Lipids are digested into fatty acids and glycerol molecules. The glycerol molecules are used in glycolysis and the fatty acids are oxidized into acetyl CoA, which are used in the Krebs Cycle

During gas exchange, oxygen and carbon dioxide move between blood, air, and tissues due to partial pressure gradients

Urine is the filtrate produced and excreted by the urinary system

A zygote is an oocyte that has been fertilized by a spermatozoa. Single celled zygotes divide and develop into multicellular babies

Unlike the production of oocytes, the production of spermatozoa begins at puberty and continues throughout a males life

A key role of the cervix is to secrete mucus during intercourse to help facilitate sperm movement through the reproductive tract

Oviducts serve as corridors for oocytes to travel from the ovaries to the uterus

Menopause is the cessation of the menstrual cycle

The relative partial pressure of oxygen in the blood coming to the lungs from the heart is lower than the partial pressure of carbon dioxide
