BODY SYSTEMS TO CELLS

Hepatocytes

Hepatocytes

________ are a type of cell that may be found in the liver.

Exocytosis

________ is the process by which secretions are discharged; a vesicle fuses with the cell membrane and then releases its contents.

Microfilaments

________ and microtubules make up the cytoskeleton, which is the internal framework of the cell.

sac

A(n) ________ that is secreted at the cell membrane that includes a variety of compounds that are produced by the cell, such as enzymes.

Tissues

________ are made up of groups of cells.

blood vessel

A(n) ________ that has numerous pores that enable the blood to exchange oxygen and nutrients with the surrounding tissue.

membrane

A(n) ________ consisting of two layers, each of which contains pores through which substances can travel.

Hepatocellular lobules

________ are the structural- functional units that make up the liver.

body system

is understood to be a collection of organs and other body elements that work together to accomplish one primary function.

digestive system

One of the body's systems that is particularly well understood is the

liver

The _ is the body's largest internal organ, weighing an average of 31/3 pounds (1.5 kilograms) in adults.

gallbladder

which is a tiny sac located directly under the liver's right end.

Kupffer cell

This type of white blood cell is exclusive to the liver and is also known as a hepatic macrophage.

Cells

serve as the fundamental living unit of all tissues in the body.

Bile canaliculus

The bile duct's most smallest branch, which winds its way through the hepatocytes.

Sinusoid

A blood vessel that has numerous pores that enable the blood to exchange oxygen and nutrients with the surrounding tissue.

Bile duct

Drains the bile fluid, which is produced by the hepatocytes, into the canaliculi.

Microvilli

Some cells have projections, which serve to enhance the total surface area of the cell.

Centriole

Two cylinders made up of tubules, both of which are necessary for reproduction.

Microtubule

Constitutes a component of the cytoskeleton and contributes to the movement of constituents within the cytoplasm.

Mitochondrion

The location in the cell where digestion of sugar and fat takes place; the source of cellular energy

Vacuole

A sac that collects and carries water, waste, and the materials that have been ingested.
