Bile juice is bitter, greenish liquid is produced in the liver and deposits in the gallbladder, which dissolve fat.

It is essential for absorption of fat and fat-soluble vitamins (A, D, E & K), digested lipids/fats (monoacyl glycerol and fatty acids), cholesterol, etc.

The appendix is ​​located in the lower right side of your stomach. It is a finger-shaped, thin, nearly 4 inch tall tube, which is part of your gastrointestinal tract.
The appendix a special type of tissue that is connected to the lymphatic system, which takes the necessary white blood cells to fight the infection.

The appendix does not help directly with digestion. It is not clear what role the appendix has in the body, and removal of the organ doesn't show any negative health consequences.

Sometimes, the appendix can become inflamed and infected, which result of an abdominal infection that has spread to the tiny organ, or some kind of obstruction that has blocked the small opening of the appendix.the resulting condition called appendicitis.

The infection or inhibition causes the bacteria in the appendix to grow out of control, and the organ can fill with pus and swell. which causes acute abdominal pain and other GI symptoms, including vomiting and diarrhea.
Removal of the appendix (an appendectomy) is often the necessary course of action, although antibiotics may be recommended and used to treat the infection without the need for surgical intervention that depending on the severity of the case and other health of the patient.

If the problem is left untreated, the pressure in the organ will increase until the appendix ruptures, or bursts.When the appendix bursts, it spreads its content throughout the abdomen, potentially infecting the peritoneum, which is the silk-like membrane that lines the abdominal cavity. A peritoneum infection, called peritonitis, can then lead to sepsis, a complication that's potentially deadly if not treated aggressively.

Plants are green due to green pigment called chlorophyll. This pigment absorbs light and converts it into energy that it uses for metabolism. this process is called photosynthesis.

There are two types of Chlorophyll pigments:
1. Chlorophyll A: It absorbs a lot of red light.
2. Chlorophyll B: It absorbs some blue light and some red light.

Photosystem most aborbs infrared and red light (540nm-630nm) and this is the reason that photosynthesis is maximum in red light.

Anabolic processes are the processes that form compounds. That means higher energy bonds are created.

Photosynthesis is the process of CO2 and H2O are combined with the help of sunlight to form the large glucose molecule. This means that Photosynthesis is a anabolic process because it takes small molecules to form complex molecule.

Anaerobic Respiration: In this type of respiration, partial oxidation of food takes place and energy is released in the absence of oxygen. This type of respiration occurs in prokaryotic organisms like bacteria and yeast.
Ethyl alcohol and carbon dioxide are formed in this process.

Cockroaches do not have lungs. In fact, all the insects like Cockroache are draw air through external valves called spiracles and transport the air directly to the cells via tubes called trachea. To stop breathing, they simply close the spiracles.

Erythroblastosis fetalis also known as hemolytic disease of the newborn, occurs due to Rh incompatibility between mother and fetus , resulting in several anemia and sometime death of fetus.

Rh incompatibility may develop when a woman with Rh-ve negative blood gets pregnant by a man with Rh+ve positive blood and conceives a fetus with Rh+ve positive blood.
This can cause jaundice and other, more serious complications in the new born, including possible heart failure.

treatment
If a baby experiences erythroblastosis fetalis in the womb, treatments include blood transfusion, IV fluid, immunoglobin, and address any difficulty in breathing to new born.

prevention
A preventive treatment known as RhoGAM or Rh immunoglobulin, by providing Rh immunoglobin to a pregnant woman to can reduce a mother’s reaction to their baby’s Rh+ve positive blood cells, blocking Rh sensitization can help prevent the situation.

The original cavity of the mid-brain vesicle is represented by a fine canal, the iter or aqueduct of Sylvius, which is continued behind into the fourth ventricle, and opens in front into the third ventricle.

Urea is the principal nitrogenous waste product of metabolism and is generated from protein breakdown.

It is eliminated from the body almost exclusively by the kidneys in urine, and measurement of its concentration, first in urine and later in blood.

The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle.Blood is pumped from the left ventricle into the aorta and from there branches to all parts of the body.
The aorta branches into a network of smaller arteries that extend throughout the body.

Hemoglobin is the main protein in mature red blood cells.The major role of hemoglobin is to carry oxygen from the lungs to the tissues and return carbon dioxide (CO2) from the tissue to the lungs.

hemoglobin can result in the following disorders:

Iron deficiency anemia
Lead poisoning
Thalassemia
Sideroblastic anemia

The Lacertidae are the family of the wall lizards, true lizards, or sometimes simply lacertas, which are native to Europe, Africa, and Asia.

Some fruits and seeds have hook-like projections, bristles, hairs, spines, which helps them to get attached to the animal skin, hoofs or body parts and get dispersed to other places.

Except for Crocodile, which have a four-chambered heart, all reptiles have a three-chambered heart.

Cholera is caused by a bacteria called Vibrio cholera and is usually spread through contaminated drinking water or food.

Symptoms of cholera dehydration include watery diarrhea and vomiting, due to which such people can recover quickly.
Dehydration can lead to a rapid loss of minerals in your blood that maintain the balance of fluids in your body.
