1
Their branchial gut also opens directly outwards by a pair of branchial clefts.
2
The head contains in the ventral half the branchial gut, the trunk the hepatic gut.
3
Our lungs, trachea, and larynx are formed from the ventral wall of the branchial gut.
4
But the branchial gut, the one reminiscence of our fish-ancestors, is afterwards atrophied as such.
5
Transverse section of the branchial gut.
6
The branchial gut (br), which is pierced by a number of clefts, continues below in the visceral gut.
7
The chief of these is the branchial gut (Figure 2.245 k).
8
In both forms the gut is of substantially the same construction; the anterior section forms the respiratory branchial gut, the posterior the digestive hepatic gut.
9
It divides presently into two sections- awidefore or branchial gut that serves for respiration, and a narrower hind or hepatic gut that accomplishes digestion.
10
The fore chamber is the head-gut or branchial gut (Figures 1.98 to 1.100 p, k), and is chiefly occupied with respiration.
11
The head-gut or branchial gut forms a broad gill-crate, the grilled wall of which is pierced by numbers of gill-clefts (Figure 2.210 d).
12
In this the muscles and skeletal parts of the branchial gut separate; a blood-vessel arch rises afterwards on their inner side (Figure 1.98 ka).
13
The branchial gut lies free in a spacious cavity filled with water, which was wrongly thought formerly to be the body-cavity (Figure 2.216 A).
