DISORDERS OF THE CIRCULATORY SYSTEM

Biology - Human Health and Diseases

DISORDERS OF CIRCULATORY SYSTEM - Class 12 Biology - Pre-Medical - Human Health and Diseases #NEET #Biology #HeartDiorders #biology


Following are the diseases that can affect the circulatory system:

Hypertension:

It is the most common disease affecting the heart and blood vessels. A blood pressure of 120/80 mmHg is considered normal. But the increase in blood pressure beyond 140 mmHg (systolic) and 90 mmHg (diastolic) is called high blood pressure (hypertension). A diet full of oily food is known to increase cholesterol levels, causing thickening of the arteries which results in high blood pressure. Tobacco smoking increases the heart rate, contracts blood vessels and raises blood pressure. High blood pressure can harm the heart, brain, kidneys and eyes.

1. Elasticity: 

It is the property of a material by which it tries to regain its original configuration after the removal of the deforming force applied to it. Example of perfectly elastic solid, quartz, phosphor, bronze.


2. Plasticity:

It is the property of a body by virtue of which it does not regain its original shape and size even after the removal deforming force, is called plasticity.

Structure of Atom


1. Discovery of Electron — Discharge Tube Experiment:

In 1879, William Crooks studied the conduction of electricity through gases at low pressure. He performed the experiment in a discharge tube which is a cylindrical hard glass tube about 60 cm. in length.


Mass of electron = 9.109534 x 10⁻³¹ kg

Charge on a electron = (-) 1.602 x 10⁻¹⁹ C

 

2. Properties of Cathode Rays

Physicists and Their Major Contributions (#class11Physics)(#Class12Physics)(#NEET)(#JEE)(#Physics)(#eduvictors)


For Class 11/Class 12 Physics - NEET - JEE

Physics deals with the study of the basic laws of nature and their manifestation in different phenomena. The basic laws of physics are universal and are applied in widely different contexts and conditions. Physics is a basic discipline in the category of natural sciences which also includes other disciplines like Chemistry and Biology. The word physics comes from a Greek word meaning nature.

Here is a partial list of Physicists and their contributions in various fields of physics.
