Animal Tissue and Anatomy

It is a specialised to connect and anchor various body organs. It can connect bones to each other, muscles to bones, bind tissues and give support to various parts of body by forming packing around organs so that they do not get displaced by body movements.It main function is binding supporting & packing.

It is the simplest tissue and is the protective tissue of the body. The cells of the tissue are tightly packed and it forms a continuous sheet. It covers most of the organs and cavities within the body. It also forms a barrier to keep different body systems separate. The skin and lining of the buccal cavity, blood vessels, alveoli and kidney tubules are made of epithelial tissue.

The muscle tissue form the contractile tissue are made of muscle cells. Movement of body or limbs are brought about by contraction and the relaxation of the contractile proteins which are present in the muscle cells The movement of the internal organs such as heart and alimentary canal, are all caused by muscle tissues

Epithelial tissue is arranged in single or multilayered sheets and covers the internal and external surfaces of the body of an organism. Epithelial tissue functions to protect underlying structures from injury abrasion or pressure, and from infection.

The liver is a large organ located in the upper right portion of the abdominal cavity, beneath the diaphragm.

Ruffini corpuscles respond to sustained pressure and show very little adaptation. Ruffinian endings are located in the deep layers of the skin, and register mechanical deformation within joints, more specifically angle change, with a specificity of up to 2.75 degrees, as well as continuous pressure states.

The excretory organ of cockroach is the malpighian tubules. It is found at the junction of the midgut and hind gut and are about 150 in number. They are fine, yellow coloured and branched threads, present in bundles. They lie freely in the haemolymph. It excretes uric acid.

There is a triangular area, called the trigone, formed by three openings in the floor of the urinary bladder. Two of the openings are from the ureters and form the base of the trigone. Small flaps of mucosa cover these openings, and act as valves, that allow urine to enter the bladder, but prevent it from backing up, from the bladder into the ureters. The third opening, at the apex of the trigone, is the opening into the urethra. A band of the detrusor muscle encircles this opening, to form the internal urethral sphincter.

Malphigian body contains a tuft of capillaries, called glomerulus. The bowman's capsule and the glomerulus together constitutes the renal corpuscle or malpighian body.

Plants often store waste products in leaves, bark, or fruits, and then shed these parts to effectively remove the waste from their system.

Ureters are the ducts that carry urine from the renal pelvis of the kidneys to the urinary bladder for storage.

Henle's loop or loop of Henle is asociated with excretory system. It is a component of nephron in humans, which progresses from proximal straight tubule to distal convoluted tubule (DCT).
