?
Absorbs nutrients from the digestive system and carries them to the liver.
How does blood interact with the respiratory system?
Picks up gases (like oxygen) from the respiratory system and transports them.
What waste products does blood help remove?
removes waste products from cellular respiration
What is the role of blood in hormone transportation?
Blood delivers hormones from endocrine glands to the organs
How does heat transfer occur in the body through blood?
Heat travels from hot to cold areas within the body.
What happens to blood vessels when body temperature is too high?
Vasodilation occurs, where blood vessels expand near the skin to release heat.
What is vasodilation, and how does it help with temperature regulation?
Vasodilation is the expansion of blood vessels near the skin, allowing more blood flow to the surface to cool the body.
How does the body conserve heat when it’s too cold?
Vasoconstriction occurs, where blood vessels near the skin decrease in diameter to conserve heat.
How does shivering help regulate body temperature?
Shivering produces heat.
