Cleans and lubricates the teeth and oral cavity
Has some antimicrobial activity
Pharynx
Propels food from the oral cavity to the esophagus
Lubricates food and passageways
Esophagus
Propels food to the stomach
Lubricates food and passageways
Stomach
Mixes and churns food with gastric juices to form chyme
Begins chemical breakdown of proteins
Releases food into the duodenum as chyme
Absorbs some fat-soluble substances (for example, alcohol, aspirin)
Possesses antimicrobial functions
Stimulates protein-digesting enzymes
Secretes intrinsic factor required for vitamin B12 absorption in small intestine
Small intestine
Mixes chyme with digestive juices
Propels food at a rate slow enough for digestion and absorption
Absorbs breakdown products of carbohydrates, proteins, lipids, and nucleic acids, along with vitamins, minerals, and water
Performs physical digestion via segmentation
Provides optimal medium for enzymatic activity
Accessory organs
Liver: produces bile salts, which emulsify lipids, aiding their digestion and absorption
Gallbladder: stores, concentrates, and releases bile
Pancreas: produces digestive enzymes and bicarbonate
Bicarbonate-rich pancreatic juices help neutralize acidic chyme and provide optimal environment for enzymatic activity
Large intestine
Further breaks down food residues
Absorbs most residual water, electrolytes, and vitamins produced by enteric bacteria
Propels feces toward rectum
Eliminates feces
Food residue is concentrated and temporarily stored prior to defecation
Mucus eases passage of feces through colon
Digestive Processes
The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation.
The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth. There, the food is chewed and mixed with saliva, which contains enzymes that begin breaking down the carbohydrates in the food plus some lipid digestion via lingual lipase. Chewing increases the surface area of the food and allows an appropriately sized bolus to be produced.
This image shows the peristaltic movement of food. In the left image, the food bolus is towards the top of the esophagus and arrows pointing downward show the direction of movement of the peristaltic wave. In the center image, the food bolus and the wave movement are closer to the center of the esophagus and in the right image, the bolus and the wave are close to the bottom end of the esophagus.
Figure 1. Peristalsis moves food through the digestive tract with alternating waves of muscle contraction and relaxation.
Food leaves the mouth when the tongue and pharyngeal muscles propel it into the esophagus. This act of swallowing, the last voluntary act until defecation, is an example of propulsion, which refers to the movement of food through the digestive tract. It includes both the voluntary process of swallowing and the involuntary process of peristalsis. Peristalsis consists of sequential, alternating waves of contraction and relaxation of alimentary wall smooth muscles, which act to propel food along (Figure 1). These waves also play a role in mixing food with digestive juices. Peristalsis is so powerful that foods and liquids you swallow enter your stomach even if you are standing on your head.
Digestion includes both mechanical and chemical processes. Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva. Although there may be a tendency to think that mechanical digestion is limited to the first steps of the digestive process, it occurs after the food leaves the mouth, as well. The mechanical churning of food in the stomach serves to further break it apart and expose more of its surface area to digestive juices, creating an acidic “soup” called chyme. Segmentation, which occurs mainly in the small intestine, consists of localized contractions of circular muscle of the muscularis layer of the alimentary canal. These contractions isolate small sections of the intestine, moving their contents back and forth while continuously subdividing, breaking up, and mixing the contents. By moving food back and forth in the intestinal lumen, segmentation mixes food with digestive juices and facilitates absorption.

A. an addiction to alcohol.
B. cancer of the liver.
C. inflammation of the liver.
D. scarring of the liver
None of the choices are correct can speed up how fast alcohol leaves your body's system. Cirrhosis is scarring of the liver. Hence, option D and D are correct.
What is Cirrhosis?Cirrhosis is the term used to describe the scarring of the liver brought on by persistent liver damage. The presence of scar tissue prevents the liver from operating normally. Cirrhosis is commonly referred to as end-stage liver disease since it appears after earlier stages of liver damage from conditions like hepatitis.
The average lifespan of patients with compensated cirrhosis may exceed 12 years. Patients with decompensated cirrhosis have a worse prognosis than those with compensated cirrhosis; their typical survival time without transplantation is only about two years.
The defining characteristics of cirrhosis include weakness and exhaustion. Weight loss results from loss of appetite and illness. You might see red spots on your palms and spider-like blood vessels on your skin above the waist.
Thus, option D and D are correct.

IDENTIFY 2 MYTHS YOU DID NOT KNOW, EXISTED?
Answer:
Theogony: Clash of the Titans and the Three Sisters of Fate.
Explanation:
Theogony: Clash of the Titans and the Three Sisters of Fate are the two myths that I think did not existed in the history. Theogony is the myth which tells us how Cronus overthrew Uranus, and then how in turn Zeus overthrew Cronus and his fellow Titans. It also tells how Zeus was the final and permanent ruler of the cosmos. The three Sisters of Fate are Lahkesis, Atropos, and Clotho that is responsible for the fates of every mortal, God, and Titan. According to mythology, Clotho, Lahkesis, and Atropos were the daughters of Erebus and Nyx. I don't think so that these myths occurs in reality.

A 21-year-old woman presents with a 3-month history of a black mole on her right calf. She tells you that the lesion is enlarging and expanding. It began to itch about 3 weeks ago, and it has bled 2 times. She thinks that there may have been a mole near the same spot previously, but she is not certain. Her general health is good; there is no history of chronic illness, hospitalizations, or surgeries. She works as a professional model for a large advertisement agency. She does not take any prescription medication; she does not use tobacco, alcohol, or recreational drugs. Although she has dark hair, she has a fair skin, and she says that she usually burns with even short sun exposure. She does occasionally use a tanning booth prior to modeling events and vacations. There is no family history of skin cancer.
VS stable, she looks anxious, but she is otherwise well.
There is a dark brown-black nodule on the right calf 1 cm in diameter.
On the surface of the nodule, there is a tiny area of crusting. There are no hairs. The nodule is asymmetrical, and its border is sharply demarcated; the color is uniform, and the elevation is regular. There is a narrow (1-2 mm) rim of erythema around most of the nodule. She has a sprinkling (about 25-30 in all) of melanocytic nevi on her trunk and legs. There is no significant local or distal lymphadenopathy. The liver is not palpable. The remainder of the physical examination is unremarkable.
What is the most likely diagnosis?
Answer:
not a doctor or anything but to me the most likely diagnosis is that If she models, and goes for tanning, the mole might have come into contact with some chemical thought that is unlikely.
it can also be that there was prolonged sun exposure on that area which caused the ledion
