15- Fats are stored in which part of the body?
The aorta is the largest artery in the body.
* It begins at the top of the left ventricle.
* It carries blood away from the heart to the rest of the body.
* We can keep our Aorta healthy by keeping our blood pressure in control.
* It is the heart that pumps blood from the left ventricle into the aorta through the aortic valve.
* The pituitary is an important gland and is referred to as the ‘master gland’ in our body.
* This gland controls several of the other hormone glands.
* It is about the size of a pea and attached to the base of our brain by a thin stalk.
* It is situated in a bony hollow, that is just behind the bridge of our nose.
3-The Spinal Cord.
* Reflex action is involuntary. It is an automatic and fast movement.
* It is instantaneous movement in response to a stimulus.
* blood-clotting proteins generate thrombin. It is an enzyme that converts fibrinogen to fibrin.
* Fermentation is the process by means of which a substance breaks down into a simpler substance.
* Fermentation is also a metabolic process by means of which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid.
6-Diphtheria, whooping cough, and tetanus.
* DPT (also known as DTP and DTwP).
* It is a combination of vaccines against three infectious diseases in humans. They are diphtheria, pertussis (whooping cough), and tetanus.
* The Scurvy disease occurs due to a vitamin C deficiency.
* A Scottish doctor James Lind was given the credit for discovering the Scurvy in 1747.
* The medulla oblongata forms the hindbrain.
* Breathing, digestion, heart, and blood vessel function, swallowing, and sneezing are controlled by Medulla Oblongata.
* The spinal cord is a long, thin, tube-like structure composed of nervous tissue.
* This structure extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.
* Cerebrum is the principal and most anterior part of the brain. It is the largest part of the brain.
* Cerebrum is the superior part of the brain which is the seat of reason, memory, planning, and sensory integration.
* The cerebellum ( also called little brain) is a major feature of the hindbrain of all vertebrates.
* The cerebellum coordinates voluntary movements like posture, coordination, balance, and speech.
9-It is water dispersed in fat.
* Butter is made by churning fresh or fermented cream or milk to separate the butterfat from the buttermilk.
* The density of butter is 911 grams per Litre (0.950 lb per US pint).
* The common Ostrich are native to certain large areas of Africa.
* Scientific name: Struthio camelus.
* Speed: 70 km/h (Maximum).
* They can grow up to 9 feet (2.7 meters) tall and can weigh up to 320 lbs. (145 kilograms).
* Ostriches are omnivores, which means they eat both vegetation and meat.
* Reptiles are tetrapod animals.
* Nearly all reptiles are cold-blooded(Ectohtermic) and lay shelled eggs.
* The reptiles live in a wide range of habitats.
* Reptiles Are Vertebrates.
12-A Genetic disorder.
* Hemophilia is an inherited genetic disorder.
* People having hemophilia may bleed for a longer time after an injury.
* Hemophilia A is also known as classic hemophilia or factor VIII deficiency.
* Hemophilia B is also known as Christmas disease or factor IX deficiency.
* Bile is a dark green to a yellowish-brown fluid.
* It is produced by the liver which helps in the digestion of lipids in the small intestine.
* Bile has bile acids and salts, pigments, phospholipids, water, and electrolyte chemicals as its composition.
* By secretion into bile, Many waste products, including bilirubin, are eliminated from the body.
* The liver is a dark reddish-brown organ. It is located in the upper right portion of the abdominal cavity.
* The liver lies beneath the diaphragm and on top of the stomach, right kidney, and intestines.
* The liver mainly filter the blood that comes from the digestive tract, before passing it to the rest of the body.
* The arteries are the blood vessels that carry the oxygen-rich blood from the heart to other tissues of the body.
* The Veins are blood vessels that transport blood toward the heart.
* Most veins transport the deoxygenated blood from the tissues back to the heart.
* Normal blood pressure is less than 120 over 80 (120/80).
* A top number (systolic) and bottom number (diastolic).
* Blood Pressure is measured by a sphygmomanometer.
* The instrument is also known as a blood pressure meter, blood pressure monitor, or blood pressure gauge.
* Adipose tissue is also known as body fat.
* It is a highly active metabolic and endocrine organ.
* The adipose tissues are of two types. One is white adipose tissue (WAT), that stores energy. Another one is brown adipose tissue (BAT), that generates body heat.
