3.1 Building Blocks of the Human Body
Protoplasm
A gel-like substance containing water, salt and nutrients obtained from food. Cells are composed of this.
System
A group of body structures and/or organs that, together, perform one or more vital function for the body.
Reproductive
Allows living organisms to procreate others of its kind.
Liquid tissue
Carries food, waste products and hormones.
Circulatory
Circulates blood through the body.
Heart
Circulates the blood.
Muscular tissue
Contracts when stimulated to produce motion.
Eyes
Control vision.
Brain
Controls all body functions.
Respiratory
Controls breathing of the body.
Endocrine
Controls growth and general health and reproduction of the body.
Integumentary
Controls the sebaceous (oil) and sudoriferous (sweat) glands.
Nerve tissue
Coordinates body functions in addition to carrying messages to and from the brain and spinal chord.
Stomach and intestines
Digest food.
Kidneys
Eliminate water and waste products.
Excratory
Eliminates waste from the body.
Tissues
Groups of cells of the same kind.
Muscular
Moves the body.
Cyroplasm
Production department of the cell where most of the cell's activities take place.
Skeletal
Provides framework of the body.
Liver
Removes the toxic byproducts of digestion.
Nervous
Sends and receives body messages.
Organs
Separate body structures that perform specific functions. They are composed of two or more different tissues.
Digestive
Supplies food to the body.
Lungs
Supply the blood with oxygen.
Connective tissue
Supports, protects and holds the body together.
Cells
The basic units of living matter.
Skin
The body's largest organ. Forms the external protective layer of the body.
Metabolism
The chemical process in which cells receive nutrients (food) for cell growth and reproduction.
Nucleus
The control center of cell activities.
Cell membrane
The outer surface of the cell which encloses the protoplasm.
Catabolism
The process of breaking down larger molecules or substances into smaller ones.
Anabolism
The process of building up larger molecules from smaller ones.
Gross anatomy
The study of structures that can be seen with the naked eye.
Histology/ Microscopic anatomy
The study of structures too small to be seen except through a microscope.
Physiology
The study of the functions these organs and systems perform.
Anatomy
The sudy of organs and systems of the body.
Epithelial
Tissue that covers and protects body surfaces and internal organs.
