What is the function of the liver?
The liver processes nutrients from the digestive system, detoxifies harmful substances, and produces bile.
The liver also plays a role in metabolism and regulation of blood sugar levels.
What is the function of the pancreas?
The pancreas produces digestive enzymes and hormones, including insulin and glucagon.
Insulin regulates blood sugar levels, while glucagon raises blood sugar levels.
What is the function of the small intestine?
The small intestine is responsible for the majority of digestion and nutrient absorption.
It consists of three parts: duodenum, jejunum, and ileum.
What is the function of the large intestine?
The large intestine absorbs water and electrolytes, and compacts waste for elimination.
It also houses beneficial bacteria that aid in digestion.
What is the function of the stomach?
The stomach breaks down food using acid and enzymes, turning it into a semi-liquid substance called chyme.
The stomach also plays a role in the initial stages of protein digestion.
What is the function of digestion?
Digestion breaks down food into smaller molecules for absorption into the bloodstream.
It involves both mechanical and chemical processes.
What is the function of the circulatory system?
The circulatory system transports blood, nutrients, gases, and wastes throughout the body.
It includes the heart, blood vessels, and blood.
What is the function of plasma?
Plasma is the liquid component of blood that carries cells, nutrients, hormones, and waste products.
It makes up about 55% of total blood volume.
What is the function of platelets?
Platelets are involved in blood clotting and help prevent bleeding.
They are essential for the repair of damaged blood vessels.
What is the function of villi?
Villi are small finger-like projections in the small intestine that increase surface area for absorption of nutrients.
They contain microvilli, which further enhance absorption.
