- 24. A one-way valve in the heart, located between the left atrium and the left ventricle, that controls blood flow from the lungs to the rest of the body.
- 28. Any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body.
- 29. A device for controlling the passage of fluid or air through a pipe, duct, etc., especially an automatic device allowing movement in one direction only.
- 32. A watery, typically yellowish fluid stored in the bladder and discharged through the urethra.
- 33. A female reproductive organ in which ova or eggs are produced, present in humans and other vertebrates as a pair

Down
- 1. Each of the functional units in the kidney, consisting of a glomerulus and its associated tubule, through which the glomerular filtrate passes before emerging as urine
- 2. The duct by which urine is conveyed out of the body from the bladder
- 3. An organ which produces spermatozoa (male reproductive cells).
- 4. any of the major air passages of the lungs which diverge from the windpipe
- 6. A large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes
- 7. The process of taking air into and expelling it from the lungs
- 8. A cluster of nerve endings, spores, or small blood vessels, in particular a cluster of capillaries around the end of a kidney tubule, where waste products are filtered from the blood.
- 9. Any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart
