Anabolism
Process of building up large proteins from small protein pieces called amino acids. Ana- means up, bol means to cast, and -ism is a process
Process of building up large proteins from small protein pieces called amino acids.
Anabolism
Process whereby complex nutrients are broken down to simpler substances and energy is released
Catabolism
Catabolism

Structure surrounding and protecting the cell. It determines what enters and leaves the cell.
Cell membrane
Cell membrane
Structure surrounding and protecting the cell. It determines what enters and leaves the cell.
Rod shaped structures in the nucleus that contain regions of DNA called genes.
Chromosomes ((There are 46 chromosomes (23 pairs) in every cell, except for the egg and sperm cells, which contain only 23 individual, unpaired chromosomes.))
Chromosomes
Rod shaped structures in the nucleus that contain regions of DNA called genes.
Cytoplasm
All of the material that is outside the nucleus, and yet contained within the cell membrane

Mitochondria
Rod-shaped structures in the cytoplasm that provide the principal source of energy (mini power plants) for the cell. *think MIGHTY mitochondria
Catabolism is the process that occurs in mitochondria.
Rod-shaped structures in the cytoplasm that provide the principal source of energy (mini power plants) for the cell. Catabolism occurs here.

Specialist in the study of tissues
Larynx
Voice box; located above the trachea
Pharynx
Throat. The pharynx serves as the common passageway for food (mouth to esophagus) and air (most to trachea).

Endocrine gland at the base of the brain
Thyroid gland
Endocrine gland that surrounds the trachea in the neck
Trachea
Windpipe (tube leading from the throat and larynx to the bronchial tubes)
Ureter
One of two tubes each leading from a single kidney to the urinary bladder *hint: ureter has two e’s, and there are two ureters
Urethra
Tube from the urinary bladder to the outside of the body
* hint: urethra has one e, and there is only one urethra
Uterus
Womb; the organ that holds the embryo/fetus as it develops
Viscera
Internal organs in the main cavities of the body, especially in the abdomen
Abdominal cavity
Space below the chest containing organs, such as the liver, stomach gallbladder and intestines; also called the abdomen or peritoneal cavity
