1. More than 4.5 𝙢𝙞𝙡𝙡𝙞𝙤𝙣 𝙥𝙖𝙩𝙞𝙚𝙣𝙩𝙨 need blood transfusions each year in the U.S. and Canada.

2. 43,000 pints: amount of donated blood used each day in the 𝙐.𝙎 and 𝘾𝙖𝙣𝙖𝙙𝙖.

3. Someone needs blood every two seconds.

4. Only 37 percent of the U.S. population is eligible to donate blood – less than 10 percent do annually**.

5. About 1 in 7 people entering a 𝙝𝙤𝙨𝙥𝙞𝙩𝙖𝙡 need blood.

6. One pint of blood can save up to 𝙩𝙝𝙧𝙚𝙚 lives.

7. 𝙃𝙚𝙖𝙡𝙩𝙝𝙮 𝙖𝙙𝙪𝙡𝙩𝙨 who are at least 17 years old, and at least 110 pounds may donate about a pint of blood—the most common form of donation—every 56 days, or every two months. 𝙁𝙚𝙢𝙖𝙡𝙚𝙨 receive 53 percent of blood transfusions; males receive 47 percent.

8. 94 percent of blood donors are registered voters.

9. Four main 𝙧𝙚𝙙 𝙗𝙡𝙤𝙤𝙙 𝙘𝙚𝙡𝙡 𝙩𝙮𝙥𝙚𝙨: A, B, AB and O.
Each can be 𝙥𝙤𝙨𝙞𝙩𝙞𝙫𝙚 or 𝙣𝙚𝙜𝙖𝙩𝙞𝙫𝙚 for the Rh factor.
AB is the 𝙪𝙣𝙞𝙫𝙚𝙧𝙨𝙖𝙡 𝙧𝙚𝙘𝙞𝙥𝙞𝙚𝙣𝙩;
O negative is the universal 𝙙𝙤𝙣𝙤𝙧 of red blood cells.

10. 𝘿𝙧. 𝙆𝙖𝙧𝙡 𝙇𝙖𝙣𝙙𝙨𝙩𝙚𝙞𝙣𝙚𝙧 first identified the major human blood groups – A, B, AB and O – in 1901.

11. One unit of blood can be separated into several 𝙘𝙤𝙢𝙥𝙤𝙣𝙚𝙣𝙩𝙨: red blood cells, plasma, platelets and cryoprecipitate.

12. Red blood cells carry 𝙤𝙭𝙮𝙜𝙚𝙣 to the body’s 𝙤𝙧𝙜𝙖𝙣𝙨 and𝙩𝙞𝙨𝙨𝙪𝙚s.

13. Red blood cells live about 120 𝙙𝙖𝙮𝙨 in the circulatory system.

14. Platelets promote 𝙗𝙡𝙤𝙤𝙙 𝙘𝙡𝙤𝙩𝙩𝙞𝙣𝙜 and give those with leukemia and other cancers a chance to live.

15. 𝙋𝙡𝙖𝙨𝙢𝙖 is a pale yellow mixture of water, proteins and salts.

16. 𝙋𝙡𝙖𝙨𝙢𝙖, which is 90 percent water, makes up 55 percent of blood volume.

17. Healthy 𝙗𝙤𝙣𝙚 𝙢𝙖𝙧𝙧𝙤𝙬 makes a constant supply of red cells, plasma and platelets.

18. Blood or plasma that comes from people who have been paid for it cannot be used to 𝙝𝙪𝙢𝙖𝙣 𝙩𝙧𝙖𝙣𝙨𝙛𝙪𝙨𝙞𝙤𝙣.

19. 𝙂𝙧𝙖𝙣𝙪𝙡𝙤𝙘𝙮𝙩𝙚𝙨, a type of white blood cell, roll along blood vessel walls in search of 𝙗𝙖𝙘𝙩𝙚𝙧𝙞𝙖 to 𝙚𝙣𝙜𝙪𝙡𝙛 and 𝙙𝙚𝙨𝙩𝙧𝙤𝙮.

20. 𝙒𝙝𝙞𝙩𝙚 𝙘𝙚𝙡𝙡𝙨 are the body’s primary 𝙙𝙚𝙛𝙚𝙣𝙨𝙚 𝙖𝙜𝙖𝙞𝙣𝙨𝙩 𝙞𝙣𝙛𝙚𝙘𝙩𝙞𝙤𝙣

PANCREAS :


• Has both exocrine and endocrine function.

• Contains about 1-2 million islets of langerhans which has glucagon secreting α-cells and insulin secreting β-cells.


• Glucagon : Peptide hormone, stimulates glycogenolysis by acting on liver cells. Also, stimulates gluconeogenesis. Hence called hyperglycemic hormone.

• Insulin : Peptide hormone, acts on hepatocytes and adipocytes to enhance cellular glucose uptake, stimulates conversion of glucose to glycogen (glycogenesis), so decreases blood glucose level called hypoglycemic hormone.

• Deficiency of insulin causes diabetes mellitus in which loss of glucose occurs through urine.

Simple proteins are made up of amino acids only. Additional non-amino groups are absent, Conjugated proteins have non-amino prosthetic groups like metals or ions. Derived proteins are obtained from proteins through denaturation, coagulation and breakdown.

• On the basis of their structure, proteins are divided into - fibrous, globular and intermediate proteins. Fibrous proteins are elongated, thread like structures that have no tertiary structure. Globular proteins are rounded or oval in outline obtained by tertiary and quaternary foldings of polypeptide. Intermediate proteins are neither fibrous nor globular but of intermediate forms and characterstics.

2022-03-16 20:42:01 -> ->
Fe and Fg are in same direction :- a=g+qE/m


-> ->
Fe and Fg are in opposite direction:- a=g-qE/m

-> ->
Fe and Fg are perpendicular to each other=a²=g²+[qE/m]²

Force between two parallel wires having linear charge density λ1 and λ2 is F(on unit length)=2kλ1λ2/d

If Fe=Fg for two Identical charges then q/m=√4π£oG

Locomotion is the movement of an animal as a whole from one place to another (L. locus = place,moveo=to move).

Movement is defined as any visible change of position, exhibited either by whole organism or by any part of the body. Cells of the human body exhibit three main types of movements.

Types of movement:-


Amoeboid movement: - It is exhibited by specialised cells such as macrophages and leucocytes.

Ciliary movement:- It occurs in most of our internal tubular organs which are lined by ciliated epithelium.

Muscular movement:- Movement of our limbs, jaws,tongue, etc .
