The female organs consist as a rule of twocaecal tubes which unite before opening to the exterior.
The Redia has anteriorly a mouth leading into a muscular pharynx and thence into a caecal stomach.

In certain Marsupials with well-developed caecal pouches, such as Phascolarctos and the Vulpine Phalangers (Figs.
The function of the caecal apparatus may be defined as follows: 1.
The caecal pouches are more completely differentiated, communicating with the colon by a constricted neck.
It follows the direction of the caecal curve for 2.
Further development leads to an enlargement of the caecal pouch and a sharper demarcation between the same and the appendix.
In Teleostei, the Sturgeon and Lepidosteus there opens into the front end of the intestine a number of caecal pouches known as the pancreatic caeca.
This part of the alimentary tract was probably provided with pairedcaecal pouches with their blind ends in contiguity with the skin.
By these causes there appeared to be a complete obstruction at a point about six inches above the ileo-caecal valve.
In chronic cases of intussusception, which usually embrace the ileo-caecal and colic varieties, strangulation is not common and the course of the disease is protracted.
In the ileo-caecal form it is twisted or much convoluted rather than bent.
They may cover patches of the mucosa or the whole mucosa from the ileo-caecal valve to the rectum.
When we remember that the ileo-caecal valve is furnished with a sphincter muscle, the analogy is complete.
In bad cases the whole course of the colon from the ileo-caecal valve to the rectum may constitute one vast tract of suppuration.
This name is applied to the numerous fine caecal tubes of noticeable length developed from the proctodaeal invert of ectodermal origin in Hexapods.
Such renal caecal tubes seem to be readily evolved from either metenteron or proctodaeum when the conditions of the out-wash of nitrogenous waste-products are changed by the transference from aquatic to terrestrial life.
The caecum and colon laid open to show the ileo-caecal valve.
The caecum is the commencement of the large intestines, it is a large blind pouch situated below the ileo caecal valve.
The small intestine is a convoluted tube, extending from the pyloric end of the stomach to the ileo-caecal valve where it terminates in the large intestines.
The ileo caecal valve is the valve between the exit of the small intestines and the commencement of the large intestines.
The origin and many of the peculiarities of the ileo-caecal valve find their best explanation on this hypothesis.
The oesophagus opens directly into a very large cardiac sac the distal extremity of which forms a long caecal pouch.
The caecum is a blind sac occupying the right iliac fossa and extending down some two or three inches below the ileo- caecal junction.
The right one is the most valuable, as the ileo-caecal valve is situated where it cuts the intertubercular line, while the orifice of the vermiform appendix is an inch lower down.
At its termination the ileum opens into the large intestine at the ileo-caecal valve.
He knew the ileo-caecal valve; and his description of the duodenum, ileum and colon shows that he was better acquainted with the site and disposition of these bowels than any of his predecessors or contemporaries.
This line corresponds to the body of the fifth lumbar vertebra, and passes through or just above the ileo-caecal valve where the small intestine joins the large.
In most birds, the hind-gut is relatively very short, and the caecal position, accordingly, is at a very short distance from the posterior end of the body.
The ascending colon runs up from the caecum at the level of the ileo-caecal valve to the hepatic flexure beneath and behind the right lobe of the liver; it is about 8 in.
The caecal wall is in most cases highly glandular and contains masses of lymphoid tissue.
Guarding the opening of the ileum into the caecum is the ileo-caecal valve, which consists of two cusps projecting into the caecum; of these the upper forms a horizontal shelf, while the lower slopes up to it obliquely.
Chyle: the food-mass after it has passed through the guard and is mixed with the secretions of the salivary glands and caecal structures, ready to be assimilated.
Caecum: a blind sac or tube-like structure serving as one of the caecal tubes or pouches: see coecum.
Caecal tubes or pouches: sac, or blind tube-like structures surrounding the chylific ventricle at its junction with the crop, and secreting a digestive ferment.
The central capsule in the Diplosphaerida is usually enclosed in the inner shell; often it completely fills up the latter, or drives out a caecal protuberance through each mesh; but these processes rarely unite outside.
From the central capsule arise numerous club-shaped apophyses or caecal sacs, which are protruded through the meshes of the inner shell, x 300 Fig.
Very much of him, too much perhaps, had gone into the acquirement and perfect performance of the caecal operation; the man one met in the social world was what was left over.
The central capsule, originally enclosed in the cephalis, develops usually three or four large pear-shaped caecal sacs which pass through the cortinar pores and depend into the thorax (Pl.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "caecal" in a variety of sentences. We hope that you will now be able to make sentences using this word.
