These two vessels in turn divide into many finer vessels throughout the body, and deliver haemolymph to open arterial sinuses where it bathes and oxygenates the tissues.
32.
If the cuticula is broken in any place, some haemolymph would leak out ( maybe more than usually because of the anticoagulant ), but that's it.
33.
Three of the genera of a subtribe of the Paederini are associated with a skin irritation called " Paederus " dermatitis, due to a potent vesicant in their haemolymph.
34.
More recently it has been shown that malaria-transmitting mosquitoes will actively seek out some species of caterpillars and feed on their haemolymph, and do so to their apparent physical detriment.
35.
It is at first soft and pink with drooping wings, but over the course of a few days, the cuticle hardens and haemolymph is pumped into the wings which stiffen them.
36.
For example, in vivo experiments have demonstrated that the fluid secreted by the Malpighian tubules of the desert beetle, Onymacris plana is directed to the midgut for recycling to the haemolymph.
37.
The muscles in a tarantula's legs cause the legs to bend at the joints, but to extend a leg, the tarantula increases the pressure of haemolymph entering the leg.
38.
PTTH is released in response to environmental stimuli and as its name implies PTTH acts on the prothoracic glands, which respond by releasing molting hormone ( an ecdysteroid ) into the haemolymph.
39.
De-oxygenated haemolymph drains into a large venous sinus within the head and foot, which contains the nephridium, an excretory organ with a function similar to that of the vertebrate kidney.
40.
The circulatory fluid of gastropods, known as haemolymph directly bathes the tissues, where it supplies them with oxygen and absorbs carbon dioxide and nitrogenous waste, a necessary waste product of metabolism.
