Question

Match the following system with its function.
Skeletal
Reproductive
Respiratory
Endocrine
Digestive
Excretory

Answer 1

Skeletal — supports body, protects organs, enables movement (with muscles), stores minerals (calcium) and produces blood cells (bone marrow).

Reproductive — produces gametes (sperm/eggs), secretes sex hormones, enables fertilization and reproduction (development/maintenance of offspring).

Respiratory — exchanges gases (O2 in, CO2 out), helps regulate blood pH and assists in vocalization/olfaction.

Endocrine — secretes hormones that regulate metabolism, growth, development, reproduction and homeostasis.

Digestive — ingests, breaks down (digests) food, absorbs nutrients and eliminates solid waste.

Excretory (urinary) — removes metabolic wastes, regulates water, electrolyte and acid–base balance (kidneys, ureters, bladder, urethra).
