(CAR) General Biology 1 Flashcards
Main purpose of white blood corpuscles
To combat infection
Total volume of blood in a normal human being is
5-6 liters
Red Blood Corpuscles are formed in
Bone Marrow
Blood does not coagulate(Thicken) inside the body due to the presence of
Heparin
(Heparin is an anticoagulant (blood thinner) that prevents the formation of blood clots. Heparin is used to treat and prevent blood clots in the veins, arteries, or lung. )
Number of bones in the human of an adult
206
Lung are situated in the
thoracic cavity
(the thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia).)
The pancreas secretes
Insulin
The seat of memory in the human brain is located in the
Cortex
Tibia?
A bone found in the leg
The strongest muscle in the human body is found in
Buttocks
(The strongest muscle in the body is debatable. Some physiologists believe it’s the masseter (used for chewing), while others claim it’s the gluteus maximus (buttocks), or the rectus femoris (part of the quadriceps in the thigh).)
Main function of the kidney
To remove waste products from the body
A gene is a
Unit of heredity
Cabbage contain ____ in it
Sulphur
Enzymes help in
Digestion of food
Ptyalin?
An enzyme produce in the salivary glands
Heightened emotion is caused by
Adrenal Gland (The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol.[1][2] They are found above the kidneys.)
The shortest bone in the human body
Stapes
The smallest bone in the human body is the stapes or stirrup bone, located inside the ear. It is about 3 mm long.
The longest bone in human body
The longest bone in the human body is the femoral bone which comprise about 1/4 of the height of an adult)
Balanced diet?
Food nutrient for growth and maintenance
Wisdom teeth grows b/w the age of
34-40
(The wisdom teeth are the last to appear, right at the back of the mouth. They usually appear when you are between 17 and 25, although sometimes they appear many years later)
Lack of ___ causes diabities
Insulin
Biopsy is done on
Tissue taken form a living body
(A biopsy is a medical procedure, during which a small sample of tissue is removed from a part of the body. The sample of tissue is then examined under the microscope to look for abnormal cells.)
Triple Antigen Vaccine?
It is given to children to protect them against Whooping Cough (pertussis). *(DPT (also DTP and DTwP) refers to a class of combination vaccines against three infectious diseases in humans: diphtheria, pertussis (whooping cough), and tetanus. )
A man weighing 96KG consists of approxi ___ liters of water
66.5 liters
What does blood consists of
60% plasma, 40 % corpuscles
Pituitary gland is located just below the
Brain
(The pituitary gland is a pea-sized structure located at the base of the brain, just below the hypothalamus, to which it is attached via nerve fibers. It is part of the endocrine system and produces critical hormones, which are chemical substances that control various bodily functions.)
Mother’s milk lacks
Vitamin C and Iron
Why do we feel drowsy after a heavy meal?
Brain recieves less oxygen as blood rushes to supply oxygen and nutrtion to the contracting stomach and intestines.
Chromosomes?
Made up of DNA as a main component
(a thread-like structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.)
Ribosomes
The part of the cell which is esential for protien systhesis.
(a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins)
Short sightednesss is due to
Elongation of eye balls
(Near-sightedness, also known as short-sightedness and myopia, is a condition of the eye where light focuses in front of, instead of on, the retina. This causes distant objects to be blurry while close objects appear normal.)
There are ____ muscles in human body
700
(Contraction of the skeletal muscles helps limbs and other body parts move. Most sources state that there are over 650 named skeletal muscles in the human body, although some figures go up to as many as 840)
The organ which destroys worn out RBCs in the body of a vertebrate is
Spleen (abdominal organ involved in the production and removal of blood cells in most vertebrates and forming part of the immune system)
*(Red blood cells have a life span of about 120 days. They are formed in the bone marrow and destroyed by the reticuloendothelial cellspresent in spleen, liver, lymph nodes, brain, the heart or even inthe muscles. Spleen is the major site of their destruction.)
The Slaiva helps in the digestion of
Starch
Biological death of a patient means death of tissue of the
Brain
____ hormone contains iodine
Thyroxine
Respiratory centre is situated in
Medulla Oblongata (The medulla oblongata helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation)
In ____ form gulucose is stored in the liver
Ribose
_____ gland is also called adam’s apple
Thyroid Gland
In Human body, legs bones are
Humerus and Femur
Deficiency of calcium leads to
Rickets
Antibodies are
Protiens
(An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses)
Insulin, a protien acts as
A hormone
Largest living bird is
Ostrich
____ is known as the graveyard of RBCs
Spleen
Endocrine Glands?
-Pour their secretion directly into the blood stream
(The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.)
Ligament?
a short band of tough, flexible fibrous connective tissue which connects two bones or cartilages or holds together a joint.
Normal temperature of Human Body is
98.6°F (37°C)
_____ is the strongest muscle of all in the human body
Thigh
Sweat Glands occur in greatest number in the skin of the
Armpits
(There are two to four million sweat glands distributed all over our bodies. The majority of them are “eccrine” sweat glands, which are found in large numbers on the soles of the feet, the palms, the forehead and cheeks, and in the armpits)
