Study Notes
Circulatory System
- Responsible for the transportation of blood throughout the body.
- The heart acts as a pump, circulating blood to deliver oxygen and nutrients.
- Arteries are large blood vessels that transport oxygen-rich blood away from the heart to the tissues and organs.
- Veins are smaller blood vessels that return deoxygenated blood back to the heart.
Digestive System
- Facilitates the breakdown of food and the absorption of nutrients necessary for the body’s energy and functioning.
- The mouth is the initial entry point for food, where it is chewed and mixed with saliva.
- The stomach is where a significant portion of digestion occurs, utilizing acid and enzymes to break down food.
- The small intestine is responsible for further breaking down food and absorbing the majority of nutrients into the bloodstream.
- The large intestine primarily absorbs water from indigestible food matter, forming waste for excretion.
Excretory System
- Functions to eliminate waste products resulting from metabolic processes within the body.
- Excretion refers to the process by which the body expels these waste products.
- Kidneys play a crucial role in filtering waste substances and excess water from the blood, regulating fluid balance, and maintaining the body's electrolyte levels.
