Study Notes
Plants
- Require water and air (gases) for survival and growth.
- Manufacture glucose during photosynthesis, which serves as a sugar and primary energy source for growth.
- Stomata in leaves allow gases to enter the plant, facilitating photosynthesis.
Humans
- Obtain energy by consuming food, which is chewed, swallowed, and digested.
- Digestion converts food into nutrients that are absorbed into the bloodstream.
- Air is inhaled through the nose and mouth, traveling to the lungs where oxygen enters the bloodstream.
Human Circulatory System
- Transports oxygen and nutrients via blood to body cells.
- Comprises the heart and blood vessels.
Heart
- Functions as a pump, circulating blood to body cells and receiving it back.
- Contains four chambers:
- Two atria (upper chambers)
- Two ventricles (lower chambers)
Blood Vessels
-
Arteries:
- Carry oxygen-rich and nutrient-rich blood from the heart to body cells.
-
Veins:
- Transport carbon dioxide-rich and nutrient-poor blood back to the heart, then out to lungs for oxygenation.
-
Blood Capillaries:
- Microscopic vessels connecting arteries and veins, exchanging nutrients and waste at the cellular level.
Blood
- A fluid that circulates in one direction between arteries and veins, ensuring efficient transport of oxygen and nutrients.
