LAB 2

Structural and functional unit of living things

Cells

Example of an organ in the human body

Small intestine

System responsible for maintaining homeostasis via rapid electrical transmission

Nervous system

Organs that are part of the urinary system

Kidneys, ureters, bladder, urethra

Muscle that separates the thoracic and abdominal cavities

Diaphragm

Two organ systems primarily involved in maintaining homeostasis

Nervous system and endocrine system

Function of the kidneys in the urinary system

Filter blood and produce urine

Functions of the endocrine system

Uses hormones for slower communication within the body

Type of tissue that lines organs and cavities

Epithelial tissue

Type of muscle involved in moving blood

Cardiac muscle

Cells produced by the testes

Sperms

Cells produced by the ovaries

Ovum (Eggs)

Four primary tissue types in the human body

Epithelial, connective, muscle, nervous

Definition of an organ

A structure made up of two or more types of tissues

Effect of thymectomy on the immune system

Decreased maturation of T cells due to lack of thymus hormones

Importance of the spleen in the immune system

Filters blood, removes microbes and debris

Role of pancreatic islets

Produce hormones such as insulin (endocrine function)

Combining lymphatic and endocrine systems

Thymus gland contributes to both systems

Two organ systems involved in acid-base balance

Respiratory system and urinary system

Function of the rib cage in relation to the cardiovascular system

Protects the heart
