The liver has a thin capsule of dense connective tissue, and a visceral (inferior) layer of peritoneal mesothelium, and is divided into left and right lobes.

HISTOLOGY OF LIVER

This is a section through a rabbit liver, which is more like that of a human liver. The lobules are far less obvious, but try to identify them, together with portal veins and portal tracts.

In this section of rabbit liver, the lobules are not defined by a layer of connective tissue, as found for the pig. This arrangement is more typical for most mammals, including man. However, lobular structure still present.

Can you identify the portal tracts and central veins.

The liver has very little connective tissue, which explains its softness, and susceptibility to tearing in abdominal trauma. however, a fine network of connective tissue fibres supports the hepatocytes and sinusoid lining cells.

Look at this picture, in which the network of fibres has been stained histochemically.

This shows the central hepatic vein, and the supporting reticulin fibres, which are made of type III collagen.

HUMAN EAR:--
The ear is a sensitive organ of the human body.

It is mainly concerned with detecting, transmitting and transducing sound.

Maintaining a sense of balance is another important function performed by the human ear.

Let us have an overview of the structure and functions of the human ear.

Structure of Ear:--
The human ear consists of three parts:

External ear
Middle ear
Internal ear

CIRCLE OF WILLIS:-
The circle of Willis (cerebral arterial circle or circulus arteriosus) is an anastomotic ring of arteries located at the base of the brain. This arterial anastomotic circle connects the two major arterial systems to the brain, the internal carotid arteries and the vertebrobasilar (vertebral and basilar arteries) systems. It is formed by four paired vessels and a single unpaired vessel with numerous branches that supply the brain.

The main function of the circle of Willis is to provide a collateral blood flow between the anterior and posterior arterial systems of the brain. Additionally, it offers the alternate blood flow pathways between the right and left cerebral hemispheres. This way the circle protects the brain from ischemia and stroke in cases of vascular obstruction or damage.

NASAL SEPTUM DEVIATION

The nasal septum is a wall made of cartilage and connective tissue that separates the nasal passages. The nasal passages are lined on either side with mucous membranes.

When the nasal septum is extremely tilted towards one side, it causes one nasal passage to be larger than the other.

Depending on the severity of this difference, nasal blockage, reduced air-flow, and breathing problems can occur. A misaligned septum can also interfere with nasal drainage, leading to an increased rate of infection and postnasal drip.

Trachea
The trachea, commonly known as the windpipe, is the large tube that delivers air from the upper respiratory tract (the nasal passages, throat, and larynx) to the bronchi (the two large airways that branch off into each lung). In the process, it warms and moisturizes the air and catches debris and microbes before they enter the lungs.

The trachea can become infected, inflamed, or damaged. In rare situations, this can lead to tracheal stenosis, in which the trachea narrows and restricts breathing. Tracheal cancer is an extremely rare form of cancer.

Tracheobronchial Tree:-
The tracheobronchial tree is composed of the trachea, the bronchi, and the bronchioles that transport air from the environment to the lungs for gas exchange.

Together, the trachea and the two primary bronchi are referred to as the bronchial tree. At the end of the bronchial tree lie the alveolar ducts, the alveolar sacs, and the alveoli.

Overview
The tongue is a mass of muscle that is almost completely covered by a mucous membrane.
It occupies most of the oral cavity and oropharynx.
It is known for its role in taste, but it also assists with mastication (chewing), deglutition (swallowing), articulation (speech), and oral cleansing.
Five cranial nerves contribute to the complex innervation of this multifunctional organ.
The tongue is a muscular organ formed by a complex arrangement of intrinsic and extrinsic muscles.
