Chapter 2- BODY AS A WHOLE LoM Flashcards
Anabolism
The process of building up large proteins from small protein pieces called amino acids
Catabolism
The process whereby complex nutrients are broken down to simpler substances and energy is released
Cell membrane
Structure surrounding and protecting the cell. It determines what enters and what leaves
Chromosomes
Rod-shaped structures in the nucleus that contain regions of DNA called genes. There are 46 chromosomes (23 pairs) in every cell except for egg and sperm cell
Cytoplasm
All of the material that is outside the nucleus and yet contained within the cell membrane
DNA
Chemical found within each chromosome. Arranged like a sequence of recipes in code, it directs the activities of the cell
Endoplasmic reticulum
Network of canals within the cytoplasm of the cell. Here, large proteins are made from smaller protein pieces.
Genes
Regions of DNA within each chromosome
Karyotype
Picture of chromosomes in the nucleus of the cell. The chromosomes are arranged in numerical order to determine their number and structure.
Metabolism
Total of the chemical processes in a cell.
Mitochondria
Rod-shaped structures in the cytoplasm that provide the principal source of energy for the cell. Catabolism occurs in mitochondria.
Digestive organs
Mouth, pharynx, esophagus, stomach, intestines, liver, gallbladder, pancreas
Urinary or excretory
Kidneys, ureters, urinary bladder, urethra
Respiratory
Nose, pharynx, larynx, trachea, bronchial tubes, lungs
Reproductive
Female: ovaries, fallopian tubes, uterus, vagina, mammary glands
Male: testes and associated tubes, urethra, penis, prostate gland
Endocrine
Thyroid gland (in the neck), pituitary gland (base of brain), sex glands, adrenal glands, pancreas, parathyroid glands
Nervous organs
Brain, spinal cord, nerves, collection of nerves
Circulatory organs
Heart, blood vessels (arteries, veins, capillaries), lymphatic vessels and nodes, spleen, thymus gland
Musculoskeletal
Muscles, bones and joints
Skin and sense organs
Skin, hair, nails, sweat glands, sebaceous glands; eye, ear, nose and tongue
Adipose tissue
Collection of fat cells
Cartilage
Flexible connective tissue often attached to bones at joints
Epithelial cells
Skin cells that cover the outside of the body and line internal surfaces of organs

urethra
tube from the urinary bladder to the outside of the body
uterus
womb; the organ that holds the embryo/fetus as it deveoops
