A cavity containing blood. Generally as the result of an injury which ruptures blood vessels, blood is e?used into one of the natural cavities of the body, or among loose cellular tissue, producing a haematocoele.
n. a swelling caused by leakage of blood into a cavity, especially that of the tunica vaginalis, the membrane overlying the front and sides of the *testis. A pelvic haematocoele is a swelling near the uterus formed by the escape of blood, usually from a Fallopian tube in ectopic pregnancy.
Immature developing (L1 and L2) and infective (L3) stages of nematode larvae, e.g. filariasis, hookworm etc.... In filariasis, after an infective blood meal, microfilariae exsheath, penetrate the stomach wall and pass into the haematocoele, from where they migrate to the thoracic muscles of the mosquito. In the thorax, the small larvae become more or less inactive, grow shorter but considerably fatter and develop, after 2 days, into “sausageshaped” forms (L1). They undergo two (2) moults and the resultant third stage larvae (L3) become active. This is the infective stage and is formed some 10 days or more after the microfilariae have been ingested with a blood meal.... l1, l2, and l3
