From the vagina, the sperm will swim through the cervix into the uterus and find the egg in the fallopian tube - -true The pleurae and pleural fluid can help prevent the spread of pulmonary infection to the pericardium - -true Smooth muscle fibers differ from skeletal muscle in that they do not contain contractile myofilaments - -false The urethra contains an internal sphincter of smooth muscle - -true The secondary oocyte is ovulated from the primary (Graafian) follicle and into the fallopian tube - -true The left lung has 3 lobes and the right has 2 lobes - -false The digestive organ primarily responsible for the absorption of water is the large intestine - -true Micturition is a reflex that results when returning parasympathetic nerve impulses cause the sphincter to relax and the detrusor muscle in the bladder to contract - -true The female reproductive cycle includes the ovarian and uterine cycles and includes the hormonal changes that accompany these cycle - -true Humans have 32 deciduous teeth - -false Urine flows from the kidneys to the bladder by gravity and peristalsis - -true When it is cold, the cremaster muscle contracts to keep sperm warm - -true When the diaphragm contracts, it raises the floor of the thoracic cavity upward - -false Mucosa-associated lymphoid tissue (MALT) is primarily located within the submucosa - -false The epithelial cells of the distal convoluted tubule have an abundance of absorptive microvilli - -false The ovaries are called the gametes - -false In females, the urinary bladder lies anterior the the vagina and uterus - -true BIO201 BIO201 Stretching of the anal sphincter initiates the defecation reflex - -f
